Area forecast discussion, Aug 8, 2:59 PM EDT, 3 hours 49 minutes before
Area Forecast Discussion National Weather Service Tallahassee FL 259 PM EDT Wed Aug 8 2018 .NEAR TERM [Through Tonight]... Deep layer high pressure over the Atlantic shifting west slightly will keep southwesterly flow throughout the column, and in turn PW values elevated as moisture is guided in from the gulf. Some higher Surface Based CAPE today via the 12Z TAE sounding, compared to 24 hours prior almost up 1k, along with PW values of 1.78 inches should result in a bit more coverage this evening as afternoon storms are now beginning to take hold along the coastline. Coverage will expand north and east, with the best coverage expected along a swath covering the big bend to just past the GA border and East. A few storms might linger into tonight with the majority of activity diminishing after sunset. Expect lows in the mid 70s and possibly some patchy fog just prior to sunrise. .SHORT TERM [Thursday Through Friday Night]... Upper ridge will gradually slide southward over the next two days as a weak trough slowly approaches from the northwest. With an associated decrease in subsidence from the ridge, expect to see coverage of diurnal convection increase a bit Thursday, and again on Friday. High temperatures should reach the lower 90s, near seasonal normals for August. .LONG TERM [Saturday Through Wednesday]... The subtropical ridge axis will remain to the south through the weekend, with weak disturbances in the mid-level westerly flow helping to enhance coverage of afternoon and evening thunderstorms. By early next week, a more substantial upper trough is forecast to develop over the Ohio River Valley, with a trough axis extending to the central Gulf Coast. This will place the forecast area in a favorable regime for numerous showers and thunderstorms each afternoon at least through Tuesday. && .AVIATION [Through 18Z Thursday]... SHRA/TSRA developing this afternoon and continuing into this evening before diminishings tonight. Conditions will generally be VFR outside of TSRA influence. However, Patchy fog and reduced cigs could reduce conditions to MVFR/IFR briefly before sunrise as well. Winds will be southwesterly 5 to 10 kts becoming light and variable overnight. && .MARINE... Generally light onshore flow will continue through Thursday before becoming westerly on Friday through the weekend. Winds may approach 15 knots Friday night before diminishing by Sunday for the remainder of the forecast period. && .FIRE WEATHER... In addition to moist summertime conditions, relative humidity, winds, and indices will remain below critical thresholds over the next several days. && .HYDROLOGY... Scattered showers and thunderstorms will produce brief periods of heavy rain across our area through the end of this week. However, by early next weak ample moisture and the formation of a weak front over our CWA could lead to fairly high coverage of scattered showers and thunderstorm. Minor urban flooding and localized river rises are possible in areas of slower moving storms with high rainfall rates. && .SPOTTER INFORMATION STATEMENT... Spotter activation is not requested. However, spotters are always encouraged to safely report significant weather conditions when they occur by calling the office or tweeting us @NWSTallahassee. && .PRELIMINARY POINT TEMPS/POPS...
