DISCUSSION

Issued at 1158 AM CDT Fri Oct 16 2026

Tonight

High pressure, currently located over the Northern and Central Plains, will build quickly east across the area tonight. As this occurs, the surface pressure gradient will slacken. The combination of light winds and clear skies will result is strong radiative cooling. As typical with the NBM, it looked too warm in central Wisconsin so blended in some MOS. Low temperatures will range the mid-20s to lower 30s. There may be even a few locations in the lower 20s in central Wisconsin.

Weekend

The surface high pressure area will shift east into the Great Lakes and into the Mid-Atlantic this weekend. As this occurs, the winds will become southerly and increase into the 10 to 20 mph. High temperatures will warm into the mid- and upper 50s on Saturday and into the lower and mid-60s on Sunday.

Monday through Friday

A 500 mb ridge will build across the region early in the week and it will keep the area dry and unseasonably warm through the remainder of the week. High temperatures will be mainly in the 60s through Wednesday and around 70s Thursday and Friday. Low temperatures in the 30s and 40s through Wednesday and 40s and 50s Thursday and Friday.

AVIATION /18Z TAFS THROUGH 18Z SATURDAY/

Issued at 1226 PM CDT Fri Oct 16 2026

Therefore, have included a VFR TAF at both local sites (KLSE/KRST) for the 16.18Z period. Strong winds will remain the main impact until tonight as they become light and variable.

Winds again increase through Saturday morning from the southwest.
