It still looks like a consistently warm to very warm May with temperatures above normal. 90-93 is possible by May 18 around here with a surge of 95-100 from the Dakotas to Minnesota!
Overall, rainfall for May looks near normal.
Summer should peak early. Looks like hottest temperatures & some of the most consistent 90s heat of summer will occur in June to early July. Temperatures near/at 100 are possible in a couple of instances.
Rainfall should run a bit below normal overall.
However, beyond around July 10, temperature look to run overall below normal with above normal rainfall right through August.
So, summer is coming on hard & fast & will continue to do so. However, after an early peak in heat waves, cooler than normal weather should dominate July 10-August 31.
It may turn rather dry at times with crop stress early in the summer, followed by much less stress as cooler, wetter weather settles in beyond.
