DISCUSSION
Issued at 301 AM EDT Mon May 13 2024

The work week will start out quite a bit more humid compared to yesterday as deeper moisture returns. As the high pressure moves further over the Atlantic the flow becomes more S/SE and winds increase as the gradient tightens. Rain chances also increase tomorrow as the sea breezes collide along the interior. Some storms developing along these boundaries could become severe as extra energy provided by mid-level impulses move over the area, supporting elevated CAPE values and effective bulk shear. With all these ingredients coming together, Storm prediction Center has placed portions of our CWA in a marginal risk for severe weather this afternoon. Main concern will be along the nature coast and the interior where sea breeze collisions are expected. Main threat will be for hail, damaging wind gusts and a possible tornado.

Tuesday into Wednesday, a shortwave trough moves east scraping across northern portions of the peninsula. A surface low with accompanying this short wave is expected to move over the area bringing another round of showers and storms. SPC has also marked areas mainly north of I4 as a marginal risk for severe thunderstorms, Tuesday and portions of Levy county and areas northward, Wednesday.

Conditions begin to dry out Thursday into Friday as ridging tries to build back over the area. Temperatures remain on the above average side, with highs in the low to mid 90s more most areas.

AVIATION
(06Z TAFS)
Issued at 301 AM EDT Mon May 13 2024

Vfr conditions prevail. SE winds will begin to increase and move onshore by the afternoon. Some afternoon convection is likely, but will likely occur inland, away form most terminals, except maybe LAL. Tuesday into Wednesday more showers and thunderstorms are possible, especially for areas north of I4 and inland.



MARINE
Issued at 301 AM EDT Mon May 13 2024

Pressure gradient tightens today allowing for increased SE winds that will turn onshore as the sea breeze develops. Scattered showers and thunderstorms will move into northern waters beginning tonight with another round likely tomorrow into Wednesday.
Increased winds will also support increased wave heights.
Unfavorable marine conditions will likely last until the end of the week.

FIRE WEATHER
Issued at 301 AM EDT Mon May 13 2024

No major fire weather concerns through the week as RH values remain above critical levels. Shower and thunderstorms are expected to move over portions of the CWA beginning tonight and continuing through Wednesday.
