- Cool nights and mild days will continue.

- No rain for the foreseeable future. Drought conditions are going to worsen.

Short Term

(Tonight through Wednesday Night) Issued at 1024 PM CDT Mon Oct 19 2026

Dry high pressure will remain in control through the forecast period. Nights will stay seasonably cool in the 40s and daytimes will be a few degrees warmer than normal, mainly in the 70s. Relative humidity values will dip each afternoon, enhancing risk from fires, but winds will be generally light.

Temperatures will gradually warm late week and this weekend, but nothing extreme is expected. Otherwise, drought conditions will worsen as the extended dry pattern continues.

Aviation

(06Z TAFS) Issued at 1238 AM CDT Tue Oct 20 2026

VFR conditions prevail. Daytime winds will be NNE 5-7 kts. Will watch for patchy fog at SRB and CKV, but don't expect major impacts.
