476 FXUS63 KABR 201729 AAA AFDABR Area Forecast Discussion...UPDATED National Weather Service Aberdeen SD 1129 AM CST Fri Feb 20 2026 .KEY MESSAGES... - Temperatures in the upper teens to 20s (roughly 10 degrees below normal) will continue through this weekend, with the exception of highs in the lower to mid 30s over south central SD Saturday. A warming trend is expected at the start of next week. && .DISCUSSION... Issued at 1043 AM CST Fri Feb 20 2026 Northwest flow and an upper low over Lake Superior continue to pull some flurries into the region today. The upper low is pretty slow moving and may keep some flurries over west central MN into this evening. Though radar returns this morning indicate more widespread light snow, think the drier air and lack of forcing is undercutting most of it west of I-29. High pressure builds in from the northwest tonight through Saturday night. This cwa will be at the edges of the high for the next 48 hours allowing northwest winds to become breezy (20 to 35 mph) under the jet. Coteau winds, with 50 kts at 700 mb on Sunday, may need an NBM 90th boost in the grids to reflect some 40 kt gusts. There`s a lack of consistency in the models starting Tuesday regarding system track and timing and precip chances. The ECMWF is much weaker on a midweek trough than the latest 12z GFS, keeping the ensemble guidance to 25 to 35% pops. All guidance does point to some warmer temperatures under the building ridge Monday and Tuesday. && .AVIATION /18Z TAFS THROUGH 18Z SATURDAY/... Issued at 1127 AM CST Fri Feb 20 2026 Terminals KABR,KATY,KPIR,KMBG Flurries will persist near KABR and KATY until between 21z and 0z. KATY may still see some MVFR cigs move back in this afternoon with the lingering wraparound from the upper low over Lake Superior. VFR conditions are expected at all sites with snow exiting this evening through Saturday morning. && .ABR WATCHES/WARNINGS/ADVISORIES... SD...None. MN...None. && $$ DISCUSSION...20 AVIATION...20 |
