Area forecast discussion, Apr 25, 9:39 PM EDT, 35 minutes before
Area Forecast Discussion National Weather Service Tallahassee FL 939 PM EDT Thu Apr 25 2019 .NEAR TERM [Through Tonight]... The cold front is currently (8:30 PM EDT) located over Central MS and New Orleans. Strong to severe thunderstorms will move through the region this evening and overnight. Instability is fairly low around 500 to 1000 J/KG mainly in the FL Panhandle. Deep layer shear is high around 50 knots. These storms may intensify as a shortwave trough moves through around midnight. A tornado watch is in effect until 1 AM EDT for most of the FL Panhandle. Damaging winds will be the primary threat but a few isolated tornadoes are also possible. .SHORT TERM [Friday Night Through Saturday Night]... Upper trough responsible for pushing the cold front through the region will lift out quickly to the northeast late Friday. Largely zonal flow will take its place through Saturday with dry conditions expected. Airmass behind the front is not a whole lot cooler than in front, so temperatures will remain mild on Saturday. Expect to start the day in the lower to mid 50s before rising to the lower to mid 80s in the afternoon. .LONG TERM [Sunday Through Thursday]... Upper ridge is forecast to build over the Southeastern states by early next week. This will keep the weather dry and warm. May see some 90 degree high temperatures creep into the area by Monday and Tuesday. .AVIATION... [Through 00Z Saturday] A line of strong to severe storms will move through the region tonight. MVFR CIGs are likely overnight and in the morning hours. Brief periods of IFR conditions are possible. VFR conditions will return in the late morning hours. Rain will be moving out of the region by sunrise. .MARINE... Winds will increase to Exercise Caution levels overnight as a front crosses the coastal waters. Winds could locally be much higher in and near the showers and thunderstorms. Conditions will improve into Saturday, with light winds and low seas expected through early next week. .FIRE WEATHER... Rain is expected tonight. Much drier air will move into the region by Saturday. Relative humidity values will be in the 40 percent range tomorrow and in the 20-35 percent range on Saturday. Red Flag conditions are not expected since winds will be light Saturday. High dispersions over 75 are expected tomorrow. .HYDROLOGY... The Apalachicola River near Blountstown continues to slowly fall. Elsewhere, rivers and streams are generally steady or falling. Rainfall amounts tonight into Friday will range from less than half an inch in the north to around 1.5 inches along the coast. These amounts may cause some temporary rises in the smaller basins, but significant rises are not expected. .SPOTTER INFORMATION STATEMENT... Spotter activation is requested. Spotters should safely report significant weather conditions and/or damage by calling the office or tweeting us @NWSTallahassee. && .PRELIMINARY POINT TEMPS/POPS...
