When I saw the new run of the computer models and the European and the GFS and the NAM (all names for our models) pointed to another plowable to major snowstorm my heart kinda sank. I guess we can consider this a 24 hour reprieve between big systems. As if that wasn’t fun enough, more snow is possible Tuesday from a clipper type system. That could bring several inches ahead of the milder air for later next week.

Not much will change to the forecast overnight and I will make a new update in the morning. We all know what these storms bring at this point. There are some unique aspects to every storm. This is going to be a quick hitting storm which happens in about 12 hours between noon and midnight Saturday.

The snow will be heaviest from 4PM until 10PM and at times there could be blizzard like conditions over parts of Cape Cod where winds will be strong and visibility is lowered to under ¼ mile in the heavy snow. To the north of Plymouth including Boston, snow will accumulate several inches and Boston itself will likely see about twice as much snow from the storm Saturday night as the one yesterday.

This is a very dynamic situation and as the storm evolves it could change the snowfall totals predicted. I recommend checking back tomorrow to see what new information overnight has done to my forecast.

The snow will be lighter and fluffier that it was in the last storm, but over Cape Cod it will start heavy and wet and may be mixed with rain. If the system starts as all snow over parts of the Cape a foot of snow is possible. Some isolated areas could see even more snow than that if the storm tracks a bit slower or gets even stronger. This will be a major storm for Cape Cod where 10 inches or more of snow isn’t something that happens very often.

Over Nantucket and Martha's Vineyard the snow will be wetter and heavier and there can be some rain at times. Amounts there will be in the 5-10 inch range. If the entire storm shifts further east, the cold air will keep these islands colder and you will see more snow.

I'll have updates later this evening and throughout this storm on Twitter @growingwisdom.

The storm could move a bit faster and then amounts would be less than I am forecasting. Notice how little snow there is just 30 miles west of Boston. A difference in that many miles of the track of the storm changes the totals significantly in eastern Massachusetts.

Winds will be strong with the storm and there could again be scattered power outages from this quick hitting nor’easter. Cold weather returns behind the system for two days. Highs Sunday and Monday only reach the 20s.

Tuesday, we have the next storm with more snow or snow and rain. I’ll have details over the weekend. It does turn milder after that and I promise highs reach at least the 40s by the end of the week.

Winter isn't over
There are many signs pointing to more cold air to end February and being March. Enjoy whatever melting we see later next week for it's not going to last.
