886 FXUS64 KBMX 040943 AFDBMX Area Forecast Discussion National Weather Service Birmingham AL 443 AM CDT Tue Jun 4 2024 ...New SHORT TERM... .SHORT TERM... (Today through Wednesday) Issued at 402 AM CDT TUE JUN 4 2024 This AM we had a convective complex of storms in MS heading toward us that deteriorated rapidly on radar as they approached the MS/AL state line. Clouds tops have warmed greatly as well. Only light showers remain of the previously bowing segment. What remains over W AL will slowly push ENEWD today. More robust activity from this area is possible as it pushes across the state through the day as we heat up. A few of these storms this afternoon could become strong to marginally severe with damaging winds. At the same time today, another complex of storms currently over OK, is progged to push SE swinging into LA and then around into MS with a portion of it looking to make it into W AL close to sunset. This complex could look messy on radar over AL with interactions between it and any linger seabreeze diurnal late afternoon boundary activity around. This will help storms to stick around with a second round of strong to marginally severe storms possible through the early evening. For severe timing, with 2 rounds, we will trying to keep from getting bogged down in the weeds and just go with "afternoon and evening", 12 noon through around 9 pm when storms look to decrease in intensity over us. If that is not enough, wait there`s more guidance that is showing a 3rd round bringing lingering precip into N AL after midnight from W TN. Gotta love the NW flow train this time of year. This 3rd degraded round may last into the morning hours. Finally, for number 4 as number 3 moves into N AL, a fourth area looks to try to make a repeat performance coming out of OK SEWD into LA then possibly swinging into MS and TWD W AL by late Wed afternoon in deja vu round of storms to round out the end of the short term. Temperatures continue to slowly moderate warming through the short term with mugginess abounding. 08 && .LONG TERM... (Wednesday night through next Monday) Issued at 354 AM CDT TUE JUN 4 2024 A shortwave trough will be moving through the region Wednesday night through Thursday leading to a band of rain and thunderstorms across the area. The highest coverage of storms will likely be Wednesday evening before overnight stabilization decreases the coverage through Thursday morning. More thunderstorms will likely develop Thursday afternoon across the southeastern counties before the trough fully moves out of our area. A cold front will push southward through Central AL on Friday, but guidance hints that there may only be isolated showers/storms with the passage at best. For now, I don`t really have very high of rain chances at all on Friday - only carrying 15-20% chance across the far southern counties. However, it`s possible this could change in the next day or so as higher resolution guidance becomes available to get a better picture of the upper level moisture availability. The front is well to our south by Saturday, which will lead to dry conditions and mostly clear skies across the area. However, in this season/period of northwesterly flow aloft, our next shortwave is likely not far off. Models pick up on another wave sliding through the Ozarks and Mid-MS Valley late Saturday into early Sunday, which could lead to another round of showers/storms Sunday into Monday, but the timing of when it moves into Central AL and produces the best chances for showers/storms is quite variable at this range, so probabilities are generally 30% both afternoons due to the low predictability. 25/Owen && .AVIATION... (06Z TAFS) Issued at 122 AM CDT TUE JUN 4 2024 We currently have a deteriorating convective complex over MS approaching AL state line. Clouds tops have warmed on satellite. Lightning activity has decreased greatly and is now basically SHRA. The bowing feature from earlier has deteriorated as well. As a result, the near short term will be SHRAs for TCL and toward sunrise for BHM/EET. By mid morning the remnants will be near ASN/ANB. Don`t expect much activity for MGM/TOI until later in the afternoon with heating. There is also the threat of another convective complex of storms reaching the MS/AL state line late this afternoon which could bring TSRA to TCL after sunset if it pans out. Outside of convection, MVFR stratus is expected to develop over the next couple of hours. A few areas could go down to IFR as well. Conditions should rebound to VFR 15-16z S to 16-18z N areas. 08 && .FIRE WEATHER... A warm and humid air mass will persist through at least Thursday before a frontal boundary pushes into the region on Friday. Scattered showers and thunderstorms are possible today before becoming more widespread Wednesday. Generally light southerly flow is expected today before shifting westerly Thursday ahead of the approaching frontal boundary. && .PRELIMINARY POINT TEMPS/POPS...
