Area Forecast Discussion
National Weather Service Chicago/Romeoville, IL
109 AM CDT Tue Oct 25 2022
Issued at 940 PM CDT Mon Oct 24 2022
The forecast remains on track this evening. Only changes made were to add a mention for isolated showers the rest of the evening and early overnight hours further east to account for any spotty showers/sprinkles that continue to develop ahead of the main precipitation axis. There is also a narrow axis of gusty showers along the leading edge of the front moving into northwest Illinois that we are monitoring as it continues to push east late this evening toward the area. Increases to precipitation chances/coverage were also made for Monday evening and overnight based on latest hi-res guidance trends showing a slower departure of the “wrap around” precipitation on the northwest side of the low, mainly across northern/northeast Illinois.
We are still anticipating the potential for a corridor of 1.5-2 inches of rainfall (perhaps locally higher) across the area by the time the rain comes to an end. While antecedent conditions have been very dry this could still result in minor flooding in poor drainage areas and some river rises.
