.WHAT HAS CHANGED...
No significant changes with this forecast package.

.KEY MESSAGES...
1) Scattered to widely scattered showers and thunderstorms are
expected this afternoon. Some storms could be severe, mainly
along and south of Interstate 90.


2) Another round of showers and possible storms is expected
Wednesday night into early Thursday. Severe weather is not
expected with this second round.

.DISCUSSION...
KEY MESSAGE 1...
Main forecast concern today continues to be another round of
showers and storms as a shortwave trough, embedded in west-
northwest flow aloft, approaches during the late morning and
afternoon hours. This feature, combined with a northward
lifting warm front, in a weak to moderately unstable airmass,
will set the stage for another round of storms, some of which
may become severe. As a result, SPC has maintained a Marginal
Risk (Level 1 of 5) for areas along and south of Interstate 90.

Available high-res models to include both the HRRR and 3km NAM,
show developing storms after the 18z timeframe. Fcst soundings
from across the area show steep low-level lapse rates thanks to
temperatures warming into the lower to middle 80s later today.
This combined with increasing moisture advection behind the
warm front, should support MLCAPE values from 1000-1500 J/kg
across the area later today. Despite decent synoptic forcing
with the approaching shortwave, main limiting factor for a more
widespread severe threat appears to be weaker deep layered shear
fields as 0-6km bulk shear values are expected to range from
30-35 kts eastern NY and western New England, while stronger
shear values remain out west across the southern Ontario and
western New York.

Given decent dry air aloft along with steep low-level lapse
rates, the main threat with any storms that approach severe
limits will be damaging wind gusts. That said, a humid airmass
will once again lead to efficient rainfall with any storms, and
WPC has also maintained a Marginal Risk (Level 1 of 4) for the
entire fcst area. Storms should track east and gradually weaken
after the 00z timeframe with loss of daytime heating.

KEY MESSAGE 2...

The next chance for rain will be Wednesday night into Thursday
morning as another shortwave trough and associated cold front
approach the region.  As of right now, precipitation looks to
move in after the 00z Thursday time frame. Given the time of
day, instability looks to remain fairly limited, and thunder
activity should be isolated in nature.

.AVIATION /18Z MONDAY THROUGH SATURDAY/...
Through 18Z Tuesday... VFR conditions prevail across all
terminals through late this afternoon, with light southerly to
southwesterly winds and mid-to-high clouds. There is potential
for scattered thunderstorms late this afternoon into this
evening, generally between 22Z through 03Z, which could bring
brief vis drops to MVFR with strong and variable winds.
Lingering low level moisture and winds weakening to calm and
variable throughout the overnight periods could lead to the
development of radiational mist/fog, particularly at KGFL, KALB,
and KPSF. These terminals could see brief periods of MVFR/IFR
in the early morning hours of Tuesday. Any mist/fog that does
develop will quickly burn off after sunrise, returning all
terminals to VFR conditions with light northwesterly winds
through the end of the TAF period.

Outlook...

Tuesday Night: No Operational Impact. NO SIG WX.
Wednesday: No Operational Impact. NO SIG WX.
Wednesday Night: Low Operational Impact. Slight Chance of SHRA.
Thursday: Moderate Operational Impact. Chance of SHRA.
Thursday Night: Low Operational Impact. Slight Chance of SHRA.
Friday: Low Operational Impact. Breezy. NO SIG WX.
Friday Night: No Operational Impact. NO SIG WX.
Saturday: No Operational Impact. NO SIG WX.
