KEY MESSAGES

- Gusty southwest winds to 50 mph in northeast ND this afternoon will bring minor wind impacts. Wind Advisory in effect through 7 PM.

- Chance for thunderstorms returns mid to late this week. This includes potential for strong to severe storms, however, confidence remains low regarding details.

- Late summer heat forecast to return this weekend.

..Late summer-like heat this weekend

Ensemble guidance strongly suggests in strong upper ridging into the Upper Midwest this weekend. This will promote increasing temperatures aloft, as well as the migration and pooling of moisture near the surface. This will not only allow opportunity for 90s back into the forecast, but also high humidity. As of now, Friday and Saturday look to be the days where these two may align to bring heat indices well into the 90s, and perhaps into the low 100s (10 percent chance of occurring). While Saturday looks to be hottest within the forecast period, this could also extend into Sunday, although confidence is low in this.
