PM WEATHER UPDATE: Blizzard Watch For RI, 1-2 Feet of Snow
Wednesday, February 06, 2013
This latest weather data and model runs seem to reconfirm my earlier expectations. A major winter storm is on tap for Southeastern New England … one that if it remains all snow, is likely to exceed a foot in accumulation and could approach double that at some locations.
When will it hit RI?
The storm center will spin up off the Mid-Atlantic coast Thursday night with snow likely beginning here around or shortly before daybreak on Friday. Indications are that the snow will come down heavy through the afternoon and night on Friday, then gradually taper and end on Saturday. After seeing today’s data, I am less inclined to think there will be a significant change to sleet and/or rain in the middle of the storm except right along the Rhode Island south coast and over the Cape and Islands and even there the storm could stay all snow. Winds likely will gust over 50mph and that should cause considerable drifting.
Again, I caution, that with the beginning of the storm still over a day and a half away and with the storm not yet a formed reality, as we are all too aware there could be significant forecast changes. My main concern continues to be that snow to sleet and rain change that would significantly cut into snow totals. As I indicated earlier, it seems less likely now but is something that needs to be watched carefully. I will continue to bring you updates as the storm gets closer and as the situation warrants.
