    Another amazing day of spring-like warmth is unfolding across New England Tuesday that will not only boost temperatures to 60 degrees again for many in Southern New England, but also gives revelers an amazing day to celebrate the World Champion New England Patriots in Downtown Boston.

    The warmest of any Patriots celebratory parade – and we have many to compare to now – the route will see clouds parting for increasing sun and temperatures close to 60 for most of the route. This is comparable, if not perhaps even a bit warmer, than the Red Sox victory parade in the fall. Except, it’s February now!

    A dose of reality is already entering Northern New England, however, in the form of a cold front. A wind shift is set to blow from the northwest Tuesday evening and will start the flow of new, colder air.

    This will be dropping Tuesday night, when low temperatures will be at the teens north and 20s south, and holding highs in the 30s Wednesday. This cold air comes just ahead of our next weak storm center, slated for Wednesday night into Thursday.

    The upcoming storm prompted our NBC10 Boston and NECN First Alert Weather Team to declare a First Alert for impactful weather. A period of freezing rain and sleet is expected to develop Wednesday night around or after 10 p.m. and continue into Thursday.

    Cold temperatures will allow precipitation to begin as a period of overnight freezing rain and sleet Wednesday night. This will be making roads slick and will likely continue into early Thursday morning until warmer air slowly transitions most areas to plain rain, with showers continuing Thursday.

    In Northern New England, a period of snow is probable Wednesday night before a change to a wintry mix, with some northern valleys remaining slick well into the day Thursday.

    Milder rain showers are expected Friday, before the cold and dry weekend air precedes a storm that has the potential to deliver accumulating snow to most of Southern New England Monday.

    As always, however, it depends heavily upon the track of the storm. Seasonable temperatures seem likely to round out next week in our exclusive First Alert 10-day forecast.
