Area Forecast Discussion
National Weather Service Burlington VT
342 PM EDT Wed May 24 2017

.SYNOPSIS...
Scattered showers and possibly a thunderstorm are possible
this afternoon mainly over the higher terrain as a weak upper
level disturbance crosses the area. A stronger low pressure area
will move out of the Ohio valley and bring more widespread
rainfall to the North Country Thursday afternoon through Friday.
Today will be the warmest day of the week with highs in the mid
to upper 70s. Clouds, rain, and cool east winds off the
Atlantic will all conspire to keep highs in the 60s Thursday,
and 55 to 60 on Friday.

&&

.NEAR TERM /UNTIL 8 PM THIS EVENING/...
As of 133 PM EDT Wednesday...Going forecast is in good shape.
Did bump up max temps just a bit for today as temps are rising
nicely this morning and should reach the mid 70s this afternoon.

Previous discussion...500 mb vort center moving along Atlantic
coastline in southwest flow aloft as closed low digs into base
of mean trough centered over central Mississippi valley. Surface
low centered off the New Jersey coast moving northeast and set
to cross the benchmark today. Area of rain will remain close to
the low and may brush southern New England coast but remain
outside forecast area. Although this rain will miss us, weak
shortwave trough will cross the area during the day, and
combination of it an weak low level convergence area along with
200-400 j/kg of surface based cape will provide focus for
scattered showers and possible thunder. Pops more widespread
compared to yesterday, but still in chance category in the
mountains and slight chance in the valleys. Any precip will
dissipate toward evening with loss of surface heating.

Today will be the warmest with weak ridging and higher
thickness values. Highs in the 70s.

&&

.SHORT TERM /8 PM THIS EVENING THROUGH FRIDAY/...
As of 440 AM EDT Wednesday...Region remains in southwest flow
tonight and Thursday as 500 mb low deepens over eastern US.
Closed low over the Ohio Valley will shift northeast to the
eastern Great Lakes through Thursday, while a vort lobe swings
through the base of the trough across the gulf states and moves
up the coast Thursday and Thursday night. By Friday the Great
Lakes low fizzles out and the upper low center shifts to the
coastal vort, spinning up a surface low there. For sensible
weather rain will spread from southwest to northeast Thursday
afternoon and continue Thursday night. For Friday better QG
forcing shifts east of the area with the low, however moist
easterly flow at the low levels will keep plenty of moisture
into the area with showery precip tapering off through the day.
Storm total precip for this period 3/4 to 1 inch, with higher
amounts in south & east Vermont.

As the surface low deepens over Long Island late Thursday a
strong low level jet east/southeast jet of 35-45 kts develops
with the potential for wind gusts of 30-45 mph along along the
downslope communities of the western slopes of the Green
Mountains in Chittenden, Addison and Rutland counties. Brief
window for gusty winds late Thursday before more stable maritime
air moves in.

Temperatures will see a cooling trend Thursday and Friday as
heights fall under the upper low & low level temperatures cool
in easterly flow off the Atlantic. Clouds and rain will also
keep any sun at bay. Overnight lows to remain mild however, in
the upper 40s to 50s.

&&

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
As of 340 PM EDT Wednesday...The synoptic pattern will be
shifting towards a more pleasant weekend as vertically stacked
low pressure system will be pulling off the New England
coastline. This leaves a few scattered showers over the eastern
portion of Vermont as the moisture will be decreasing through
the evening hours. The more welcomed portion of the forecast
will be the high pressure that builds in for Memorial Day
weekend. As ridging occurs at the surface there may be a stray
shower or two but otherwise we can expect highs in the upper 60s
to lower 70s with partly cloudy skies with a few breaks in the
that areal coverage.

The latest trends in the guidance has been to slow down how
quickly the next system is to move into the region. In the broad
sense, an upper level low pressure system will track west of
the Great Lakes and lift a warm front through the North Country
and then later on will swing a cold front through. The timing on
this has been even further delayed such that we may get through
much of Sunday with quiet weather and nice conditions to be
outdoors or perhaps going for a run.

Towards Sunday evening and into Monday morning, expect that
warm front to lift north and bring a chance for scattered
showers into Monday. By Monday mid-morning early afternoon a
pre- frontal trough will swing through with shortwave energy
aloft and bring showers with perhaps some embedded
thunderstorms. The GFS depicts decent instability with marginal
elevated instability along with decent 0-6km shear and moderate
lapse rates. So the idea of some showers with embedded
thunderstorms looks good based on the 12z guidance timing.
Heading into the rest of the mid week we should see a break on
Tuesday before the actual front swings through on Wednesday
renewing our chances for showers.

Temps through the period will be depend on the timing of the
fronts but the general idea is upper 60s to lower 70s for high
and lows starting off in the upper 40s over the weekend and
gradually warming to the low to mid 50s by mid week.
