MADISON (WKOW) – The pleasant stretch of temps continues the next several days before another heat dome sets up for the weekend and into next work week.
The jet stream, which are fast moving winds in the upper levels of the atmosphere, divide air masses. The jet has dipped far south of our area allowing for seasonably warm air to stick around as we tap into air from Canada.
However by Friday, and more so this weekend, the jet will buckle back north and tropical air will move into the Upper Midwest allowing for temps to climb and humidity levels to increase.
Highs through Thursday will range from the upper 70s to low 80s. A weak front will likely stall over our area late Wednesday possibly prompting a few showers and storms with a better threat for wet weather on Thursday.
By Friday, we’ll peak in the mid 80s with upper 80s and low 90s forecasted for the weekend. Feels-like temps with the humidity will be hotter in the low to mid 90s. But, long range computer models indicate actual temps in the low to mid 90s are possible for the first half of next work week with even hotter heat index values.
The Climate Prediction Center’s outlook for the first two weeks of August shows a decent chance of overall above average temps for the Upper Midwest.
