DISCUSSION

Issued at 209 AM CST Mon Nov 9 2026

Current synoptic features show a relatively zonal jet stream pattern to our north, which has been the reason why we will continue to see our quiet weather regime for Monday and Tuesday. Due to the temperature conditions we saw tonight, along with light winds, fog has formed in parts of the state and around the Missouri River. This will dissipate as the sun rises and temperatures increase. As we remain in this quiet pattern, dry conditions will prevail, along with temperatures in the upper 60s and low 70s, which is 10-15 degrees above average.

The pattern changes on Wednesday as the jet stream to our north forms a troughing feature across the eastern half of the CONUS, and a ridging feature on the western half. The trough axis further developing to our east on Wednesday will result in northerly flow at the 500mb level. This will allow for our current air mass to interact with colder Canadian air to our north, which will promote the development of a low-pressure center. The feature will develop across Iowa, and progress into Illinois by the afternoon hours on Wednesday. Impacts include gusty winds from the northwest, isolated light rain for the eastern half of Missouri, and lower temperatures more November-like for the rest of the workweek. As the trough progresses to our east, and the ridge moves into our area by next weekend, southerly flow will allow for a return for unseasonably warm temperatures by next weekend.

High pressure will keep skies mostly clear through the afternoon. Radiational cooling may lead to another foggy night in some locations, though 3-5 kt winds may help inhibit fog.
