New AVIATION

UPDATE
Issued at 704 PM EST Sun Dec 3 2023

For the latest NE FL and SE GA Daily Key Messages please visit: https:// www.weather.gov/media/jax/briefings/nws-jax-briefing.pdf

Surface front will continue to move southeast across area Tonight, passing to the south Monday morning. With moisture convergence along the front, this will be a cloudy night, with a few spotty showers possible.

Above normal lows are expected, with a range from the mid 50s inland SE GA, to the mid 60s coastal NE FL.

SHORT TERM
(Monday through Tuesday night)
Issued at 315 PM EST Sun Dec 3 2023

Monday, low clouds and patchy to areas of fog will slowly lift as drier west to WNW winds arrive from the NW by midday. The west to NW flow in the mid levels will occur as a strong shortwave moves through the TN valley to the Delmarva region late in the day which will help to keep troughing over the eastern third of the nation.
However, mid and high level clouds will remain overhead as the area stays underneath fast moving jet stream winds streak from the Fl panhandle to the Carolina coast. Westerly surface winds will be elevated 10-20 mph as high pressure builds in from the WNW. Highs will likely occur in the midday hours to around 5 degrees above normal to the low 70s in SE GA and the mid 70s over NE FL before cooling into the 60s by the mid to late afternoon as the cooler and drier airmass arrives.

Monday night, partly cloudy skies and cool WNW winds will lower low to around normal values into the low/mid 40s over SE GA and the upper 40s/lowers 50s over NE FL with mid 50s at the NE FL immediate coastal communities.

Tuesday, high cirrus cloud cover will linger, but light NW winds 10-15 mph will keep highs on the cooler side in the low 60s over SE GA areas and the mid 60s for most of NE FL with upper 60s over north central FL and the St Johns river basin.

LONG TERM
(Wednesday through next Sunday)
Issued at 315 PM EST Sun Dec 3 2023

A drier pattern will be in place for the majority of this period as deep mid/upper level troughing over the appalachian will shift just off the east coast Thursday with deep ridging aloft in it's wake that will move to the east coast on Friday. This will support surface high pressure building south and eastward towards the area from the mid MS valley Wednesday into the deep south on Thursday, then shifting just east of the area over the Atlantic waters on Friday with breezy NW winds Wednesday becoming light and northerly Thursday, then east to southeasterly on Friday with increasing clouds. A new trough will deepen over the central U.S.
Saturday with southeast winds turning southerly and coastal showers then forming as a coastal trough lifts north off the FL peninsula. Flow from the SW will increase moisture levels to 1.25 to 1.5 inches of Precipitable water ahead of an approaching cold front that will move towards the area on Sunday. The GFS and ECMWF models diverge on timing Sunday with the ECMWF much slower than the GFS and will keep at least scattered shower coverage in place to end the weekend.

Highs will be below normal Wednesday through Thursday, then warm to slightly below normal by Friday and then above normal Saturday, before cooling to near normal on Sunday. Lows will be below normal Thursday, with a frost possible away from the coast, then trend to near normal by Saturday morning and above normal Sunday morning ahead of the next cold front.
