232What 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 Little Rock, AR wrote its last area forecast discussion before this severe thunderstorm warning went out at Nov 10, 11:15 PM CST, 1 hour 32 minutes earlier.
Area forecast discussion, Nov 10, 11:15 PM CST, 1 hour 32 minutes before
Area Forecast Discussion...UPDATED National Weather Service Little Rock AR 1115 PM CST Wed Nov 10 2021 .AVIATION... Updated for 06Z terminals... A trough of low pressure will bring a cold front across the state tonight with showers and thunderstorms. Gusty southwest winds are expected ahead of the front, and northwest winds behind the front. Low ceilings and restricted visibilities (IFR or lower) are expected at times, especially with heavier precipitation. Rain should exit eastern sections in the morning. Clouds will decrease in the afternoon. Expect VFR conditions by mid day or early afternoon as the front exits the state. && .PREV DISCUSSION... (ISSUED 231 PM CST Wed Nov 10 2021) SHORT TERM...Today Through Friday Showers and storms continue developing across OK and KS this afternoon in response to a deepening upper trough, currently positioned over the central Plains, and sharpening attendant cold front draped from northern KS southwestward across West TX. At present, only increasing cloud cover is noted over AR although isolated to widely scattered showers will become increasingly likely by late afternoon into the evening. The cold front will accelerate through AR tonight into Thursday morning as the parent upper trough advances eastward across the Plains. Increasing H850 flow and pre-frontal WAA will further increase convective coverage as the front moves in with virtually the entire area expected to see measurable rain, although lower deep tropospheric moisture content will limit max values to under 2 inches, except in localized heavier downpours. Severe weather potential remains low based on this morning's guidance and trends, although there will be modest potential for a couple of strong storms across western/southwestern AR as convection grows upscale along the surging front. Instability progs keep MUCAPE values just under 1000 J/kg and weakening deep layer shear/kinematics will preclude a more substantial severe weather risk. Damaging winds and isolated severe hail will be possible in the strongest storms this evening and overnight. The front and associated convective activity will push east of the area by very early afternoon at the latest with clearing skies and breezy northwesterly winds in its wake. While drier air will filter in through the day tomorrow, the bulk of cooler air will not arrive until very late in the period as another front quickly drops in from the north on Friday. Some rain is possible over northern sections during the day Friday with seasonably cool air moving in by later Friday and into the long term. LONG TERM...Friday Night Through Wednesday By late Friday, an upper trough axis will be pushing east of the state and NW upper flow will have set in across much of the Plains. The upper ridge that had expanded across the western states will weaken as a SWT moves along the leeward side of the ridge across the northern Plains Saturday, prolonging NW upper flow. As the SWT continues SEward, the larger upper trough will deepen across the Midwest and Ohio River Valley Regions Sunday. At the same time, another upper ridge will build and expand across the western states with continued surface high pressure across the southern Plains. From early to mid next week, the upper ridge will progress eastward, followed by a large-scale upper trough extending from an upper low over Canada southward through the Plains. This will be reflected at the surface as a low pressure system in Canada, with a frontal boundary extending southward. Our next chance for widespread precipitation will be ahead of that boundary the middle of next week. Temperatures are forecast below average until next Tuesday, when southerly flow on the west side of surface high pressure will return warmer southerly air to near normal levels. && .LZK Watches/Warnings/Advisories...NONE. && Aviation...51/57
