It is going to be a story you hear talked about on the national news for a couple of days. It is getting hot outside! Temperatures across the Midwest this afternoon are climbing to the middle 90's to 100° while the heat index climbs above the century mark.High temperatures of the day:
- St. Louis: 100°
- Cape Girardeau*: 98°
- Marion, IL*: 97°
- Paducah*: 97°
- Louisville*: 96°
- Indianapolis*: 95°
- Columbus, IN*: 95°
*Temperatures are indicating hourly observation high temperatures. Official highs for the day will come in later this evening.
Along with the high temperatures, dew points have climbed in to middle 70's (even 80° around Louisville). This is creating heat indices (the feel like temperature) in the 110°-115° range across much of the Midwest. Remember that the dew point is a specific measure of the moisture in the air. Dew point is much more accurate at depicting how humid it is compared to the relative humidity. I know, it sounds weird but its true.
A cold front will slowly move south across the Midwest Tuesday. It should allow for some slightly cooler, less humid air to move in to central Indiana and the St. Louis metro area. However, places like southeast Missouri, western Kentucky and places further south may see a slight increase in temperatures tomorrow as the air is compressed along the front. Typically, air just along and ahead of the front will get warmer than forecast models indicate.
