As of 3:30 on Thursday afternoon, the NOAA folks are suddenly singing a different tune. The track of the storm is now supposed to be more toward the east, which means the snow totals will be much lower than originally expected. The good news is that the forecasters still think the heaviest snow will fall over the southern Green Mountains and the Berkshires, with now only 5-12" in the forecast area. Also, the Winter Storm Warning is now in effect starting at midnight, not 6 p.m. as it was previously.
These changes don't seem to change the fact that we're still in for a major snow event for this time of the year. Unfortunately, we do have to downgrade our prediction and give a more rational accounting of the storm. Look at the radar--you'll see the moisture just isn't there yet. Sometimes the radar doesn't lie.
