Area Forecast Discussion
National Weather Service Boston/Norton MA
755 AM EDT Sun Apr 15 2018

.SYNOPSIS...
Quite a chilly day which will be accompanied by periods of
sleet and freezing rain. Low pressure will push across the
region Monday, swinging a front across the region which will
bring rain, locally heavy at times, along with isolated
thunderstorms. Showers will linger into Tuesday across interior
portions of the region. Another low pressure may approach
Thursday, bringing another round of showers. Temperatures will
continue to run below normal early this week, then moderate to
more normal levels later this week.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
745 AM Update...

Weak ridge of high pressure and low level dry air has thus far
been sufficient to keep precipitation to our north. Temperatures
were also slightly higher. Once precipitation arrives,
evaporational cooling should permit temperatures to fall
slightly.

Made major updates to the forecast to slow down the timing of
any precipitation this morning. If anything does fall it will
be in the form of very light precip as temp/dewpoint spread
remains large.

Contemplated canceling portions of the Winter Weather Advisory.
A complication will be the arrival of precipitation later this
afternoon, where sleet and or freezing rain would be possible.
Rather than dropping the advisory, only to maybe put it back in
place later, will wait it out a bit longer. The longer we
remain precipitation free, the less likely we would see wintry
precipitation, particularly across the coastal plain of RI and
SE MA.

Previous Discussion...

* Unseasonably cold day with rain, sleet and pockets of freezing
  rain across much of SNE *

Quiet a change of airmass compared to 24 hours ago. High
pressure to the north will continue to push cooler temps into
the region today. In fact, 925 mb temp will fall to about 2 STD
below normal, quite an anomolous airmass. Since highs will reach
in the upper 20s to mid 30s it appears that all of the climate
sites could break their low max temps.

Precipitation chances have been tricky for today. Boundary well
to the south of the region with southerly winds in the mid-
levels will indicate some overrunning precip. However, still a
strong temp/dewpoint spread across the area this morning. BUFKIT
soundings also show that the profile will take its time to
moisten and with PWAT values actually weakening today feel that
on and off showers or just spotty precip will occur.

Since temperatures continue to fall, p-types will vary across
the area. Light rain will occur across areas where the
temperatures are above 32F. However as we go through the day and
temps fall, strong subfreezing layer will establish itself
below 900mb. This will help transition any precip to sleet
despite the strong warm layer at 800mb. One issue to watch is
the lack of ice in the snow growth region, so may have to
contend with drizzle, freezing drizzle or even snizzle. Overall,
appears that a mix bag of wintry precip will occur today, but
more in the way of on and off showers or pockets of precip.

Finally, winds out of the northeast will remain gusty. Strong
enough jet at 925mb and with mixing up to that level expect wind
gusts near 25-35 MPH.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM MONDAY/...
* Wintry Mix will impact the region Tonight

Tonight...

Better chance for precipitation to occur will be this evening
and into tonight. Ridge axis will begin to move offshore as
strong surface low will approach the region from the west. PWAT
values will be on the increase reaching above 1.3 inches (2-3
STD above normal). This combined with strong 850mb jet will help
bring widespread precipitation to the region.

Temperature tonight will be cold to start so any precip that
forms will once again be in the freezing rain/sleet mix. However
surface temperatures will be on the rise thanks to WAA. This
will help transition any wintry precip to more of a rain event
towards dawn. However, the high terrain may take their time to
flip over resulting in wintry precip lingering into the morning.
This could impact the beginning of the morning commute. The WAA
will also help erode the subfreezing layer below 900mb, so
p-types may switch more to freezing rain than sleet before
flipping over to rain. The combination of the high moisture
airmass and good dynamics will bring more QPF to the region.
Thus we could see a light glaze of ice across most of southern
New England with near 0.1-0.25 inches of ice accretion across
the high terrain. Have adjusted the winter weather adv to last
into tonight to account for the potential for ice. This could
result in slippery conditions across elevated areas.

Aside for the temperatures and precip, gusty winds will also be
of concern. Anomolous LLJ at 925mb will increase to 40 kts
towards the morning. Mixing does appear to be somewhat limited,
but with pressure dropping ahead of the surface low and some
heavy precip moving through, we could tap into the jet resulting
in gusts closer to 40 MPH. One area to really watch is
downsloping from the Worcester Hills. A Wind Advisory may be
needed.

&&

.LONG TERM /MONDAY THROUGH SATURDAY/...
Overview...

15/00Z guidance remains in rather good agreement with the
synoptic pattern into Wednesday. Thereafter, differences arise
in their handling of a potent shortwave over the northern
plains, which will have implications on our forecast later this
week. Have above normal confidence in the forecast through
Tuesday, then a moderate confidence in the forecast for Wednesday
and beyond.

Details...

Monday through Wednesday...
Cutoff mid level low will slowly move over the Great Lakes
Monday night, reaching the Maritimes sometime Wednesday. This
will generally keep our region within a synoptic cyclonic flow
aloft. This would support at least a slight risk for periods of
wet weather, depending on available moisture, as well as near to
slightly below normal temperatures.

Main period of wet weather will be Monday into Monday evening. A
triple point low pressure is still expected to move across
southern New England during this time. This will help to enhance
low level convergence, and make rainfall processes more
efficient. Lots of moisture expected to be in place, with
precipitable water values 2-3 standard deviations above normal.

Instability remains marginal, but also persistent, for several
model cycles, now. Maintained the mention of isolated
thunderstorms for Monday.

Significant anomalies with the 925 mb wind, both for advecting
moisture north, as well as colder air from the North Atlantic.
Besides the potential for strong gusts towards the east coast,
thinking temperatures will also struggle to rise much Monday
morning. High temperature MOnday may be later in the day than
usual. Will need to consider a Wind Advisory with later
forecasts. Thinking it is rather marginal at this point. Will
let the next shift get another look.

Drier air in 850-700 mb layer punches into our region from the
SW-NE behind the triple point low and a cold front Monday night.
This should at least cause any remaining rain to taper off for
a time.

As this low lingers across southern Quebec Tuesday-Wednesday,
could see some patchy showers redevelop during the daylight
hours, especially across northern MA. Mid level moisture will
also keep clouds across much of region through part of Tuesday
night.

Anticipate mainly dry conditions on Wednesday, though some
diurnal showers may still develop across the E slopes of the
Berkshires.

Wednesday night through Saturday...
Another fast moving mid level shortwave approaches, along with a
surface low pressure. Timing and track are still the big
questions. Model solutions are converging, but still some wiggle
room in their solutions. At this time, thinking the window for
the greatest risk of showers is Wednesday night into Thursday,
but this could change. Also a possibility showers linger into
Friday, with a mid level trough still to move past our region.
Lower confidence forecast for this timeframe.
