BOSTON – We are at the moment in a Subsequent Temperature Inform for a lengthy-duration, multi-faceted winter storm which will arrive Sunday night and previous by means of Monday night.
Considerably like the past storms, this one will function rain for some, snow for others, and changeable conditions through the 24+ hrs of precipitation.
Maybe the toughest connect with on Monday will be regardless of whether to cancel university. Most of southern New England will wake up to rain Monday morning.
But, as colder air arrives, the rain will alter to a large, damp snow in the course of the working day Monday. This could make for treacherous travel ailments throughout the afternoon and night.
Lastly, we also have some concerns with wind, coastal flooding, and electricity outages on Monday.
Whilst the winds is not going to be almost as solid as some of our common nor’easters, when put together with the pounds of large snow on the trees and electrical power strains, there could be just ample wind to generate some power outages.
A Wintertime Storm Warning is in effect for the northern Worcester county and northern Middlesex county and the areas shaded in pink exactly where the most important precipitation variety will likely be a hefty, soaked snow. Travel could be complicated on untreated surfaces.
A Winter Climate Advisory is in influence for the city of Boston and the parts shaded in purple. Lesser amounts of snow are predicted, but system on slippery road disorders, particularly midday Monday and into the Monday night commute.
A rain/snow blend will continue on Sunday night time throughout the Bay Condition with colder circumstances largely north of the Pike foremost to snow, whilst milder problems to the southeast top to rain.
In just a several hours, ahead of midnight, plenty of delicate air will operate in to press the rain/snow line northward closer to New Hampshire. The only places in southern New England that will see any snow right away are the Berkshires and maybe, at times, the northern Worcester Hills. In essence, for the rest of the spot, this will just be a rainy evening.
When you wake up Monday morning, very same deal – raining just about just about everywhere, most likely some damp snow mixing in at the greatest elevations in northern Worcester County.
This will make for a really tricky decision for educational facilities. Do you close centered on the forecast for a alter to snow? I imagine it is dependent mainly on a handful of vital variables.
What time will the alter take place? How considerably snow do we hope to accumulate on Monday? Eventually, what is the risk of ability outages? Let’s see if we can remedy some of people issues.
Approximate changeover from rain to snow on Monday:
10 a.m.: Northern Worcester County, northwest Middlesex County (Towns these types of as: Fitchburg, Nashua, Townsend).
Midday: Northwestern parts of Interstate 495: (Towns these as: Lowell, Lawrence, Amesbury), effectively all of northern Massachusetts and southern New Hampshire.
2 p.m.: By this time it will be snowing in all regions alongside and north of the Mass PIke including Worcester and Boston. Also expect the snow to have attained all of Norfolk County and northern sections of Bristol and Plymouth counties.
4 p.m.: Snowing in all of southern New England outdoors of the Outer Cape and Nantucket.
Luckily, the snow will commence to taper off in the evening from west to east. It must conclude in areas of central Mass. all-around 6-8 p.m. and in jap Mass. amongst 8-10 p.m.
The snow quantities are not an straightforward call. A great deal like the last storm, the temperatures will be extremely close to 32 degrees for a massive element of the decrease atmosphere and surface temperatures in a lot of spots will be a little previously mentioned freezing Monday afternoon while it is snowing. So, it will take a reasonably significant fee to get any sort of significant accumulation. It does surface as although it will snow extended plenty of and major more than enough for some accumulation to come about in jap Mass. Monday afternoon and evening.
Coating to 1 inch: Down by the South Coastline and South Shore (all coming later on Monday). We need to have to check out this region intently, as a burst of snow in the afternoon may perhaps guide up to a few of inches on unpaved surfaces.
1 to 3 inches: Mainly East of I-495 to the north shore to Boston and elements of interior Southeastern Mass. (All coming Monday afternoon and night).
3 to 6 inches: All over and West of I-495 From northern Essex County into northwestern Middlesex County and a greater part of Worcester County into New Hampshire and as significantly south as northern CT. (generally coming Monday midday by evening).
6 to 10 inches+: Northern Worcester County, the Berkshires and southwest New Hampshire. The 10+ would only be in the highest elevations the place precipitation stays all snow (storm total, some overnight, some in the course of Monday).
We do have an included wind issue with this storm contrary to the previous few. We expect north-northeast gusts in between 20-40 MPH through Monday morning/midday.
Then, as the storm begins to wrap up and exit, the winds will shift to the north-northwest, gusting 20-40 MPH during Monday afternoon and night.
Yet again, put together with a very heavy, moist snowfall, this could be just ample wind to result in some downed limbs and ability lines.
Also, provided that our tides are astronomically superior on Monday, there will probable be some minor coastal flooding during the midday substantial tide cycle. The usually susceptible shore roadways may briefly be washed out.
What is actually Up coming
No relaxation for the weary! There is a further storm headed our way later on on Wednesday!
This 1 appears like it may begin snow Wednesday night and transform to rain overnight, long lasting effectively into Thursday.
Active 7 days in the weather office. More on that storm to occur.
