045 FXUS64 KBMX 010655 AFDBMX Area Forecast Discussion National Weather Service Birmingham AL 155 AM CDT Tue Jul 1 2025 ...New KEY MESSAGES, SHORT TERM, LONG TERM, AVIATION... .KEY MESSAGES... Updated at 142 AM CDT TUE JUL 1 2025 - There is a Marginal (Level 1 out of 5) risk for severe storms this afternoon and evening ahead of a cold front. Storms will be capable of producing strong wind gusts with isolated gusts up to 60 mph. && .SHORT TERM... (Today through Wednesday) Issued at 142 AM CDT TUE JUL 1 2025 Upper-level forcing will increase quite a bit today as the base of a longwave trough axis advances across the Southeast with a weak cold front set to arrive during the day. Substantial moisture remains in place with PWATs around 2" and dewpoints in the mid 70s. MUCAPE should rise to around 3000-4000 J/kg before convective initiation this afternoon as air temperatures warm into the mid to upper 80s. Saturated forecast soundings indicate lower potential for downbursts, but expect numerous to widespread showers and storms to develop ahead of the front which could evolve into southeastward moving line segments and clusters containing a risk for 30-40 mph wind gusts and isolated instances of severe gusts. Slower moving storms will be capable of producing 1-3 inches of rain in a relatively short time frame, so localized flooding will be possible as well, especially in urban areas. The front will slowly progress through the area tonight and will begin to slow down over the Gulf Coast with winds shifting to the north across much of the area. Moisture content will decrease rapidly from north to south during the day on Wednesday as dry air advection increases downstream of a mid-level ridge axis over the Plains. As such, we will finally see some end to the persistent and above average rain chances for most of the area with only low chances of seeing a shower or storm in our southeast. Expect more sunshine across the north and west with temperatures warming into the upper 80s to lower 90s. 86/Martin && .LONG TERM... (Wednesday night through next Monday) Issued at 142 AM CDT TUE JUL 1 2025 We finally have a mentionable period of dry weather in the forecast with a continental ridge expected to situate to our west through the end of the week. Winds aloft will vary from northwest to northeast providing dry air to the region, and temperatures will climb each day with highs back in the low to mid 90s by Friday and Saturday. Global models indicate a cutoff low will develop near the mid- Atlantic coast over the weekend, but guidance defers on how that feature will evolve early next week. For now, looks like we will stay on the dry side of the low, so not expecting a large increase in rain chances, but it may influence routine summertime PoPs next week. 86/Martin && .AVIATION... (06Z TAFS) Issued at 142 AM CDT TUE JUL 1 2025 There are pockets of IFR ceilings out there currently and expect this low-level cloud deck to expand over the next few hours in addition to some patchy fog development. Ceilings and any reduced visibilities should improve after sunrise, but widespread TSRA is expected again this afternoon as a cold front moves into the area, so expect periodic aviation impacts throughout this TAF cycle. Surface winds will be from the southwest today around 5-6 kts with higher gusts associated with thunderstorm activity. NOTE: AMD LTD TO CLD VIS AND WIND has been added at MGM until further notice due to comms issues. 86/Martin && .FIRE WEATHER... Numerous shower and thunderstorm activity will occur again today as a front moves into the area. Moisture content remains high with min RH as high as 65-80%. Winds will be around 5 mph but higher with gusts associated with thunderstorm activity. Drier conditions will begin to return tomorrow once the front moves through the area. Min RH will decrease to around 50% in the west with higher moisture in the southeast, and slightly drier area-wide on Thursday. There are no fire weather concerns at this time. && .PRELIMINARY POINT TEMPS/POPS...
