Tuesday
On Tuesday a low pressure ridge will be riding over the Chicagoland area bringing with it some unstable weather conditions. Tuesday we will have a continued stream of rain and thunderstorms come through the area. Higher possibilities of rain will be towards the afternoon hours, although it’s extremely likely that we will experience rain throughout the day. So a cloudy day with moderate temperatures. Notice the high pressure area in the upper Wisconsin/UP of Michigan in the graphic to the left. This will be making its way down into the region clearing up things for a bit. However until after the low pressure area rides down into the Tuesday night hours.

Wednesday
Come Wednesday things begin to shape up… well for a bit.
As you will see in the Wednesday graphic, the high pressure area starts entering the region and the low pressure starts moving to the southeast. This will set up a day of sunny conditions on Wednesday as well as continued moderate temperatures into Wednesday night in which we will see clear skies and a very comfortable night time temperature of 67.

Thursday

Thursday is shaping up to be a sunny yet warming day, but most likely clear as the high pressure takes up temporary residency in the tristate area. Although there will be a slight and very unlikely chance of precipitation that will increase into Thursday night.
