It is not 'The Polar Vortex', just something like it - that is spinning through New England today.
One of the top five cold air masses of the entire winter is here for 24 hours.
High temperatures today, under partly to mostly sunny skies, are near 10° north, to 20° south. A wind chill advisory is in effect for our hills where gusts of 30 to 40 mph are likely right through sunset and overnight.
U.S. & World
We should also mention that northern Vermont started quite snowy this morning so there are some icy roads around too.
Under a bright 'Worm Moon' this evening and overnight, the temperature will hold in the single numbers north to near 10° for low temperatures south.
High pressure from Canada comes right over New England Sunday, that means plenty of sunshine and decreasing wind. High temperature Sunday close to 32° south and in the 20s north. Wind from the northwest diminishing to 10 to 15 mph by afternoon.
A warm front approaches on Monday with clouds increasing during the afternoon, and a high temperature close to 40°.
Strong low-pressure passes well north of New England on Tuesday, that puts us on the warmer side of the front. It also brings in a period of rain or showers during the day, high temperature near 50° and a little bit higher.
A cold front passes from west to east Tuesday night, that may cause rain to change to snow before ending in our mountains.
Otherwise we are looking at increasing sunshine for Wednesday with the high temperature in the low 50s south, 40s north.
Colder air comes in Wednesday night setting the stage for a dry and seasonable Thursday, with sunshine and high temperatures in the lower 40s.
Another fast-moving low-pressure system from Canada will sweep across southern New England on Friday with a chance for light rain or snow. High temperature on Friday close to 40°.
Next weekend is a major forecast challenge, as another batch of bitter cold air moves into southeastern Canada, and very warm air tries to push north from the south eastern United States. This puts New England right in the battle zone.
Saturday is likely cold and dry, in the 30s to low 40s. Rain and/or snow likely develops by later Sunday and continuing into Monday.
Details on that storm will have to be worked out as we get closer. March is known for some pretty intense weather, so we will not let our guard down.
