Topics: Hot temperatures today and through much of next week across the Midwest.
Showers and thunderstorms in the north, Great Lakes
Today, a warm front is going to set up across the northern Midwest, stretching all the way east to New England. This frontal boundary will remain in place through the start of next week, and will help trigger some severe weather in northern parts of the Midwest. Currently, there are a few showers and storms ongoing across North Dakota. This morning precipitation will die off. Then, during the afternoon, an area of low pressure will move into the Dakotas, triggering strong to severe thunderstorms. In the east, the same warm front is currently producing showers in the Great Lakes, particularly Michigan. New spotty or isolated showers and storms will develop along the warm front his afternoon, stretching from Minnesota down to eastern Michigan and Ohio. These storms should start much weaker than the storms in the west. Overall rain totals today should remain below half an inch for most areas, but stronger thunderstorms could produce locally higher amounts.
With most of the Midwest now south of a warm front, warmer temperatures are expected across the region; but especially in the western Plains. High temperatures this afternoon will reach the 80s and 90s for most of us today, with more northern and eastern areas staying in the 70s. Low temperatures tonight will be a bit warmer as well, staying in the 50s, 60s, and 70s. Breezy to strong winds are expected today.
Showers and thunderstorms continue in the north
Today’s areas of low pressure will continue to the east tomorrow, pulling a cold front across the Northern Plains and the Upper Midwest. A few showers and storms will be ongoing tomorrow morning, but they should fizzle out as the morning goes on. During the afternoon and evening, a line of showers and storms will develop along the leading edge of the cold front, stretching from Canada down through Michigan, Wisconsin, and Iowas. Severe weather chances appear to be lower tomorrow, as are forecasted rainfall totals. Temperatures, on the other hand, will increase for all but the Northern Plains and Upper Midwest. High temperatures will rang from the 70s in the Northern Plains to the 100s in western parts of the Central and Southern Plains. Low temperatures tomorrow night will stay in the 50s, 60s, and 70s once again. Breezy to strong winds are expected tomorrow.
Heavy rain and thunderstorms in the north
On Sunday, a new area of low pressure in the west will lift the western side of the cold front back to the north as a warm front. As a result, the long warm front will once again stretch across the northern Midwest. Heavy thunderstorms are expected to be ongoing Sunday morning, traveling eastward along the frontal boundary from the Northern Plains into the Upper Midwest. The thunderstorms will grow more widespread during the afternoon hours. Severe weather may be a possibility on Sunday with these storms. Heavy rain is expected, with parts of Minnesota and Wisconsin potentially seeing upwards of 2 inches of rain. Milder temperatures will continue north of the warm front, while the rest of the Midwest stays very warm or hot. High temperatures will again range from the 70s in the north to the 100s in the western Plains. Low temperatures Sunday night will again stay in the 50s, 60s, and 70s. Once again, breezy to strong winds are expected.
