Pleasant Tuesday, then watching midweek storm chances

Pleasantly Dry Tuesday:

Tuesday brings more of the same comfortable summer weather we enjoyed on Monday, with just a little extra warmth. High pressure remains firmly in place across the western Great Lakes, keeping conditions quiet with  mix of clouds and sun. As a result, afternoon highs will climb a few degrees higher compared to yesterday, reaching the upper 80s. All in all, it will be another pleasant July day with very little to disrupt outdoor plans.  

Midweek Storm Chances:

Wednesday looks to stay mostly dry as temperatures continue their upward trend. Most Stateline locales should reach the upper 80s. Winds will begin out of the southeast before gradually turning southwesterly later in the day as a cold front approaches from the northwest. This boundary will have enough support to spark up our next chance for showers and storms, with the highest potential residing north of the Illinois/Wisconsin border. That is where the Storm Prediction Center has placed areas under a level 1 of 5 Marginal Risk with areas further north into Wisconsin being placed under a level 2 of 5 Slight Risk.  

Current indications suggest much of this activity will weaken as it approaches northern Illinois, limiting both coverage and intensity. Even so, a few showers and thunderstorms cannot be ruled out overnight into the early stages of Thursday. Additional rain and storm chances may persist into Thursday afternoon and evening as a weak area of low pressure (M.C.V) slides into the central portions of Illinois. At this point, the better chance for heavy rainfall to the south of interstate 88, but something to monitor as we get into the second half of the week.
