Update

Issued at 901 PM CDT Fri Oct 30 2026

Moisture is starting to increase from west to east this evening as a shortwave trough approaches. While a few light returns are being picked up on radar, the profile is too dry in the low levels for any of this precip to reach the ground. Forecast still on track to remain dry through most of the day Saturday before some light showers make their way into our southwestern area after sunset as the moisture return increases along with the shortwave.

Short term

(Rest of today through Sunday) Issued at 1110 AM CDT Fri Oct 30 2026

High pressure will keep our wx quiet the rest of today through daytime Saturday. The main feature will be thickening mid and high level clouds. Those clouds will hold temperatures up tonight, so lows will be mainly in the 50s instead of the chilly 40s we have had the past couple of weeks. Saturday will be another warm day in spite of the clouds. Highs will be mostly in the 70s.

By late Saturday, the high pressure will break down as a low pressure wave with deep moisture approaches from the west. We remain optimistic about the outlook for Halloween with most of the area staying dry through Saturday evening. There could be some light drops moving into our southwest counties by dark, but the bulk of the incoming rain will fall after midnight Saturday night, and especially Sunday morning and midday. Temperatures for trick- or-treat will stat in the lower 70s, falling through the 60s.

The incoming system does look particularly strong, so no severe storms are expected, but there may be a few rumbles. Rainfall amounts are expected to be less than 1 inch, so we will not experience much drought relief. The higher totals will fall over the west half. Unfortunately for the east half, and especially Plateau, rainfall amounts from this weekend system may be very light.

Long term

(Sunday Night through next Friday) Issued at 1110 AM CDT Fri Oct 30 2026

Rain will taper off Sunday evening with dry and mild weather returning for Monday and most of Tuesday.

Another low pressure system will approach by midweek. This one will be larger, stronger, and slower moving, so rainfall totals are expected to be greater. Thankfully instability is unimpressive, so we are not worried about severe storms. Most of the midweek rain is expected to fall on Wednesday with a soaking rainfall event expected. NBM shows a 60-70% chance for at least an inch, and a 25-35% chance of some locations picking up closer to two inches.

Dry and mild weather is expected by Friday, lasting through next weekend.

Aviation

(00Z TAFS) Issued at 612 PM CDT Fri Oct 30 2026
