Skies Thursday afternoon were quick to fill with cloud cover, holding temperatures in the 40s for much of the day. The gusty west wind even brought wind chills down into the low 40s! We’ll hold on to the cloud cover through most of the evening, with skies turning partly cloudy during the overnight. Overnight lows will fall to 30 degrees for most.

A mix of sun and clouds can be expected Friday with high temperatures rising into the mid 50s and southwest/west winds gusting to 25-30 mph during the afternoon.
