Area Forecast Discussion
National Weather Service Burlington VT
159 PM EDT Mon Jul 18 2016

.SYNOPSIS...
Scattered showers and thunderstorms, some strong to severe will
continue into this evening before a cold front brings cooler and
drier weather to the region for Tuesday into Wednesday. A return
to warmer more humid weather is expected from Thursday onward into
next weekend with a renewed threat for scattered showers and
thunderstorms.

&&

.NEAR TERM /UNTIL 11 PM THIS EVENING/...
As of 136 PM EDT Monday...Severe thunderstorm watch continues for
the entire North Country through 8PM EDT.

Scattered convection continues to produce strong to severe
thunderstorms across the North Country today in deep layer
moisture as dewpoints continue to be in the upper 60s. Main
threat today has been and will continue to be damaging winds, hail
up to an inch, heavy rainfall and dangerous cloud to ground
lightning.

Showers and thunderstorms will move into untapped instability
across central and eastern VT this afternoon, while cold front
draped across the eastern Great Lakes will progress eastward this
evening. With loss of heating the larger severe threat should
wane after 9 to 10 pm or so, but some lingering instability across
eastern VT will exit around midnight keeping chance for convection
through then. As frontal boundary swings through the area later
in the evening winds will shift to west/northwesterly and begin a
large- scale drying trend. Low temperatures generally in the 50s
to around 60 by daybreak Tuesday.

&&

.SHORT TERM /11 PM THIS EVENING THROUGH WEDNESDAY/...
As of 345 AM EDT Monday...Cold front and upper trough depart
region with surface high building into area with a comfortably
cooler/drier airmass for tue and wed. Highs will be only in lower
70s tues with just a few degs below seasonable normals for
wednesday. Dewpoints will be in the 40s with tue ngt lows in the
40s/50s across the region.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
As of 345 AM EDT Monday...The lifting of the trough that passes
across the region mon night allows rising heights for the
remainder of the week as the central CONUS heat ridge dominates
through the period.

Our forecast area never gets into the heart of the heat ridge yet
rising heights and southwest return flow will allow temperatures to
rise 5 to 10 degrees above normal through the period with increasing
humidity late week into the weekend.

There will likely be several disturbances along the northern
periphery of the heat ridge that will bring us multiple chances
of showers and thunderstorms...the question is just timing in a
fast zonal flow.

The first chance is looking like thu ngt/fri as a shortwave in the
WNW flow around the heat ridge moves across the area. timing appears
to be more thu ngt-fri thus missing peak heating on thu yet some
steep mid-level lapse rates with an elevated mixed layer advecting
into the region thus a chance of thunder late thu in the north with
continued threat thu ngt-fri and possibly linger into fri ngt.

I've left a chance of showers/thunderstorms for sat but pops have
lowered and think this may be the dry day of the weekend with some
shortwave ridging on the heels of the departing shortwave.

However...a surface warm front with a return of humidity may bring
us another chance of showers/storms sat ngt with another cold front
and northern shortwave on sunday and more thunderstorms.

&&

.AVIATION /18Z Monday THROUGH Saturday/...
Through 18z Tuesday...VFR conditions outside of scattered
thunderstorm activity expected throughout the afternoon and early
evening. Within heavy showers and thunderstorms, MVFR cigs and
vsbys have been observed and expected to continue. Convective
activity will continue throughout this afternoon with some storms
becoming strong to severe producing wind gusts in excess of 45kts,
hail up to one inch, brief periods of heavy rain and frequent
lightning.

Convective activity looks to begin exiting east and weakening
after 00Z/Tuesday. Some showers will develop along cold front as
it moves from north to south southeast between 00z Tue-06z Tue,
diminishing as the night progresses. Winds behind the front will
shift NW behind the front.

Drying trend and diminishing clouds expected after 06Z...with
possible IFR/MVFR fog development mainly at KSLK and KMPV as winds
slacken. Tuesday morning, expect NW flow to continue with VFR
conditions.

Outlook 18z Tuesday through Saturday...

18Z Tue - Thu: VFR under high pressure. Overnight IFR fog
possible each night, especially at KSLK and KMPV.

00Z Fri onward...VFR, though with potential for showers/storms
and brief ifr/mvfr possible.

&&

.MARINE...
As of 345 AM EDT Monday...Those planning to boat on Lake
Champlain (or even the other smaller lakes for that matter) will
need to pay close attention to the weather throughout the day and
be prepared to return to safe harbor in the matter of just a few
minutes. Thunderstorms, some strong to perhaps locally severe,
will develop by the afternoon hours. These storms will easily be
able to produce strong wind gusts in excess of 35 knots, short-
lived higher waves, frequent lightning and perhaps large hail. A
Lake Thunderstorm Advisory is in effect for this afternoon due to
this threat. In addition, south to southwesterly winds will be
rather gusty today, frequently reaching to near 20 knots.
