Area Forecast Discussion
National Weather Service Burlington VT
425 AM EDT Fri May 5 2017

.SYNOPSIS...
A large upper level trough of low pressure begins to settle over the 
eastern third of the US. Deep moisture will move northward into the 
region and with it increasing clouds and precipitation growing more 
widespread by Friday afternoon. This large low pressure system will 
settle in over the region this weekend for the better part of the 
next week. With this, cloudy conditions and periods of showers for 
the weekend and most of next week are expected along with 
slightly below normal temperatures.

&&

.NEAR TERM /THROUGH SATURDAY/...
As of 406 AM EDT Friday...Large upper trough settles in across the
Eastern third of the US this morning and will dominate the near
term . Plenty of clouds along with widespread rain is expected 
as the day progresses. Steadiest and heaviest rain looks to be 
Friday afternoon into the late evening before a dry slot moves 
into the region Friday night, decreasing but not ending the rain
in all areas. 

Moving to Saturday, things still looked unsettled but conditions 
should be better overall as the deepening surface low passes to our 
west with a mid-upper level circulation cutting off over the eastern 
Great Lakes. Positioning of the upper level low and associated 
southerly flow ahead will advect a mid-level dry slot into the North 
Country, most prevalent across Vermont. The result will be mainly 
dry conditions from the Champlain Valley eastward, while for points 
westward begin dry in the morning before showers redevelop in 
the late afternoon through the overnight hours as the upper low 
builds overhead. Later in the afternoon some gusty downsloping 
winds are possible in the Champlain Valley with some gusts as 
high as 30mph.


Friday will see highs in the upper 40s to lower 50s, with lows not 
much cooler with the southerly flow, 40s across the CWA. Highs for 
Saturday look to be in the mid to upper 60s, with low 70's a 
possibility in the Champlain Valley if we see enough midday clearing 
and sunshine.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY NIGHT/...
As of 423 AM EDT Friday...A generally unsettled pattern throughout 
the short-term forecast period as slow-moving/closed 500mb low 
across the ern Great Lakes region remains our dominant weather 
feature throughout the weekend. It appears ~990mb sfc low will 
slowly fill as it lifts nwd into the Ottawa Valley and swrn 
Quebec during Saturday night. May see a few showers during the 
period, but weak low-level convergence/wind fields suggest 
overall coverage of precipitation will be limited. A trailing 
sfc trough/weak frontal zone will push ewd across nrn NY and VT 
during the day Sunday, and may serve to organize shower 
activity, especially by Sunday afternoon. Have shown highest 
PoPs during Sunday aftn/eve, reaching 60-70%, with rainfall amts
ranging from 0.05-0.15", highest across ern VT. Should see a 
bit more of an orographic/NW low-level flow pattern by Sunday 
night as sfc low consolidates across srn Quebec/nwrn Maine. With
cooling thermal profiles (850mb temps progged -4C to -5C across
nrn NY), may see some snow shower activity during Sunday night 
across the nrn Adirondacks, and perhaps across the higher 
summits of the Greens toward daybreak Monday. Just periodic 
light -RW anticipated elsewhere. Low temps in the mid-upr 40s 
Saturday night. Highs in the lower 60s on Sunday (except low-mid
50s across nrn NY following trough passage), and then lows in 
the upr 30s to lower 40s on Sunday night, except near 32F across
the nrn Adirondacks.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
As of 423 AM EDT Friday...Blocking pattern over the CONUS will 
prevail. Large, closed mid-upr tropospheric low over the nern 
CONUS will bring continued mostly cloudy, cool, and showery 
conditions to the North Country through the period. Don't 
anticipate any "washout" type days, but can't rule out scattered
showers each period, which is reflected by extended periods of 
30-40 PoPs. In fact, total rainfall should generally be less 
than 0.5" in most valley locations through the period, so not 
looking at anything particularly heavy. Thermal profiles also 
continue to support a few snow showers across the Adirondack 
high peaks region Monday night, which may result in coating to 
2" snowfall at summit level. The 00Z ECMWF offers some signs 
that the closed low will push far enough east of New England 
that Thursday may finally trend drier with potential clearing. 
This trend is slower in the 00Z GFS, which reflects the official
forecast at the moment. Pattern supports temperatures several 
degrees below normal overall. It appears high temperatures 
through the period will generally be in the low-mid 50s Monday 
and Tuesday, before trending into the upr 50s on Wednesday and 
lower 60s generally for Thursday. Lows will mainly be in the 
low-mid 40s in valley locations. 

&&

.AVIATION /09Z FRIDAY THROUGH TUESDAY/...
Through 12Z Saturday...Strengthening low pressure across the
central Appalachians will track newd into n-central 
PA/s-central NY by 12z Saturday. This system will bring OVC 
conditions and periods of rainfall, which will be steadiest 
during the afternoon hours, and possibly briefly moderate in 
intensity between 18-21Z. Will see a mix of VFR/MVFR conditions,
generally becoming MVFR areawide tonight as ceiling heights 
lower to 1.5-3kft. S-SE winds initially 5-10kts will increase to
12-18kts by this afternoon, with gusts 20-25kts possible. Local
downslope conditions likely at KRUT, with gusts 25-30kts 
between 17-00Z. Will see winds diminish tonight, becoming light 
south 5-10kts. 

Outlook...

Saturday: VFR. Breezy. Chance SHRA.
Saturday Night: VFR/MVFR. Breezy. Chance SHRA.
Sunday: VFR/MVFR. Likely SHRA.
Sunday Night: VFR/MVFR. Chance SHRA.
Monday: VFR/MVFR. Chance SHRA.
Monday Night: VFR/MVFR. Chance SHRA.
Tuesday: VFR/MVFR. Chance SHRA.
