For southeast Florida weather, during the overnight hours, it was partly cloudy to cloudy. Winds were west to northwest at less than 10 mph, but became more northwesterly at 5 – 15 mph with higher gusts few hours before sunrise, but then gradually diminished.
Temperatures were mostly in the upper 50’s to low 60’s. There were some middle 50’s further inland.
During the day, the skies were changeable. It varied from mostly sunny to cloudy. Highs ranged from upper 60’s in the more cloudier areas to near 80 where it was mostly sunny. Winds were generally northwesterly at 5 – 15 mph.
A reinforcing cold front will move through the area overnight.
Drier air will move in, but some cloudiness will continue. Cloudiness and rains will be creeping back up again from the south. This will affect mainly the southern portions on Friday and Friday night.
Tonight will be partly cloudy. There is a chance of some rain approaching from the south, but will probably hold off until morning. Lows tonight will be mostly from low to middle 50’s. Some of the colder locations may see temperatures in the upper 40’s.
Winds will be northwest to west at 5 – 15 mph. Seas will be 2 – 3 feet except 3 – 5 feet occasionally 6 feet in at Palm Beach County waters. There will be a north northeast 3 foot swell off the Palm Beach County waters. Intracoastal waters and Biscayne Bay will have a light chop.
On Friday, it will be partly cloudy to becoming cloudy especially in the southern areas. There will be a chance of rain, most likely in the southern areas. Highs will range around 70 to middle 70’s. If there is more clouds/rain, then these highs may be a little lower.
Winds for Friday and Friday night will be northwest at 10 – 15 mph. Seas will be 2 – 3 feet. Palm Beach County waters will be 2 – 4 feet occasionally 5 feet. Intracoastal waters and Biscayne Bay will have a light chop.
Another reinforcing cold front will move through the area on Saturday.
Also an upper level shortwave will be rounding the base of the longwave over the Gulf of Mexico which will result in the longwave trough to deepen and “dig” further south. This longwave trough will move over the area on Sunday. As the axis of the longwave trough moves east and exits the state, conditions will clear out and additional cold air will move in.
The latest suite of models has the 850 mb temperature at 0 – 4 degrees Celsius (32 – 39 F) to occur on Sunday and then rising later on Sunday.
As it has been mentioned in previous posts, the surface temperature can be warmer or colder than the 850 mb level temperatures. Cloud cover, winds (speed and direction) will influence the surface temperature.
It is becoming more likely that there will be some rains/showers associated with the cold event. This is something south Florida does not see often. It will make for a raw day/night. Also winds will be increasing to breezy possibly windy at times.
It will be a mostly cloudy day with periods of cool/cold rain working in from the south. It appears that the most focused area to get rains will be the southern regions (initially) and most prevalent Saturday night through Sunday morning.
For Saturday, clouds will be increasing early becoming mostly cloudy. The chance of rains will be on an increase. The rain will be most likely Saturday night/early Sunday. Highs will be in the 60’s. Depending on cloud cover and rain, these temperatures may vary. Lows will be primarily in the 40’s except low 50’s near the coast of Miami-Dade and Broward Counties.
Winds will be out of northwest at 10 – 20 mph. Seas will average 2 – 5 feet occasionally 6 – 8 feet in the Gulf Stream Saturday night. A small craft exercise caution may be issued for portions of the Atlantic waters.
On Sunday, it will start off cloudy with some rain. It will be cold. Highs will be in the 60’s (if clouds/rain linger longer, would not be surprised that it stays in the 50’s in some areas).
Lows will range from middle 30’s to low 40’s in the Inland areas to middle and upper 40’s near the Coast. There may be more fine tuning of these temperatures. Clouds and winds will influence the temperatures. Winds will not be shifting to a northeast component so there will not be maritime influence. However, the coldest of the air will have moved out.
Winds will be out of northwest at 10 – 20 mph. Seas will average 2 – 5 feet occasionally 6 – 8 feet in the Gulf Stream. A small craft exercise caution may continue for portions of the Atlantic waters.
Next cold front looks to arrive on Wednesday.
It will not be as cold as the weekend cold event.
