Today-Wednesday: Dry and Trending Warmer

While a shortwave remains over the area through the evening, little to no rain showers are expected. A few of the CAMs want to have a few showers form north of I-94 this afternoon so as a result have put in some 10% probabilities for a rain shower in those locations. All precipitation chances subside this evening as the wave dissipates. Shortwave ridging builds in tonight and lingers through Wednesday as a surface high moves over the Upper Midwest. This will keep the forecast area dry and help warm up temperatures slightly over the next couple of days with highs generally in the upper 70s to low 80s.

Thursday-Monday: Shower and Storm Chances Return

Ensemble and deterministic guidance continues to show southwest flow pushing north into the Upper Midwest from Thursday into early next week. As a result high temperatures will be on the increase with most locations seeing highs in the mid to upper 80s. Multiple chance of showers and storms are expected during this period as a few shortwaves move through the region. The first shower and storm chance is Thursday afternoon and then another chance on Friday. The chance on Friday could bear some watching as a surface low develops somewhere over central Minnesota. The associated cold and warm front locations will be important for storm potential. There does not look to be a whole lot of shear with this but between 1500 and 2000 J/kg of SBCAPE look to be possible for Friday indicating that some storms could be strong to severe, but it is too early to tell as there remain several unknowns such as the location of the surface low and the speed at which the trough moves through the region. Other storm chances are possible through the weekend and into Monday. Overall, after a break from widespread storm chances, the end of this week and into early next week looks to be somewhat active.
