More snow, but not a big storm

As I look at the latest computer models I notice a couple of trends. First, the amount of snow being forecast is down slightly for Boston as compared to the last computer models. When reviewing the models, this trend is a good indication of the final forecast. So I am confident this is not going to be a big storm. However, the outer Cape will likely see a moderate storm.

Right now, I like the idea of a 2-6 inches storm across the state. The 6 inches amounts will be across the South Shore, Cape and Islands. For those of you from about Chatham to Provincetown up 8 inches is a possibility. Boston proper running back through Newton to Framingham and west to Worcester to Pittsfield will average 2-4 inches with some 5 inch amounts. As you get up to the north across the NH border figure about 2-3 inches.

The snow begins around 3-5 a.m. to the southwest and moves eastward reaching Cape Ann by 6-8 a.m. The bulk of the snow falls from mid-morning until early afternoon and is done completely by 7 p.m. There may be some lingering snow showers east of Chatham for a couple of more hours.

I would not cancel plans for Saturday night. The roads will be plowed by then and while there will no doubt be slippery areas, this is not a crippling storm. Those of you to the south of Boston will have several hours of slow driving during the middle part of the storm but that should be the extent of the impact.

The wind map (left) shows that the winds at 30,000 feet are blowing very fast. That is why our storms are coming in rapid succession the next few days. By the way, just because the winds at that level are over 100mph, doesn’t mean it will be windy down here. I am not looking for any issues with wind or tides from this storm.


Sunday will feature a brief reprieve from any storms but there is the chance for a bit of icing Sunday night especially away from the coast. Any icing that occurs will be light but it doesn’t take much to make roads slippery.

By Monday it’s much milder with rain showers. I can see several places hitting 45 or even 50 degrees. So if you like the snow and want to go out and have some fun with the family after the storm better do it fast, because more melting is on the way.
