.DISCUSSION...
Issued at 252 PM EST Thu Dec 11 2025

Rest of Today-Saturday... Upper level high pressure across the Great
Lakes area Today will gradually shift eastward and deepen, reaching
Maine and New Brunswick on Friday and Saturday. At the surface, a
low pressure system near Maine today will lift north and eastward
into late week. This will drag an attached dry cold front that is
across the eastern US across east central Florida through the day.
The front is forecast to reach South Florida by late this
afternoon/early evening. Surface high pressure will then build
across the Florida peninsula behind the front on Friday and into
early weekend. Locally, dry conditions will prevail, with no
mentionable rain chances through the period. Drier air will filter
across the area behind the front, with forecast PW values going from
around 0.8" to around 0.5" behind the front and continuing through
Saturday. North to northwest winds around 5-10 mph today will become
light and variable on Friday before becoming northeast to east on
Saturday and increasing to 5-10 mph once again.

The frontal passage will bring cooler air across the area before a
gradual warming trend takes place, with temps remaining seasonable
to below normal for this time of year. Afternoon highs will range
from mid to upper 60s across the north and upper 60s to low 70s
across the south today, before a gradual warming trends starts with
highs in the low to mid 70s across the area on Friday, and mid to
upper 70s on Saturday. Overnight lows will drop into the low to mid
40s west of I-95, and mid to upper 40s to low 50s across the coast
on tonight before warming generally to upper 40s to low 50s on
Friday night, and generally 50s to low 60s on Saturday night.

Sunday-Wednesday... Another upper level low develops over the Great
Lakes region on Sunday before deepening and moving eastward towards
Maine through Tuesday. At the surface, a cold front associated with
the upper level low, will push across east central Florida late
Sunday into early Monday. High pressure will then build across the
Florida peninsula behind the front. Locally, low level moisture will
increase slightly into early next week, with forecast PW values
rising to 0.8-1.1" before drier air begins to filter across the area
Tuesday, dropping PW values to 0.5-0.7". Rain chances return to the
forecast on Sunday ahead of the front as moisture increases across
the area. There is a low (20-30 percent) chance of showers across
the Treasure Coast on Sunday, with a low (20 percent) chance of
lightning storms. Conditions become mostly dry on Monday through
Wednesday, with no mentionable rain chances across land areas.
However, isolated showers will remain possible across the Gulf
Stream waters during that time.

Northeast winds 5-10 mph on Sunday will increase to 8-12 mph with
gusts to 20 to 25 mph on Monday before winds veer easterly and
decrease to 5-10 mph once again on Tuesday. Winds then become east
to southeast on Wednesday with speeds remaining 5-10 mph. Afternoon
highs in the mid to upper 70s on Sunday will cool to mid to upper
60s to low 70s across the north to low to mid 70s across the south
on Monday before slightly warming on Tuesday and Wednesday to low to
mid 70s. Sunday and Monday nights will be the coolest for this
period, with overnight lows in the low to mid 40s north of I-4
corridor, with 50s everywhere else. Overnight lows will then warm
slightly to low to mid 50s across the interior and upper 50s to low
60s along the coast on Tuesday night, and upper 50s to low 60s
across the interior and low to mid 60s along the coast on Wednesday
night.
