Welcome to the August doldrums.
This time of year weather systems struggle for definition and identity. The weather maps lack strong fronts and air mass contrast in the Upper Midwest. The last cool breezes of spring are long gone. The first fresh fall cold fronts are still a concept void of form.
Natalie Babbitt nailed it.
“The first week of August hangs at the very top of summer, the top of the live-long year, like the highest seat of a Ferris wheel when it pauses in its turning. The weeks that come before are only a climb from balmy spring, and those that follow a drop to the chill of autumn, but the first week of August is motionless, and hot. It is curiously silent, too, with blank white dawns and glaring noons, and sunsets smeared with too much color.”
―Natalie Babbitt, Tuck Everlasting
Summertime moisture bubbles up into spotty thundershowers today. NOAA’s Storm Prediction Center does not include Minnesota in any severe weather risk areas today, but local downpours could be vigorous. NOAA’s HRRR model captures the essence of the spotty cells today.
I am reminded of how some of us pine for an 80-degree day in February or March. This time of year we take highs in the 80s for granted. Summer has ripened indeed.
Dakotas weekend heat wave
The upper air maps favor a significant heat event in the Dakotas over the weekend. A ridge of high pressure topples over into the Dakotas from the west by Saturday.
It’s interesting to see that the heat seems to fade before it reaches Minnesota. But the models for the Dakotas this weekend show a big dome of 100-degree heat. Highs approaching 100-degrees may spill into the Red River Valley and northwest Minnesota Sunday afternoon.

Check out the thermal signature left behind on the ground from this hail core in Nebraska.
Thanks to our friends @NWSNorthPlatte for first highlighting this cool feature on #GOES16 #GOESEast last evening. The supercell produced up to grapefruit size hail at one point! pic.twitter.com/2fmdYQBe0v

California blaze biggest in state’s history, again
Hard to believe California has seen two record-breaking wildfires in the last year. Eight months ago it was #ThomasFire. Today it’s #MendocinoComplex. Extending prayers for safety to all the agencies providing #MutualAid & communities effected by these wildfires @Cal_OES https://t.co/VFutIrGUAi
