Localized higher amounts, especially closer to the surface low in our far southern locales and beneath any f-gen banding could result in locally higher amounts depending on where those set up. While some hi-res guidance suggests we may struggle to see hardly any rain at all, think there is enough upper level dynamics combined with the surface low nearby to get at least some shower activity across the area with amounts in the 0.25-0.75" range. The initial warm advective showers some guidance tries to develop ahead of the approaching surface low could arrive as early as this evening though think this should struggle initially due to antecedent dry low-levels.

The eventual phasing of these features and developing surface low will play a role in our precipitation chances tonight through Sunday. Meanwhile a disturbance will be moving within the upper ridge across the Central Plains toward the mid-Mississippi Valley. Southwesterly flow should help warm temperatures into the 80s closer to the shore, though it does look like a lake breeze will try to make inroads by mid afternoon along the immediate Illinois shore which will cool temps off a bit prior to sunset.īy this evening the upper jet becomes more pronounced near 100kt as the upper trough continues to dive south out of Canada toward the area with an associated backdoor cold front sweeping well ahead of it and driving across the area. Today looks dry through the daylight hours with highs expected to be a smidge warmer than yesterday in the low to mid 80s. * Rain expected tonight through Sunday though confidence remains low on amounts (trending lower: 0.25-0.75") * Cool, breezy, and rainy conditions Sunday * Strong backdoor cold front pushes through late this evening bringing gusty winds, 10+ degree temp drop, and building waves Area Discussion for - Chicago, IL (on/off) Help NOTE: mouseover dotted underlined text for definitionĪrea Forecast Discussion National Weather Service Chicago/Romeoville, IL 633 AM CDT Sat Jun 10 2023
