Fall is almost here, but parts of the Central U.S. will be holding on to Summer temperatures for the next few days.
When we examine the upper level pattern, we can see a strong trough digging into the western United States. As the trough keeps digging south, unseasonably warm air will continue to build across the Central Plains and into the Upper Midwest. As the jet stream moves east it will help to generate severe storms for the Upper Midwest for Friday.
WHAT HAPPENS TODAY?
Just how warm will it be on Thursday? Afternoon temperatures will be 10° to 20° above normal for Wichita, St. Louis and Chicago today and it will likely be just as warm again Friday. We can’t even rule out some record breaking highs later today for parts of Illinois and Missouri.
POTENTIAL FOR RECORD HIGHS!
Changes are on the way…
The colder air building over the western part of the country will continue to push east through the weekend. That means a big swing in the temperatures going from above-normal to below-normal highs by early next week.
