Analysis:

For southeast Florida weather, during the overnight hours, it was generally partly cloudy with some locations reporting clear conditions while other areas reporting cloudy conditions at times.  Scattered light showers were streaming southwest from the Atlantic and onshore just north of Palm Beach County.  Other showers were located between the southeast coast and the western Bahamas and the Florida Straits, south of the Florida Keys.

It was a rather cool night with lows mostly upper 50’s to low 60’s.  Areas closer to the coast in Miami-Dade and Broward Counties were in the middle 60’s to near 70. Areas well inland, (primarily in Palm Beach County) had lows in the low to middle 50’s.  An interesting note, as onshore winds in West Palm Beach veered to offshore (land breeze), the temperature went from 71° at 2:00 am to 60° at 3:00 am.  This was an 11 degree drop in one hour with the passage of land breeze boundary.  Another point of interest is at 11:00 pm, it was 73° at West Palm Beach while at the same time it was 64° at Miami (thanks to the Miami NWS with the notification).  Winds were light northeast early except up to 10 – 15 mph with higher gusts near the coast.  As the night progressed, the winds became more northwest and north at light speeds.

During the day, it was sunny to partly sunny early.  Clouds were increasing to becoming most partly cloudy to cloudy except for the northern portions (Palm Beach County) as the cloudiness had not reached the area.  Isolated to widely scattered showers continued streaming in from the Atlantic north of Palm Beach County.  Other sprinkles/light showers were occurring over portions of the region during the afternoon.

Highs were generally in the middle and upper 70’s.  Winds were mostly northeasterly at 15 – 20 mph with gusts up to 25 mph especially near the coast.

With northeast winds transporting moisture from the Atlantic into the region, the low to mid-level moisture increased since Thursday.  Note the higher moisture level in the western Bahamas and Florida Straits.

Forecast:

Short Range Forecast:

For tonight, it will be generally cloudy.  It will be breezy at the coast.  There will be isolated to widely scattered showers mostly light showers, generally later tonight.  Lows will be in the low to middle 60’s inland to middle and upper 60’s toward the metro and coastal areas.  Some areas near the immediate coastal sections will be around 70.  Some areas well inland (especially in Palm Beach County) may see in the upper 50’s to around 60.

Winds will be northeast at 15 – 22 knots.  Seas will be 4 – 7 feet.  Intracoastal waters and Biscayne Bay will be choppy in exposed areas.  Small Craft Advisory is in effect except for Biscayne Bay.

 

Moderate to fresh winds will continue into the early portion of the weekend before subsiding toward the later portion of the weekend.  A Small Craft Advisory is in effect and will continue to at least Saturday morning.

With these onshore winds, there will be a high risk of rip currents.  A Rip Current Statement has been issued.

With a northeast and east northeast wind flow, moisture will continue traversing the area.  This plus even higher moisture to the south will lead to isolated to widely scattered showers through the weekend.

The chance of showers will continue until the front passes through the area.  Minor cooling will take place behind the front.  Temperatures will generally fall to the 50’s to middle 60’s behind the front.

 

For Saturday, it will be partly sunny to partly cloudy.  It will be breezy especially near the coast.  There will be isolated to widely scattered showers.  Highs will be around upper 70’s to low 80’s.  Lows Saturday night will be in the middle 60’s to low 70’s.  Some areas well inland (especially in Palm Beach County) may see lows around 60 to low 60’s.

Winds will be northeast at 15 – 20 becoming east northeast Saturday night.  Seas will be 4 – 7 feet and occasionally up to 9 feet in Palm Beach County.  Intracoastal waters and Biscayne Bay will be choppy in exposed areas.  Small Craft Advisory in effect through 10:00 AM except for Biscayne Bay where small craft operators should exercise caution.  Small Craft Advisory may be extended.  Small craft operators exercise caution may be in effect.

With the fresh onshore winds, there is high risk of rip currents.  A Rip Current Statement has been issued.

For Sunday, it will be partly sunny to partly cloudy.  There will be isolated to widely scattered showers.  Highs will be around 80 to low 80’s.  Lows Sunday night will be in the low to middle 60’s inland to middle and upper 60 toward the metro and coastal areas.  Some areas well inland (especially in Palm Beach County) may see lows in the upper 50’s to low 60’s.

Winds will be east northeast at 8 – 15 knots becoming variable less than 5 knots Sunday night.  Seas will be 2 – 4 feet and 4 – 6 feet in Palm Beach County.  Sunday night, seas subside to 2 – 4 feet.  Intracoastal waters and Biscayne Bay will have a moderate chop subsiding to light chop Sunday night.

