&& .NEAR TERM... (Through Wednesday) Issued at 300 PM EDT Tue Jun 11 2024 Showers and thunderstorms this evening will be mainly confined to south of I-10 due to the low to mid-level northwest flow pinning the seabreeze closer to the coast. On Wednesday, the flow regime weakens allowing greater penetration of the seabreeze, especially from the east coast, allowing for greater coverage of convection, most focused from the I-75 corridor of GA into the FL Big Bend; highest PoPs in the Southeast Big Bend. The main concern with any storms over the next couple of days will be gusty winds. Highs in the low to mid-90s through midweek, with lows around 70. With less northwest flow on Wednesday, the higher dew point air will creep northward into the AL and GA counties, which have had a comfortable air mass the past few days. && .SHORT TERM... (Wednesday night through Thursday night) Issued at 300 PM EDT Tue Jun 11 2024 Warmer than normal temperatures are forecast to continue through the short term. Overnight lows will largely remain in the lower 70s both nights with highs reaching into the middle 90s Thursday afternoon. There is a chance for isolated to scattered showers and thunderstorms Thursday afternoon along the sea breeze. An H5 shortwave trough traverses the region during the period. This will help temper temperatures a little from where they have been the past couple of days. This shortwave will also allow for the possibility of some isolated to scattered showers and storms along the sea breeze Thursday afternoon. The best chance for rain will be along and south of I-10 with lesser chances the farther north you go. && .LONG TERM... (Friday through Monday) Issued at 300 PM EDT Tue Jun 11 2024 Much of the period will feature well above normal temperatures. In fact, a couple of the afternoons this weekend, especially Saturday, could experience widespread triple digit heat. Overnight lows will remain quite mild with middle to upper 70s expected. Rain chances increase some along the sea breeze Sunday into early next week. Friday will see a 591dm H5 ridge trudge across the southern third of the country and set up shop overhead by Saturday. This will crank up the heat again as much of the region sees temperatures flirt with the 100 degree mark Friday afternoon and possibly exceed it Saturday afternoon. Guidance then diverges a bit Sunday and beyond as the GFS attempts to work more moisture into the region while the EURO keeps things drier, and therefore hotter. Given the recent trends the past couple of days, decided to trend a bit drier and hotter for the early part of next week. && .AVIATION... (00Z TAFS) Issued at 810 PM EDT Tue Jun 11 2024 VFR conditions are expected to prevail throughout the TAF period. There is some indication that patchy fog may impact VLD during the overnight period, but confidence was low and thus not included in the TAF. Otherwise, showers and storms may pop up across the TLH/VLD region tomorrow afternoon, possibly inducing some MVFR conditions should any storm move over a terminal. && .MARINE... Issued at 300 PM EDT Tue Jun 11 2024 Mostly favorable marine conditions are anticipated through the work week. Surface high pressure across the Mid-Atlantic will keep easterly to southeasterly winds in the forecast through the week with a slight increase this weekend due to an area of low pressure attempting to develop in the southern Gulf of Mexico. This enhanced pressure gradient may lead to cautionary, maybe even advisory, conditions this weekend into early next week. && .FIRE WEATHER... Issued at 300 PM EDT Tue Jun 11 2024 Thunderstorm chances will increase each day through Thursday, especially in the FL counties, with a drying trend Friday. Outside of this activity, especially the AL and GA counties, Minimum afternoon RH values dip into the mid-30s to mid-40s Wednesday and Thursday, with more widespread 30s Friday. Pockets of high dispersion are possible Thursday afternoon, with the potential for widespread high dispersion Friday. && .HYDROLOGY... Issued at 300 PM EDT Tue Jun 11 2024 Isolated to scattered showers and storms are possible along the sea breeze the next several afternoons. Areas underneath these storm could experience localized flooding due to intense instantaneous rainfall rates. However, widespread rainfall amounts will be low. Looking into next week, ensembles have continued to dry things out as an area of high pressure takes over across much of the southeast. This would keep the swath of heavier rain well to the south and west of the region. That said, we`ll continue to monitor where the deep tropical moisture goes later this weekend into next week. && .SPOTTER INFORMATION STATEMENT... Spotter activation is not requested.
