309 AM EDT Sun Jun 16 2019

A cold front will become quasi-stationary across east-central
New York into Massachusetts, with a continued potential of rain
showers across southern Vermont today. Further north, skies
will trend partly sunny with light north to northwesterly winds.
Temperatures will be a bit lower than yesterday, with valley
highs mainly in the low to mid 70s. Dry and seasonable
conditions are expected tonight through Tuesday, though there
will be some potential fog in favored valley locations during
the overnight hours. The next widespread rainfall is not
expected until Thursday or Friday as low pressure approaches
from the Ohio Valley.


As of 130 AM EDT Sunday...Surface cold front will settle just
south of our forecast area this morning with lingering showers
across central/s-central VT generally ending by 09-10Z. Winds
will shift light nwly later this morning across the northern
half of the forecast area along with partial clearing.
Meanwhile, it continues to appear that shortwave trough across
central Ohio will track enewd along the quasi-stationary frontal
zone later today, bringing a renewed threat of rain showers
across mainly Rutland and Windsor counties between 15-21Z.
Indicated PoPs increasing back to 50-70% there, with potential
for 0.15 to 0.30" rainfall across s-central VT. Temperatures
will be somewhat cooler than yesterday, with highs 72-74F across
the northern valleys with some sunshine, but closer to 68-72F
across s-central VT with mainly cloudy skies and periods of rain
showers during the mid-day/afternoon hours.

All areas become mostly clear this evening from NW-SE. Looking
at tranquil conditions for tonight and Monday with weak high
pressure building in from Ontario. Appears we`ll reach crossover
temperatures overnight and with wet soil conditions and light
winds, have included fog in favored valley locations for
tonight. Overnight lows mainly in the upper 40s to lower 50s.
Temperatures climb into the 74-78F range for highs on Monday
with winds remaining light NW at 5-10 mph with mostly sunny


As of 308 AM EDT Sunday...We continue to highlight a generally dry
period for the early part of next week as weak surface high pressure
persists over the region and a frontal zone situated south of the
area. Can`t rule out a few isolated afternoon showers with some weak
impulses of shortwave energy passing through a fast westerly flow
aloft, especially across southern Vermont closer to the frontal
zone. Won`t see much in regard to wind and skies should be partly
cloudy in general with a potential for isolated river valley fog
Monday night. Temps Tuesday/Wednesday should warm above normal with
925mb temps of +16- 20C supporting highs well into the 70s with
locally lower 80s possible in the St. Lawrence and Champlain
Valleys. Lows will be seasonal ranging from the upper 40s to upper


As of 308 AM EDT Sunday...Good model consistency persists for the end
of the work week showing a potent shortwave trough and vertically
stacked low pressure system lifting out of the Ohio Valley Thursday
afternoon/night moving east of the benchmark either by Friday
evening or Saturday morning. Some discrepancy cropped up with timing
on this mornings 00z runs as compared to yesterday with the GFS now
slower and the ECMWF/CMC more progressive. Kept with consistency and
leaned towards the faster solutions which bring moderate to isolated
heavy rain into the region Thursday afternoon through Friday
morning. Good surge of PWATs of 1.5 to 1.75" and generally weak flow
below 500mb should support a decent soaking with the potential for a
couple inches of rain. Given the dry antecedent conditions not
expecting any hydro issues, but the progress of this system
certainly bear monitoring through the week.

Behind this system high pressure looks to return for Saturday with
drier conditions and temps near normal.


Through 12Z Monday...A few lingering rain showers are expected
at MPV/RUT through 09Z as a cold front settles south of VT and
stalls across central New England. Within the frontal zone, will
see continued IFR ceilings at SLK thru 11-12Z, and periods of
MVFR ceilings at MPV/RUT with HIR TRRN OBSCD. Mainly VFR
elsewhere. As we reach the daylight hours, conditions will
generally be improving to VFR across all of nrn NY and most of
central/nrn VT. It appears that additional showers will develop
and affect RUT during the late morning through the afternoon
hrs, and periods of -SHRA with accompanying 3-5SM vsby can be
expected locally at RUT. All sites clear out for tonight, but
anticipate some fog development at MPV/RUT/SLK during the pre-
dawn hours Monday. Winds generally light north to northwest
today at 3-8kt, then light and variable for the overnight


Sunday Night: VFR. NO SIG WX.
Monday: VFR. NO SIG WX.
Monday Night: VFR. NO SIG WX.
Tuesday: VFR. Slight chance SHRA.
Tuesday Night: VFR. Slight chance SHRA.
Wednesday: VFR. Chance SHRA.
Wednesday Night: VFR. Chance SHRA.
Thursday: Mainly VFR, with local MVFR possible. Likely SHRA.
