Area forecast discussion, Jul 31, 11:41 PM CST, 19 minutes before
Area Forecast Discussion...UPDATED National Weather Service Aberdeen SD 1241 AM CDT Mon Aug 1 2022 .UPDATE... Issued at 1238 AM CDT Mon Aug 1 2022 See below for an aviation forecast discussion for the 06Z TAFs. UPDATE Issued at 814 PM CDT Sun Jul 31 2022 The winds are starting to settle down with the setting sun per the forecast. A cooler night expected under mostly clear skies on tap. No updates needed. Forecast trends in good direction. && .SHORT TERM...(This Evening through Monday Night) Issued at 250 PM CDT Sun Jul 31 2022 Scattered to broken cloud cover has helped to suppress temperatures today. Clouds will likely linger into early evening in the upper shortwave trough across the northeast. High pressure is slated to build in briefly overnight before shifting southeast through the day Monday. Upper ridging and southeast breezes will push temperatures into the 90s west river on Monday. Across the east, expect cooler conditions on the edges of the ridge with less mixing. Southerly winds and a 35 to 40 kt llj will affect the Coteau Monday night but with limited llm and other forcing, no showers are expected at this time. .LONG TERM...(Tuesday through Sunday) Issued at 250 PM CDT Sun Jul 31 2022 The period starts of with somewhat flat ridging over the forecast area early on Tuesday. However, some energy in the flow will swing a trof through the region come Tuesday night. After that, ridging aloft over the southwest CONUS will spread northeast across the Northern Plains, with heights over 588 decameters expected by Thursday across all of South Dakota. Of course, the rising heights will be accompanied by increasing mid level temps. H7 temps appear likely to surpass +13C by the end of this week. The high heights and warm temps aloft should prove to be a hindrance to most convection. That said will still maintain the low pops from the model blend in the forecast until it's more certain that the area is completely capped. There is one period where pcpn chances do stand out. For Tuesday night, energy diving southeast out of Canada, and other energy advecting out of the northern Rockies combine to help carve out a progressive trof over the Dakotas/MN. Toward Tuesday evening, a sfc front will be bearing down on eastern SD. Moisture return ahead of this front will provide for MLCAPES pushing 1700 j/kg over the James/Big Sioux Rvr valleys, but even higher instability over MN. At the same time, the higher deep layer bulk shear values are progged over ND and northern Minnesota. Overtop the sfc front, H7 temps upwards of +12/+15C are expected. So, for the most part, we may well be capped to most convection over northeast SD. SPC has our east outlooked for marginal svr risk, and will accept given that sfc temps nearing 100F late Tuesday may be enough to weaken the cap in some areas. Temperatures through the period will average out above normal for the time of year. && .AVIATION...(For the 06Z TAFS through 06Z Monday Night) Issued at 1238 AM CDT Mon Aug 1 2022 Terminals KABR,KATY,KPIR,KMBG VFR conditions are expected through the period. && .ABR WATCHES/WARNINGS/ADVISORIES...
