Area forecast discussion, Aug 8, 12:30 PM CDT, 1 hour 57 minutes before
Area Forecast Discussion National Weather Service Topeka KS 1230 PM CDT Sun Aug 8 2021 ...Update to aviation forecast discussion... .DISCUSSION... Issued at 326 AM CDT Sun Aug 8 2021 As advertised, the mid-level trough has progressed into the Plains this morning with non-severe showers and thunderstorms continuing across the forecast area ahead of this feature. This precipitation is progged to weaken and exit the area around sunrise this morning as skies begin to clear from west to east. The trough continues its slow trek eastward through the rest of the day, not making it east of the CWA until late this evening. As clouds clear and daytime heating commences, MUCAPE values should rebound to 2000+ J/kg by late this morning with bulk shear around 30 kts. With support from the upper trough along with a few outflow boundaries from storms during the morning, expecting additional convection to develop ahead of the surface trough axis mainly across northeast and east central Kansas. CAMs depict some scattered convection developing during the mid to late morning, although the better chances come during the mid afternoon as the already weak cap becomes even weaker. Most likely locations for afternoon storms would be along and south of the Kansas Turnpike. Some of these storms could be severe with damaging winds and large hail being the main hazards. Convection shifts southeast by midnight on Monday. Brief ridging builds in for Monday with a thermal ridge extending across the Plains. Temperatures warm into the middle and upper 90s (with some low 100 readings in north central Kansas) and dewpoints in the mid 60s to the mid 70s will lead to heat index values around 105. Similar conditions are possible on Tuesday, although a passing shortwave and associated precipitation and cloud cover may keep heat indices from reaching heat advisory criteria. Will hold off on any heat headlines for now. Storms that develop Monday afternoon/evening near a surface trough across northwest Kansas and southern Nebraska may move into north central Kansas Monday night, but model consensus is for these to dissipate before entering the western part of the CWA. Temperatures remain in the 90s through Thursday before cooling slightly to end the week. A couple of passing waves may lead to periodic precip chances Wed-Fri, but details in timing and location remain uncertain this far out. && .AVIATION...(For the 18Z TAFS through 18Z Monday afternoon) Issued at 1230 PM CDT Sun Aug 8 2021 VFR conditions are expected through the period. Winds south to southwest around 11 kts with gusts to 22kts expected through 01Z then decreasing to 10 kts or less for the rest of the forecast period. TSRA chances look best to the southeast of TOP and FOE terminals and have left out of the forecast. Will continue to monitor and make updates as needed. && .TOP WATCHES/WARNINGS/ADVISORIES... NONE. && DISCUSSION...Flanagan AVIATION...53
