Tonight’s wave of low pressure is intensifying a bit more than first thought and as a result, we may end up on the high end of the 2 – 4″ mentioned this morning. There’s a pretty sharp cutoff between snow and slop, and right around the ICC is still a good guess. Accumulations will vary from about 1 – 2″ south of the ICC, 2 – 4″ north of there to about I-70, and 3 – 5″ north of there to the PA line. Western areas and the Parr’s Ridge crew in Carroll county could do a little better than that and Winter Storm Warnings have been issued in those areas. The rest of us are currently under the lesser Winter Weather Advisory. Some light snow is already starting to develop in western areas but I don’t think the accumulating rates will come until after 7 this evening. Snow continues overnight and ends just after sunrise tomorrow.
The second batch of precipitation that was mentioned this morning looks to stay well south of us tomorrow night, but Saturday afternoon and night has the potential to be very icy with temperatures below freezing with sleet and freezing rain. I’ll update that tomorrow.
