Area Forecast Discussion
National Weather Service Boston/Norton MA
204 AM EDT Fri May 8 2020
.SYNOPSIS...
Cold front slides through tonight bringing light scattered rain
showers. Dry weather to start Friday, but an arctic wave of low
pressure brings more rain Friday night which will likely change
to a period of accumulating snow inland and especially in the
higher elevations. Blustery and near record cold follow Saturday
with scattered rain and higher elevation snow showers. Then dry
weather with moderating temperatures follow Sunday. Low
pressure may bring a period of rain around Monday followed by
drier but cool weather Tuesday into Wednesday. A pattern change
to warmer weather is possible late next week and beyond.
&&
.NEAR TERM /UNTIL 6 AM THIS MORNING/...
1045 pm Update:
Cold front making its way through eastern NY at this hour, with
radar indicating scattered light rain showers along it. 00z
RAOBs from ALB and OKX indicate very dry low-levels so wouldn't
expect much QPF in these showers. However may be some briefly
gusty winds in the showers, particularly in western/central MA
and into the CT valley - thinking potential for 25 to 35 mph
gusts in the showers should be common. Recent base velocity
scans from ENX radar reflects this potential, particularly in
some of the stronger returns. Showers should weaken in areal
coverage and strength as it moves east into the coastal plain.
Will see west winds pick up post- frontal as skies start to
clear with lows mid 30s to mid 40s.
====================================================================
Highlights...
* Cold front slides through bringing light scattered rain showers.
A ridge axis will slide offshore while a cutoff low rotates
southeastward from northern Ontario into the Quebec/Ontario border.
A shortwave will rotate around the cutoff from southeast Ontario
into northern New England. Low pressure will deepen across southern
Quebec and the cold front associated with the low will slide from
the eastern Great Lakes through southern New England.
Good agreement amongst deterministic and ensemble guidance at this
point in time. Nudged the QPF values toward the 50th percentile of
guidance based on the clustering of values. This results in rain
totals of a few hundredths of an inch. Expect this activity before
midnight.
A mid level ridge axis builds in late, which will decrease cloud
cover. West winds picking up in wake of the cold front. This is
evident by the adiabatic lapse rates within the boundary layer per
deterministic guidance. This will bring gusts of 15 to 25 mph toward
daybreak.
&&
.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM SATURDAY/...
Highlights...
* Precipitation spreads in from southwest to northeast during the
afternoon and into Friday evening.
* Rain changes over to snow Friday night into early Saturday.
Expect anywhere from a coating to 2 inches of snow
accumulation across the higher elevations of the interior.
Friday...
The cutoff previously mentioned will continue rotate southeastward
on Friday into early Saturday. This phases with energy from a
shortwave ejecting from the Central/Southern Plains. This phasing
will occur later on Friday and will deepen a low over the Mid
Atlantic and lift it into and through Southern New England. The warm
front associated with this deepening system will lift into the
region during the afternoon and into the evening.
Expect a dry start to the day with some weak mid level ridging in
place ahead of the incoming system. As the warm front lifts into the
region will see precipitation gradually spread in from southwest to
northeast during the afternoon and heading into the evening. Pretty
good consensus amongst guidance at this point in time. Expecting all
rain initially. Will be cooler than normal with highs ranging from
the upper 40s to the low 60s.
Friday Night...
Model and ensemble solutions diverge with the track and intensity of
the system sliding through the region. At this point in time there
are three solutions. An intense low slowly sliding into Cape Cod and
the Islands overnight as advertised by the GEFS and GFS models. The
much weaker and more progressive NAM/UKMET guidance which slides the
system into the Gulf of Maine by Saturday morning. Finally the
compromise between the two of the ECMWF/GEM and HREF guidance. The
EPS for only being 30-48 hours out shows a significant amount of
spread. This is also something that is seen at 850 hPa.
Have leaned toward the compromise between the solutions ie the
ECMWF/GEM and HREF guidance. The bullish GFS is hard to believe
given that the GEFS QPF values greater than 1 inch is around 10 to
30 percent across portions of southern New England while the EPS
continues to show 0 percent chance of QPF greater than 1 inch. This
is important with regards to accumulating snowfall for this time of
year because some of the QPF is wasted in the transition to snow and
in cooling down the surfaces to accumulate.
