There hasn’t been any rain in the QCA since June 26th which when combined with how hot things have been that puts Rock Island and Scott County into the abnormally dry drought stage. Weekend rain chances bring hope of that coming to an end but don’t count your chickens before they hatch.
Heat advisories are in effect across much of the area Friday because of heat index values expected to hit the mid 100s. Be careful outside in that heat. Hot air is building up against a cold front cutting through southern Minnesota and Wisconsin that will push south towards the QCA Friday evening. As it moves into the area, rain chances will increase Friday evening and overnight.
Since this system is coming from the north the rain chances will immediately be higher north of I-80. This is where the bulk of the rain will fall overnight Friday into Saturday. More scattered rain will be likely through Saturday across the board but rain totals will be very random from town to town.
The highest total will come where organized thunderstorms track. Otherwise, most of the rain will be more light in nature so you could have one town with a tenth of an inch of rain and another with 2 inches through the weekend. Download the OurQuadCities app from the App Store and Google Play for an interactive radar to help you track that out.
Rain chances will calm down by Tuesday and then temperatures will be falling off with some more cool air rolling in from the north. We should see high temperatures back down into the mid and lower 80s by next week.
