379 FXUS63 KDMX 240444 AFDDMX Area Forecast Discussion National Weather Service Des Moines IA 1144 PM CDT Sun Aug 23 2020 ...Updated for the 06z Aviation Discussion... .DISCUSSION.../Tonight through Sunday/ Issued at 253 PM CDT Sun Aug 23 2020 Continued focus on the heat throughout the work week with just some patchy fog possible across the north-northeast early Monday morning. The other concern or uncertainty is the impacts of the wildfire smoke streaming in from the west on Monday and Tuesday. Weak flow and enough low level moisture around to have a mention of patchy fog across the northeast by Monday morning. Similar trend to this morning with the fog developing. Large thermal ridge continues to strengthen over the western two- thirds of the country and keeping Iowa hot through Thursday before the ridge begins to break down by the end of the week. 850mb temperatures by Monday warm to around +25C and there is some mixing that develops tomorrow afternoon. Confident with the mid to upper 90s for highs Monday but with the last several runs of the HRRR continually bringing in the wildfire smoke, uncertainty with how much of an impact his plays on temperatures as well as air quality. Can already see hints of smoke over the Dakotas and western Nebraska via GOESEast satellite trends and it doesn't appear to be impacting current temperatures attm. At any rate, hot, dry, and a little breezy in the afternoons Monday through Wednesday. Friday through the weekend...a much needed cool down is anticipated during this period but low confidence with any significant precipitation maker with the lingering tropical systems hoarding the main moisture source. && .AVIATION.../For the 06Z TAFS through 06Z Monday night/ Issued at 1142 PM CDT Sun Aug 23 2020 Little change from previous forecast.
