With the precipitation of the present winter storm system already beginning, the precipitation has been mainly rain across the area. Temperatures are above freezing, and snow might not begin until about 6:00 p.m. That's the good news for rush hour commuters.
The bad news is that a Winter Storm Warning could still be activated later today or this evening. The area of heaviest snow could still shift south toward Interstate 88. The timing of freezing temperatures and heavy precipitation are a major factor. One thing is certain: The snow will be heavy and wet "Heart Attack Snow."
