.SHORT TERM...
(Tuesday through Wednesday night)
Issued at 157 PM EDT Mon Jul 8 2024
High pressure continues to dominate the region with a synoptic
west-southwesterly flow pattern pinning the Atlantic sea breeze
pretty close to the east coast. Convection will start up along the
Gulf and push inland in the late morning to early afternoon
hours, later interacting with the Atlantic sea breeze prompting
numerous showers and thunderstorms across NE FL and SE GA.
Westerly flow will continue on Wednesday, with PWATs remaining
near 2.0", again numerous showers and thunderstorms will develop
by afternoon across the area. Heavy rainfall and training storms
may pose local flooding issues, especially in urban areas and
locations with poor drainage.
Temperatures will be just below to near normal Tuesday and
Wednesday, with heat indices overall expected to remain just below
Heat Advisory criteria.
&&
.LONG TERM...
(Thursday through next Monday)
Issued at 157 PM EDT Mon Jul 8 2024
A front will approach from the northwest on Thursday, later
stalling over central Georgia and dissipating Saturday.
Southwesterly steering flow paired with moisture ahead of the
front will allow for PWATs over 2.0" area-wide. Steering flow will
shift more southeasterly Friday night as high pressure builds
over the Atlantic. Numerous showers and thunderstorms will develop
each afternoon, with the highest coverage over north central
Florida where sea breezes interact.
Temperatures will be near normal on Thursday and Friday, rising to
above normal for the weekend, with highs in the the lower to mid
90s.
