.DISCUSSION...
KEY MESSAGE 1...Rounds of showers and a few isolated thunderstorms
through this evening, then some patchy fog and low clouds overnight
through early Friday morning.

The widespread rain from earlier today is exiting stage right across
eastern NY early this evening. A few more scattered showers are
developing across Western NY early this evening. The best coverage
of showers through the first half of tonight will be east of Lake
Ontario where the best large scale ascent and moisture is found.
Farther west across Western NY and the Finger Lakes, a few scattered
showers will continue this evening, along with a chance of a few
widely scattered thunderstorms from both homegrown activity and the
weakening remnants of upstream convection arriving from the west.

What little severe weather risk there was today is even lower now,
given the impacts of extensive clouds and rain today on stability.
Modestly unstable air is attempting to develop and advect into
Western NY early this evening, but the loss of daytime heating will
quickly end this modest destabilization. There is more than adequate
deep layer shear available, but the lack of instability and poor
lapse rates will likely be too much to overcome.

Overnight, any remaining showers will mostly end from west to east,
with a few spotty showers possibly lingering east of Lake Ontario
through Friday morning. High-res model guidance and statistical
guidance suggests an area of low stratus and fog may develop across
Western NY late tonight through early Friday morning, especially
across the Niagara Frontier. Added areas of fog to account for this
potential.

KEY MESSAGE 2...Trending warmer this weekend and into next week.

A mid to upper level ridge will begin to build across the Great
Lakes this weekend before shifting east into the Northeastern
portions of the CONUS through next week. Temperatures will gradually
increase by the end of the weekend and into early next week. Heat
and humidity will then increase further through the middle of next
week, which may result in the potential for heat-related headlines
as the risk for dangerous heat indices increase. There continues to
be some spread between ensemble members for this period of warmer
weather. This is likely due to the potential for scattered showers
and thunderstorm both Tuesday and Wednesday that could help bring
some short-term relief from the heat.

.AVIATION /00Z FRIDAY THROUGH TUESDAY/...
The widespread rain from earlier today is exiting stage right across
eastern NY early this evening. A few more scattered showers are
developing across Western NY early this evening. The best coverage
of showers through the first half of tonight will be east of Lake
Ontario where the best large scale ascent and moisture is found.
Farther west across Western NY and the Finger Lakes, a few scattered
showers will continue this evening, along with a chance of a few
widely scattered thunderstorms from both homegrown activity and the
weakening remnants of upstream convection arriving from the west.
Mainly VFR conditions will prevail through the first half of the
night, with any CIG/VSBY restrictions localized to spotty heavier
showers.

Overnight, any remaining showers will mostly end from west to east,
with a few spotty showers possibly lingering east of Lake Ontario
through Friday morning. High-res model guidance and statistical
guidance suggests an area of low stratus and fog may develop across
the region late tonight through Friday morning with areas of
MVFR/IFR CIGS. The best chance of fog appears to be across the
Niagara Frontier including KBUF and KIAG with areas of IFR VSBY
possible.

The fog and low stratus will mix out by mid to late morning with a
return to VFR conditions for the afternoon. Friday will be mainly
dry, with any showers and thunderstorms limited to the Saint
Lawrence Valley and northern Adirondacks mainly east and north of
KART.

Outlook...

Friday night through Saturday...VFR in most areas. Some brief/local
restrictions possible in scattered showers and thunderstorms across
the North Country and Southern Tier. Patchy fog and local IFR
possible late Friday night through early Saturday morning.

Sunday through Tuesday...Mainly VFR.

.MARINE...
Winds and waves will remain well below Small Craft Advisory
criteria Friday and into the weekend with a weak pressure
gradient in place across the lower Great Lakes.
