Heat wave will continue this week

Heat advisory until Tuesday evening for the metro area

Our June heat wave will continue for several more days.

The National Weather Service has this definition of heat wave:

A heat wave is a period of abnormally hot weather generally lasting more than two days. Heat waves can occur with or without high humidity. They have potential to cover a large area, exposing a high number of people to hazardous heat.

Our average Twin Cities high temperature is 76 degrees his time of year. The official Twin Cities high temp was 99 degrees on Saturday, and a few spots in the metro area reached 100 degrees or higher. We’re expecting Sunday highs in the mid 90s across much of the metro area.

A heat advisory continues in the Twin Cities metro area from today into Tuesday evening:

Highs in the 90s are expected across most of Minnesota and western Wisconsin Sunday afternoon. There’ll be some 80s in northwestern Minnesota and up along the North Shore of Lake Superior.

Thunderstorm chances

Scattered showers and thunderstorms were occurring in parts of northwestern Minnesota Sunday morning. The thunderstorm chances gradually spread to the east and southeast as we go through Sunday afternoon and evening. At this point, it looks like our thunderstorm chance in the Twin Cities will hold off until sometime after 6 p.m. or so.

The NWS Storm Prediction center shows a marginal risk of severe weather this afternoon and tonight in the dark-green shaded area from southwestern Minnesota into northeastern Minnesota:

Marginal risk means that an isolated severe thunderstorm is possible.

Here’s a look at the thunderstorm potential in northeastern Minnesota and northwestern Wisconsin later today:
