088 FXUS62 KTAE 121901 AFDTAE Area Forecast Discussion National Weather Service Tallahassee FL 301 PM EDT Thu Jun 12 2025 ...New NEAR TERM, SHORT TERM, LONG TERM, MARINE, FIRE WEATHER, HYDROLOGY... .NEAR TERM AND SHORT TERM... (Through Saturday Night) Issued at 302 PM EDT Thu Jun 12 2025 Satellite-derived PW imagery shows an area of very moist air from the Florida Keys into the Southeast Gulf and off the SW FL coast, characterized by PW values of 2-2.2 inches. The 12z Key West balloon sounding confirmed this by observing a 2.1-inch PW. In the southerly flow rounding the west end of the Atlantic subtropical ridge, this slug of moisture will spread northward across our area on Friday, Friday night, and Saturday, before departing on Saturday evening. Large-scale lift could be slightly enhanced as the upper trough over Texas slowly lifts northeast across the Mid-South and Mid-Mississippi Valley regions. Ultimately, the pool of rich moisture will enhance convective coverage through Saturday. Such a richly moist air mass can contribute to torrential rainfall rates beneath the core of thunderstorms. Ensemble-based guidance such as the HREF does not point to abnormally high probabilities of rainfall exceeding flash flood guidance, but any training or backbuilding cells in this environment could bring a quick and localized 4-6 inches of rain, which would be enough for isolated flash flooding. && .LONG TERM... (Sunday through Thursday) Issued at 302 PM EDT Thu Jun 12 2025 On Sunday, we will lose any large-scale lift from the Mid-South shortwave, as it deamplifies and exits east through the Ohio Valley. The air mass will still be very moist as high Pwats and mid-level moisture linger near the back edge of the incoming slug. From Monday through Wednesday, the subtropical ridge axis will try to sharpen near our latitude and strengthen along its western periphery closer to Florida. Around the southern periphery of the climatological and dominant ridge, dry mid-level air that is currently north and northeast of Puerto Rico will start to filter in across the region. By Wednesday, PW values will only be in the 1.6-1.7 inch range. This is still enough to support deep, moist convection, but larger-scale subsidence under the ridge will keep convection confined to more favorable seabreeze front locations. With fewer thunderstorms to cool the atmosphere and strengthening high pressure aloft, temperatures will edge upward next week. By next Thursday, inland high temperatures in the mid 90s will be common. && .AVIATION... (18Z TAFS) Issued at 1158 AM EDT Thu Jun 12 2025 Summertime pattern across the terminals with the potential for TSRA until around 00Z. This may lead to brief MVFR restrictions with a low probability of IFR, especially DHN and VLD as shown in TEMPO groups. Northward extent of TSRA a lower probability at ABY, and mainly VCTS at ECP and TLH as the seabreeze lifts north, although a quick amendment may be needed at the aforementioned sites if a TSRA moves over the terminals. On Friday, stronger low to mid-level southerly flow should initiate TSRA earlier in the vicinity of ECP and TLH with a PROB30 group for TSRA; uncertainty in timing, but have started with 14Z for now at both terminals. && .MARINE... Issued at 302 PM EDT Thu Jun 12 2025 Gentle to sometimes moderate southeast breezes will prevail through Saturday, while the subtropical Atlantic ridge axis resides north of the waters. The ridge will migrate south across the waters on Sunday, then persist across the Florida Peninsula and the eastern Gulf on Monday and Tuesday. Showers and thunderstorms will be the main threats to mariners, including strong wind gusts, lightning and waterspouts. && .FIRE WEATHER... Issued at 302 PM EDT Thu Jun 12 2025 A seasonably hot, moist and unstable air mass will be in place through the middle of next week, with daily chances of showers and thunderstorms. So the main fire weather concerns will be thundertorm-related, specifically lightning along with erratic and gusty winds near storms. && .HYDROLOGY... Issued at 302 PM EDT Thu Jun 12 2025 Hydrology concerns over the next 7 days will consist of localized nuisance runoff issues and isolated flash flooding. A typical pattern of summer thunderstorms will persist for the next week. Beneath the core of stronger thunderstorms, intense rainfall rates have potential for localized runoff issues, especially in urban and poor drainage areas. With torrential rain rates, storms that linger over the same area for too long would bring isolated flash flooding. Lastly, the air mass will be moistest on Friday and Saturday, so rain rates and flash flood potential will peak then. && .SPOTTER INFORMATION STATEMENT... Spotter activation is not requested.
