610 FXUS63 KABR 020511 AFDABR Area Forecast Discussion National Weather Service Aberdeen SD 1211 AM CDT Fri Oct 2 2026 .KEY MESSAGES... - Temperatures will run near to slightly above normal for the weekend and into next week. - There is a 20-50 percent chance of showers Saturday, otherwise mostly dry conditions are expected through the next 7 days. && .DISCUSSION... Issued at 1211 AM CDT Fri Oct 2 2026 We`ll see a zonal to northwesterly upper level flow regime for the next several days, which is a rather more common flow regime for this time of year. That translates into a mostly dry pattern with back and forth transitions between modified Pacific to Canadian airmass. Surface high pressure overhead this morning pushes off to the east later today, with a tightening pressure gradient and increased southerly winds across central/north central South Dakota. RRFS BUFKIT profiles mixed winds top out around 25kts for Pierre/Mobridge, with the more mixing prone GFS closer to 30kts. Thats about where the NBM tops out. Warm advection ahead of a northwest flow wave Saturday could support mid level clouds with some shallow skinny CAPE. NBM POPs are about 20%, however CONSSHORT is closer to 30 to 50% which better aligns with coverage/intensity of reflectivity depicted by the CAMS. Surface high pressure moves overhead later Sunday morning, with most of Saturday night featuring gradient flow thus limiting frost potential. For Sundays lows, the 25th-75th range in temperatures has a relatively low spread at 3 to 6F and bottoms out in the low 40s. As that high moves off, another tight gradient develops across the Dakotas, somewhere on the order of 8 to 14mb across the state. NBM winds are on the order of 25 to 30kts. The front that follows will likely be dry as the wave and low are well to the north. && .AVIATION /06Z TAFS THROUGH 06Z SATURDAY/... Issued at 1211 AM CDT Fri Oct 2 2026 Terminals KABR,KATY,KPIR,KMBG Expect VFR conditions to continue through the period. The main concern will be increasing winds out of the south-southeast over central SD (MBG/PIR) by late morning through the rest of the period, and at ABR/ATY after 21Z. && .ABR WATCHES/WARNINGS/ADVISORIES...
