Significant Weather Outlook: Monday, January 19, 2026 10 AM
Weekly Significant Weather Outlook for Southern New England
For the week ahead, looks like very cold temperatures Tuesday and Tuesday night followed by moderating temperatures Wednesday through Thursday. Colder, possibly much colder temperatures appear to be in store for Friday into the weekend as a piece of the polar vortex may break off and move across southern Quebec and far northern New England. Precipitation during the work week looks to be fairly light and spotty. Next weekend remains uncertain. Some global models appear to be setting the stage for a major Southeast USA snowstorm. Other models, primarily the AI versions, would have the storm further north and possibly impacting southern New England.
It’s possible that a series of message blogs will be issued later in the week for potentially severe cold temperatures and/or snow for next weekend. Will assess future trends and go from there.
