After tornadoes hit Saturday afternoon and evening, another round of thunderstorms,
some possibly severe, appears on tap today. Strong southerly winds wrapping around the
backside of high pressure centered over the southeastern U.S. continues to pump very
warm, humid air north into the Midwest and Great Lakes. Thunderstorms could pop up
almost anytime, but the peak heating afternoon and early evening hours appear most
likely. The National Weather Service Storm Prediction Center has projected a wide area
from the southern Plains to the western Great Lakes, including northeast Illinois and
northwest Indiana, for a chance of severe storms today.
RELIEF IN HEAT AND HUMIDITY IN SIGHT
A cold front is expected to move through the metro area Monday, preceded by showers
and thunderstorms, followed by a cooling less humid northwest flow. Hot, humid air is
forecast to briefly return midweek, peaking Thursday before the arrival of another cooling
cold front Friday. A cooler, less humid air mass should then hold through next weekend.
