Highs on Tuesday and Wednesday are forecast to reach into the 20s and near 30 degrees, though temperatures above freezing remain unlikely, Pfahler said.

Precipitation chances remain low, with only a slight possibility of light snow during the same period. Pfahler noted that any snowfall would likely be minimal, with accumulations of an inch or two at most.
Looking ahead, the National Weather Service anticipates a warming trend next week, with temperatures likely rising above freezing.