For Monday, it will be partly sunny to partly cloudy.  There will be isolated to widely scattered showers.  Highs will be in the upper 70’s to low 80’s.  It will turn a little cooler Monday night.  Lows will be in the upper 50’s to low 60’s in Palm Beach County.  For Miami-Dade and Broward Counties, lows will be in the upper 50’s to low 60’s inland to low 60’s and middle 60’s in the metro and coastal areas.  Some areas well inland (especially in Palm Beach County) may see lows in the low to middle 50’s.

Winds will be west and northwest at 9 – 14 knots becoming northwest and north northwest at 10 – 18 knots Monday night.  Seas will be 2 – 3 feet except increasing to 3 – 5 feet offshore in Palm Beach County Monday night.

 

Medium Range Outlook:

With a general northerly flow with frontal passage, there will be less moisture and shower activity looks to be minimal.

A mid/upper level ridge will be building northward into the Southeast U.S.

 

500 mb (Mid-Level) Flow 12-06-13

500 mb (Mid-Level) Flow 12-06-13

 

With this pattern setup, systems progressing eastward from the western U.S. will tend to be deflected up and over rather than weakening/shunting away the High.  This will lead to general tranquil weather and above normal temperatures (after temporary cool down) for at least a few days after the next frontal passage.

 

Extended Range Outlook:

Looking further out, with general mid/upper level ridging near the area, temperatures will continue to be above normal.  According to the GFS forecast model, there is the potential of a frontal system around the middle of the following week (week of 12/8).

This is a long way out and is subject to large errors.  It also appears at this time, that the surface High will shift rapidly to the east resulting in winds veering quickly to the northeast and thereby the cooler air quickly modified by maritime influence of the Atlantic and Gulf Stream.

 

Have a Great Weekend!

Happy Thanksgiving!

 

Analysis:

For southeast Florida weather, during the overnight hours, it was mostly clear to partly cloudy.  Few locations reported cloudy conditions at times.  No showers were detected on radar.

It was cool/cold.  Lows were mostly in the middle and upper 40’s in Palm Beach County.  In Miami-Dade and Broward Counties, lows were upper 40’s to low 50’s with a few locations in the middle 50’s.  Some areas well inland were in the low to middle 40’s mainly in Palm Beach County. Below is a snapshot of temperatures at 7:00 am and it is not necessarily the overnight lows.

 

South Florida Temperatures - 7:00 am

South Florida Temperatures – 7:00 am

 

Winds were mostly northwesterly at 8 – 15 mph with occasionally higher gusts at times.

Temperatures could have been colder as this was not an ideal setup for maximum radiational cooling due to the clouds and wind.  Optimal radiational cooling setup would have been clear skies and calm winds.   However, the winds did make it feel a few degrees colder.

During the day, it was sunny to mostly sunny.    It became partly sunny to partly cloudy during the afternoon. Isolated showers had formed in the Florida Straits with movement to the southwest.  Note below the cloud pattern due to the cooler/colder air moving over the warmer waters of the Atlantic and Gulf Stream.

By late morning, temperatures had risen to the upper 50’s to middle 60’s most areas.   Highs were mostly near 70 to middle 70’s.  Northerly winds during the morning became northeast by early afternoon at 10 – 20 mph with higher gusts.

Very dry air moved into the area.  However, some moistening was occurring at the low and mid-levels as winds veered to the northeast.  Dewpoint temperatures were generally in the 50’s.

Forecast:

Short Range Forecast:

For tonight, it will be partly cloudy to cloudy.  There may be mostly light isolated showers moving ashore.  Lows will be upper 50’s to middle 60’s.  Some of the immediate coastal areas may be in the upper 60’s especially in Miami-Dade and Broward Counties.  Areas well inland (especially in Palm Beach County) may see lows in the low to middle 50’s.

Winds will be northeast at 14 – 19 knots.  Seas will be 4 – 7 feet.  Intracoastal waters and Biscayne Bay will be choppy in exposed areas.  Small craft operators should exercise caution.

 

With the winds veering to the northeast and air mass modification well underway due to the maritime influenced of the Atlantic and Gulf Stream, the warming trend has commenced.  It will be around 10 – 15 degrees warmer for lows overnight than Wednesday night/Thanksgiving Day morning.

Additionally winds coming off the Atlantic, higher moisture will move into the area leading to more clouds and isolated to widely scattered showers.

GFS Wind & Precip Forecast Model 11-28-13(12z) at 051 Hours

 

A surface High will strengthen in the eastern U.S. leading to the tightening of the pressure gradient.  Winds will accordingly increase for Friday and into the early part of the weekend.  The High will move eastward into the Atlantic which will relax the pressure gradient and consequently diminishing winds in the later portion of the weekend and early next week.  Small Craft Advisory and or small craft operators exercise caution may be required for portions if not all of the area.  Additionally, with increasing onshore winds, the risk of rip currents will be at least in the moderate range and possibly high.  A Rip Current Statement may be issued.

