KEY MESSAGES
- 15-20% chance for some light rain showers Sunday afternoon. Highs warm to the mid 60s under cloudy skies.
- Good chance (90-100%) for showers and storms late Sunday into Monday morning. Storms Monday afternoon and evening could become strong to severe for areas southeast of a line from Albion to Norfolk to Onawa.
- Rain clears out by Wednesday while more rain chances arrive late this week. Temperatures remain in the 50s and 60s from Tuesday through Saturday.
LONG TERM /TUESDAY THROUGH SATURDAY/
Tuesday will see the deformation zone of the sfc low wrap back around into the area, resulting in more rain showers and storms. Strong cold advection and subsidence behind the low should drive some of the strong H8 winds downward resulting in gusty 40 to 45 mph sfc winds. The windy conditions taper off late Tuesday evening from west to east.
The mid-level wave and any lingering precip across our far north finally departs Wednesday afternoon, although model guidance does show some differences in how fast the wave ejects east. Models hint at another compact, weakening H5 shortwave that ejects from the Rockies area toward the Central Plains Thursday. The track of the wave will largely play a role on if we'll see additional rain chances that day: NBM is currently dry for the area. More rain chances arrive by the weekend, but significant model discrepancies regarding placement of features are seen at this point.
Temperatures largely remain in the 50s and 60s Tuesday through Saturday with the coolest conditions expected across our far northern areas.
AVIATION /06Z TAFS THROUGH 06Z MONDAY/
Issued at 1154 PM CDT Sat Oct 31 2026
Lower cigs around 1000-1200ft are moving in from the west tonight. These will spread east across the area, sinking to around 600-800ft overnight. Could see some patchy drizzle reduce visibility as well, highest chance at KOFK (60%). Cigs will be slow to improve, lifting back above 1000ft mid-to-late morning, and above 2000ft around 17-18Z. We could see some improvement to VFR, especially at KOMA for a few hours during the afternoon before cigs drop back down below 2000ft around 00Z. Winds stay out of the southeast through the period, starting to ramp up in strength toward the very end of the TAF period around 03-06Z Monday.
