Local and Metro views.Tonights and Mondays Severe Weather Risk!
Getting right to the point there will be a risk for severe thunderstorms tonight as a warm front pushes north. Storms will develop to the west of our area and push east over the evening hours and overnight. The main threats for our local area will be large hail and damaging winds along with heavy rainfall and flooding. Especially in Goodhue County.

After the passing of this warm front we will be under the influence of a short lived but potent heat wave which will bring very hot temperatures and very high heat index values to our area. Under sweltering sunshine and very high dewpoints in the 70s, High temperatures will reach the middle 90s and it is not out of the question that some places could hit 100.F or get close to it, especially on Tuesday when the heat wave peaks. Even without the actual temp in the 100s range. Heat index values will be well into the lower 100s during the day and not fall out of the low 80s at night.
