041 FXUS62 KTAE 220051 AFDTAE Area Forecast Discussion National Weather Service Tallahassee FL 851 PM EDT Mon Jul 21 2025 ...New UPDATE... .UPDATE... Issued at 848 PM EDT Mon Jul 21 2025 Only a few minor tweaks needed to the PoPs this evening to hold slight chance PoPs for the eastern zones for a few more hours, as a few showers and storms have continued to bubble up into the early evening. This activity should diminish over the next hour or two with the loss of daytime heating. && .NEAR TERM... (Through Tuesday) Issued at 211 PM EDT Mon Jul 21 2025 The mid-level ridge that has dominated our large-scale weather pattern and that is responsible for the dangerous heat of late will continue shifting west and begin to break down on Tuesday. This will position our CWA on the northeastern periphery of the ridge and allow generally north/northwesterly flow to establish. This setup introduces some uncertainty in how hot it will be able to get during the day on Tuesday. On one hand, surface temperatures will again easily climb into the upper 90s across the region. On the other hand, drier low/mid level air will filter through in response to the more northerly flow which would limit how high apparent temperatures can climb - especially in our northwestern counties. Additionally, the expectation of afternoon showers and thunderstorms adds more complexity to the upper limits of heat tomorrow. Heat advisories will again be needed for much of the CWA. Remember to stay hydrated, take frequent breaks in the A/C or shade, wear light clothing, and check on the elderly, kids, pets, and other vulnerable people. In regards to convection, PoPs are expected to climb on Tuesday - mostly in response to the ridge exiting and degrading, reducing large scale subsidence. Drier air and thus increased DCAPE values resulting from northerly flow introduces some concerns for gusty winds in isolated storms. In general, storms will move north-south, with the greatest coverage in our eastern counties farthest removed from the ridge and where moisture will be greatest. The seabreeze`s inland progression will likely be limited on Tuesday as northerly flow helps pin it closer to the coast. Still, it is an area of focused convergence to watch for enhanced thunderstorm development. For now, the Storm Prediction Center has placed our northeastern counties where the greatest favorability in a wind-driven Marginal (level 1 of 5) risk for severe weather on Tuesday. && .SHORT AND LONG TERM... (Tuesday night through Sunday) Issued at 211 PM EDT Mon Jul 21 2025 Ridging begins to break down Wednesday as an area of low pressure (Formerly known as 93L) once again makes it`s way through from the east, having come full circle around the high pressure that`s been sitting over us as of late. Afternoon high temperatures will be notably cooler, expected to be in the upper 80s to lower 90s through Friday. Moisture will also get another notable influx, pushing PWAT values into the 2 to 2.5 inch range. This will lead to some rather efficient rain makers for the last half of the work week, having the potential to cause some flooding concerns under slower moving or training storms. Temperatures will then begin to increase this weekend, as high pressure once again builds into the area, decreasing rain chances from east to west as the low exits. The potential in place to bring near heat advisory levels back to the area late in the period, a similar pattern in place to the prior weekend. && .AVIATION... (00Z TAFS) Issued at 739 PM EDT Mon Jul 21 2025 VFR conditions expected to prevail through the overnight hours at all terminals as evening convection wanes. Convective coverage expected to be more widespread on Tuesday afternoon, especially for the eastern terminals. KABY, KVLD, and KTLH mostly likely to be impacted, with activity likely to begin around 18z. && .MARINE... Issued at 211 PM EDT Mon Jul 21 2025 Favorable boating conditions will continue. With the afternoon seabreezes, winds may gust 15-20 kts in our nearshore waters through the weekend into next week. Seas are expected to be tranquil at 1-2 feet through the week. Widespread showers and thunderstorms return by Tuesday, and especially by Wednesday/Thursday as a weak area of low pressure potentially moves into the Gulf. Some development and an increase in winds/seas can`t be ruled out at this time. && .FIRE WEATHER... Issued at 211 PM EDT Mon Jul 21 2025 Overall, fire weather concerns remain low the next several days. Dangerous heat will continue through Tuesday with highs in the upper 90s and heat index values of 105-112. Westerly transport winds today will turn more northerly during the day Tuesday along with high dispersions. High pressure moving west of the area will allow moisture to stream back into the region. Rain chances increase some Tuesday before increasing even more Wednesday and Thursday as ample moisture moves over the region. && .HYDROLOGY... Issued at 211 PM EDT Mon Jul 21 2025 Rain chances continue to improve through the week, and the WPC includes our region in Marginal (level 1 of 4) risks through the week. Widespread showers and thunderstorms return by Tuesday and especially by Wednesday/Thursday as a weak area of low pressure potentially moves into the Gulf. Overall, about 2-4 inches of rain is expected through the forecast period. While widespread flooding rain is not expected, the high moisture content of the airmass and any training of storms could yield a quick 3 to 5 inches of rainfall for isolated locations. This could cause brief flooding in poor drainage areas, low-lying roads, or across urban environments. && .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...
