DISCUSSION
Issued at 215 AM CDT Mon Sep 7 2026
One more tranquil day is in store with partly sunny skies with highs in the upper 70s to lower 80s. For tonight, clouds will be on the increase with a chance of showers and isolated thunderstorms across the north. Instability is meager, thus severe weather is not expected. Showers and isolated thunderstorms will move across the area Tuesday morning, continuing into the afternoon. The latest model guidance is considerably lower on the instability late Tuesday afternoon and Tuesday night, generally with CAPE values of 400 to 800 J/KG. 0-6km shear values of 30-40 knots. Bufkit soundings indicated low level winds of 30-40 knots Tuesday night to support strong gusty winds with any storm.
Wetbulb zero heights fairly high, which is a concern for the potential for large hail. Main concern will be the ongoing showers and isolated storms Tuesday afternoon and how that will affect convection into the evening. The latest Day 2 Outlook has a Marginal Risk (Level 1 of 5) for much of the area north and west of the Fox Valley. Showers and storms will come to an end late Tuesday night.
Dry conditions expected Wednesday into Friday. The next chance of showers and storms at times will be from Friday night through the weekend. Confidence is low on timing and placement of convection due to the various model solutions. High temperatures at or above normal through the weekend.
