Regional Forecast Map.

A warm summer-like airmass has overtaken much of the Upper Midwest and this will continue for the next few days. However a strong fall storm system will split the region in half keeping the summer-like warmth to the south and keeping cool-rainy conditions to the north. The two airmass colliding will cause the threat for a severe weather outbreak across parts of Nebraska, Southeastern Minnesota, Northern Missourri, Wisconsin and Northwest Illinois on Friday as the cold front pushes through. Heavy Rain appears likely along and north of the warm front across Southern Minnesota and Wisconsin. The storm system will have quite a punch to it un-like other storms we’ve had and other weather outlooks are saying the severe weather threat may be quite a bit higher then we’ve seen in awhile. Saturday after the passing of the cold front significantly cooler temperatures will be felt across the entire Upper Midwest.

For the local area expect that we will have one more sunny, dry day Wednesday with sunny skies and highs in the middle 80s and lows in the lower 60s which is some 10-15 degrees warmer then where we should be. Temperatures will be near 80 both Thursday through Friday but rain chances will increase. Thursday the chance for isolated thunderstorms will begin to increase as a warm front lingers near the area and these storms could develop at any time during the day Thursday. Friday will bring the best chance for rain along with the threat for severe thunderstorms developing. It appears that the afternoon and evening a ling of strong to severe thunderstorms will push in from the west. Strong winds and heavy downpours will be the main threats, however there will be other threats as well. Saturday will only have a chance of morning thunderstorms with the afternoon being significantly colder with strong northerly winds. Highs will only be in the upper 50s to lower 60s after being near 80 most of this week. Clearing skies Saturday and Sunday nights could allow for temperatures to fall into the upper 30s, the 1st for most of the area especially North towards the Waterloo area. I will have updates on this frost chance as it approaches. Monday through Tuesday looks beautiful with cool temperatures in the middle 60s and lows in the lower to middle 40s.

Wednesday, Sunny skies and warm, breezy south winds to 25MPH Highs in the lower to mid 80s. Wednesday Night, Partly Cloudy with lows in the middle 60s.

Thursday, warm and humid, A chance of showers and thunderstorms developing during the day. Breezy south winds with highs in the low 80s. Thursday Night, Partly Cloudy with a lingering shower or thunderstorm, lows in the middle 60s

Looking Ahead

We may be able to pull off one more nice day on Thursday before the next storm system arrives for next weekend. Another strong fall storm system brings a cold rain spreading through the Midwest bringing steady rain chances both Friday and Saturday the 11th and 12th. This will be leaving a cool fall like start to the week of Monday the 14th. This will bring another chance of frost which appears to be a much better chance this this weekends. It remains cool and sunny through the 17th of October.
