I have journeyed outside for the first time this morning and the snow is accumulating fast. I now expect something like 5-9″ here along the mainland coast with pure rain along the coast south of Portland. I will continue to monitor the forecast as the complex patterns above our heads keep arguing over weather it should be a rain storm or a snow storm.
As we get the last update for tonight I have seen that the storm has relocated its center to over lake ontario moving ESE into NY and PA. All other forecasts remain the same. As of 9:30 a few showers have crossed the border into ME.
Stay tuned, I will be back in the morning with more info.
As of 8:30 the main precipitation shield has moved into NH and some heavy pockets are mixing in. All ETAs for precipitation remain the same except for the MA forecasts.
More brand new forecasts… As of 7:10 the cold air is winning the battle and very little changeover is expected. As a result I will update my forecast amount of snow to 2-4″ along the coast south of Portland, 6-10″ along the mainland coast between Portland and Bar Harbor, 3-5 along the coast from Bar Harbor to Eastport. Snow amounts will range from only a dusting in Aroostook county to 8-12 in the foothills to 6-10 in the westernmost mountains to 5-8 in inland York county. Here are the updated ETAs of the snow: Providence RI about 8:00, Worechester MA about 8:00, Boston MA about 8:20, Manchester NH about 8:30, Kittery ME about 9:00, Portland ME about 9:30, and Yarmouth ME about 9:45.
Wind predictions have risin to sustained @35mph with gusts @45-50mph.
The main precipitation shield is approaching Hartford CT and will continue to overspread the NE area this evening. With a slightly more westerly track there will be more changeover along the southern coast. As we have a greater changeover potential I will adjust my snowfall predictions for the coast to 4-8″ with 7-11″ inland. Wind forecasts remain the same. The precipitation will arrive in Boston MA at approximately 8:00, at Springfield MA at approximately 7:15, Manchester NH at approximately 8:20, at Kittery ME at approximately 9:00, Portland ME at approximately 9:30, and Yarmouth ME at approximately 9:45. All precipitation will end late Wednesday afternoon with clear skies for turkey day.
The center of this Rapidly strengthening and rapidly moving storm is now located near Indianapolis with a pressure of 994 millibars. As I look at the radar I will have to adjust my estimated time of precipitation arrival for the three cites I have been featuring. These are Yarmouth ME, Boston MA, and Hartford CT. If your town/city is not on here feel free to post a comment with your town/city and I will try my best to make a forecast for you. For these 3 cities these are the times for rain/snow arrival: Yarmouth 8:30, Boston 6:00, and Hartford 3:30. I will expand this list as time goes on. Snow and wind predictions remain the same.
Surface pressures are dropping to near 990 millibars 130 miles SE of St louis signaling that this is a rapidly developing system that has a pronounced spin and a good moisture supply. Snow forecasts have gone up slightly to 6-10″ at the coast and 9-15″ inland. Winds will be sustained at 25-30 mph with gusts over 35 mph.
This storm is REALLY getting its act together and we now have a rapidly strengthening 1000 millibar low centered about 130 miles SE of St louis. All previous predictions remain the same.
Rain has overspread new york city and is expected to arrive here in yarmouth maine at around 8:30 pm EST. Rain will arrive in boston around 6:00 pm EST and hartford around 2:25. Snow forecasts still hold at 5-10″ at the coast and 8-14″ inland.
