Area forecast discussion, Apr 7, 2:59 PM EDT, 29 minutes before
Area Forecast Discussion
National Weather Service Boston/Norton MA
259 PM EDT Sat Apr 7 2018
.SYNOPSIS...
A coastal storm tracking well offshore may bring a brief period
of light snow late tonight and early Sunday for Nantucket.
Otherwise, dry and cool weather persists into Monday. Low
pressure looks to develop too far east of the region to bring
significant precipitation to the region Tuesday and Tuesday
night...but still bears watching. Milder weather arrives by
Wednesday and Thursday, but nothing too springlike expected.
&&
.NEAR TERM /THROUGH TONIGHT/...
Consensus of global and hi-res guidance keeps frontal wave well
offshore with only impact to Nantucket and possibly the outer
Cape with a period of light snow late tonight and early Sunday.
Guidance supports up to an inch accum for Nantucket, mainly on
non paved surfaces as temps expected to remain just above
freezing. Otherwise, dry and cold conditions with mid/high
clouds moving back across the region this evening before
clearing from the north late tonight.
&&
.SHORT TERM /SUNDAY THROUGH SUNDAY NIGHT/...
Sunday...
Light snow over Nantucket and possibly the outer Cape will end
by mid morning, then clearing in the afternoon. Elsewhere,
sunshine will give way to broken cloud cover in the afternoon as
low and mid level moisture increases ahead of approaching mid
level trough. Steep 925-700 mb lapse rates develop in the
afternoon, but moisture is limited. Still, can't rule out a few
late day snow showers in the interior. Another day with well
below normal temps in the mid 40s, colder higher terrain. Gusty
north winds 20-30 mph will develop over Cape/Islands.
Sunday night...
Clouds and a few snow showers possible in the evening with mid
trough passage, then clearing skies expected. Another surge of
gusty winds will likely develop over Cape/Islands with the
trough passage. Unseasonably cold temps for the 2nd week of
April with lows upper teens to mid 20s.
&&
.LONG TERM /MONDAY THROUGH SATURDAY/...
Highlights...
* Mainly dry but unseasonably chilly Sunday night into Mon
* Low risk for a bit of rain or even wet snow Tue/Tue night
* Milder Wed/Thu but nothing too springlike
* Low confidence by next Saturday but odds against very mild temps
Details...
Monday...
A ridge of high pressure builds in from the west which should result
in a fair amount of sunshine. Below normal temperatures will
continue though with highs in the 40s.
Tuesday and Tuesday night...
We still need to watch low pressure that will be emerging off the
mid Atlantic coast. However...the trend of the guidance over the
past day or two has been not to phase northern and southern stream
energy. The result is a weaker system that also tracks further
southeast. Current data would suggest a few rain/snow showers as
the most likely scenario Tue and/or Tue night with minimal impact.
Given the time range...there still is a low risk for a
stronger storm that tracks closer to the coast or even an inverted
trough type of setup. While this is a lower probability at this
point...a more significant period of rain or perhaps wet snow still
can not be ruled out.
Wednesday and Thursday...
Upper trough lifts out of the northeast allowing more of a zonal
flow/milder temperatures. This should result in many locations
seeing highs in the 50s both days. Nothing too springlike...but an
improvement over what we have been dealing with of late. Dry
weather dominates over this time...but a few showers are possible
especially on Thursday with an approaching shortwave/cold front.
Friday and Saturday...
Very large spread in the model guidance from a springlike GFS,
to the ECMWF/GGEM that have a Canadian high pressure nosing
down resulting in cooler temperatures by Friday or Saturday.
Given the time of year and pattern recognition would favor the
cooler scenario by the start of next weekend. Nonetheless...this
is 6 to 7 days in the future so can not rule out the more
springlike GFS solution.
