A strong energetic disturbance will cross New England on Saturday. The intense energy associated with this disturbance will have limited moisture to work with, but will produce snow showers and squalls akin to a summertime round of showers and thunderstorms - heavy in some locales, lighter and others, and producing varied amounts of precipitation from one location to another. When all is said and done, some key points:
- A southwest wind likely produces some snow showers Sunday morning in Southeast MA, enhanced by the ocean
- As those early southeast snow showers end, the main disturbance approaches from the west, inducing a strong south-southwest wind with gusts to 45 mph.
- The south-southwest wind carries warmer air into New England, with highs in the 20s west/north, and 30s east.
- Snow showers and squalls arrive Saturday afternoon and evening, west to east.
- Like summertime showers/storms, the snow showers/squalls will be locally heavy.
- Snow will melt on roads at first (may even start as raindrops Saturday afternoon in Southeast MA) then will freeze on some roads as temperatures fall, creating slippery conditions for some communities Saturday evening.
- Total snowfall amounts indicated below are average amounts for each area, but variations will occur due to the bursting nature of the snow.

So...I'd encourage watching the radar Saturday evening if you'll be out and about!
