Storm Update: Snow odds Saturday-Sunday

The computer models continue to advertise a more significant snow event for Southern New England Saturday afternoon and night. We’ve been telling you all week (longer if you’re a Pro member) that it was going to be a close call with a Nor’easter this weekend, and now it looks like the storm will be closer to a Nor’easter than a non event.

Snow will break out around midday and quickly become steady during the afternoon. There is some concern for mixed precip. or rain at the immediate coast at the start of the storm. The precip. will likely start as rain on the Cape/Islands, but a change to snow is likely Saturday evening.

The graphics below include the traditional snow forecast map, and some probability graphics displaying the odds of reaching a certain amount in the Providence area, and the most likely final snow amounts in the Providence area. Since this is a storm that will bring a similar amount of snow to the RI and most of SE MA, these odds are similar for places like Newport, New Bedford, Taunton, and even Boston.

In the first graphic, notice how likely it is that the Providence area will receive at least 3-4″ of snow. The odds diminish gradually, indicating that there is some decent potential for a 6-9″ snow event if the storm is a bit stronger than forecast.
