(9:15PM – Tuesday, April 1st, 2025) Tuesday night update on a potent storm system moving through the region, which will bring another period of high synoptic winds to the state from early Wednesday morning through Wednesday night.
Timing…
•Early Wednesday Morning – Wednesday Night, April 2nd.
Location…
•All of Illinois.
Impacts…
•Peak high wind gusts of 45-60MPH will be likely across much of the state during this timeframe.
•The high winds will have the potential to blow around light-weight/loose items, and may cause isolated tree damage and power outages.
Update…
•With this update, we have expanded higher peak wind gust potential across the remainder of the state. This change was made based on consistency within weather guidance and increasing confidence in the likelihood of more widespread higher wind gusts across a larger area.
Discussion…
•As another potent storm system moves through the region, high synoptic winds are expected across the state from early Wednesday morning through Wednesday night. With a stronger lower-level jet in place and adequate atmospheric mixing, high winds will be likely across the state during this period. Winds on Wednesday will be southerly ahead of the storm system, eventually transitioning westerly Wednesday night, as the storm system passes.
