.SYNOPSIS...
A large upper level low will shift southeast today, which along
with a cold front will produce scattered showers and
thunderstorms. Cooler and drier weather will move in for July
4th, with pleasant conditions expected. A warming trend starts
on Saturday, with highs back into the 90s by early next week.

.NEAR TERM /THROUGH FRIDAY/...
As of 653 AM EDT Thursday...Did an update this morning to
account for showers which have already formed. Used HRRR and
HREF blended into NBM to show coverage of morning showers, and
additional showers this afternoon. Previous discussion follows.

Showers and thunderstorms are expected across our area today as
an upper level trough crosses the region, as well as a surface
cold front dropping south across our area. The frontal passage
will occur early in the day, and winds will be westerly, then
northwesterly behind the front. SPC has expanded their Day 1
slight risk to include more of our area. Pretty efficient
daytime heating before the frontal passage will lead to maximum
temperatures ranging from the lower 80s in the Champlain and
Connecticut river valleys, but only ranging through the 70s in
northern New York where the frontal passage occurs earlier in
the day. Deep layer shear is favorable as winds will be fairly
weak at the surface out of the west to northwest, and an upper
level jet passes overhead within base of upper level trough.
Damaging winds will be the main threat with any organized
thunderstorms that develop, but some hail will also be possible
given the shear profiles. Timing of the front being early in the
day could limit severe potential. Moisture is somewhat limited
with mainly westerly flow in place across the region. HRRR and
NAM3 both show 2 areas of convection associated with multiple
surface troughs crossing the area, first this morning and then a
second area of showers behind the front this afternoon, the
HRRR is the more robust solution out of the two. Even if storms
do not become strong/severe, they will still be capable of
producing deadly lightning. Timing for shower and thunderstorm
activity has been bumped earlier, mainly 1 pm to 7 pm. Some
showers may linger beyond 7 pm. If you have outdoor plans,
please stay weather aware and follow the latest forecast
updates. When there are peaks of sun today, expect hazy
conditions as some Canadian wildfire smoke will be in the upper
levels. Quieter and cooler weather is then expected for both
tonight and Friday.

.SHORT TERM /FRIDAY NIGHT THROUGH SATURDAY NIGHT/...
As of 200 AM EDT Thursday...A pleasant stretch of weather is
expected for the first half of the weekend. High pressure will
continue to build into the region over the weekend, bringing dry
weather and a warming temperature trend. High temperatures
Saturday afternoon look to be seasonably warm, climbing into the
low to mid 80s with dewpoints in the 50s. These temperatures
and partly sunny skies will make for a rather enjoyable
Saturday. Southerly flow will begin to usher in more humid air,
with mild overnight lows only dropping into the 60s to near 70
for Saturday night.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
As of 200 AM EDT Thursday...Surface high pressure and ridging
aloft will continue to bring a period dry weather and increasing
heat for Sunday. Southerly flow will continue to advect a more
humid airmass into the region. High temperatures Sunday
afternoon look to climb into the upper 80s to mid 90s across the
region, feeling quite uncomfortable with the increased moisture
and dewpoints in the 60s. The heat will likely linger into
Monday, especially across southern portions of the forecast area
as a slow moving cold front approaches from the north. There is
still plenty of uncertainty as to how quickly this feature will
progress across the region, bringing chances for showers and
thunderstorms, especially Monday night. This feature will help
provide relief from the heat, with more seasonable conditions
expected heading into the middle of next week.

&&

.AVIATION /12Z THURSDAY THROUGH MONDAY/...
Through 12Z Friday...Scattered showers and thunderstorms will
lower visibilities today and have mainly used PROB30 groups to
account for this. Cloud cover is expected to increase today,
though ceilings should stay generally 4500 feet above ground
level or higher. Rain shower chances increase 12Z-18Z with
highest confidence of a shower or even a thunderstorm 18Z
onward. Depending on where these showers or thunderstorms occur,
visibilities could be reduced to lower than forecast. Winds are
expected to turn more northwesterly today 5-10 knots with gusts
up to 20 knots possible, potentially even higher in any
thunderstorms. Will once again have potential for fog formation
overnight, especially terminals that have rainfall today.


Outlook...

Independence Day: VFR. NO SIG WX.
Friday Night: VFR. NO SIG WX.
Saturday: VFR. NO SIG WX.
Saturday Night: VFR. NO SIG WX.
Sunday: VFR. Slight chance SHRA, Slight chance TSRA.
Sunday Night: VFR. Slight chance SHRA, Slight chance TSRA.
Monday: Mainly VFR, with local MVFR possible. Chance SHRA, Chance
TSRA.
