High pressure remains in control today. This ridge will allow for valley inversions that will limit our warming potential. Highs will be in the teens and 20s through Wednesday. Isolated showers will be possible late Wednesday for areas north of I-90.
Gradual changes will take place later this week as a storm system moves into the area. Highs will be in the 20s and 30s Thursday, warming to the 30s Friday and the 30s to around 40 by the weekend. A chance of rain and snow Friday and again Sunday and Monday.
