TUESDAY UPDATE

Issued Sunday Evening

Storm moves in tomorrow. There is more uncertainty than confidence with this one and it is just nerve-wracking. One model says this, another says that, a third is completely different, and the fourth is out in left field. So what is going to happen? Well, its going to snow, that is a given fact. How much and where? Like throwing darts at a wall right now. Quite honestly, I don’t know what to tell you. Pick a model that looks cool and slap that down and we will see. Because of this, I am not issuing another accumulation map right now. I will instead share the different top 4 models with you.

The NAM. North American Mesoscale. Historically, to me, this has been the most accurate, and was the most accurate for the last storm.

EURO, also known as the European Center for Medium-range Weather Forecasts (ECMWF).

The GFS, which is the Global Forecast System. This is known as the “American Model”.

Last but not least, the National Weather Service Blend. This one takes a sample from different forecast models to come up with an average. This is the one I have been basing a lot of me predictions on for this storm system.

So what will happen is anyone’s best guess right now, which is why you will see all sorts of numbers all depending upon what model they choose the use. What we can roughly estimate is the timing.

TIMING-
Storm rolls in around 8-9pm Monday night from the southeast and heads northwest. By 11pm, it is hitting Worcester up to Nashua and down to Providence. By about midnight, snow will be making its way into the Boston area right up to the NH and ME coast. 3am Tuesday areas like Littleton, NH and Fryeburg, ME start to see the flakes. By 6am, Rangeley and Skowhegan, Maine are into it.
Things begin to taper off from the southeast around 1pm Tuesday, and progress northwest through the day.
