.WHAT HAS CHANGED...
Added rain shower chances through the early evening for the
Thruway corridor for lake effect rain. Fog was added to all the
deeper valleys across the Twin Tiers of NY and PA tonight and
tomorrow night.

&&

.KEY MESSAGES...
1) High pressure brings sunny and seasonable weather for
Thursday through Saturday, with areas of morning fog.

2) Shower and chances for thunderstorms return to the forecast
Sunday into early next week as the next upper level trough moves
into the area.

.DISCUSSION...
KEY MESSAGE 1...

Water vapor imagery early this afternoon shows a pair of upper
level lows in Southern Canada and very dry air advecting into
the northeast on the South side of the lows. Given the cooler
air mass aloft and warm waters on Lake Ontario, there have been
some lake effect rain showers and these will persist into the
early evening when the cold air advection weakens. Surface high
pressure is building in and with nights starting to get a little
longer and some boundary layer moisture in place, valley fog
will likely develop in the overnight hours, lasting through
sunrise, across the Twin Tiers of NY and PA.

KEY MESSAGE 2...

The weather pattern will turn more active late in the weekend and
into early next week as a broad upper level trough digs into the
Northeast US. With a large ridge out across the intermountain
west, NW flow will dominate in the Northeast under the trough.
This will maintain some higher wind shear, with ensemble bulk
shear means near 25 to 35 knots Monday through Wednesday. PWATs
will be up near or over 1.5 inches and mean CAPE getting up near
500 J/kg indicates there will be moisture and fuel. Once again
it is looking like an active severe pattern, though right now
CAPE and Shear means are lower than the last few weeks.

&&

.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
SYR and RME will have to deal with some lake effect rain showers
through the early evening but all other terminals have become
VFR. High pressure building in will cause winds to fall off and
become nearly calm after 0Z. This is favorable conditions for
fog, with ELM likely seeing fog develop near the terminal. RME
may also see fog because of the rain showers ongoing but
confidence was not there as lingering VFR stratus may prevent
cooling. All terminals are expected to be VFR tomorrow after
12Z.

Outlook:

Thursday through Saturday...Mainly VFR; morning fog at KELM may
result in restrictions.

Sunday into Monday...Scattered afternoon showers and/or
thunderstorms may result in occasional restrictions.

.BGM WATCHES/WARNINGS/ADVISORIES...
PA...None.
NY...None.
