406 FXUS63 KABR 021352 AAB AFDABR Area Forecast Discussion...UPDATED National Weather Service Aberdeen SD 852 AM CDT Sat Aug 2 2025 .KEY MESSAGES... - Scattered showers and thunderstorms remain in the forecast through Monday. There is a marginal risk (1 out of 5) for severe storms on Monday. - Surface smoke from wildfires is expected to persist across much of the region through Sunday. Monitor the latest from the EPA and state agencies, as there may be impacts for those sensitive to smoke. && .UPDATE... Issued at 846 AM CDT Sat Aug 2 2025 No changes planned to the today period forecast. && .DISCUSSION... Issued at 317 AM CDT Sat Aug 2 2025 An upper low/MCV continue to spin over north central SD early this morning. The bands of thunderstorms circulating around it have remained sub-severe. This system will slowly make its way east today with a continuous moisture feed provided by low level southerly flow. The absence of a fully open Gulf, though, will keep QPF manageable for the region as the precip remains west of the Coteau until late tonight. Will need to be cognizant of saturated areas east of the Coteau, even with the less than an inch of QPF expected. Precipitation remains in the forecast through Monday due to shortwave reinforcement and the persistent weak sfc low over western SD. By Sunday night, this low meanders into central SD which helps provide forcing farther east. At this time, no severe storms are expected through Monday. The wet pattern continues the first half of the work week with a series of lows moving off the Rockies. There is some drier mid level air expected with the mid week low, so some of the precip may be shunted into ND and MN. Still, ensembles keep a 15 to 35 percent chance of precip around late Thursday through Saturday. The other issue of concern is the near sfc smoke from Canadian and western US fires. HRRR has lessening concentrations for Sunday, but the RAP keeps vsby in that 4 to 6 mile range through Sunday. Have kept smoke mention in the grids, accordingly. && .AVIATION /12Z TAFS THROUGH 12Z SUNDAY/... Issued at 613 AM CDT Sat Aug 2 2025 Terminals KABR,KATY,KPIR,KMBG Smoke continues to hang around this morning with visibilities generally around 5 to 7SM. Some of this may mix with a little fog this morning and early Sunday morning to drop conditions to MVFR. Intermittent showers and thunderstorms are also an issue through tonight but with low confidence regarding where/when -tsra will occur, so left mention out of tafs for now. MVFR cigs are expected to move into KMBG late tonight. && .ABR WATCHES/WARNINGS/ADVISORIES... SD...None. MN...None. && $$ UPDATE...10 DISCUSSION...20 AVIATION...20
