KEY MESSAGES

- Scattered light rain showers and drizzle are expected through this evening, with damp conditions during the main Trick-or-Treat period.

- Warmer than normal temperatures continue, particularly Sunday and Monday.

..Rain Event Monday/Tuesday

A slow moving H5 trough is expected to deepen as we head into Sunday and Monday. This will bring widespread rain chances into the area through Tuesday, with around an 80 percent chance of at least a half inch of rain across southeast North Dakota and west central Minnesota. Chances decrease further north and west. The heaviest rain will occur in response to a deformation zone that forms as the upper low moves off to the northeast. As such, the track of the low will ultimately determine where the heaviest amounts fall, which could be upwards of 2 inches to 3 inches inside the deformation band. Outside this band, the range will be lower, likely in the 0.5 inch to 1 inch range.

AVIATION /00Z TAFS THROUGH 00Z MONDAY/

Issued at 640 PM CDT Sat Oct 31 2026

Conditions are expected to deteriorate overnight, with current IFR and MVFR turning into LIFR and IFR in the next few hours. Fog and drizzle will be hazards at KDVL, KGFK and KFAR, with drizzle at KBJI and KTVF. Ceilings will improve mid to late Sunday morning back into MVFR at most terminals. There is some uncertainty in when this improvement will occur, and therefore IFR may linger a bit longer then the current set of TAFs shows.
