.DISCUSSION...
Key Message 1...Smoke from active wildfires across south-central
Canada is expected to impact our region through at least tonight,
and may linger into Friday.

A west-northwest flow aloft will continue to support a considerable
amount of smoke from Canadian wildfires across the eastern Great
Lakes region through tonight, possibly lingering across the region
Friday. Hazy skies are expected with reduced visibility at times due
to the smoke. Surface high pressure will move across the Great Lakes
region through Friday. This will maintain dry weather across the
forecast area. The HRRR model and RRFS show vertically integrated
smoke decreasing across north-central NY tonight indicating
improving conditions. Smoke may move back into the area Friday.

Smoke is limiting heating during the day and maximum temperatures
were knocked down 5-10 degrees today, and a few degrees Friday. High
temperatures are expected to reach the upper 70s to low 80s today.

Key Message 2...Unsettled weather returns this weekend, with chances
of showers and thunderstorms increasing Friday night and Saturday.

A shortwave trough will move across the Great Lakes region Saturday
while a surface low deepens out ahead of it. This anomalously deep
low for July will also have anomalously high PWATs associated with
it. A deep southerly flow will advect moisture into the region and
showers and a few thunderstorms are possible Saturday through
Saturday night. Increasing instability and a modest wind field
may support a few strong thunderstorms.

&&

.AVIATION /14Z THURSDAY THROUGH MONDAY/...
Smoke from Canadian wildfires will continue to impact the region
through tonight. Upstream observations show visibility less than
3SM. Hazy skies and intermittent periods of MVFR/IFR due to smoke
are expected at the terminals. Model guidance shows smoke moving
out of KART region for a brief period tonight, before moving
back into the region Friday.

A west-northwest wind will increase to 10-15 knots this afternoon.
Winds will become variable tonight.

Outlook...

Friday...Mainly VFR, but smoke is possible.

Friday night through Saturday night...Restrictions likely in
periodic showers and thunderstorms.

Sunday and Monday...Mainly fair weather and VFR expected.

&&

.MARINE...
A light west-northwest wind will persist on the lower Great Lakes
through tonight. Westerly winds will freshen Thursday and a short
period of Small Craft conditions is possible on the eastern end
of Lake Ontario Thursday afternoon and evening.

Smoke from Canadian wildfires may result in periods of reduced
visibility on the lower Great Lakes through Friday.
