395 FXUS62 KTAE 272315 AFDTAE Area Forecast Discussion National Weather Service Tallahassee FL 715 PM EDT Thu Mar 27 2025 ...New AVIATION... .NEAR TERM... (Through Friday) Issued at 251 PM EDT Thu Mar 27 2025 High pressure over the Appalachians will slide into the western Atlantic tonight into Friday. Aloft, a weak shortwave will pivot the western periphery of a ridge, which will only bring more cloud cover tonight. Winds will become more southeasterly tonight then southerly Friday. Lows will be 50s across most of the area tonight. The cloud cover will break up some during the day Friday. Moisture will be on the increase as well with the return flow off the Gulf, but not enough to squeeze out any rain. Temperatures will remain above average with highs in the lower to middle 80s. && .SHORT TERM... (Friday night through Saturday night) Issued at 251 PM EDT Thu Mar 27 2025 Southern stream upper level trough moves east across the Central Gulf coast Friday night into Saturday while at the surface, low- level south and southeasterly flow becomes better established as surface high pressure across the western Atlantic retreats eastwards. Warm conditions from Friday should continue into Saturday and with good mixing expect breezy conditions across the area with sustained winds around 10 to 15 mph and occasional gusts of 20 to 25 mph. As the upper level trough approaches in the evening it will gradually be weakening but ongoing showers and storms to our west combined the increasing moisture from southerly flow could allow additional development overnight Saturday, or a maintenance of the ongoing activity, but there is still considerable uncertainty. Some of the drier guidance is slower and weaker with the wave like the Euro/Canadian solutions while the GFS is stronger and quicker and keeps more widespread coverage of showers and a few rumbles of thunder going into early Sunday morning. && .LONG TERM... (Sunday through Wednesday) Issued at 251 PM EDT Thu Mar 27 2025 Regardless of the progress of the Saturday night`s shortwave, increasing southwesterly flow Sunday afternoon along with continued moisture advection should allow shower and thunderstorm chances to remain in play for the afternoon. Weak wind fields and a lack of any significant low-level forcing should preclude most/if-any severe threats, but an isolated strong storm can`t be ruled out and the afternoon will likely similar to a typical summer afternoon where isolated/scattered activity develops. Coverage reduces overnight Sunday into Monday morning but as a stronger upper level trough and front moves south, expect better support for severe storms Monday afternoon compared to Sunday afternoon. Storms will be ongoing to our west Monday morning and will begin to approach the region in the afternoon and evening hours. Plenty of instability will exist out ahead of these storms to maintain coverage as the front moves east, but with upper level forcing lifting out and the front gradually weakening, there is still uncertainty to how far south and east the greater severe threat will persist. For now, the whole region is in a slight risk on the current Day 5 SPC outlook, but further refinements in that outlook will come in the next few days. After the front moves through, some residual showers and storms are possible on Tuesday, especially in guidance that has a slower frontal passage like the Canadian, so left a 10 to 20% chance of rain in the forecast for that period to account for that uncertainty. && .AVIATION... (00Z TAFS) Issued at 715 PM EDT Thu Mar 27 2025 VFR conditions are expected to prevail through the TAF period. There is potential for lowered vsbys affecting the VLD terminal during the early morning hours Friday, however confidence at this time is low. Winds will become southeasterly Friday afternoon at around 10kts with the occasional gusts up to about 15-20kts. && .MARINE... Issued at 251 PM EDT Thu Mar 27 2025 A sprawling surface high pressure center will move from the coastal Carolinas to near Bermuda by the weekend. In response, winds over the northeast Gulf will clock around and become easterly late today. As is common with easterly flow, there will be fresh to possibly strong nighttime wind surges tonight and again on Friday night. Winds will become more southerly this weekend, as a cold front moves across the Southern Plains and Lower Mississippi Valley. That front will reach the waters around Monday night, preceded by a chance of showers and thunderstorms. && .FIRE WEATHER... Issued at 251 PM EDT Thu Mar 27 2025 Southeasterly transport winds will be maintaining a speed of around 10-20 mph heading into the weekend. Afternoon mixing heights will be healthy ranging from 4k ft to above 6k ft. Dispersions will be moderate to excellent throughout the districts. Expect the highest dispersions to be along the I-10 and I-75 corridors, as well as the wiregrass region in SE Alabama. The better news is that minimum relative humidity values are expected to increase to the low t mid 30s percent on Friday and into the upper 30s to low 40s on Saturday due to the moisture advection from the southerly winds. With the moisture increase, there is a slight chance for patchy fog along and east of the I-75 corridor Friday and Saturday mornings. Showers and thunderstorms return later this weekend Saturday night into Sunday, which could bring a wetting rain. && .HYDROLOGY... Issued at 251 PM EDT Thu Mar 27 2025 Flooding is not expected for the next 7 days due to rainfall amounts less than 2 inches. && .SPOTTER INFORMATION STATEMENT... Spotter activation is not requested.
