Area forecast discussion, Jul 31, 11:36 PM CST, 24 minutes before
Area Forecast Discussion...UPDATED National Weather Service Aberdeen SD 1236 AM CDT Thu Aug 1 2019 .UPDATE... Issued at 925 PM CDT Wed Jul 31 2019 Low clouds will expand across the region through the night. Current forecast looks fine. UPDATE Issued at 652 PM CDT Wed Jul 31 2019 00z aviation discussion updated below. && .SHORT TERM...(This Evening through Thursday Afternoon) Issued at 246 PM CDT Wed Jul 31 2019 Winds out of the south southeast and an inversion helping to keep/increase coverage of strato-cumulus, along with a noted increase in humidity. Otherwise nothing aloft to help support convection. As we proceed into Thursday, it looks like the amount of low cloud coverage could expand as humidity increases under the inversion. By the afternoon we're seeing the start of a wave approach from the southwest, rounding the upper high over the 4- Corners region. Elevated convection in the higher terrain west river will drift into the CWA during the evening, but CAMS suggest spotty coverage. That upper system continues across the CWA overnight before moving southeast early Friday. Thus, expect it will also remain humid and warm Thursday night, aside from those cooled by any passing storms. .LONG TERM...(Thursday Evening through Wednesday) Issued at 246 PM CDT Wed Jul 31 2019 Shortwave energy will move over the upper ridge on Friday and help to generate a few showers and thunderstorms across the area. The upper ridging will remain persistent into the middle of next week with temps in the 80s through the extended as a result. Most of the weather will be driven by shortwaves or fairly weak sfc features. No significant systems are in the forecast through the early part of next week. && .AVIATION...(For the 06Z TAFS through 06Z Thursday Night) Issued at 1236 AM CDT Thu Aug 1 2019 Low VFR/MVFR stratus are expected to affect most of the airports except for PIR tonight into Thursday morning. Expect these ceilings to break up Thursday morning into the afternoon as mid and high level clouds spread in from the west with a short wave trough moving in. Also, expect scattered showers and storms to be moving in with this short wave trough possibly affecting PIR/MBG during the evening. && .ABR WATCHES/WARNINGS/ADVISORIES... SD...None. MN...None. && UPDATE...Mohr SHORT TERM...Connelly LONG TERM...Wise AVIATION...TDK
