615 am est Wed dec 12 2018

Synopsis
High pressure builds across the area today through Friday. Low
pressure passes to our south Saturday, and could bring some
light rain to southern areas, with snow or rain showers in the
mountains.

Near term until 6 pm this evening
615 am... Weak interaction between 500 mb trough overhead and
coastal low passing well to our SE is setting up some clouds and
some snow showers flurries, mainly over the mtns and the ern
zones. These are generally very light and should not do much as
far as accums go. The trough axis swings E of the CWA shortly
after 12z, so these should winds down, and nnw flow should allow
downslope to mix out most of the clouds during this morning,
with mainly sunny skies by afternoon.

Previously... Light snow associated with inverted trough still
occuring, mostly in knox and waldo counties. Based on radar
trends and hrrr just assuming this is putting precip about 50
miles too far east this should slowly move offshore by 09-10z,
and the forecast reflects that. Could see an additional few
tents of an inch in some spots. Also, clear slot between
approaching 500 mb wave to the NW and the inverted trough, has
wreaked havoc with overnight temps as rad cooling has brought
some places like kizg down to near zero, although as the
clouds roll in from the west temps should move back up before
sunrise.

For the daylight hours of today, should see clearing this
morning, with sunny skies this afternoon, and a nnw wind, which
will likely do more for warming in downslope than for any caa
behind the system, so highs will range from the upper teens and
low 20s in the n, to around 30 in the south.

Short term 6 pm this evening through 6 pm Thursday
Tonight, should see clear skies and rapidly diminishing winds
after sunset. Should be a good long rad cooling night,
especially away from the coast, so lows will like range zero to
-10 in the mtns to around 10 on the coast and in SRN nh. Coastal
areas will likely see enough bl flow to prevent full on rad
cooling.

Thu, despite plenty of sun, will feature light winds, and with
temps starting cold, and the almost minimum Sun angle, highs
will be similar to wed, despite some warmer air aloft.

Long term Thursday night through Tuesday
Ensemble and deterministic model solutions are in good agreement
on the long wave pattern through the first half of the upcoming
weekend. Unfortunately... The progressive pattern adds considerable
uncertainty to timing and intensity of sensible weather details
as we head deeper into the extended period. We begin the forecast
period with rising heights and surface high pressure across the
region for Thursday night and Friday. A northern stream impulse
then drives a cold front across the area Friday night and
Saturday. That's a big change from earlier model solutions that
favored southern stream energy and a warm and wet coastal system
for the weekend. Instead... Ridging behind the departing northern
stream energy should provide a dry and seasonable second half to
the weekend as a southern stream disturbance is suppressed to our
south and east. Late Monday and Monday night the next northern
stream impulse will drive a moisture starved cold front across the
region followed by building high pressure into mid weekend.

Aviation 11z Wednesday through Sunday
Short term... Some periods of MVFR possible at rkd through about
10z, and khie through about 14z, otherwiseVFR through thu.

Long term...

fri night - sat... Areas of MVFR in -shra -shsn.

Marine
Short term... SCA winds should begin to develop early this
morning and continue into this evening, before diminishing
tonight into Thursday.
