135 FXUS64 KBMX 302005 AFDBMX Area Forecast Discussion National Weather Service Birmingham AL 205 PM CST Sun Nov 30 2025 ...New DISCUSSION... .KEY MESSAGES... Updated at 148 PM CST SUN NOV 30 2025 - Significant rain amounts of one to two inches on average are expected across central Alabama through Tuesday. - Widespread freezing temperatures will return Tuesday night through Wednesday morning. - Another storm system is poised to arrive by the end of the upcoming week with an additional opportunity for significant rain. && .DISCUSSION... (This evening through next Saturday) Issued at 148 PM CST SUN NOV 30 2025 First batch of showers plodding through central Alabama just about as expected, with generally light intensity rain. This rain should eventually move out of all but perhaps the southeast part of central Alabama tonight. The next shortwave trough in the train will dip into the lower MS valley on Monday, and help induce an inverted trough/surface low along the Gulf coast. This will begin the overrunning process into Alabama, with another period of widespread rain expected Monday and Monday night. While there might be enough lift provided by synoptic scale and isentropic processes to produce a few rumbles of thunder, it won`t be widespread and certainly shouldn`t even approach strong (let alone severe) levels. As that system departs the area on Tuesday, the rain will depart with it, leaving dry and chilly weather for the mid-week period. Models are starting to converge on a solution regarding the end of week system, and rain chances have accordingly started to ramp up. /61/ && .AVIATION... (18Z TAFS) Issued at 1146 AM CST SUN NOV 30 2025 Long band of rain showers cutting diagonally across central Alabama this morning should continue to push slowly southward through the afternoon. As the steadier and heavier rain arrives, expect ceiling to lower. Latest model moisture profiles suggest that once ceilings lower to IFR category, they will probably stay there through the rest of the afternoon (even after the rain tapers off). Current sub-1000 ft ceilings north of the rain area supports this notion. There may be a brief period of improvement from late tonight (after 06Z) through Monday morning, as the rain tapers off. However, there is lower confidence in this aspect of the forecast than on the more near term low ceilings. /61/ && .FIRE WEATHER... A series of storm systems will bring at least two waves of rain to Central Alabama through Tuesday afternoon. RH values will remain elevated through Tuesday as a more significant system moves through the region and widespread soaking rainfall is forecast. Dry weather returns late Tuesday through the mid-week period. && .PRELIMINARY POINT TEMPS/POPS...
