Much of the Midwest is experiencing a summer cooldown to begin August.
Iowa state climatologist Justin Glisan says both air temperatures and dewpoints are dropping.
“To actually below-normal for this time of year. So it’s going to be very comfortable (and) feel more like late spring versus where we’ve been with heat index values in the triple digits and dewpoints in the upper 70’s and low 80’s. So we’re moving out of that oppressive heat dome.”
He tells Brownfield it was an historically wet July in Iowa and several other states.
“With this moisture surplus that we have (and) low-level humidity, but also these soil moisture profiles recharged, we have fuel for thunderstorms to work off of if we do get into a regime in which we see a more active storm track getting into the first part of August.”
Glisan says there are lean-wet and warm signals for the Upper Midwest the next 10 to 14 days, which indicates increased chances for thunderstorms.
