Area Forecast Discussion
National Weather Service Burlington VT
214 PM EDT Mon Jul 17 2017

.SYNOPSIS...
A slow moving upper level disturbance approaching from southern
Ontario will bring numerous showers and thunderstorms to the
area this afternoon and evening. The upper level disturbance
will move east on Tuesday but still a few additional showers or
thunderstorms are possible again especially over eastern
Vermont. A ridge of high pressure will bring warmer and drier
conditions to the area on Wednesday before another frontal
system moves in on Thursday and Friday with a chance of showers
and thunderstorms. Cooler and drier weather are likely by
Saturday under high pressure.

&&

.NEAR TERM /THROUGH TUESDAY NIGHT/...
As of 146 PM EDT Monday...Showers and thunderstorms ongoing
across the North Country as of 2pm. Severe thunderstorm watch is
in effect. There will be a threat for heavy rain as well as
damaging winds and hail in any thunderstorm. Previous discussion
follows.

Today continues to look active as the upper level trof moves
slowly into the St. Lawrence Valley. East of this feature,
ingredients are coming to together for scattered to numerous
showers and thunderstorms to develop as the atmosphere becomes
sufficiently destabilized by afternoon. CAPE of 1500-2000 J/kg
are expected. 0-6km shear is marginal at 20-30 kts with PW's
rising to 1.25" in the mountains to as high as 1.60" in the
valleys this afternoon. We should see showers and thunderstorms
become fairly numerous/widespread during peak daytime heating
hours. A few stronger storm cores are possible with potential
for pulse storms with gusty downdraft winds, small hail, and
heavy rainfall. Right now it looks like storms should propagate
slowly but steadily eastward to preclude widespread flash
flooding, but wouldn't be surprised to have one or two storms
produce rainfall of 2 inches or so which is right at flash flood
guidance thresholds for 1-3 hr duration. 850 temps should
provide high temps in the 80s especially from the Champlain
eastward where readings in the valleys should reach the mid 80s.

Tonight convective activity will slowly wind down with the loss
of insolational heating and should be most active as storms and
upper level trof propagate eastward through Vermont. Thus,
after midnight expect mainly dry conditions with mild temps in
the 60s under partly cloudy skies. Also expecting areas of dense
fog after 06z especially in the river valleys after all the
expected rain.

The upper level trough will continue to move east with rising
heights and warm advection Tuesday. It will move out of the the
North Country limiting sct showers and thunderstorms to south
and east VT through early afternoon. Again high temps in the
upper 70s to lower 80s with 850 temps around 13C.

&&

.SHORT TERM /WEDNESDAY/...
As of 310 AM EDT Monday...Relatively quiet period is expected
Tuesday night into most of Wednesday as weak high pressure
builds in behind departing upper trough. Dry weather is expected
Tuesday night through at least midday Wednesday. During the
afternoon hours we will see a front start to move down from
Canada and there may be some showers or thunderstorms near the
Canadian Border late in the day. Above normal temperatures are
expected with lows generally in the upper 50s to mid 60s and
highs on Wednesday in the 80s.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
As of 310 AM EDT Monday...Pattern becomes a bit more active
Wednesday night through Friday as west to northwest flow aloft
develops over the area and eventually more well defined front
moves down from Canada to further enhance the potential for
convection. Best potential for showers and storms will be
Thursday into Friday. Deep layer shear increases over the area
and instability develops ahead of the well defined cold front
moving south out of Canada. Time of day is not conducive as the
front does not look like it will move through until the
overnight hours Thursday night. Something to definitely keep an
eye on. Trend going into the weekend will be for a return to
more seasonal temperatures with northwest flow aloft over the
area. This pattern will help to keep the weather generally dry
over the weekend as well.

&&

.AVIATION /18Z MONDAY THROUGH SATURDAY/...
Through 18Z Tuesday...Locally MVFR/IFR visibilities in heavier
SHRA/TSRA+ this afternoon, as upper level trof moves eastward.
Could be some hail, gusty winds, and heavy rain with any TSRA.
Storms are pretty much past MSS and SLK but have TS mentioned at
all other TAF sites over the next couple hours. Winds light
and variable trending southerly 10 kts or less except higher
near TSRA. Some areas of IFR Fog developing toward 04-07Z
after all the rain with partial clearing and light winds.

Outlook...

Tuesday Night: VFR. NO SIG WX.
Wednesday: VFR. Slight Chance SHRA...Slight Chance TSRA.
Wednesday Night: VFR. Chance SHRA...Slight Chance TSRA.
Thursday: VFR. Chance SHRA...Slight Chance TSRA.
Thursday Night: VFR. Chance SHRA...Slight Chance TSRA.
Friday: VFR. Chance SHRA...Slight Chance TSRA.
Friday Night: VFR. Slight Chance SHRA...Slight Chance TSRA.
Saturday: VFR. Slight Chance SHRA.

&&

.MARINE...
A Lake Thunderstorm Advisory is in effect. A few showers and rumbles
of thunder are possible early this morning but stronger
thunderstorms will develop by this afternoon. Winds on the lake
will generally be light with nearly calm waves but a few of the
thunderstorms will be capable of variable and shifting wind
directions along with isolated higher gusts and chaotic waves.
There is also some chance that a few storms may contain hail,
frequent lightning, and torrential rainfall lowering
visibilities briefly to under a mile. Thunderstorms should wind
down early tonight.
