(8:30PM – Wednesday, October 30th, 2024) Wednesday night update on a storm system moving through the region, which will feature a cold front that will sweep across the state from tonight through midday Thursday. This cold front will be accompanied by a broken QLCS, which will feature some severe t’storm threat.
Update…
•No changes were needed on the severe t’storm forecast for tonight through midday Thursday. The going forecast is on track based on the latest weather model guidance.
Timing…
•Tonight – Midday Thursday, October 30-31st.
Location…
•All of Illinois.
Impacts…
•A broken QLCS will accompany a cold front, as it sweeps across the state from tonight through midday Thursday.
•A level 1 severe t’storm risk is in place across all of Illinois from tonight through midday Thursday for the possibility of isolated severe t’storms. Damaging winds and an isolated tornado will be the threats from activity.
Discussion…
•As a storm system moves through the region, a cold front will sweep across the state from tonight through midday Thursday. A broken QLCS is expected to accompany the cold front as it sweeps through. While greater instability and moisture will preclude a higher severe t’storm threat, ample wind shear, forcing, and a strong low level jet will all prove sufficient for a lower end severe t’storm threat with the expected QLCS.
