(00Z TAFS) Issued at 609 PM CDT Thu Aug 8 2024 VFR conditions are expected through Friday.

NEAR TERM... (Now through Friday) Issued at 407 PM CDT Thu Aug 8 2024 A northwesterly to northerly flow pattern aloft will persist across our area through Friday as the local forecast area remains positioned between a deepening upper troughing to our east (which will finally lift remnants of Tropical Storm Debby up the east coast) and upper level ridging centered over Texas that will be gradually building more into the Lower Mississippi Valley region. A weak surface front/trough that pushed into the southeast CONUS today will push a little further south into our area on Friday as remnants of Debby lift up the east coast, but stalls over our area or just offshore on Friday. This too will help maintain a dry, mostly northwesterly low level flow over the area as well. Overall, PWATS generally remain in the 1.75 inch range across the region. With the surface boundary and associated moisture, there could be an isolated shower or storm along/south of the boundary on Friday, but PoPs only 20 percent or less. High temperatures on Friday will mainly be in the mid to upper 90s, except for some lower 90s along the immediate coast. Heat index readings look to range up to around 110 degrees southern (and especially coastal) portions of the forecast area on Friday, so another Heat Advisory issuance will be necessary over these areas. Lows tonight are expected to be warm and muggy once again, mainly in the middle 70s for most of the area, but upper 70s and lower 80s closer to and along the coast. DS/12 SHORT AND LONG TERM... (Friday night through Thursday) Issued at 407 PM CDT Thu Aug 8 2024 A broad upper level trough will move across the northeastern US through early next week while upper level ridging remains in place over the local area. Down in the lower levels, a subtle surface trough will be positioned across the coastal areas or just offshore through the weekend before dissipating by early next week. Much drier air will be in place behind this surface boundary and therefore most areas will remain dry through the weekend. The better chance for an isolated or perhaps scattered shower or storm will be along the coast or over southern portions of south central Alabama. Temperatures will be hot on Saturday and Sunday with high temperatures rising into the middle and upper 90s. Lower dew points behind the aforementioned surface boundary will help to keep interior areas below Heat Advisory criteria through the weekend, but it is possible that we may need an advisory for areas along the coast on Saturday. Ridging aloft will strengthen as we head into next week which will help to increase temperatures. Highs each afternoon next week will rise into the upper 90s to around 100 degrees with heat index values climbing back into the 105-110 degree range. We'll likely need additional Heat Advisories across much of the area by the middle of next week. There may be some relief in the form of daily chances for showers and storms, but coverage is expected to remain around 20-35% at best. /14 MARINE... Issued at 407 PM CDT Thu Aug 8 2024 Light to moderate diurnal flow pattern will continue from Friday, through the weekend and into the early part of next week. Offshore flow during the overnight and morning hours, followed by an onshore flow during the afternoon hours. No hazards to small craft expected. DS/12 && .PRELIMINARY POINT TEMPS/POPS...
