Area forecast discussion, Jul 19, 2:33 PM CDT, 24 minutes before
Area Forecast Discussion National Weather Service Tallahassee FL 333 PM EDT Fri Jul 19 2019 .NEAR TERM [Through Tonight]... Shower and thunderstorms will continue to persist several hours after sunset over land, with the main threats being gusty winds and heavy rainfall. With PWATs approaching 2" across the region and weak steering flow in place, localized flooding will be an issue this afternoon as storms yield rainfall rates of up to 2"/hour at times. As storms wane inland overnight, convection offshore will pick up. Mostly cloudy skies overnight will preclude widespread fog, but patchy fog will be possible in areas where soils are saturated from rains this afternoon. Temperatures overnight will cool into the low to mid 70s. .SHORT TERM [Saturday Through Sunday Night]... The weak upper level low that brought widespread showers and thunderstorms will slowly traverse west across the Gulf coast through the weekend. In its wake a slightly drier airmass moving in from the southeast will keep thunderstorm coverage a little lower through the weekend. Expect shower coverage to be greatest west of Tallahassee/Albany on Saturday with coverage further reducing on Sunday where only 30 to 40 POPs are anticipated across the forecast area and most focused along the seabreeze. Temperatures will remain in the lower 90s with a potential cool down (albeit slight) on the horizon for next week as a weak front pushes southeast. .LONG TERM [Monday Through Friday]... The region will be situated between two upper level ridges on Monday with isolated to scattered showers expected in the afternoon. Through next week, the upper level ridge to our east will begin to break down as a large central US trough amplifies and digs southeast. This trough will bring a weak cold front into the region on Tuesday but indications are that it will stall somewhere near the coast or over inland portions of southeast AL or southern GA. Depending where it stalls, expect locations along and ahead of the front to remain in a much wetter pattern than normal. This front should stick around through the middle of next week and possibly towards the end of the week, though its length of stay will depend how quickly the Bermuda high rebuilds in from the east. With the increased cloud cover with the front, temperatures will trend cooler and fall into the upper 80s and near 90. && .AVIATION... [Through 18Z Saturday] Scattered SHRA/TSRA continue across parts of the tri-state region at this hour, with the most likely terminal to see impacts in the next few hours being VLD. Will have to monitor DHN and TLH for potential storms moving in later this afternoon. Reductions in CIGS/vsby as well as gusty and erratic winds will be possible with these storms. Backed off on fog overnight from the inherited TAFs, but patchy fog will be possible, especially near terminals that see a lot of rainfall this afternoon. && .MARINE... Winds will remain on the lighter side through the next week and generally at or below 10 knots through the period. Seas will also remain on the lower side and only around 1 to 3 feet through the next 7 days. Shower and thunderstorm chances will be greatest in the overnight and morning hours with lesser coverage expected in the afternoon. && .FIRE WEATHER... KBDI values have been creeping up, but there's a wet pattern on tap for the weekend. 20 ft winds will be light and RH values will be mostly above 50%, so no red flag conditions are forecast. && .HYDROLOGY... Local rivers are below action stage. Rainfall chances return to normal over the weekend, but looking ahead into next week a cold front will likely stall somewhere over the southeast bringing the possibility for well above normal rainfall chances beginning in the middle of next week. && .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...
