New UPDATE, AVIATION

UPDATE
Broken band of weak showers over the I-4 corridor early this morning to slowly sag Sward as E Gulf convection is expected to move ashore through the afternoon hours. Early look at 12Z sounding showing low level inversion that is keeping the activity weak, but fcst CAPE values increase significantly with diurnal heating to keep the mention of strong to severe storms possible especially for well interior areas especially if E Coast seabreeze moves inland.

Another day of long period swell energy from the Yucatan Channel that is again producing 2-3 ft breaking waves and strong rip currents locally especially at SW facing beaches. Beach goes need to be aware this threat is real and there was a fatal drowning yesterday in Manatee County.

AVIATION
(12Z TAFS)
BKN band of SHRA to move over the region this morning/afternoon with a slight chance of TSRA at terminals this afternoon with brief and localized MVFR cigs/vsbys thru around 21Z then improving trend expected this evening/tonight. SW-W winds occasionally gusty today then shift NW and weaken tonight.

DISCUSSION
Issued at 515 AM EDT Sun May 19 2024

Deep layer W-SW flow over the peninsula this morning south of a trough aloft extending from the Mid-Atlantic SW to the N Gulf Coast and an attendant frontal boundary draped across the SE U.S.
into the FL panhandle. The trough will very slowly progress E into the Atlantic over the next few days, with the surface frontal boundary working its way south across the peninsula today and Monday before clearing the state to the south on Tuesday. Ridging aloft builds over the area around mid week with surface ridging building along the E Seaboard before a few shortwaves push E across the TN/OH Valley regions late week and over the weekend, eroding the ridge while the surface ridge weakens slightly and shifts a bit E into the Atlantic.

For today expect an increase in showers and storms with the front pushing across the area, initially across Nature Coast locations this morning before spreading into central and eventually southern areas late morning through afternoon. Given the persistent W-SW flow expect greatest concentration of convection over the interior and E FL, however a few strong to severe storms cannot be ruled out across W FL as moderate-strong instability this afternoon coupled with sufficient shear will be supportive of stronger convection ahead of the boundary. SPC has highlighted the all of the CWA under a Marginal Risk with damaging wind and hail as the primary threats, with a Slight Risk over the interior covering parts of eastern Polk and Highlands counties for an increased risk of large hail. Activity should gradually wind down this evening as the front continues south, however with moisture lingering over the area and slow progression of the trough aloft PoPs will remain in the 30-40 percent range through Mon-Tue, with highest chances over the interior during the afternoons. The remainder of the week will feature PoPs around 20 percent or less as drier conditions will be likely with ridging over the area. Temps also warm during the latter half of the week as well, into the low-mid 90s for areas away from the immediate coast, after having been in the upper 80s-lower 90s today through Tuesday.

MARINE
Issued at 515 AM EDT Sun May 19 2024

A frontal boundary slowly moving across the E Gulf today will bring scattered to numerous showers and thunderstorms across the waters. Weak high pressure gradually builds into the region by mid week with winds and seas slowly subsiding.

FIRE WEATHER
Issued at 515 AM EDT Sun May 19 2024

A front will move over the state with showers and thunderstorms for most areas today, followed by lingering rain chances on Monday and Tuesday mainly focused toward interior locations during the afternoons. High pressure and drier air will filter into the area mid to late week with warming temps.
