653 FXUS62 KTAE 170944 AFDTAE Area Forecast Discussion National Weather Service Tallahassee FL 544 AM EDT Thu Jul 17 2025 ...New AVIATION... .NEAR TERM... (Today and tonight) Issued at 150 AM EDT Thu Jul 17 2025 Weak low pressure across the north-central Gulf coast will continue to move away from the area today. However, southerly flow will continue to keep moisture elevated with precipitable water values over 2 inches, especially across the western half of the area. Thus, scattered to numerous showers and thunderstorms are expected to develop today with the greatest coverage across the western half of the area. Locally heavy downpours and frequent lightning will be the main threats. The onshore flow will also contribute to a high risk of rip currents at the beaches today. High temperatures will generally range from around 90 across the western half of the area to the mid 90s across the eastern portions of the area. Overnight lows will remain muggy in the low to mid 70s, except upper 70s along the coast. && .SHORT TERM AND LONG TERM... (Friday through Wednesday) Issued at 150 AM EDT Thu Jul 17 2025 The low pressure area continues into southern Arkansas Friday with southeasterly flow remaining across the area, at least for 1 more day. PWATs continue at 2"+ inches leading to good coverage of showers and storms through the area with highs in the mid 90s. The subtropical ridge will build westward across the Florida peninsula and southeast US Saturday then into the southern Plains Sunday. Moisture decreases with PWATs falling to around 1.7-1.8 inches as winds turn to more southwesterly and westerly. Afternoon rain chances slide to chance category (40-50%) favoring I10 and south to 20-30% into southwest Georgia. As the dome of high pressure sits overhead, less cloud cover and decreasing moisture, highs this weekend will push the upper 90s to near 100 degrees which appears to extend into Monday as well. Heat advisories are possible this weekend into early next week, depending on how well mixing takes place each day. A shortwave trough riding over the ridge will act to break the western Atlantic ridge beginning late Monday which may allow an increase in moisture from the north. Rain chances will jump back up beginning Tuesday which will allow a reprieve from the near 100 degree highs from the weekend with highs back into the mid 90s for the middle part of next week. && .AVIATION... (12Z TAFS) Issued at 543 AM EDT Thu Jul 17 2025 Showers and thunderstorms are expected to develop this morning offshore and move northward and affect ECP through the mid to late morning hours. Elsewhere, scattered showers and thunderstorms will gradually increase in coverage through the morning and into the afternoon hours with TLH and DHN also likely to see activity. Mainly VFR conditions are expected outside of thunderstorms, although some MVFR ceilings are possible this morning, particularly around ECP. && .MARINE... Issued at 150 AM EDT Thu Jul 17 2025 A late evening ASCAT pass showed southeast winds of 15-16 knots across the northeast Gulf waters. Expect a slight uptick in winds currently through tonight with cautionary conditions slowly winding down in waters east of Apalachicola early this afternoon and later tonight in waters west of Apalachicola. Winds turn to southwesterly beginning this weekend as deep layer high pressure sets up through the southeast US. Marine conditions will be favorable after tonight, beginning Friday through early next week. && .FIRE WEATHER... Issued at 150 AM EDT Thu Jul 17 2025 A seasonably moist and unstable air mass will continue for the foreseeable future. Areas of high dispersion are expected this afternoon across portions of southwest and south-central Georgia due to enhanced southerly transport winds. A warming trend will get underway on Friday, with above average temperatures starting Saturday. && .HYDROLOGY... Issued at 150 AM EDT Thu Jul 17 2025 Isolated flash flooding will be a concern through Friday, mainly over our FL counties. Over the next 24-30 hours, 1 to 3 inches of rain will be common, with the I-75 corridor in Georgia being the driest. If convection trains onto the coast, then expect a quick 4 to 6 inches of rain somewhere in our FL counties. These higher amounts would bring isolated flash flooding. Lesser amounts could still bring less serious nuisance flooding and ponding on roadways. Thunderstorm coverage will decrease over the weekend, then build during the first half of next week. Most any summer thunderstorm is capable of intense rainfall rates that can lead to short-lived nuisance flooding. && .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...
