T-storms mark start of a cool late May week

|

A cluster of t-storms is expected to roll through the city this morning with a second batch possible during a period of afternoon heating. With cold air aloft along with a strong NW jet stream, some storms could bring hail and strong winds similar to the storms that struck this area late last Thursday.
Chicago’s high officially made it into the lower 70s Saturday, but lakeshore areas could not get out of the 60s courtesy of this spring’s seemingly persistent northeast winds. Max temperatures in the upcoming week should be capped in the 70s on the warmest days, and on Monday readings may struggle to even reach the lower 60s.
In contrast, the season’s first wave of 100° temps continues to expand in the Desert Southwest, while early season temperature records tumbled from Louisiana to Colorado as readings there soared into the 90s. Dallas-Forth Worth established a new record high Saturday topping out at 99º while the 98º high at Oklahoma City also rewrote the record books.