For the remainder of the short term period temperatures will gradually warm.  By the weekend, highs should be around 80 to low 80’s range.  Lows will range mostly in the 60’s to around 70.  It will be generally be partly cloudy.  Isolated to widely scattered mostly light showers are possible.

Winds will be northeast at 15 – 22 knots.  Seas will be around 5 – 8 feet.  Intracoastal waters and Biscayne Bay will choppy in exposed areas.  A Small Craft Advisory and or small craft operators exercise caution may be required for portions if not all of the area.  Monitor latest marine forecast.

Additionally, with onshore winds, there will be at least a moderate to possibly high risk of rip currents.  A Rip Current Statement may be required.  An update via twitter will be sent out on Friday with the rip current risk level.

For Saturday, it will be partly sunny to partly cloudy.  There will isolated showers to widely scattered showers. It will be breezy especially near the coast.  Highs will be in the upper 70’s to low 80’s.  Lows Saturday night will be in the middle 60’s to near 70.  Some areas well inland (especially in Palm Beach County) may see lows in the upper 50’s to low 60’s.

Winds will be northeast at 15 – 21 knots diminishing to 11 – 18 knots Saturday night.  Seas will be 5 – 8 feet subsiding Saturday night to 3 – 6 feet and occasionally up to 8 feet in Palm Beach County.  Intracoastal waters and Biscayne Bay will be choppy in exposed areas.  A Small Craft Advisory or small craft operators exercise caution may be required for portions if not all of the area.

Due to onshore winds, there will be at least a moderate to possibly high risk of rip currents.  A Rip Current Statement may be issued.  An update via twitter will be sent out on Saturday with the rip current risk level.

For Sunday, it will be partly sunny to partly cloudy.  There will isolated showers to widely scattered showers.  Highs will be in the upper 70’s to low 80’s.  Lows Sunday night will be low to middle 60’s inland to middle to upper 60’s near the metro/coastal areas.  Some areas well inland (especially in Palm Beach County) may see lows in the upper 50’s to 60.

Southeast Florida Weather – Evening Update 11-27-13

Beach_Image100

 

Analysis:

For southeast Florida weather, during the overnight hours, it was cloudy.  Showers and thundershowers were widespread over the area beginning around/just before midnight.  Several Weather Statements and Special Marine Warnings were issued.  By late night, it became more of a light to moderate rain event as most of the stronger thunderstorms moved offshore.

 

Animated Radar with Satellite Overlaid (Early Morning)

Lows were generally around 70 to low 70’s with some upper 60’s reported.  Some areas well inland primarily in Palm Beach County had lows in the middle 60’s.  Winds were south and southwest at 5 – 15 mph with higher gusts especially near the thunderstorms.

During the day, after a rainy start, most of the activity moved offshore by late morning.   The much anticipated cold front was a little slower than forecast. The front was moving across south Florida during the morning and moved offshore of southeast Florida before Noon and by early afternoon, was moving into the western Bahamas.

Highs were mostly in the middle and upper 70’s.  Temperatures remained near steady through the day after peaking around late morning in most areas.  Winds were west and northwest at 10 – 20 mph with higher gusts.

Drier air was moving in behind the front.  This was reflected in the lower dewpoint temperatures.  Dewpoint temperatures were mostly in the 50’s area wide.  Dewpoint temperatures were in the 30’s in north Florida and 20’s in portions of the panhandle.

Forecast:

Short Range Forecast:

For tonight, it will be clear.  It will be much cooler.  Lows will be in the upper 40’s to middle 50’s.  Some of the immediate coastal areas of Miami-Dade and Broward Counties may be in the upper 50’s.  Some areas well inland (especially in Palm Beach and Broward Counties) may see lows in the middle 40’s.

Winds will be north northwest at 17 – 21 knots.  Seas will be around 5 – 8 feet.  Intracoastal waters and Biscayne Bay will have a moderate chop.  Small Craft Advisory is in effect through Thanksgiving morning except for Biscayne Bay. Small craft operators should exercise caution in Biscayne Bay.

 

After a cool/cold start, Thanksgiving Day morning, winds will veer to the northeast.  As winds veer, the air mass will begin the modification process as maritime influence of the Atlantic/Gulf Stream takes hold.  Consequently, the warming trend will be underway.

With the winds coming across the Atlantic, there will be an increase in clouds.  It may be further enhanced by the relatively cooler air moving over the warmer waters.  Some isolated to widely scattered showers may develop over the Atlantic waters and come ashore.

