Today and Tonight

An elevated warm front will move through the area this morning and surface warm front will move late this afternoon and tonight. Soundings continue to show that the deeper moisture and forcing will be found south of Interstate 90. This will result in showers (30-70 percent) and scattered storms from before sunrise into this morning. The 09.00z HREF mean and 24-hour localized probability-matched mean rainfall are only up to a tenth of an inch.

High temperatures will range from the mid-60s to mid-70s. Low temperatures will range from the lower 50s to lower 60s.

Weekend

An anomalously strong ridge of high pressure will provide dry weather and near- or record warmth. With the NBM high temperature anomalies running on the cool side much of this week, raised the NBM temperatures up by 2 to 4F by doing a 50-50 blend of the NBM with the 90th NBM percentile. NAEFS has 850 mb temperatures anomalies between 2.5 and 2.8 standard deviations above normal. This will likely result in near- or record warmth.

High temperatures will range from the upper 70s to mid-80s. Low temperatures will range from the mid-50s to mid-60s.

Monday through Wednesday

A cold front will move through the area on Monday afternoon and night. Soundings suggest that it will likely remain rather dry below 700 mb and that the low-levels may not become saturated along the front until it moves east of the area. As result, kept rain chances from 15 to 25 percent.

High temperatures on Monday will be in the 70s and then be in 60s for Tuesday and lower to mid-60s on Wednesday. These temperatures will be much closer to normal. Low temperatures will range from the mid-40s to mid-50s on Monday night and from the mid-30s to around 50 on Tuesday night.

AVIATION /12Z TAFS THROUGH 12Z SATURDAY/

Issued at 545 AM CDT Fri Oct 9 2026

VFR conditions expected for the next 24 hours at the terminals. A warm front is expected to move through the region later in the day, causing ceilings to gradually lower to between 4-6 kft during the afternoon. Winds will begin to pick up out of the east/southeast through the morning with sustained speeds between 10-15 kts by early afternoon. Through the period, winds will gradually shift to a more south/southeasterly direction with speeds staying elevated through the overnight hours. LLWS looks to be possible during the overnight period, primarily at KLSE, but this will be dependent on low- level mixing.