Models have all trended the heaviest QPF axis further to the
southeast, so have reflected this change in the latest forecast and
snowfall amounts anticipated. Will need to keep a close eye on where
the frontogenetical band sets up. As of right now looks mostly like
northern CT/RI into central MA. As of right now expect totals
between a dusting to 2 inches across the higher elevations. Not out
of the question if a strong band sets up that a few spots see 3 to 4
inches of snowfall accumulation. Not anticipating much if any
accumulation on the roadways, so most of this will fall on the
cooler elevated surfaces. Expect this snow to be quite heavy with
snow ratios of 5:1 to 8:1. Think if we can get a heavier band and
spots where there are 3 to 4 inches of accumulation that power
outages will be possible.
Brought down low temperatures toward the 25th percentile of guidance
given the strong northwesterly cold air advection. Will see 850 hPa
temperatures of -5 to -10 degrees Celsius moving in. Low
temperatures will generally be in the 30s across southern New
England.
&&
.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
Highlights...
* Arctic blast Sat with near record cold bringing March-like temps
* Dry with moderating temperatures Sunday
* Monday, chance of rain then dry with temperatures slightly cooler
than normal Tue/Wed
* Pattern change possible to warmer weather late next week & beyond
Saturday ...
12z Sat arctic frontal wave off the coast of ME and rapidly
intensifying into a gale center with a sub 980 low over the
Maritimes by 00z Sun. Any lingering comma-head rain/snow will taper
off around or shortly after daybreak. However additional scattered
rain/snow showers possible during the day as very anomalous cold
pool of -35C to -40C (all time record for May!) combines with
cyclonic flow aloft as polar mid/upper low traverses the region.
Given magnitude of cold air aloft could have shallow but robust
updrafts supporting some graupel mixing in with the rain/snow
showers.
Regarding winds...strong pressure gradient and steep low level lapse
rates in response to anomalous cold air aloft and strong May
insolation will support blustery WNW winds of 20-30 mph with gusts
up to 50 mph possible. Thus will likely need a wind advisory as the
event nears. Could be some minor tree damage (small limbs down)
given trees becoming fully leaved but given gusts expected to remain
less than 60 mph, any tree damage should be isolated and not
widespread.
As for temperatures...anomalous 850 mb temps of -6C to -7C along with
mostly cloudy conditions will only support highs in the mid to upper
40s, with upper 30s to lower 40s high terrain! These values will be
near record cold highs for the day. Blustery WNW winds will yield
wind chills in the 30s! More typical of March not May. See climate
section below. Normal high this time of year is 65-70.
Sat night ...
CAA peaks with 850 mb temps falling to about -8C to -9C! This will
yield near record low temps in the upper 20s to lower 30s, mid 30s
along the coast including Boston. Gusty WNW winds will continue and
result in wind chills in the teens and 20s!
Sunday ...
After a very cold start to the day height rises and temps warming
aloft will support highs well into the 50s, tho still 10-15 degs
cooler than normal. More sunshine and less wind than Sat (albeit
still breezy) will be a big improvement.
Next Week ...
Ensembles suggest one more piece of modified arctic air takes aim at
southern New England early next week. Frontal wave along this
boundary may bring a risk for showers Monday. Ensembles suggest post
frontal airmass over the area Tue, thus dry but cool reinforcing
surge of CAA, although not nearly as chilly as Sat/Sat night. Dry
and cool into mid week with possible pattern change toward warmer
weather beginning late next week.

.TIDES/COASTAL FLOODING...
Very high astronomical tides tonight around midnight will push water
levels near flood stage. Not much of a surge except south coast with
WSW winds ahead of cold front may yield up to 1 ft storm surge.
Although pres falls from approaching front will contribute to minor
surge for the entire coastline of MA/RI. Thus continue to expect
minor coastal flooding and will stay the course with current
headlines. May have a second round of minor coastal flooding
tomorrow night as well.
