Some morning flurries Monday were associated with a quick-moving disturbance aloft that is continuing to chug along quickly enough to allow for afternoon breaks of sunshine and highs near 40. Afternoon conditions will be perfect for continued melting of any lingering snow-covered roads and walkways.
Our next storm is already racing east across the Great Lakes, poised to charge from west to east across New England during the day Tuesday.
Though Tuesday’s storm lacks a deep tropical feed of moisture – this past weekend’s moisture plume has been redirected southward – there is plentiful upper level atmospheric energy that will fuel storm development directly over New England.
In fact, when these intense energetic disturbances move along arctic fronts – the leading edge of arctic air like we have nudging into New England from Eastern Canada Tuesday – they can develop quickly intensifying storms, and Tuesday will be no exception.
The result south of the intensifying storm is a push of warm air, destined to change any light early morning freezing rain and snow showers for interior Southern New England quickly to rain after a few isolated slick spots start the day.
North of the storm, snow will fall heavily. In total, over a foot of snow should fall in Northern New England mountains with nothing at all in Southern New England.
Behind the storm, that nearby arctic air will come pouring in for Wednesday, dropping wind chill values into the teens.
We’re watching another disturbance for Friday, then again early next week in the exclusive Early Warning Weather 10-day forecast.
