There is a strong boundary between very cold air in Canada and record warmth in the eastern United States across far northern New England today.
Along that boundary, we have rain showers near the Canadian border, mixed with snow and ice in northernmost Maine.
With mild and muggy air in southern New England, we may have a tough time burning through the low clouds and fog near the south coast, due to cold ocean temperatures and wind from the south 10-20 mph. For the rest of New England, showers let up for our Tuesday with a few sunny breaks allowing the temperature to get to near 60 degrees.
Although rain is not too heavy, a quarter to three-quarters of an inch, we have a flood watch in effect for the mountains of New England where melting snow will contribute to rapidly rising rivers.
The warmest weather likely occurs tomorrow, with enough sunshine we should hit 70 degrees in spots breaking records for this time of year. Interestingly it was a year ago this week we also got to 70 degrees and broke records.
Last year was on the 24th, this year it's on the 20th and 21st. Last year winter came back with snow a few days later, the same thing could happen this year.
A cold front comes through tomorrow night with temperatures slowly falling through the 40s north and 50s south. Another batch of rain will come through late and overnight. Then we start to dry it out early Thursday.
A weak wave of low pressure on the front may bring a period of light rain or a wintry mix to parts of central and southern New England Thursday afternoon as temperatures cool into the 30s.
After that is a very difficult forecast, as waves of low-pressure will ripple along the boundary between record warm in the southeastern United States and a winter chill in southeastern Canada.
Here in New England, we will likely have off and on rain and/or snow, with freezing rain possible too, especially late Friday and early Saturday and again on Sunday.
Temperatures may range from 20 degrees at the Canadian border to 50 degrees at the South Coast. Obviously, we have a lot of fine-tuning to do to the extended forecast.
