A beautiful weekend – but quite cold – will be followed by a cloudy several days.
Low temperatures will remain in single figures again this morning in the south-east of England, becoming the first single-digit days of 30 January and 31 January 2019.
But at least the wind relaxes as we warm up to 20 degrees south of New England this afternoon.
It is very sunny, except for the northern mountains, where we have clouds and clouds, and outside Cape Cod also with clouds and clouds.
Tonight, the high pressure moves over us, which makes for a big, beautiful, bright moon, and the planets and stars should look bright with a clean, dry air mass.
Once again you want to get dressed if you go outdoors for a walk, with temperatures dropping to single digits south and well below zero north for Sunday morning.
Sunday still looks great, with lots of sun and light wind. High temperatures will reach teenagers in the north and 20 years in the south, with rising clouds in the afternoon.
The storm system that escaped 8 meters of snow at Mount Mammoth in California crosses the nation and will be on our doorstep on Monday morning.
During that time it will snow heavily from Philadelphia to New York, with a moderate to heavy snow wall that relaxes from south to north in southern New England.
We probably get a few inches of snow in the first few hours before we change to rain along the coast near Cape Cod.
For most of central and southern New England, it looks like a strong snow band eight to 10 hours later Monday through early Tuesday, so it’s probably 8-10 inches of snow – for an early gross estimate.
The low pressure will move from Pennsylvania, then develop south of Long Island and follow slowly to near Nantucket.
A low upper level will lock above the head, with several low-pressure surface systems running from south to north across the Gulf of Maine. That means heavy snow bands, with rain on the coast on Tuesday and into the evening.
The east and northeast coast will blow over 50 miles per hour Monday night and first thing Tuesday. There is a chance of a lighter wind from the south from Boston to Cape Cod on Tuesday, with temperatures that will jump to almost 40 degrees and the snow will change in a drop.
Otherwise, further inland, snowstorms will continue on Tuesday, with the heaviest accumulation at this time in the Vermont, New Hampshire and Maine mountains.
There may be a hole in the middle of rainfall, with smaller amounts in southern Vermont, western Massachusetts and western New Hampshire. But for much of New England we could get 10-20 inches of snow – where all the snow stays.
The wind will return from the north on Tuesday evening, with probably icy conditions that will return to the southern and eastern coastline. Wednesday is probably a cold gray day, before a little sun on Thursday. On Thursday night, a warm front will bring a mixture of rain and snow, followed by heavy warming at the end of the week, with heavy rain showers as we head into next weekend.
It is a very busy 10 day forecast for the first alert.
