356 FXUS62 KTAE 180750 AFDTAE Area Forecast Discussion National Weather Service Tallahassee FL 350 AM EDT Thu Jul 18 2024 ...New NEAR TERM, SHORT TERM, LONG TERM, MARINE, FIRE WEATHER, HYDROLOGY... .NEAR TERM... (Today and tonight) Issued at 225 AM EDT Thu Jul 18 2024 Continued troughiness to the north and west will allow for shortwaves to ride over the ridge currently over the FL Peninsula and the western Atlantic. This will again lead to forcing for ascent today, and when coupled with the high moisture content (PWATs around 2 - 2.5 inches) given the established southerly flow, we`ll again have elevated chances for precip today. Showers and storms will begin this morning across the FL Panhandle and offshore waters and will then gradually move inland throughout the day. Forcing will be provided through the sea breeze and by mid-level perturbations. Ongoing showers and thunderstorms to our west are a few hours ahead of when high-res guidance had them initiating. We`ll have to see if this early start and it`s associated cloud cover leads to reduced rain chances throughout the day for inland areas. Nonetheless, activity is expected to be diurnally forced, thus winding down around sunset. Expect daytime highs generally in the low to mid 90s with overnight lows generally in the mid to upper 70s. && .SHORT TERM... (Friday through Saturday night) Issued at 225 AM EDT Thu Jul 18 2024 Broad upper level troughing will extend from southeastern Canada southwestward into the western Gulf and will serve as the weakness between an upper high over the four corners and the Bermuda ridge to our east. To begin Friday, a weak frontal boundary will stretch across our western zones then move back north during the day while continuing to weaken. Will want to keep an eye on the location of the front Friday afternoon for heavier rain locations which may favor southeast Alabama. Otherwise, PWATs continue in the 1.8-2.5 range with widespread 60-80% rain chances each day. Localized pockets of flooding could occur in areas of slow moving or training of storms. Highs both days will be in the low to mid 90s. && .LONG TERM... (Sunday through Wednesday) Issued at 225 AM EDT Thu Jul 18 2024 Troughing in the southeast US weakens and pushes back northwestward as the Atlantic ridge builds back westward into the area beginning Sunday. Rain chances are slightly less Sunday and Monday but not by much. There is some low to mid level drier air on cross sections through our area which may lessen coverage and thus slightly lower rain chances. A tropical wave and increase in moisture arrives Tuesday and Wednesday with a return to a more widespread coverage of convection. && .AVIATION... (06Z TAFS) Issued at 136 AM EDT Thu Jul 18 2024 VFR conditions are expected throughout the TAF period. Showers and thunderstorms, beginning around sunrise this morning and continuing into the afternoon, could lead to brief periods of MVFR to IFR conditions if they occur directly over a terminal. Otherwise, expect activity to begin winding down around sunset with VFR conditions prevailing into the overnight period. && .MARINE... Issued at 225 AM EDT Thu Jul 18 2024 Favorable marine conditions will continue through early next week. Light to occasionally moderate south to southwesterly winds are expected thru this weekend before turning more southeasterly early next week. Seas will generally run less than 2 feet. Showers and thunderstorms are expected to develop during the early morning hours each day. Suddenly higher winds, frequent lightning, waterspouts, and increased seas are possible in the vicinity of any storms. && .FIRE WEATHER... Issued at 225 AM EDT Thu Jul 18 2024 Morning and afternoon showers and thunderstorms are once again on tap for today and tomorrow. Other than erratic directional wind changes around thunderstorms, there are currently no fire weather concerns. Fair to good dispersions are expected. && .HYDROLOGY... Issued at 225 AM EDT Thu Jul 18 2024 Unsettled weather will continue over the next week with generally 1.5-3 inches of rainfall in our area with locally higher amounts, with the heavier side of that range favoring our western counties. Over the next two days, WPC has a marginal risk (Level 1 of 4) for excessive rainfall for areas north and west of the Florida Big Bend. Localized nuisance flooding in poor drainage areas will be possible where storms are slow moving or train over an area for an extended period of time. && .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...
