Area Forecast Discussion National Weather Service Tallahassee FL 327 AM EDT Thu Jun 27 2024 ...New NEAR TERM, SHORT TERM, LONG TERM, AVIATION, MARINE, FIRE WEATHER, HYDROLOGY... .NEAR TERM... (Today and tonight) Issued at 319 AM EDT Thu Jun 27 2024 Finally, a break in the heat, but it comes with a higher chance for showers and thunderstorms. In fact, a few showers and storms are already getting going along the Emerald Coast early this morning. Expect showers and thunderstorms to increase near the coast this morning, then spread inland through the late morning and afternoon as a shortwave approaches the area. Coverage will be greater than the past few days, bringing much needed rain to the area. Some of the storms today could be strong to briefly severe, mainly over the GA counties and the FL Big Bend north of I-10 where there will be a little more time to destabilize. Deep- layer shear will also increase to about 15-20 kt in this area, which is sufficient for severe storms in the summer. There is also ample instability, but not a lot of DCAPE, so storms in south Georgia and north Florida would be capable of water-loaded downbursts today. This is where SPC has outlined a Marginal Risk of severe weather (level 1 of 5) for today due to the threat of locally damaging wind gusts. Storms should move out of the area early this evening, but additional showers and storms will develop during the overnight hours near the Emerald Coast again as the shortwave still slowly moves through the area. Thanks to the added cloud cover and beneficial rain, high temperatures will be quite a bit "cooler" than recent days with upper 80s to lower 90s across the area. Heat index values will still be around 100-107 given the abundant moisture in place. Lows tonight will still be muggy as well, settling into the middle to upper 70s. && .SHORT TERM... (Friday through Saturday night) Issued at 319 AM EDT Thu Jun 27 2024 An upper level short wave trough and an associated surface feature will enhance convective coverage on Friday. As these features weaken or dissipate, PoPs will decrease a bit, but good coverage is still expected. With WMSI expected to be lower today than on Wednesday, the threat for severe downbursts is lower. As for temps, the convective coverage and associated cloud cover should keep max temps close to seasonal averages on Friday. Nevertheless, some inland locations in Florida could flirt with heat advisory criteria with heat indices around 108 degrees. && .LONG TERM... (Sunday through Wednesday) Issued at 319 AM EDT Thu Jun 27 2024 The upper ridge will retrograde westward during this period putting the area in a northwest flow regime. This will help to drive another frontal boundary into the area by early next work week, increasing PoPs once again. Heat indices look to reach advisory levels from U.S. 84 in South GA south across parts of the FL Big Bend on Sunday with the hottest day appearing to be Monday when an advisory may be needed for most of our FL counties. Convective coverage will drop back to seasonal levels for the mid to late part of next week allowing actual temperatures to rise back into the upper 90s for many areas. We can't rule out a few spots reaching 100. && .AVIATION... (06Z TAFS) Issued at 319 AM EDT Thu Jun 27 2024 VFR conditions are largely expected the next 6 hours or so at all terminals. However, some patchy fog is possible near TLH and VLD, bringing possible IFR/LIFR cigs and/or MVFR vsbys. Additionally, TSRA will begin developing near ECP by 11z, then developing further and spreading northeastward across all terminals between 13-17z. MVFR cigs/vsbys are possible in the storms. TSRA will begin exiting around 20-23z, with VFR conditions resuming thereafter. There's some possibility that TSRA will redevelop near ECP toward the end of the TAF period, but confidence is too low for inclusion in this forecast. && .MARINE... Issued at 319 AM EDT Thu Jun 27 2024 The rip current risk looks to remain high today and Friday for our southwest facing beaches, and this elevated risk could persist through the weekend, once again. Outside the surf zone, moderate west to southwest winds will persist with some weakening in wind speeds expected by the weekend and into early next week. && .FIRE WEATHER... Issued at 319 AM EDT Thu Jun 27 2024 South to southwest transport winds around 10-15 mph combined with increasingly high dispersions each day will result in spreading pockets of high dispersions each day. Showers and thunderstorms will be likely starting near the coast this morning, then spreading inland in the afternoon and evening. Some of the storms today could be strong to briefly severe with strong gusty winds being the primary threat. We'll repeat the high rain chances Friday and Saturday. && .HYDROLOGY... Issued at 319 AM EDT Thu Jun 27 2024 There are no flooding concerns at this time outside of localized nuisance flooding caused by slow-moving storms each afternoon. && .SPOTTER INFORMATION STATEMENT... Spotter activation is not requested.
