Thanks for watching. I'm meteorologist Jacqueline Thomas.
As we head through these next couple of days,
all eyes are on the incoming snowstorm that we're expecting
for Tuesday.
It will bring alert weather to parts of the state
mainly S with just impact to nuisance type weather as
you head further north where we're expecting lower snowfall amounts.
So on Tuesday, accumulating snowfall expected,
most of it coming during the morning,
midday to early afternoon hours.
The heaviest and highest snowfall totals expected further South in
the state.
Also a chance for some coastal flooding.
Concerns with this storm system as well,
especially that high tide cycle Tuesday afternoon.
As far as storm impacts snow,
a high impact with this one slower travel also expected
as we see that snow stick through the morning hours.
That morning commute will likely feature slower travel conditions,
some Messier roads, and even through Tuesday afternoon or evening,
there likely will be some slower travel winds,
this time around a lower end impact,
just because the gusts won't be quite as strong as
what we've seen with some other storms.
As we head through the day on Tuesday,
winds will be generally 25 to
30 mph for gusts. And then behind this storm is
when we actually see the stronger gusts move in,
but a medium impact with that coastal flooding concern around
that high tide cycle.
For sure as we head through these next couple of
days,
here's the futurecast Monday stays pretty quiet.
We'll see increasing clouds Monday night,
and then the snow doesn't really begin until those late
night hours,
Those wee early morning hours on Tuesday after midnight,
say two, 3:00 in the morning,
That'll really be when snow starts to stick,
especially southwest in the state as this moves in from
southwest to northeast overnight.
And then Tuesday morning, likely steady snow coming down,
especially the southern half of New Hampshire.
And you'll notice where some of these heavier snowfall bands
are and these darker shades of blue,
certainly down across southern parts of New England and Massachusetts
and then across far Southern New Hampshire,
mainly Manchester S That's where the higher snowfall rates are
expected,
the heavier snowfall is expected.
And you'll notice how quickly the snowfall intensity lessens as
you head further north.
That means that we're not expecting as much snow the
further north you go,
and therefore not as much of an impact,
but where you head South and you get some of
these heavier snowfall bands,
that's where you'll see the potential for several inches of
snow and certainly higher impacts.
Still a little bit of uncertainty regarding just exactly how
far north and just where the edge of this heavier
snowfall band sets up across Southern New Hampshire.
Either way, this all pulls out as we head through
late Tuesday afternoon and evening with quieter conditions but colder
conditions expected for Wednesday.
As far as snowfall amounts are concerned,
this is what we're looking at.
Areas in that pink color across Southern New Hampshire.
That's where you have the best chance of seeing 6
inches or more,
and perhaps even a couple of double digit totals from
this snowstorm,
Especially as you head South towards Nashua,
Salem. The further South you go,
closer to Massachusetts, that's where you'll likely see the higher
snowfall.
And then a quick drop off in those totals as
you head north Concord 3 to 6 inches back up
towards the Lakes region closer to 3 inches and then
123 from Lebanon to Plymouth up towards Conway with just
a coating to an inch pretty much north of Plymouth.
And as you head up towards the mountains and then
even north of Berlin,
you could see really next to nothing as far as
accumulation is concerned with this particular storm,
coastal impacts, the coastal flood threat again will be highest
as we head through that Tuesday afternoon high tide cycle.
That is when we could see the high tide height
reaching close to 12 feet,
which becomes moderate flood stage at the coast.
Even Monday late in the day you could reach minor
flood stage at the seacoast with that high tide.
But Tuesday and then even into Wednesday morning,
moderate to minor flood levels of that tide are possible.
So got to watch out for that right at the
coast.
The winds as we head through Tuesday again,
gusts 25 to 30 mph possible,
the highest gusts likely right at the shore.
And then as we head behind the system Wednesday,
that's when we could actually see some stronger winds move
through with gusts pushing 40 to even
45 mph in parts of the state.
So the seven day forecast alert weather for Southern New
Hampshire on Tuesday as that storm comes through,
bringing snow and then colder Wednesday,
Thursday. Highs in the low 30s.
It'll feel much colder thanks to those stronger winds,
but it will be drier overall before another chance for
some snow showers as we head towards the end of
the week.
