.DISCUSSION...
Key Message 1...Day to day warming continues, with fair weather
today, small chance for showers Saturday.

A broad area of surface high pressure is centered across our region
this morning, with light winds and Southern Tier valleys filling
with fog.

This feature will maintain fair weather with sunny skies today, with
a partly to mostly sunny sky Saturday as a little mid level moisture
sneaks northward from OH/PA. A spot shower or thunderstorm will be
possible along a Lake Erie lake breeze circulation Saturday
afternoon, but overall much of our region will remain dry.

Highs in the lower 80s today will become mid 80s for Saturday.
Dewpoints, however, will remain relatively cool through Saturday,
with values only nearing 60F, resulting in a not so humid airmass.

Key Message 2...Unsettled weather returns Sunday and into the
beginning of the new work week.

Several convective shortwave troughs cresting a Rockies/Plains ridge
of high pressure combined with the deepening upper level low near
Hudson Bay will return unsettled weather to our region by Sunday.

Southerly flow behind the recently departed surface high pressure
system will advect deeper moisture (increasing humidity) across the
eastern Great Lakes with Pwat values reaching 1.5 inches or greater.

Building instability across WNY will encourage convection through
the day with scattered showers and thunderstorms developing,
especially along lake breeze boundaries. Additional shortwave
troughs within a northwest flow will maintain showers and
thunderstorms, especially during the peak heating of the day, across
our region Monday and into middle portion of next week.

It should be noted that there will be a good deal of time rain-free
early next week, and the uneven coverage of convection will allow
for some areas to be poured upon while other areas remain dry.

For severe potential, northwest flow can be a direction that can be
an active pattern for localized severe thunderstorm development
across the Lower Great Lakes. For now, the core of the LLJ and
greater 0-6km bulk shear magnitudes appears to be to our west and
south, which may limit the severe potential for our region.

.AVIATION /12Z FRIDAY THROUGH TUESDAY/...
For the 12Z TAFs VFR flight conditions are found and these
conditions are expected to continue through most if not all of
the TAF cycle with a light wind courtesy of an area of surface
high pressure over our region.

A stronger top of the boundary layer wind flow tonight will limit
the expansion of any valley fog across the KJHW airfield.

Outlook...

Saturday...Mainly VFR. A small chance for a shower or thunderstorm
near KJHW in the afternoon.

Sunday...VFR/MVFR with a chance for showers/thunderstorms, mainly in
the afternoon.

Monday...VFR/MVFR with showers and thunderstorms likely.

&&

.MARINE...
A broad area of high pressure over the Lower Great Lakes this
morning will ease to New England by tomorrow, and maintain light
winds and minimal waves on the Lakes through the weekend.
