Saturday Morning Update
As of 10:30 this morning a strong low pressure system is pulling out to sea east of Nantucket. The next few hours will see the rain end as snow away from the immediate coast and some slick spots could develop. As I write this, snow is mixing with the rain near Route 128.
The image loop below shows how the rain (green) will change to snow (blue) as it all comes to an end. Across the higher terrain where it’s already snowing 1 to 3 inches of snow will be on the ground by mid-afternoon. (see map from last evening),
Friday Night Update
A quick hitting nor’easter is on the way for Saturday with a wet morning and some opportunity for the rain to end as a period of wet snow for the early afternoon. The reason this is called a nor’easter, in spite of it being a rain storm, is because the winds during the storm will come from the northeast or off the ocean.
This storm is moving along a steady pace so I am not expecting any coastal flooding or long lasting high winds from this weather system. The biggest impact will be wet roads for doing errands tomorrow morning. Winds will gust over 40 miles per hour over Cape Cod and the Islands. There could be scattered power outages in these areas with the strong winds.
I circled the storm responsible for our inclement start to the weekend on the map below. Typically in January a low pressure area (L), in this position would bring snow to most of the area. The problem for those of you who want snow is we just don’t have any cold air present. The cold air will arrive next week, but without a storm it won’t matter.
The rain will be a cold rain and as it comes down hard during the morning just before ending there could be a change to snow. This change would occur first over the higher elevations and then perhaps make it to Boston in the final hour of the storm. Because of this chance of snow or even freezing rain, the National Weather Service has issued a winter weather advisory for Saturday morning. These advisories are issues when winter weather will impact an area, but it’s not going to be so bad we have a winter storm warning.
The map below shows how much snow I am expecting. Snow isn’t any issue east of Route 128 and the best chance for a sanding or a plowing would be areas over the Route 2 corridor west of Route 495. Places like Hubbardston for example could need to call out the plows.
Gillette Stadium Forecast
There is a football game tomorrow as well. If you are headed to Foxborough for the Patriots playoff, it will be a rainstorm and the precipitation should be finished in time for tailgating and certainly the game itself. You might see some wet sloppy snowflakes around 10 or 11 a.m. If you get to the stadium closer to kickoff, just expect a chilly wind with temperatures falling through the 30s during the game. The map below (credit:WeatherBell) shows the precip almost entirely gone by 2 p.m.
Timing Of The Storm
The precipitation will be underway before sunrise Saturday. This means travel tomorrow will be slowed by rain or mixed precipitation and snow near the New Hampshire border.
Colder Air Coming
Sunday is another nice day with a blend of clouds and sunshine and once again seasonably cold air. Sunday night a weak storm will cross the Great Lakes and bring a period of snow showers lasting into MLK day. After this system passes, arctic air will infiltrate all of New England and keep temperatures below average for the rest of the week. It’s not impossible this ends up being one of the coldest weeks of the winter, but we won’t know that for sure until late February. Have a great weekend.
