First Call for Light Snows Tuesday; Larger Potential Looms Next Weekend
Manageable Snows Overnight Tuesday
Synoptic Overview
This weekend's rain storm is becoming stuck underneath the negative NAO block, which will allow it to act as a polar vortex lobe. A modest piece of vorticity (energy) will rotate around the southern periphery of this system and trigger a round of light to potentially moderate snowfall overnight Tuesday.
Anticipated Storm Evolution:
Light snow or flurries should break out over southern portions of the region during the afternoon into the early evening.
And become occasionally moderate overnight Tuesday night across the southeastern half of Southern New England.
Before beginning to taper off after midnight and during the predawn hours of early Wednesday morning.
And ending prior to the Wednesday AM commute.
While it the Wednesday AM commute should be manageable, it would be wise to afford oneself some extra time.
FIRST CALL:
Looking Ahead to Potential Weekend Storm
After the period of snowfall Tuesday night passes, all eyes shift to late next week into the weekend, as the PV lobe splits and a 50/50 low and potential east coast storm.
