Resending the briefing package to include the subject header.
Good afternoon,
Here is our latest thinking on the next phase of the winter storm.
Watches/Warnings/Advisories:
NEW:
1) Winter Storm Warnings expanded to include coastal Essex, Suffolk, Norfolk and Plymouth counties.
2) Winter Weather Advisory issued for Cape Cod
3) Wind Storm Warnings converted to Advisories for western and northern MA west of I-495
What we expect:
Tonight into Tuesday morning
- Rain changing to snow across eastern MA through this evening with changeover occurring on Cape Cod toward daybreak
- Bands of heavy snow possible across much of eastern MA, especially from 4-10 am. Localized snowfall rates of 1-2"/hour possible
- Significant impacts to morning commute across eastern MA
Strong Winds:
- Wind gusts to 40 mph expected along coastal areas, with the highest gusts over Cape Ann, outer Cape Cod, and the coastal waters off eastern MA.
Snow Accumulations:
- Additional accumulations after 7 pm tonight through Tuesday morning...
- Generally 2-4 inches across much of the region, but up to 4-8 inches possible across eastern MA, especially from Boston north through Essex county and the Merrimack Valley.
Confidence :
- Moderate confidence in additional snowfall of 4 inches for eastern MA. Lower risk for up to 8 inches, especially north of Boston.
- If storm tracks a bit further east than expected, lower snowfall amounts would be realized for eastern MA with max snowfall around 4 inches.
- If storm tracks further west, 4-8 inches would impact a larger portion of eastern MA and possibly into northern RI, with locally higher amounts north of Boston.
