711 FXUS62 KTAE 250824 AFDTAE Area Forecast Discussion National Weather Service Tallahassee FL 324 AM EST Mon Nov 25 2024 ...New NEAR TERM, SHORT TERM, LONG TERM, AVIATION, MARINE, FIRE WEATHER, HYDROLOGY... .NEAR TERM... (Today and tonight) Issued at 322 AM EST Mon Nov 25 2024 For today, we`ll start off the morning with some patchy fog across the area which should dissipate by mid-morning. Otherwise, a very subtle shortwave will move across southern Alabama into southwest Georgia with a very weak surface trough / convergence zone developing generally along and west of US 231. There may be just enough low-level moisture and convergence to squeeze out a few spotty light showers through the day over the western Panhandle into southeast Alabama. Rain chances are low at around 20 percent for these areas. Elsewhere, dry conditions are expected with highs in the mid to upper 70s. For tonight, low rain chances at around 20 percent continue for the western portions of the area. Another round of patchy fog is expected with overnight lows ranging from the upper 40s across the southeast big bend to the mid 60s along the coastal panhandle where light southerly flow will be present. && .SHORT TERM... (Tuesday through Wednesday night) Issued at 322 AM EST Mon Nov 25 2024 A weak cold front dropping into the Tri-State area on Tuesday brings increasing clouds with a slight chance (less than 25%) of showers. Any precipitation should be light and oriented into broken SW-NE bands that could linger into Wednesday morning. The front then stalls just to our south before beginning to lift north as a warm front ahead of a stronger upstream system to conclude the short-term period. Expect unseasonably warm and humid conditions with widespread mid/upper 70s for highs and overnight lows mainly in the 50s. These values are several degrees above normal for late November. Given the increased low-level moisture amidst light/calm winds, patchy to areas of fog are forecast along the I-10 corridor into SW GA during the early morning hrs where local CAMs show the strongest signals. && .LONG TERM... (Thursday through Sunday) Issued at 322 AM EST Mon Nov 25 2024 A series of shortwaves rotating through the base of a mean Eastern US upper trough defines our weather during the long-term period. For Thanksgiving, the lead shortwave dives SE from the Plains and induces surface cyclogenesis across the TN Valley. This system pushes a stronger cold front into the region than its aforementioned predecessor. As a result, expect greater PoP compared to Tuesday with a slight chance of thunder. We are currently looking at 25-50% along/NW of a Valdosta-to-Panama City line around dinner time with the best potential across the Wiregrass. Despite sufficient shear, prospects on severe weather are low at this time given meager instability. The axis of highest precipitation steadily shifts eastward that night with full FroPa by Friday morning. Chilly conditions then arrive to conclude the period. Widespread highs in the 60s are forecast Friday-Saturday (isolated upper 50s), then struggle to eclipse 60 degrees on Sunday. Expect a return to overnight lows predominantly in the 30s via cold-air advection this weekend. Isolated light freezes are possible across the Wiregrass. Regardless, a north wind of around 5 mph will drop feels-like temperatures to near or below freezing. These values re-introduce cold weather sheltering concerns to vulnerable populations. Greater (air temperature) freeze potential appears to hold off until Monday morning. && .AVIATION... (06Z TAFS) Issued at 322 AM EST Mon Nov 25 2024 Patchy fog is expected to develop across the region early this morning with pockets of visibilities in the LIFR range at times. Patchy fog is expected to dissipate in the 13z-15z time range with VFR prevailing thereafter. There is around a 20 percent chance of light showers around ECP and DHN this afternoon with no significant restrictions expected. && .MARINE... Issued at 322 AM EST Mon Nov 25 2024 The West Tampa Buoy (42036) was reporting light SSE winds and seas less than 1 ft overnight. From CWF Synopsis...Surface high pressure gives way to weak front on Tuesday which will be accompanied a westerly wind and the potential for isolated showers. This front then stagnates across the waters on Wednesday before lifting north as a warm front by Thanksgiving. Better chances for showers and thunderstorms are forecast in response to an attendant system sweeping east through the Tennessee Valley. Cautionary conditions then arrive to close out the week with the arrival of post-frontal northerly breezes. && .FIRE WEATHER... Issued at 322 AM EST Mon Nov 25 2024 Dispersions will be on the low side this afternoon across the southeast big bend and portions of south central Georgia with light transport winds and modest mixing heights. Otherwise, fire weather concerns will remain low over the next few days with light winds and relative humidity values remaining above critical levels. A few light showers are possible in the Florida Panhandle and southeast Alabama today, then along the I-10 corridor Tuesday, but wetting rains are not expected. && .HYDROLOGY... Issued at 322 AM EST Mon Nov 25 2024 After a stretch of dry weather, rain chances return to the forecast from a couple of fronts this week - one on Tuesday (weak) and another on Thanksgiving (stronger). However, current forecast amounts do not warrant any flooding concerns at this time given the expected progressive nature of these systems. The placement of heaviest rainfall may have future riverine implications via downstream flows from Central GA/AL. We dry out once again as the week draws to a close. && .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...
