North-central US to face resurgence of heat, severe storms early this week

Heat and humidity will build back across the north-central United States early this week, setting the stage for another round of severe weather.

The cooldown that the Upper Midwest experienced this weekend will quickly get erased by a resurgence of heat early this week.

Heat will build throughout the High Plains with some areas like Pierre and Rapid City, South Dakota, flirting with the century mark.

Temperatures will soar back into the middle 80s to middle 90s in Minneapolis, Sioux Falls, South Dakota, and Cedar Rapids, Iowa, on Tuesday following the comfortable start to the week.

Sweltering humidity will accompany Tuesday’s heat surge across the Upper Mississippi Valley, yielding even higher AccuWeather RealFeel® Temperatures.

With the return of heat will come a renewed risk for severe weather as a cold front also enters the picture.

Numerous severe thunderstorms are expected to erupt on Tuesday as a cold front continues to advance southward across the north-central U.S.

Tuesday’s threat will focus on Minnesota and surrounding areas. This includes Minneapolis, St. Cloud and Duluth, Minnesota, and Aberdeen and Sioux Falls, South Dakota.

It is possible that northern areas of Tuesday's severe weather zone will be spared due to lingering clouds and rain Tuesday morning.

“While the main severe weather danger will be around Minnesota on Tuesday, there can also be a localized area of severe weather developing in eastern Kansas and into Missouri,” AccuWeather Storm Warning Meteorologist Brian Knopick said.

The majority of the severe thunderstorms will ignite during the afternoon and evening hours.

In addition to the dangers of damaging winds and hail, Tuesday will bring a greater risk for flooding downpours than Mondays storms did. A few tornadoes may also spin up.

Even in the absence of flooding, motorists planning to travel on stretches of Interstates 29, 35 and 94 should prepare for reduced visibility and a heightened risk of vehicles hydroplaning when traveling at highway speeds.

However, rainfall will generally be welcomed across the northern Plains since a large portion of the upper Missouri River Valley is enduring an extreme drought, according to data released from the U.S. Drought Monitor on Thursday.

Drenching and severe thunderstorms may continue to accompany the front as it pushes southeastward across the Midwest and central Plains Wednesday into Thursday.

The thunderstorms are expected to reach Green Bay and Madison, Wisconsin, and Des Moines, Iowa, on Wednesday. Northeastern Iowa was hit hard by flooding rain on Saturday and could face renewed flooding from these downpours.

Chicago and St. Louis may be rattled by the line of thunderstorms on Wednesday night, followed by Detroit and Indianapolis on Thursday.

The front will open the door for another surge of cooler and less humid air in its wake. Thursday will be a gorgeous day for outdoor plans in Minneapolis.

However, heat will already be quickly building back across the northern High Plains late in the week and into the upcoming weekend.
