Regional weather view.A hotter, more humid and active weather pattern will develop over the Upper Midwest, A stationary front draping across the area will cause bouts of thunderstorms to develop region wide, some of these storms could go severe at any location across the region, with the best chances being on Saturday or Sunday. Heavy rainfall is possible from these storms. Temperatures will be in the low to upper 80s across Minnesota and Wisconsin each and everyday, with 90s on Sunday, with 90s occurring in Iowa & Illinois most everyday.
Local View.
Note: This forecast replaces my forecast for Friday.
Locally we can expect the chance for thunderstorms to increase the next 3 days, along with hotter and more humid conditions to move in and stay for the weekend. A stationary front will be near the area Friday Saturday and Sunday, causing the possibility of brief pop up thunderstorms to develop. These storms will be the kind that would be brief, it will cloud up, storm, then the sun would come back out. It will not be the all day type of rains. Because of the nature of the storms, and moisture that will be around, storms at any time day or night the next 3 days could be strong, possibly low end severe, So people will want to take the time to keep an eye on the weather just in case, The chance of storms will start to decrease later Sunday. Temperatures will first start off very warm in the upper 80s on Friday and Saturday with, then hot in the low 90s on Sunday, Along with these temperatures It will be muggy all 3 days as well, with fairly warm night lows, but because it is summer and typical for this time of year, heat and humidity should not cause problems.
Friday, Partly Cloudy Very warm and humid. A chance of isolated thunderstorms. Highs in the upper 80s. Friday Night, Partly Cloudy, lows in the upper 60s.
Saturday, Partly Cloudy, Very Warm and humid. Isolated thunderstorms possible through the day, some could be strong, highs in the upper 80s. Saturday Night, A chance of thunderstorms, lows in the low 70s.
Sunday, Partly Cloudy, Hot and humid, a chance of Thunderstorms, some could be strong, especially early. Highs in the upper 80s to low 90s. Sunday Night, Partly Cloudy, lows in the low 70s.
Looking Ahead
Monday Tuesday and Wednesday of next week it dries out, but temperatures will stay typical for July. Then it really starts to heat up and become more storms by Thursday the 14th through the 18th, There will be off an on thunderstorm chances, along with a possible string of 90 degree day temperatures. It cools off to typical summertime temps again by 19th and it is dry. Then July 20th has warmer conditions, and the chance for heavy storms before a sharp cold front cools things off and dries things out just in time for the 21 through the 23rd. But heat and humidity are building back west by this frame, and may be pushing east beyond this time frame.
