Active Weather Pattern Expected From the Midwest to the Southern Plains; Dangerous Heat Likely in Southern Texas

A strong storm system will bring numerous to widespread severe thunderstorms across portions of the Midwest and Upper Great Lakes Tuesday. Tornadoes (a few strong), damaging winds and large hail are expected. Record high temperatures will be possible over southern Texas the next several days. This may lead to dangerous heat concerns especially for areas already without power. Read More >

Storms are quickly weaking as they move east across our forecast area. Sub-severe storms will still pose threats for frequent lightning and heavy rain, as well as potential for strong, gusty winds.
Scattered strong to severe thunderstorms are possible tonight, with the best potential in the 6 to 11 pm EDT time frame over NW IN and SW MI. Wind gusts up to 60 mph and hail up to 1 inch in diameter are the most likely hazards. Heavy rain and lightning will also be a concern. There is lower confidence as we are uncertain regarding how intense the storms will be once they move into our area, and whether or not they can maintain that intensity as they move eastward. Coverage is also in question. The storms should gradually weaken as they move east later tonight. Otherwise, expect variable cloud cover with lows in the 60s. There is additional severe potential Tuesday and Wednesday.
Scattered severe storms are possible late Tuesday, as The Storm Prediction Center maintains a Slight Risk (level 2 of 5) over part of our forecast area. A line of strong to severe storms will develop off to our west and move east across our forecast area late Tuesday/early Wednesday. The main concern is damaging wind gusts (60+ mph), with lower (but still possible) threat for an isolated tornado or two.
