The start of the workweek will see temperatures warming up across the board. Sunshine will be abundant once again, and as winds turn to the south, the temperatures along the shoreline will warm up to the upper 70s and low 80s for most, and mid-80s once you get away from Lake Superior. Then, a cold front approaches the region, bringing the chance for a few thundershowers. Most will remain sub-severe; however, we will still get plenty of lightning and gusty winds overnight. ADVERTISEMENTTuesday, much of the region will see highs top out in the low 70s and upper 60s.
