Area Forecast Discussion
National Weather Service Boston/Norton MA
1006 AM EST Thu Jan 31 2019

.SYNOPSIS...
Dry, but bitterly cold temperatures continue today into Friday
morning. Temperatures will slowly moderate this weekend with
mainly dry weather persisting. Much milder weather is on tap for
Monday and especially by Tuesday with well above normal
temperatures expected. Unsettled weather may arrive sometime
Wednesday or Thursday, but there is significant uncertainty in
temperatures and precipitation chances.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...

10 am update...

Clear skies and bitterly cold temperatures continued during this
morning. A Wind Chill Warning continued thru 11 am for the east
slopes of the Berkshires, and a Wind Chill Advisory continued
for northern Worcester County until 11 am.

Elsewhere, while we are moving out of the deeper wind chills,
it will still be bitterly cold today. The brisk west wind will
prompt wind chills to range from 5 above to 10 below zero during
late this morning into this afternoon.

Large high pressure will pass across the mid Atlantic states
today, keeping a gusty west wind in place. High temperatures
range from the single digits to teens across most of the
region, except upper teens to around 20 closer to the shoreline
and over the Cape/Islands.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/...
Tonight and Friday...

Large high pressure will slowly shift east across the mid Atlc
states tonight into Friday. Will still see westerly winds to
around 20-25 kt, highest along the immediate E coast, this
evening but should diminish around or after midnight. With the
diminishing wind, temps will nosedive once again with the very
dry airmass in place. Overnight lows will range from 5 to 10
below zero across N central and W Mass to the lower-mid teens
across the outer Cape and islands.

The high will remain across the mid Atlc coast on Friday. Temps
will moderate, with highs in the teens to mid 20s.

&&

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
Highlights...

* Mainly dry this weekend with highs generally in the 30s to near 40

* Low risk for a brief light wintry mix Sun night with best chance
  near the NH border

* Unseasonably mild Mon and particularly Tue when highs around
  60 are possible

* Low confidence forecast Wed/Thu especially with temperatures and
  precipitation chances

Details...

Friday night...

High pressure in control will result in dry weather with light
winds.  It still will be quite cold with a good night of radiational
cooling expected, particularly in the snow covered/out-lying
locations.  Low temperatures should bottom out in the single digits
to lower teens in most locations.

Saturday and Sunday...

We will see some moderation in temperatures as deep upper trough
lifts northeast of our region.  However, another surface high
pressure builds across Quebec late Sat into Sun.  This will limit
the moderation in temperatures to some degree...keeping highs mainly
in the 30s Sat/Sun but its not out of the question that a few
locations reach 40 on Sun.  Dry weather should prevail, but can not
rule out a brief flurry/snow shower late Sat/Sat night with a cold
front. However, moisture is extremely limited so overall expect dry
weather.

Sunday night...

A warm front will attempt to lift across our region Sunday night.
Deeper moisture/forcing associated with the warm front are limited.
We can not rule the low risk for a brief light wintry mix sometime
Sun night with the best chance near the NH border.  If we do see any
precipitation it appears it will be rather light.

Monday and Tuesday...

GEFS/EPS Ensemble guidance in very good agreement in a trough across
the western U.S., resulting in southwest flow aloft and anomalous
high height fields into New England.  The result will be well above
normal temperatures. Highs Mon will likely be 50+ in some
locales and may reach the upper 50s to the lower 60s on Tue.
Dry weather probably dominates over this time too given lack of
strong forcing/moisture. However, can not rule out a shower or
two from time to time. Main story though will be the
unseasonable mild temperatures.

Wednesday and Thursday...

Low confidence forecast Wed into Thu especially in regards to
temperatures.  Abnormally high height fields continue, but there are
signs that we may be dealing with a backdoor cold front.  Therefore,
a large range in possible temperatures.  It also may become
unsettled at times with perhaps a wave or two of low pressure, but
timing is uncertain.
