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.
Dewpoint temperatures continued to range mostly in the 50’s over the area. Dewpoint temperatures were in the 60’s to the south of the region where the moisture level was higher.
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.
A mid/upper level trough amplifies southward into the Eastern U.S. early next week.
This will support the development of surface Low east of Florida/off the Southeast U.S. coast. A cold front will trail southwest from this low and will move through the region late Monday/early Tuesday.
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.
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!
