40/SizemoreWhat forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Birmingham, AL wrote its last area forecast discussion before this severe thunderstorm warning went out at Feb 17, 6:10 PM CST, 1 hour 22 minutes earlier.
Area forecast discussion, Feb 17, 6:10 PM CST, 1 hour 22 minutes before
Area Forecast Discussion National Weather Service Birmingham AL 610 PM CST Thu Feb 17 2022 .UPDATE... Mesoscale Update and 00Z Aviation. && .SHORT TERM... /Updated at 0543 PM CST Thu Feb 17 2022/ One supercell moving into the Birmingham Metro area at this writing. Elsewhere, the storms are below severe limits. We have had severe damage reports this afternoon, so remain vigilant into the evening hours and pay attention for further watches or warnings. Parts of the northwest have been removed from the severe threat area, and this progression will slowly continue. There was only a "finger" of instability extending from southwest to northeast and as far north as the storm in Birmingham. Wind and shear fields remain quite high. Therefore, much of the threat will remain south and east of the supercell. Most of this activity was located along a pre-frontal trough with the strong cold front just to our west. The main message remains the same. Severe threat will continue for a few more hours if the overlap of the instability and shear can continue. All wind fields remain high and winds outside the storms may also knock some trees down. These winds will last much of the overnight hours. 75 Previous short-term discussion: /Updated at 0317 PM CST Thu Feb 17 2022/ Most intense convection starting to approach MS/AL state line. Best mesoscale instability parameters remain back in MS, although SBCAPE and MLCAPE have trended up the last couple hours in the western counties of Alabama. Wind and shear fields remain impressive, and any storms that can tap the limited instability and sustain an enhanced updraft will certainly be tornado- possible. Best overlap of instability and shear looks to from Pickens and Tuscaloosa Counties southward. Will also be cautious to not get caught by the "loss of peak heating" fallacy in this situation -- strong warm and moist advection should be more than sufficient to offset any lack of insolation as we transition to sunset. /61/ Friday. The trough will move over the Ohio and Tennessee River Valley Regions on Friday while the associated cold front will push southeast of the state. Expansive surface high pressure from South-Central Canada extending southwest into Texas will build into the region from the northwest. Expect gradual decreasing clouds as lingering showers across the far southeast moves out of the area toward midday. Winds will be out of the north 7-14 mph. High temperatures will range from the mid 40s far north to around 60 far southeast. 05 .LONG TERM... /Updated at 0150 PM CST Thu Feb 17 2022/ After a dry weekend, rain chances return for most periods through at least mid week. Made minor changes to pops, but otherwise no changes needed to the extended forecast. 14 Previous long-term discussion: /Updated at 0338 AM CST Thu Feb 17 2022/ Saturday through Wednesday. With the colder air mass in place, along with clearing skies and calm winds, we'll likely see effective radiational cooling late Friday night into Saturday morning. Therefore, morning low temperatures on Saturday will likely start off in the mid to upper 20s across most of Central AL. A surface high pressure is expected to move through the Midwest as low level ridging builds across the Gulf Coast over the weekend under generally zonal flow aloft. This will lead to mostly clear skies and a gradual warming trend by early next week. Our next weather system begins to take shape on Monday as an upper level wave lifts through the Mexican Plateau and into the ArkLaTex. The wave appears to gradually weaken Monday night into Tuesday, overspreading rainfall across Central AL through the day on Monday. A weak boundary sets up across the Gulf States through at least Wednesday, which would lead to fairly persistent rain chance for an extended period of time. Model guidance is showing anomalous PWATs and vapor transport, so it's possible there could be several rounds of heavy rain Monday through Wednesday. This could lead to some flooding concerns as we head towards the middle part of next week, so it's something to keep an eye on, but I'll wait until we see more run to run consistency on where that boundary will set up before adding any mention of flooding threats into the hazardous weather outlook. 25/Owen && .AVIATION... 00Z TAF Discussion. Showers and storms were moving through the western half of the area at this writing. Most of the activity was near a pre-frontal trough. The storms will move west to east and affect all terminals through at least 08z. Winds outside the convection will remain strong with gusts around 35kts possible at any time. These gusts will remain in the forecast much of the overnight hours. Winds just above the surface increase to near 55kts, but just below LLWS criteria. Ceilings will start off MVFR at most terminals with vis and ceilings up and down. Generally held the ceilings at 010 or slightly better generally through 18z. As the frontal system moves through, expect winds to veer from south southwest to west then north through 18-20z. 75 && .FIRE WEATHER... Showers and thunderstorms will be exiting the southeast Friday morning, with drier air returning to the area. Ceilings will remain below 2kft through Friday morning. Afternoon RH values will be in the 30 to 40 percent range by Saturday and Sunday. Strong southerly winds will become northerly by Friday morning, with surface speeds at 10 to 15 mph. 20ft winds will be 8 to 12 mph. Winds diminish Saturday and turn to the southeast by Sunday. && .PRELIMINARY POINT TEMPS/POPS...
