Area forecast discussion, Nov 10, 5:19 PM CST, 48 minutes before
AREA FORECAST DISCUSSION National Weather Service Kansas City/Pleasant Hill MO 519 PM CST Wed Nov 10 2021 .Discussion... Issued at 327 PM CST WED NOV 10 2021 Key Messages: - Widespread showers and thunderstorms will move east across the area this afternoon and evening, with a marginal threat for severe weather remaining. - Cool and windy conditions expected for the remainder of the work week. As of early this afternoon, convection has initiated over eastern Kansas and raced northeastward, moving across portions of northwest Missouri. A surface warm front has lifted northward to near the Iowa border, providing an expansive warm sector characterized by dewpoints in the mid 50s to near 60. Initial concern was the potential for QLCS-type structures interacting with the backed surface flow along the warm front, but much of the warm frontal region within our forecast area has been stabilized. In the wake of early afternoon convection, portions of far northeast Kansas into northwest Missouri are unlikely to destabilize much further in advance of an approaching cold front. Elsewhere, marginal instability remains in place ahead of the cold front, currently located from near MHK southward through the Flint Hills. Additional thunderstorms have developed over the past hour along this boundary, and convection is expected to expand in coverage during the remainder of the afternoon/evening. Overall severe weather threat remains somewhat conditional, especially as inhibition increases this evening and instability gradually wanes. Will continue SVR Watch 546 for the time being and monitor future trends. By this evening, the aforementioned showers and thunderstorms will move eastward into the forecast area, and likely exit the CWA by early Thursday morning. Severe weather is unlikely with eastern extent, generally points east of the KC Metro. Average rainfall totals between 0.50-1.00" are anticipated, leading to no widespread flooding concerns. Clouds will clear with mostly sunny skies on Thursday. Periods of gusty northwest winds up to 30 mph are possible both Thursday and Friday. The end of the week into the weekend will feature northwest flow aloft, with below normal temperatures occurring during the period. Saturday morning is expected to be the coldest low temperatures in the extended, with readings in the middle to upper 20s. Forecast through the weekend is currently dry, but model spread has become fairly large for Sunday, where some solutions show a stronger piece of energy dropping southeast across the CWA, resulting in some precipitation potential. && .Aviation...(For the 00Z TAFS through 00Z Thursday Evening) Issued at 519 PM CST WED NOV 10 2021 Timing the broken line of storms into the terminals gets them into the between 00Z and 01Z and out of the area between 02Z and 03Z. Will see pockets of MVFR to possibly IFR as the storms move through. Winds shift to the west and northwest behind the front with conditions eventually becoming VFR as skies clear after 06Z. Winds should remain gusty through the remainder of the forecast. && .EAX WATCHES/WARNINGS/ADVISORIES... KS...NONE. MO...NONE. && Discussion...Blair Aviation...CDB
