Area Forecast Discussion
National Weather Service Boston/Norton MA
202 PM EDT Tue Apr 7 2020

.SYNOPSIS...
High pressure remains in control Tuesday with morning clouds giving
way to afternoon sunshine, spring-like temperatures and a modest NW
breeze. Later Tuesday night, a warm front will spread a period of
light rains across most of southern New England. A fast moving low
will develop along that warm front and bring a period of rain
through Wednesday. Another system moves in Thursday bringing more
rain and scattered thunderstorms. Scattered shower activity is
possible Thursday night through Friday. Drier weather for the
weekend before our next wet weather system early next week.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
145 PM Update:

Did make some small tweaks to winds and temperatures, but
overall these changes were fairly minor.

Overall a nice early-afternoon with lots of sun and temperatures
well into the 50s to lower-mid 60s. Still looking for highs in
the mid 60s for most (even some upper 60s towards the Hartford-
Windsor Locks area); except upper 50s near the coasts. Wind
observations from buoy 44013 and at Marshfield indicate sea-
breeze is near or just onshore the eastern MA coast (east of
Boston). May take until the mid- late afternoon hrs before winds
begin to flip to ESE towards the coast.

With full sun, mixing of drier air as the PBL deepens to about
700 mb will cause relative humidities to fall into the 20s
percent in the interior, with west winds that may gust into the
20-25 mph range at times. SPS for elevated fire weather
potential in effect thru 6 PM. See the Fire Weather Section for
more details specific to the fire weather situation.

Previous Discussion...

Today ...

Another very nice day ahead with spring like temperatures and dry
weather. This is courtesy of NW flow aloft. Short wave energy
crossing the region this morning will result in mid and high clouds
impacting the area. However as this jet energy exits mid/high clouds
will move offshore later this morning and give way to mostly sunny
conditions this afternoon across the entire region.

Seasonable temperatures aloft, about 0C at 850 mb. However model
soundings indicate boundary layer extending up to about 750 mb this
afternoon, courtesy of NW flow aloft. This will result in
temperatures overachieving with highs in the low to mid 60s, even a
few spots possible into the upper 60s given downslope with NW winds
10-15 mph but gusting 20-25 mph at times. Despite a weak pressure
gradient this deep boundary layer with modest NW winds thru the
column will also preclude seabreeze development so just as warm into
Boston and Providence as interior locations and probably all the way
to the Cape Cod Canal. The outer Cape and Islands likely have a
cooling SW wind so cooler conditions there. Elsewhere NW winds
combined with boundary layer extending up to 750 mb will result in
drier air aloft mixing to the surface, so expecting RH values to
drop considerably this afternoon.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM WEDNESDAY/...
Tonight ...

Weak pressure gradient, mostly clear conditions and cooling boundary
layer after sunset should promote temps to fall quickly during the
evening hours. However second half of the night clouds will increase
as short wave trough and associated surface low approach in the NW
flow aloft. Rain then likely overspreads the area 06z-12z from west
to east. Models have trended colder especially the 00z NAM with
column potentially cold enough to support a period of wet snow
around 12z across the high terrain of northern MA and possibly into
northwest Middlesex county. Given how dry the antecedent airmass is
across the region today into tonight, evaporational cooling maybe
sufficient for a period of wet snow. NAM and other HREF members
indicate potential period of wet snow. In addition there could be a
period of heavier precip toward 12z in response to moderate to
strong deformation axis forming as 850 mb low tracks across the
area. Will have to watch how later model runs trend regarding
thermal profiles and precip intensity. If heavier precip doesn't
materialize or shifts farther south away from the high terrain, then
any snow is less likely.

Wednesday ...

Periods of rain likely in the morning along with a risk of some wet
snow across higher terrain of MA including Worcester per
aforementioned above. Drying trend in the afternoon as frontal wave
departs offshore. Although light cool NE flow likely precludes much
if any afternoon sunshine, best chance late in the day. Thus mostly
cloudy and cool with highs only 45-50, low 50s CT river valley.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/...
* Widespread rain Thursday with scattered thunderstorms

* Lighter rain and high elevation snow on Friday with a few rumbles
  of thunder possible

* Potential for minor coastal flooding Wednesday to Friday around
  high tide across the east coast of MA and Nantucket.  See the
  Tides and Coastal Flooding section below for more details.

* Temperatures running near to below normal through Saturday then a
  warm up

Details...

Wednesday night...

High pressure ridge briefly takes control Wednesday night keeping
things dry and allowing for partial clearing skies early on.
However, low level moisture fills back in toward midnight and
beyond, so low level cloudcover will be on the increase. This should
help keep temperatures in the upper 30s. High astronomical tides
will contribute to a chance for some splashover or minor coastal
flooding issues along the east coast for several tide cycles from
Wednesday night through at least Thursday night. See the
Tides/Coastal Flooding section below for details.

