(10:30PM – Thursday, June 20th, 2024) A storm system will move through the region from Saturday into Sunday, bringing a round of rain and t’storms to portions of the state from Saturday afternoon through early Sunday morning. Severe t’storms will be likely with some of this activity across outlooked areas during portions of this timeframe.
Timing…
•Saturday Afternoon – Saturday Night, June 22nd.
Location…
•Northern & Central Illinois.
Impacts…
•A level 1 to 2 severe t’storm risk is in place across Northern and Central Illinois from Saturday afternoon through Saturday night for the likelihood of isolated to widely scattered severe t’storms. Damaging winds, hail, and an isolated tornado will be the threats from activity.
Discussion…
•As a storm system moves through the region from Saturday into Sunday, a trailing cold front will sweep across the state. Showers and t’storms will develop in the vicinity of this cold front on Saturday afternoon across Southern Wisconsin, Eastern Iowa, Northwestern Illinois, and Northern Missouri. This activity may organize into a few loose clusters as it tracks east-southeastward across the state from Saturday afternoon through early Sunday morning. The focus will be on Northern and Central Illinois, where an environment will be in place that will be supportive of severe t’storms. Thus, some of the activity during the period from Saturday afternoon into Saturday night will be severe across the outlooked areas. Forecast soundings suggest damaging winds and hail will be the greatest threat from activity, though an isolated tornado can’t be ruled out.
