Area Forecast Discussion National Weather Service Huntsville AL 657 AM CST Wed Feb 23 2022 .UPDATE... For 12Z TAFS. && .NEAR TERM...(Today) Issued at 516 AM CST Wed Feb 23 2022 A cold front continues to shift very slowly southeastward across the TN Valley this morning, beneath mid/high-level west-southwesterly flow to the north of a subtropical ridge. Based on current surface observations, the front should clear the forecast area shortly before 12Z, with lingering postfrontal rainfall expected to quickly end across the southeastern half of the region between 12-15Z. Light- moderate north-northeasterly flow in the wake of the front will advect colder air into the region, emanating from a strong/cold anticyclone over the northern Plains. Given this and expectations that low stratus clouds will persist for much of the day, we think daily highs will occur around or shortly after 12Z, followed by steady or slowly falling temperatures. Latest model consensus continues to suggest that the cold front will eventually stall across central AL late this afternoon, as a closed upper low across CA/NV begins to open into a trough and eject east- northeastward across the southwestern CONUS, inducing a broad region of surface pressure falls along the TX coast. Elevated warm advection and moisture transport in response to these processes will contribute to expansion of elevated convection currently in progress across the southern Plains, with the eastern edge of this regime perhaps reaching our western CWFA border by 00Z. .SHORT TERM...(Tonight through Friday) Issued at 516 AM CST Wed Feb 23 2022 Showers and a few elevated thunderstorms will continue to overspread the TN Valley this evening, to the north of the stalled surface boundary that will begin lifting northward as a warm front shortly after sunset. Although effective bulk shear will be sufficient for some organized convective structures producing very small hail, weak lapse rates aloft will generate elevated MUCAPE less than 250 J/kg and lightning should be the main risk with this activity. There is still a bit of disagreement concerning the speed at which the warm front will cross our area during the morning hours on Thursday, with at least a limited threat for another axis of heavy rainfall to setup across northwest AL/southern TN. Although this would result in additional flooding, too much uncertainty exists to issue another Flood Watch at this point. The capped warm sector will become established across the entire region by Thursday afternoon, with dry conditions and temperatures warming into the mid 60s-around 70. To our southwest, a surface low is expected to become more defined across central MS by 00Z Friday, as the northeastward ejecting mid-level trough across the southwestern CONUS emerges over the central Plains. The low is predicted to deepen as it lifts northeastward through the TN Valley and into the central Appalachians early Friday morning, dragging a strong cold front across the local area. Although wind shear will be more than adequate for severe convection, instability appears meager at best, with a line of low-topped convective showers expected to evolve along the cold front. The showers may still produce locally strong winds based on the presence of a 40-50 knot southwesterly low- level jet, but the coverage of thunderstorms and temporal extent of heavy rainfall will be very limited. The front should exit the region around 12Z Friday, with lingering light rain ending across the southeastern zones shortly thereafter. With stratus clouds not expected to dissipate until late afternoon, modest cold advection will lead to highs in the u40s-l50s. .LONG TERM...(Friday night through Tuesday) Issued at 516 AM CST Wed Feb 23 2022 Global models suggest that a positively-tilted mid-level wave across the northern Rockies on Friday evening will dig southeastward this weekend, perhaps evolving into a cutoff low by the time it reaches the southern Plains. A surface trough across the western Gulf of Mexico will become more defined as this occurs, with elevated warm advection resulting in a fairly rapid increase in mid/high-level clouds by Friday evening. As synoptic scale ascent strengthens with the approach of this disturbance, cloud bases will descend, leading to gradually increasing chances for precipitation at the surface. This may occur as early as the predawn hours on Saturday which would result in a rain-snow mixture with temps in the l-m 30s, but is more likely to occur during the day, when warmer temperatures in the l-m 40s will support light rain. Based on latest guidance, vertical motions appear to be maximized on Saturday evening/early Sunday morning, at which point stratiform precipitation will become fairly widespread across the region. Similar to Friday night, this could also occur as a mixture of rain and snow, especially across the northern portions of the TN Valley, where boundary layer temps will be a bit colder. The precipitation shield will begin to erode from the west late Sunday morning, due to the advection of drier air aloft. A mid-level ridge will build across the region on Monday in the wake of the departing trough, with a return to zonal flow expected on Tuesday. This will lead to dry conditions with a gradual warming trend as temperatures are predicted to reach the m-u 50s by Tuesday. && .AVIATION...(For the 12Z TAFS through 12Z Thursday morning) Issued at 657 AM CST Wed Feb 23 2022 Low stratus clouds and light mist will persist at the HSV/MSL terminals this morning, in the wake of a cold front. Based on recent sfc observations, we have included IFR cigs in the TAFs thru 15Z, with MVFR cigs btwn 1500-2500 ft anticipated thereafter. Additional showers and perhaps a few elevated convective cells will spread eastward across the region this evening ahead of a northward-moving warm front. We have indicated TEMPO groups for this activity btwn 01-05Z, followed by gradual veering of sfc flow to the ESE and additional IFR cigs late in the forecast period. && .HUN WATCHES/WARNINGS/ADVISORIES...

Hazardous Weather Outlook National Weather Service Huntsville AL 651 AM CST Wed Feb 23 2022 ALZ001>010-016-TNZ076-096-097-241130- Lauderdale-Colbert-Franklin AL-Lawrence-Limestone-Madison-Morgan- Marshall-Jackson-DeKalb-Cullman-Moore-Lincoln-Franklin TN- 651 AM CST Wed Feb 23 2022 This Hazardous Weather Outlook is for north Alabama and portions of southern middle Tennessee. .DAY ONE...Today and Tonight... Areal and river flooding are currently in progress across much of the Tennessee Valley, and a Flood Watch remains in effect until 12 PM CST today. Otherwise, a few thunderstorms will be possible across the region this evening and during the early morning hours on Thursday, ahead of a northward-moving warm front. Very small hail and frequent cloud to ground lightning could occur with these cells. Another band of moderate to heavy rainfall may develop from northwest Alabama into southern Tennessee, leading to a renewed risk for flooding in these areas. .DAYS TWO THROUGH SEVEN...Thursday through Tuesday... Isolated thunderstorms will be possible throughout the day on Thursday, with a few additional rumbles of thunder possible within a band of moderate-heavy showers that will progress southeastward early Friday morning along a cold front. Although storms are not expected to be severe, strong wind gusts of 40-50 MPH will be possible with the band of showers early Friday morning. Another storm system will impact the outlook area this weekend, with a wintry mixture of rain and snow possible on both Friday night and Saturday night. Minor accumulations of snow will be possible Saturday night, primarily across the northwestern half of the region. .SPOTTER CALL TO ACTION STATEMENT... Activation of storm spotters and emergency management personnel is not anticipated at this time. 70/DD
