Substantial rainfall in the past seven days had a major impact on Minnesota drought conditions, the latest drought monitor report shows. Parts of the state may see thunderstorms on Friday.

Rain dramatically eased drought conditions

Substantial and widespread rainfall last weekend into early this week really took a bite out of the extreme and exceptional drought portions of Minnesota. A widespread 2 to 6 inches of rain fell in portions of northwestern, northeastern and east-central Minnesota.

It’s the biggest improvement we’ve seen in drought conditions this year.

Drought still covers 83 percent of Minnesota, but that’s down from 95 percent a week ago.

The biggest improvement is the elimination of “exceptional” drought — the highest category — and a big cut in “extreme” drought. Extreme drought decreased from 26 percent of the state to now just 8 percent.

When we compare last week’s drought monitor to this week, you can see the biggest change is the extreme drought category (red areas).

It’s worth underscoring that Minnesota’s drought is not over. The rainfall deficit since June 1 in the Twin Cities is still at about 5.74 inches and it’s 8.33 inches in Rochester. Those are down from 8.52 inches a week ago and 10.58 inches, respectively, but still far from adequate.

Summer temps, spotty thunderstorm chances

Cloudy skies will persist much of Thursday with some sun in the afternoon and evening. Highs will be in the 70s across southern Minnesota and 60s north.

Friday and the weekend will see more sunshine with much warmer temperatures. Highs Friday will be near or into the 80s south with 60s and 70s north.

We’ll also see the chance of some thunderstorms as warmer and more humid air surges north. The best chances will be in western, central and northern Minnesota early Friday and then again late in the day.
