708 FXUS64 KBMX 291727 AFDBMX Area Forecast Discussion National Weather Service Birmingham AL 1227 PM CDT Sun Jun 29 2025 ...New SHORT TERM, LONG TERM, AVIATION... .SHORT TERM... (This evening through Monday) Issued at 1227 PM CDT SUN JUN 29 2025 A shortwave trough moving into the region has sparked the development of numerous showers and thunderstorms during the late morning, which will continue through the afternoon and evening hours. Activity will migrate southeastward over the next 12 hours, with occasional strong to severe storms with damaging winds possible. High PWAT values of 1.9 to 2.1 inches are contributing to the thunderstorm development, and heavy rainfall may cause minor flooding issues in any areas in which storms linger. In the meantime, temperatures in the upper 80s to near 90 and dew points in the mid to upper 70s will cause heat index values to reach the upper 90s to lower 100s in spots from midday through late afternoon until storms overspread more of the region and lower air temperatures back into the low 80s. Heat index, while still a little below advisory criteria, may result in heat-related issues for anyone performing outside activities this afternoon. On Monday, higher coverage of showers and storms is anticipated, with slow storm motions and heavy rainfall that could lead to flooding concerns once again. As with today, downburst potential for tomorrow is expected to be lower with saturated soundings (lack of mid-level dry air), but gusty winds with potential for isolated damage are still possible, as is the usual case with summertime storms. With more cloud cover and rain coverage expected, high temperatures should run a couple degrees lower than today. 12 && .LONG TERM... (Monday night through next Saturday) Issued at 1227 PM CDT SUN JUN 29 2025 Thinking remains the same regarding the front reaching the area Tuesday into Wednesday. Lower rain chances late week will allow highs to get back into the low to mid 90s by the weekend, as mentioned in the previous discussion. 12 Previous long-term discussion: (Monday night through next Saturday) Issued at 110 AM CDT SUN JUN 29 2025 Well above average rain chances look to continue into the extended period as a front moves towards the area in association with the eastward progression of the longwave trough. Increasing surface convergence, daytime heating, and very high moisture content will lead to high rain chances on Tuesday. Latest model runs bring the northeast to southwest oriented front into Central Alabama during the day on Tuesday as it begins to slow down and linger across the area on Wednesday. Some dry air may begin to filter into the area from the north on Wednesday, so rain chances will be focused across the southern portions of the area. Dry air advection looks to continue into the end of the week with deep ridging centered to our west promoting northerly flow across Central Alabama. The remnant and diffuse frontal boundary will be situated across the Gulf Coast region. While the coverage of rain will hold highs in the 80s for the first half of the week, a drier forecast in the second half of the week will lead to a warming trend with highs back into the low to mid 90s by the weekend. 86/Martin && .AVIATION... (18Z TAFS) Issued at 1227 PM CDT SUN JUN 29 2025 Shower and thunderstorm activity is developing across Central Alabama this afternoon. Activity should move southeastward through the afternoon and evening, affecting northern sites earlier and MGM later. Lowers vis and cigs will be possible tomorrow morning, especially at terminals that receive rainfall this afternoon. NOTE: AMD LTD TO CLD VIS AND WIND has been added at MGM until further notice due to comms issues. 12 && .FIRE WEATHER... Numerous shower and thunderstorm activity will be prevalent across the area this afternoon and again Monday afternoon. Moisture content will be quite high over the next few days with min RH as high as 65-80% on Monday and Tuesday as a front moves into the area. Winds will be light other than gusts associated with thunderstorm activity. There are no fire weather concerns at this time. && .PRELIMINARY POINT TEMPS/POPS...
