A surface ridge of high pressure situated across the western Atlantic waters will continue it's gradual progression eastward, continuing anti-cyclonic flow around the periphery of the ridge.
This will allow for breezy winds to remain out of an easterly direction today, acting to facilitate warm air advection in the low-level as onshore winds bring in an airmass that has been modified and moderated by the warm waters of the Gulfstream.
Simultaneously, we will start to see a gradual increase in moisture as a mid-to- upper level ridge amplifies in the Caribbean and starts to push northward from the Caribbean. PWATs are expected to rise back above 1.0" later today and over 1.5" on Friday. With the region still being dominated by high pressure, both today and Friday will remain predominantly dry but will see increasing cloud cover beginning today and the chance for a few isolated sprinkles mainly along the east coast. Temperatures will begin to rise today as warm air advection occurs with the ridge and will hit the upper 70s to low 80s today before rising further into the mid 80s on Friday.
LONG TERM
(Friday night through next Wednesday)
Issued at 216 PM EST Thu Nov 30 2023
A mid to upper level ridge in the Carribean Sea will continue to push northward towards the region heading into the first part of the weekend. By the second half of the weekend, this mid level ridge will gradually start to flatten out as a mid level trough moves into the Southeastern portion of the Country. At the surface, high pressure will continue to push further into the western Atlantic as a cold front slowly pushes through the Southeast and into Northern Florida by the end of the weekend.
This will allow for South Florida to remain in the warm sector on both Saturday and Sunday with southeasterly flow on Saturday gradually veering to the south southwest on Sunday. As moisture advection proceeds through the weekend, isolated shower activity cannot be ruled out mainly over the east coast as well as the Atlantic waters during this time frame. With winds veering and become south southwesterly, high temperatures will soar into the mid to upper 80s across most areas both Saturday and Sunday.
For early next week, the weakening frontal boundary will approach and move through South Florida as Monday progresses. With the best dynamics and mid to upper level support remaining well off to the north, there will only be a slight chance of shower activity out ahead of the front as it pushes through. Behind the front, winds will become northerly and cold air advection begins to take place allowing for cooler and drier air to move into the region Monday night into Tuesday. High temperatures out ahead of the front on Monday will rise into the lower 80s, however, cooler temperatures will move into the region Monday night into Tuesday.
For the middle of the week, the latest ensemble guidance is hinting at the potential of a deeper trough digging into the Eastern Seaboard with the possibility of a stronger cold front approaching the region. Uncertainty remains high in the forecast during this time frame as guidance remains in disagreement with the timing and strength of the front as it approaches the region.
With this being at the end of the forecast period, this also adds to the uncertainty in the forecast during this time frame. This will continue to be monitored as the week progresses.
AVIATION
(18Z TAFS)
Issued at 1209 PM EST Thu Nov 30 2023
VFR conditions throughout the TAF period with breezy to gusty easterly winds ongoing. Light easterly flow will prevail once again after sunset later today.
MARINE
Issued at 1209 PM EST Thu Nov 30 2023
Winds will continue out of an easterly direction today before shifting to a southeasterly direction by Friday into the upcoming weekend. Seas of 2-4ft are expected in the Atlantic and 1-2ft in the Gulf to end the week and enter the weekend. A few isolated showers over the area waters will be possible as well as moisture increases.
BEACHES
Issued at 1209 PM EST Thu Nov 30 2023
A moderate risk of rip currents will continue into the end of this week for the Atlantic beaches, with a high risk possible on Friday and over the weekend.
