This Labor Day holiday weekend will end with locally severe thunderstorms rattling parts of the Upper Midwest.

The area at risk for intense thunderstorms encompasses eastern Iowa, southeastern Minnesota and southwestern Wisconsin.

Cities within this zone include Rochester, Minn.; La Crosse, Wis.; and Cedar Rapids, Iowa.

The severe weather danger will last into this evening as noticeably cooler incoming air slices into the warmth pouring northward. The threat will wane later this evening due to the loss of daytime heating.

Fortunately, a widespread outbreak of severe weather is not expected. Still, any violent thunderstorm that erupts will be capable of producing damaging winds and hail. A couple of tornadoes could touch down and cause destruction.

Even after the severe weather danger passes late this evening, gusty winds will continue to whip over the Upper Midwest tonight into Tuesday. The winds are ushering in the fresh shot of cool air.

Winds will gust to around 40 mph at times into Tuesday. Winds of that magnitude could down small tree branches and make travel difficult for drivers of semi-trucks and campers.

The "Dead of Winter," the one-month period when normal temperatures reach their lowest levels, has come to an end for much of the United States. Some people may find it odd that the "Dead of Winter" does not encompass the darkest day of the year (the first day of winter). That is due to a seasonal lag in temperatures. More heat continues to be lost than is gained from the start of winter until this time of year.
