Spring Storm Update

We're still under a Winter Storm Watch in the Berkshires. Very little has changed to the forecast since yesterday. And because of the relative stability of the forecast, we are starting to think that all parts of Berkshire County will see measurable snow from this event.

Even though the temp will not drop below freezing on Thursday or Friday, there will be enough cold air aloft to convert the precipitation to snow.

East facing slopes in elevations above 1500 feet are expected to see half a foot. The rest of us will be in the 2-4 range. Because of the timing of the storm, the Friday morning commute is likely to be sticky.

The models are still in wide disagreement. The Euro is holding steady with a 3-5" forecast; the two North American models are still bonkers, showing 8-10" in the Berkshires and up to 19" in central Mass. That outcome just seems preposterous, so we are going to favor the Euro for this event.

We're including this North American model (the GFS) in here just for fun. Do not take this model seriously.

Thursday is going to be wet for most of the day. The snow should start to fall after most folks are asleep Thursday night. And we'll know Friday morning whether this storm is a bust or a blockbuster. School officials will have a tough decision to make on Friday, and for some districts that could mean a full snow day.

More tomorrow!
