Area Forecast Discussion
National Weather Service Burlington VT
406 AM EDT Thu May 4 2017

.SYNOPSIS...
High pressure currently over the region. Today will be dry with
increasing clouds, before widespread rain arrives on Friday.
Weather will remain unsettled over the next week with large
upper level low pressure system remains anchored over the
Northeast.

&&

.NEAR TERM /THROUGH FRIDAY/...
As of 404 AM EDT Thursday...Surface high pressure begins to slide
east away from the region this morning as warm front approaches
from our southwest. Most of the day will be dry with increasing
clouds before showers begin to move into the southwestern zones
late Thursday evening. Saint Lawrence valley will have the best
chance for precipitation, before rain spreads further east 
overnight. By Friday morning low pressure approaches from the 
southwest and stratiform rain is expected across our area and 
becomes widespread by early afternoon. Some of the models hint a
bit of a break in the precipitation Friday evening in the 
Champlain Valley, which could lead to a couple hours of gusty 
downslope winds before precipitation picks back up again. 


Maximum temperatures Thursday will be in the upper 50s to lower
60s while Thursday night lows will be in the upper 30's to low
40's. Temperates will be cooler Friday with highs in the upper
40's and low 50's. 

A frost advisory is in effect for the Champlain valley, which 
is the only area which has begun it's growing season as of May 
1. The Advisory runs from 05-11z. Temperatures will warm 
following sunrise at 539 am.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SATURDAY/...
As of 349 AM EDT Thursday...A highly amplified mid-upr
tropospheric flow pattern will bring continued unsettled weather
to the North Country during Friday Night/Saturday. Main trough
axis expected to extend from the nrn Great Lakes swd across the
central/srn Appalachians  will be associated with deepening sfc
low across nwrn PA/wrn NY during Friday night. Should see North
Country emerging into cyclone warm sector during this time frame
with potential mid-level dry slot developing nwd across the
region. Thus, the steadier precipitation should be translating
north of the area with lighter/intermittent shower activity for
the majority of the overnight hrs. Will also need to monitor
downslope winds on the wrn slopes of the Greens. May see a brief
window of 30-40 mph sely gusts as rain ends and p-gradient
remains strong during the first half of Friday night. Should see
overnight lows mainly in the mid 40s. 

On Saturday, should see deepening sfc low (~990mb) passing to
our west with mid-level low cutting off across the srn Great
Lakes and Ohio Valley areas. Still looking at mid-level dry slot
in deep-layer sly flow regime. Carried 40-60 PoPs for scattered
rain showers, with a slight chance of a thunderstorm based on
SPC SREF calibrated tstm probabilities of 20-30% during the aftn
hours. High temps currently forecast 65-70F, but could be
slightly higher depending on overall breaks/sunshine.

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
As of 349 AM EDT Thursday...The 00Z NWP guidance suite remains
consistent with the idea of a deep layer closed low and mid- 
level thermal low stagnating across the nern CONUS for an 
extended period of time beginning Saturday night. This will 
bring a persistent forecast of unsettled conditions. While it 
won't be raining constantly, looking for generally mostly cloudy
and cool conditions, with periods of rain showers, as thermal 
trough aloft generates shallow instability with any breaks in 
the overcast during daytime periods. Below normal high 
temperatures (generally in the 50s, but upr 40s possible on 
Monday) are expected starting on Sunday and continuing right 
into the middle part of next week. The coldest area of 850mb air
(-5C to -6C) may even bring a few snow showers to the highest 
summits Sunday night, and again on Monday night.

&&

.AVIATION /08Z THURSDAY THROUGH MONDAY/...
Through 06Z Friday...VFR conditions will persist outside of a 
few areas of patchy fog overnight as clearing skies and 
subsiding winds lead to good radiational cooling night. KMPV and
KSLK air temperatures will fall below their cross over 
temperature mainly around 08Z-11Z, have included tempo for this 
time period of MVFR/IFR cigs. This low level moisture and cross 
over temperature will be in contrast to overall drier air 
filtering in on NW flow, which is evident in dewpoints in the 
mid 20s entering into the St Lawrence Valley. Dry weather 
continues into Thursday before more showers and increasing 
clouds move in late Thursday night. 

Winds will be light overnight as surface high pressure crests 
over the region. Winds will pick up generally out of the south 
at less than 10 kts. 

Outlook...

Thursday Night: VFR/MVFR. Likely RA.
Friday: VFR/MVFR. Breezy. Definite RA.
Friday Night: MVFR. Breezy. Likely SHRA.
Saturday: VFR. Chance SHRA...TSRA.
Saturday Night: MVFR. Likely SHRA...TSRA.
Sunday: VFR/MVFR. Likely SHRA.
Sunday Night: VFR/MVFR. Chance SHRA.
Monday: VFR/MVFR. Chance SHRA.

&&

.BTV WATCHES/WARNINGS/ADVISORIES...
VT...Frost Advisory until 7 AM EDT this morning for VTZ001-002-005-
     009.
NY...Frost Advisory until 7 AM EDT this morning for NYZ028-035.
