(11:45AM – Thursday, March 27th, 2025) Thursday morning update on the combination of a few disturbances moving through the region, a warm front lifting northward, and warm air advection occurring, which will all contribute to waves of showers and t’storms being expected across the state, between this morning and Friday morning. A very low-end and isolated severe t’storm threat will be possible across the state during this period.
Timing…
•Thursday Morning – Friday Morning, March 27-28th.
Location…
•Large portion of Illinois.
Impacts…
•A level 1 severe t’storm risk is in place across portions of the state for the possibility of isolated severe t’storms.
•Hail will be the main threat with activity.
Update…
•With this update, little change was needed, as the going forecast is on track.
Discussion…
•Waves of scattered showers and t’storms can be expected across the state between this morning and Friday morning, as a few disturbances move through the region, a warm front lifts northward, and warm air advection occurs. While surface based t’storm/severe t’storm activity is unlikely, adequate amounts of elevated instability and shear will be present, which will aide in the very low-end/isolated severe t’storm threat possible.
