911 FXUS62 KTAE 201016 AFDTAE Area Forecast Discussion National Weather Service Tallahassee FL 616 AM EDT Sun Jul 20 2025 ...New AVIATION... .NEAR TERM... (Today and tonight) Issued at 104 AM EDT Sun Jul 20 2025 The mid-level high slides overhead today with surface high pressure very near our area. This will result in what will likely be the hottest day in terms of air temperatures of this stretch. Highs will be in the mid to upper 90s. A few spots in the FL Big Bend and south central GA may reach 100. With the mid level and surface high nearby, there will be good opportunity for moisture to mix out. So, it may not be oppressively humid, but still dangerously hot regardless. Given the continued heat, have issued another Heat Advisory for nearly all of our FL Counties and along and east of the Flint River in Georgia for heat index values of 108-112. There is some uncertainty in this though. If the CAMs that show more aggressive mixing verify, then we may not see widespread areas reach heat index values of 108. Regardless, this level of heat is still dangerous, and everyone should continue to take necessary heat precautions. Stay hydrated, take frequent breaks in the A/C or shade, wear light clothing, and check on the elderly, kids, and pets. There also won`t be much relief during the overnight hours with lows in the mid 70s to near 80 tonight. && .SHORT TERM... (Monday through Tuesday night) Issued at 159 AM EDT Sun Jul 20 2025 Hot and muggy conditions are likely to continue at the beginning of the upcoming week as the upper level ridge to our west continues to influence the pattern. Heat indices are likely to remain around advisory levels on Monday and again on Tuesday, mostly due to the more delayed onset of showers and storms thanks to the upper level ridge and drier mid-level air working into the region. By Tuesday the ridge begins to break down slowly as a weak trough begins to drop down from the northeast. Much of the guidance retains another round hot temperatures like Monday, but convective activity will likely be greater and the potential for a more active afternoon does raise some questions if locations will hit heat advisory levels before storms fire off and begin cooling things back down. && .LONG TERM... (Wednesday through Saturday) Issued at 159 AM EDT Sun Jul 20 2025 Main forecast questions for the middle to latter part of the upcoming week revolve around another broad area of low pressure moving east to west across the state or northern Gulf. Similar to last week, this broad area of low pressure could develop along the southern end of a decaying frontal system. With rounds of disorganized shower and storms coverage each afternoon, some weak development can`t be ruled out as this feature drifts west into the northern Gulf. Regardless of any development, a return to more widespread shower and thunderstorm chances is likely, especially on Wednesday and Thursday of this upcoming week. This will cool conditions back down in the lower 90s and likely give the area a reprieve from the recent hot conditions. && .AVIATION... (12Z TAFS) Issued at 613 AM EDT Sun Jul 20 2025 VFR conditions will prevail over the next 24 hours. Some SCT to occasionally BKN MVFR cigs have been impacting ECP, and this will remain possible during the next couple hours. Additionally, a bit of patchy fog has developed around TLH, which may cause a brief dip to MVFR vsbys. Isolated SHRA/TSRA will develop this afternoon near the terminals (mainly ECP and TLH), but chances are too low to include in the TAFs. && .MARINE... Issued at 159 AM EDT Sun Jul 20 2025 Favorable boating conditions will continue into the start of next week. Southerly winds will become westerly overnight, at about 5-10 kts. 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 159 AM EDT Sun Jul 20 2025 High pressure slides across our area and to the west over the next few days. Only a few stray showers or storms are expected today, but more typical coverage of showers and storms is expected Monday and Tuesday as moisture begins to increase. With high mixing heights and generally west to northwest transport winds around 10-15 mph, dispersions will be high away from the coast through Tuesday. Otherwise, dangerous heat will continue for the next several days with highs in the upper 90s and heat index values of 105-112. && .HYDROLOGY... Issued at 159 AM EDT Sun Jul 20 2025 Drier conditions are expected into Monday but a wetter pattern likely begins to develop for the rest of the upcoming week on Tuesday as a weak area of low pressure drifts east to west across the northern Gulf. Widespread rain totals of 2 to 4 inches are possible across Florida with lesser amounts across Alabama and Georgia. Typical of our summertime storms, widespread flooding rains are not expected but localized heavy downpours could produce brief localized flooding, especially in any locations which have been wetter than normal this summer. && .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...
