Light rain/drizzle should develop towards sundown, with fairly steady rain commencing around late evening into the overnight Monday night/Tuesday from south to north.

On Tuesday, the coastal storm will begin to intensify. A wind-swept, heavy rain will be felt for much of the day and early evening before rain tapers off for Tuesday evening at the coast and in the city.  Elsewhere,  rain should linger north and west of I95 and transition to snow before ending. Moderate coastal flooding will be likely Tuesday and Tuesday night at the coast. Winds could gust as high as 50mph for the city and coast, with 40mph gusts possible further inland.

For Wednesday, we'll remain cloudy. A few quick-hitting rain and snow showers should move through during the day for all areas. Winds will subside, but remain gusty.

While the steadiest, heaviest rainfall will be north of our region on Wednesday,  the overall configuration of the jet stream will not allow the storm to completely move out of the northeast states. Accordingly, our weather will remain unsettled through Friday, with clouds prevailing for much of the period; scattered rain and snow showers will pose a threat of moving through from time to time, particularly during the day, until the stubborn low pressure is able to weaken and pull further north sometime on Friday.

Thereafter, our weather will improve even more by the weekend, with temps rebounding into the mid and upper 40s and rainfall chances finally diminishing.

In the long term, a cold and stormy regime should continue throughout the rest of the month, with transient spells of above-normal temps. After the 20th, there are strong signs that the overall pattern will begin to "lock in" to winter,  markedly raising the prospects for bouts of sustained cold and disruptive snows during the busy holiday season.
