NWS Birmingham, AL wrote its last area forecast discussion before the first event at Sep 4, 2:49 AM CST, 41 minutes earlier.
Area Forecast Discussion National Weather Service Birmingham AL 349 AM CDT Sun Sep 4 2022 .SHORT TERM... /Updated at 0345 AM CDT Sun Sep 04 2022/ Today through Monday. An upper trof axis just west of the Mississippi River will deepen slightly today and increase lift for areas east of the MS River. This will result in widespread showers and embedded thunderstorms across Central Alabama today, with pockets of locally heavy rainfall. The coverage of rain will increase throughout the day. Cloud cover and cooler daytime temperatures will temper instability, so thunderstorm intensities and coverage will be somewhat limited today. The upper trof axis will remain nearly stationary through Monday, and there will be sufficient lift for scattered to numerous showers tonight and again Monday. A dry slot of mid level air will spread northeast across Northwest Florida and into Southeast Alabama on Monday. This will suppress rain chances and lowered pops south of the I-85 corridor. 58/rose .LONG TERM... /Updated at 0345 AM CDT Sun Sep 04 2022/ Tuesday through Saturday. A positively-tilted upper-level trough is forecast to generally position from southern Texas northeastward all the way through the Great Lakes at the beginning of the period. However, having already been in place for a couple of days by this point, some changes to its characteristics are expected to occur by Wed/Thu. Guidance suggests a couple embedded shortwave disturbances will eject northeast on Tuesday while another potent shortwave dives south from the Upper Midwest through the Mississippi Valley by Wednesday morning. Thereafter, this shortwave will interact with a small upper-low near the base of the trough and the overall system is expected to "cut off" from the northern stream. The more broad upper low is then progged to slowly meander near the lower Mississippi Valley for (possibly) several days. All things considered, this overall synoptic setup will favor continued wet and stormy conditions across the region for all of the long-term period. Due to the slow-moving nature of the cutoff low through this time, the general forecast has not wavered much. I've maintained elevated rain chances most days, with high temperatures resultantly below their respective climate averages. Tue and Wed may end up being the less active days before mid- to upper-level dynamics/forcing increase on Thu. PoPs are the highest Thu through Sat as the upper low positions near Louisiana with southerly deep-layer flow establishing across the I-65 corridor, along with a zone of upper-level divergence. PWs will remain 1.8-2.2" through this period suggesting scattered to widespread showers and thunderstorms each day. We'll need to monitor forecast trends over the coming days as this scenario could lead to flooding issues. 40/Sizemore && .AVIATION... 00Z TAF Discussion. Scattered showers and thunderstorms persist across much of Central AL this evening. This activity should start to diminish overnight, but give way to lower CIGS and VIS. There could be some fog development in places that it rained heavily, but confidence at any specific terminal is low at this time. More rain and thunderstorms develop again tomorrow, with best chances for TSRA being in the afternoon, so will include as a Prob30 group for now. 25/Owen && .FIRE WEATHER... All fire weather elements will remain below critical thresholds over the coming days. Moisture content will remain elevated with periods of showers and thunderstorms for the next several days, mainly in the afternoon and evening. Surface and transport winds will remain in a southerly to southeasterly direction at 5-10 mph this afternoon before becoming more southwesterly tomorrow. && .PRELIMINARY POINT TEMPS/POPS...
