The NWS Storm Prediction Center has issued a

* Severe Thunderstorm Watch for portions of Northern Minnesota

* Primary threats include... Scattered damaging wind gusts to 70 mph likely Scattered large hail and isolated very large hail events to 2 inches in diameter possible A tornado or two possible

SUMMARY...Thunderstorms are expected to intensify early this evening over northwest Minnesota and spread eastward. Damaging winds appear to be the main threat, although hail and a tornado or two are also possible with the more intense activity.

A July cold front tracks across Minnesota Tuesday.

The system triggers scattered thunderstorms and there is a risk for a few severe storms. The highest risk (enhanced) is across northwest and central Minnesota. The risk for severe storms in the Twin Cities is lower.

As I posted on timing earlier today, it still looks like the Twin Cities could see a few storms in the hours surrounding midnight.

After Tuesday’s stormy cool front, our midweek weather looks pleasant across the Upper Midwest. The surface weather maps how a nice little bubble of high-pressure building in over Minnesota Wednesday.

But heat and humidity build again starting Friday. Highs in the 90s will ooze north once again this weekend.

We’ve recorded 9 days at or above 90 degrees so far this year. We could get close to the annual average of 11 days by Sunday.
