Tuesday night’s weather system dropped some impressive rainfall totals across the east metro. Rainfall totals approached 3 inches in a swath from the east metro into northwest Wisconsin. 

Numerous funnel clouds were sighted as the storms spun through. This impressive time-lapse video taken near Rosemount captures the weak, but nearly tornadic, rotation that prompted a tornado warning for the southeast Twin Cities.

Eastern Minnesota and the Twin Cities rides the back edge of the cloud deck from last night’s slowly departing weather system. Expect gradually more sunlight through the thinning cloud deck as we head into the evening hours.

We felt our first taste of summer humidity this week with dew points close to 70 degrees in the Twin Cities Tuesday. A cool front sweeps through Minnesota Thursday. Northwest breezes behind the system blow in a cooler and much drier air mass. 

This surface map loop through Friday shows the fronts pushing through with northwest winds as cooler and driers Canadian high pressure builds in from the north. T.D. Bertha brings rain to the east coast.

These fresher puffs of cooler, drier air bring respites from summer’s heat and humidity to Minnesota.

Much of Minnesota will enjoy highs in the 60s Friday and Saturday. 

We often notice the drop in dew point even more than the temperatures in summer. You can see how the drier air mass with dew points in the 30s and 40s shoves the sticky 60s into eastern Iowa and southern Wisconsin by Thursday evening.