Thursday...

Thursday will be the most active weather day of the mid-late week
period as a strong storm system passes over New England,
strengthening as it does. At the synoptic scale we see a sprawling
upper level low and sfc reflection move into the Great Lakes region
early Thursday morning, spawning a secondary triple point low over
or near southern New England. This system bring plenty of moisture,
very good dynamics, and some elevated instability to boot. Ahead of
the low a very strong 45-55kt 850 mb LLJ moves overhead (2-3
standard deviations stronger than average) pulling in a plume of
moisture on southerly flow. PWATs approach 1" while dewpoints may
get into the low 50s. There remains some discrepancy on exact low
placement and extent of moisture advection among the guidance but
the potential is good for a very moist and dynamic system. A robust
vortmax, strong LLJ, and approaching cold front will lead to
widespread heavy rain; up to a half inch is likely, with locally
higher amounts before mid/upper level dry air surges in behind the
cold front. The front moves offshore sometime in the evening or
early overnight hours. I've added a chance of thunderstorms on
Thursday as well, with such a dynamic system, some instability, and
ample shear. It starts with several hundred J/kg CAPE in western
MA/CT late morning shifting east through the afternoon. Mid level
lapse rates are favorable, near 7C/kg while the strong LLJ
contributes to 0-6 km bulk shear values >70 kts.

Friday...

Guidance has begun to come into better agreement as to how quickly
the low then lifts out into ME overnight and into Canada Friday.
Meanwhile the upper trough remains overhead keeping cyclonic flow in
place as wraparound moisture and a strong westerly LLJ brings a
resurgence of lighter rain showers and even high elevation snow on
Friday. Best chance for showers and even a few rumbles of thunder
comes during the afternoon as diurnal heating and the cold pool
aloft contribute to some marginal instability, though the shear is
very much lacking by then. High temperatures reach into the upper
40s to low 50s.

Saturday through Monday...

The weekend looks drier as a ridge of high pressure makes its way
overhead. Going with a blend of guidance we can expect dry weather
through the weekend before our next storm potential comes early next
week. Temperatures top out near normal on Saturday, in the low 50s,
but another warm up is ahead. Southerly flow out ahead of the early
week trough will bring a few days of more mild temps beginning
Sunday approaching 60, and into the low 60s by Monday.

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
Forecaster Confidence Levels...

Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.

18z TAF Update:

Rest of Today: High confidence.

VFR with FEW-SCT fair weather Cu. West winds 8-12 kt, gusts to
20-25 kt. Toward late-day (into the 21z/evening push period),
winds near the coast should turn ESE around 5-8 kt.

Tonight: High confidence in trend, moderate on timing.

Increasing/lowering clouds associated with a warm front which
will eventually spread rains across the TAFs. Initial VFR with
deterioration to MVFR ceilings (possible IFR ceilings south of
BDL to PVD to the Cape airports) after 05-07z with VFR-MVFR
visby rains spreading ESE through 08-12z. Due to the dry air
around, timing is a bit uncertain but could be an hour or two
sooner than indicated in the TAFs.

Through midnight, mainly light/variable winds in the interior,
SE 5- 8 kt towards the Cape and at BOS. After midnight thru 12z,
winds to shift to NE around 5-10 kt as front slides S of the
coastal waters.

Wednesday: High confidence in trends, moderate on timing.

Initial MVFR, possible IFR with periods of rain to generally
taper off through the morning. Gradual improvement from
widespread MVFR to MVFR/VFR levels toward the afternoon. NE/ENE
winds 4-8 kt in the interior, around 7-10 kt with occasional
gusts to 20 kt coastal MA and the Cape.

Wednesday Night: Moderate to high confidence.

Increasing moisture levels on SE flow will result in VFR-MVFR
ceilings lowering to MVFR-IFR levels in the interior and across
the higher terrain. For the coastal plain into the Cape, initial
VFR to trend VFR/MVFR into the pre-dawn hrs. Rains should hold
off until the pre-dawn hrs in the CT Valley with dry conditions
elsewhere. SE winds 6-10 kt.

KBOS Terminal...High confidence in the TAF. West winds to shift
to SE late afternoon (~21-22z).

KBDL Terminal...High confidence in the TAF.

.FIRE WEATHER...
Min Relative humidities are expected to fall to 20 to 30 percent
this afternoon away from the coastline. This combined with WNW winds
10-15 mph with gusts up to 20 mph along with dry weather will yield
an elevated fire weather concern. Thus will continue the Special
Weather Statement that was issued last evening.

.TIDES/COASTAL FLOODING...
Astronomical tides are on the rise (across multiple tidal cycles)
this week with the upcoming Supermoon.  Stevens Institute indicates
both tide cycles on Wed (midday and midnight) across eastern MA may
