Discussion
An Arctic cold frontal has passed through the region and there will be big changes in temperatures today compared to yesterday. The near record warmth of yesterday is gone and N-NW winds will drop temperatures into the 40’s from early morning readings in the 50’s. Strong Arctic high pressure will build to our north and this same cold frontal system will stall out just to the south of here by tomorrow. A disturbance will ride along the frontal boundary zone spreading some snow, sleet and freezing rain into the area by daybreak and then this wintry mix will likely become primarily freezing rain during the day and continue into tomorrow night, possibly mixing with sleet at times. A thin glaze of ice is likely to form tomorrow on untreated road surfaces (and trees, bushes) and travel conditions can become slippery. Looking ahead, much milder weather will return by the middle of next week.
