A record wet month; now a cool breeze from Canada

The numbers coming out of the Minnesota State Climatology Office, prepared by averaging monthly rainfall totals from around the state, indicate that this June was the wettest June on record for the state of Minnesota.

Heavy rainfalls were so frequent and widespread that June monthly records were set across Minnesota from Luverne on the Iowa border to International Falls on the Canadian border. Preliminary analysis shows that the statewide average rainfall was in excess of 8 inches.

In fact, June was the wettest month of any month of record.

Yesterday's severe weather event just to our south was an impressive way to wind down the month. A massive storm system plowed eastward from Nebraska across Iowa, southern Wisconsin and northern Illinois and then on to Indiana, southern Michigan and just into Ohio overnight.

A cold front brought us cooler Canadian air to begin July, and now reinforcements are blowing across the state on a fresh northwest wind behind a secondary cold front. The cold front and the cyclonic swirl overhead have been enough to generate a scattering of showers.

Falling temperatures this afternoon will continue overnight. Expect lows tomorrow ranging from the low and mid 40s north to the low 50s in the metro area and south. The Twin Cities record low for July 2 is 49.

A gradual warmup will begin tomorrow and accelerate back toward July-like temperatures for the weekend. Thursday probably will be the brightest, most cloud-free day between now and Sunday.
