The heat is here for the weekend and -- oof -- was it a steamy Saturday! Temperatures were in the 80s and 90s, heat index values will near and above 100°! Take a look at some of the numbers from the upper Midwest (from National Weather Service in La Crosse)
And the heat gets cranked up a little bit more on Sunday... There may be a few showers and clouds in parts of Iowa Sunday morning in the wake of a complex of storms in South Dakota and Minnesota. But most likely there will be a lot of sunshine, heat, and humidity.
Dew points are going to be very high (70° = uncomfortable, 75°+ = gross, gross, gross) Sunday afternoon
The combination will send heat index values into the triple digits, possibly even higher than Saturday--
This is all out ahead of a cold front that will sweep through the area Sunday evening. The front will bring showers and thunderstorms, some of which may be strong. Heavy rain is likely, especially with dew points and moisture levels (kind of go hand in hand there) on the high side.
Showers and storms will continue through the night Sunday and may linger into early Monday. Here's a look at the rainfall totals through Monday:
That will be some beneficial rain for portions of western Iowa where there are severe drought conditions right now. Here's the latest drought monitor:
The rain will come to an end and the temperatures and humidity will drop as we head into next week. Dew points will be in the mid 50s to mid 60s on Tuesday, which will feel a LOT nicer outside!
One more day of high heat and humidity and there is a light at the end of the tunnel!
