DISCUSSION
Issued at 310 PM EDT Mon May 20 2024

Weakening boundary across the area has pretty much washed out with west to northwest flow across all but the northern Nature Coast where flow is northeasterly. A few showers and possibly a thunderstorm remains possible over the southern interior into this evening where moisture is higher, otherwise a couple of sprinkles will be possible across the Nature Coast as the northeast flow gradually spreads southward. These northeast winds will spread south across the entire area overnight with fair dry weather prevailing. On Tuesday, the northeast flow will continue, but light enough that we'll see the west coast sea breeze develop and move inland. Should be enough moisture to allow for some scattered showers and possibly a thunderstorm to develop during the afternoon and evening over the interior and then further west closer to the Interstate 75 corridor as the east and west coast sea breezes collide.

For the remainder of the work week, high pressure will build over the area with warming temperatures and rather dry conditions anticipated. Only exception may be over the southern interior and southwest Florida where just enough moisture could combine with daytime heating and the sea breezes to allow a few afternoon and evening showers and possibly a thunderstorm each day. High temperatures will climb into the mid 90s away from the coast each day with the sea breeze keeping coastal location in the upper 80s to near 90. Overnight lows will be a little lower then they have been recently thanks to the drier air, but still close to normal for mid to late May.

Over the weekend, an upper level shortwave is expected to move across the southeast U.S. suppressing the ridging and allowing some deeper moisture to spread across the entire area. However, this will also mean that the low level flow will shift to a more south to southwest direction so that the highest rain chances will be over the interior and eastern half of the Florida peninsula.

AVIATION
(18Z TAFS)
Issued at 310 PM EDT Mon May 20 2024

VFR conditions are expected through the period with west to northwest winds diminishing and shifting to northeast early tonight.

MARINE
Issued at 310 PM EDT Mon May 20 2024

Weak high pressure gradually builds over the waters during the week with east to southeast flow setting up, except shifting to onshore with the sea breeze each afternoon. No headlines are expected.

FIRE WEATHER
Issued at 310 PM EDT Mon May 20 2024

Some drier air will filter into the area during the week with highest rain chances, albeit less than 30 percent, over southern interior and southwest Florida by midweek. Relative humidity values will remain above critical levels with winds 15 mph or less. Higher dispersions will be possible over the next few afternoons over inland areas, otherwise no concerns are expected.