 

GFS Wind & Precip Forecast Model 11-27-13(12z) at 039 Hours

As a surface High builds into the eastern U.S., the pressure gradient will tighten up.  Winds will accordingly increase.  A Small Craft Advisory and or small craft operators should exercise caution will probably be required for portions if not all of the area.  Additionally, as winds become more onshore and strengthen, the risk of rip currents will increase. There will be at least a moderate risk to probably high risk of rip currents.   A Rip Current Statement may be issued.  Marine interests and beach goers should monitor the latest forecasts.

 

For Thanksgiving Day, it will be cool/cold start under mainly clear skies.  Some clouds will move in later in the day.  It will be partly cloudy to cloudy Thursday night mainly near the coastal areas.  Isolated showers may move ashore.  It will become breezy especially near the coast.  Highs will be around 70 to middle 70’s.  Lows Thursday night will be in the upper 50’s to middle 60’s in the interior areas to middle 60’s to near 70 toward coastal areas.  Some area well inland (especially in Palm Beach County) may see lows around the middle 50’s.

Winds will be north northeast to northeast at 15 – 21 knots.  Seas will be around 5 – 8 feet.  Intracoastal waters and Biscayne Bay will be choppy in exposed areas.  Small Craft Advisory will be in effect until 1:00 pm Thanksgiving Day except for Biscayne Bay where small craft operators should exercise caution.  Monitor latest marine forecast as the advisory and or small craft operators exercise caution may be extended.

As winds become onshore and increase, the risk of rip currents will also increase especially later in the day.  There will be at least a moderate risk to possibly high risk of rip currents.  A Rip Current Statement may be issued.  Monitor the latest forecasts.  An update via twitter will be sent on Thanksgiving Day with the rip current risk level.

For Friday, it will be partly cloudy.  There will be isolated to widely scattered mostly light showers mostly near the coastal/metro areas. It will be breezy to windy at the coast. Highs will be in the upper 70’s to around 80.  Lows Friday night will be mostly in the 60’s except upper 60’s to low 70’s near the coast.  Areas well inland (mainly in Palm Beach County) may see lows around upper 50’s to around 60.

Winds will be northeast at 17 – 23 knots.  Seas will be around 5 – 9 feet.  Intracoastal waters and Biscayne Bay will choppy to rough in exposed areas (especially in the southern area).  A Small Craft Advisory will probably be required for portions if not all of the area.  Monitor the latest marine forecasts.

With fresh onshore winds, there will probably be a high risk of rip currents.  A Rip Current Statement will probably be issued.  Monitor the latest forecasts.  An update via twitter will be sent on Friday with the rip current risk level.

For Saturday, it will be partly cloudy.  It will be breezy especially near the coast.  There will be isolated mostly light showers mainly near the coastal/metro areas.  Highs will be upper 70’s to low 80’s.  Lows Saturday night will be in the middle 60’s to low 70’s.  Some areas well inland (especially in Palm Beach County) may see lows around 60 to low 60’s.

Winds will be northeast at 15 – 20 knots diminishing and becoming north northeast at 10 – 15 knots in Palm Beach County.  Seas will be 4 – 7 feet and occasionally up to 9 feet in the southern portion (Miami-Dade and Broward Counties).  Saturday night, seas in Palm Beach County will subside to 3 – 5 feet.  Intracoastal waters and Biscayne Bay will be choppy in exposed areas subsiding to moderate chop Saturday night in Palm Beach County).

With continuing onshore winds, there will be at least a moderate risk to possibly high risk of rip currents.  A Rip Current Statement may be issued.  An update via twitter will be sent on Saturday with the rip current risk level.

 

Medium Range Outlook:

There will be little change into the weekend with generally sunny to partly cloudy conditions. There may be some isolated mostly light showers. As the surface High weakens, winds will diminish in the latter portion of the weekend and into early next week.

A mid/upper level trough will amplify and dig south over the eastern U.S. early next week.

500 mb (Mid-Level) Flow 12-02-13

 

This will aid in the development of a surface Low near the Southeast U.S. coast.  A weal cold front will move through the region early next week.

 

WPC Forecast 12-03-13 (7:00 am)

WPC Forecast 12-03-13 (7:00 am)

 

Earlier model runs of the GFS forecast model was showing a surface Low traversing across the northern Gulf of Mexico and then across the state.  But in the later runs, it changed its tune and has development off the Southeast U.S. coast.

With the approach of the front, there may be a better chance of showers.  There will only be minor cooling behind the front.

 

Extended Range Outlook:

Looking further out, a mid/upper level positively tilted trough will setup in the western U.S.  This will bring colder and unsettled weather for that region.  Meanwhile, a mid/upper level ridge will tend to build northward into the southeastern U.S.  This will result in above normal temperatures for the Southeast U.S.
