A powerful line of storms raked across the Plains and the Midwest Monday afternoon into Tuesday morning.
These storms held together and brought tornadoes and damaging winds to much of Iowa and Illinois.
At least 32 tornadoes were reported to the Storm Prediction Center Monday.
We had many tornado warnings and severe thunderstorm warnings across the Mississippi and Illinois Valleys with tornadoes reported at the Davenport Municipal Airport, near De Witt, and Grand Mound in Iowa and near Ladd, Illinois (Bureau County).
Once the sun comes up Tuesday, we’ll see just how much damage was done by the long line of straight line winds.
We had wind gusts of 70 miles-per-hour reported in several hometowns and an 83 mile-per-hour wind gust near Davenport.
Except for breezy conditions and a few isolated showers Tuesday evening to the north, quiet weather is expected through Friday.
However, we could be looking at a winter storm that’ll bring accumulating snow to the area Friday night and Saturday.
This will have to closely watched as we head toward the weekend.
6:12 pm Update: That slight chance for strong thunderstorms this evening has diminished to almost zero chance. However, we still have a good chance for a decent, soaking rain tomorrow night and Friday.
More strong to severe thunderstorms are possible across the Mississippi and Illinois Valley Wednesday afternoon and evening as a cold front brings us a real taste of fall this weekend.
This would be the second round of severe weather today if these storms develop. In the early morning hours Wednesday, winds of 50-75 miles-per-hour were reported across eastern Iowa (73 mph in Muscatine, 66 mph in Iowa City, and 50 mph gusts in Louisa County). Most locations picked up about one-half to three-quarters of an inch of rain.
The Storm Prediction Center has placed most of northern Illinois and a portion of eastern Iowa under a slight risk of severe thunderstorms through 7 a.m. Thursday.
At this point, it looks like hometowns east of the Mississippi River will most likely see the strong to severe thunderstorms.
Here is the forecast for damaging winds (58 mph or higher), large hail (one inch diameter or larger), and tornadoes Wednesday evening and night.
In the morning thunderstorms Wednesday, 0.62″ of rain fell at the Quad City International Airport, which ironically is twice the amount of rain that fell with the remnants of Hurricane Isaac this past weekend.
Behind the storms Wednesday night, another round of wet weather is likely Thursday night and Friday and then much cooler weather takes over this weekend. Highs Saturday will only be in the 70-75° range with overnight lows in the 40s possible.
