Buffalo:
Attention turns to the next system that will ride along the cold
front near western and north central NY. Strong, southwest flow will
supply abundant Gulf of Mexico moisture into the eastern third of
the Lower 48. Ensemble forecast systems are showing signals of PWATS
of +2 SD above normal Friday to Saturday. Guidance is similar in
tracking the deepening low along the cold front from the Central
Appalachians to Long Island. While this can keep us on the cold,
snowy side, the 850mb low may be further to the northwest. This may
bring enough warmer air aloft into the region causing a wintry
mix Saturday to Saturday night. A dry, cold will likely move
into the region behind this system with little lake response
expected.
Binghamton:
The low pressure system passing by well to the north then drags
a cold front into the region later Friday. This then becomes a
stationary boundary...with a large temperature gradient developing.
Significant model differences remain for the weekend...but
guidance does agree on some points. The overall set up is there
for strong moisture transport from the Gulf of Mexico on Saturday.
This could lead to 1-2+ inches of QPF across the region. However,
there will also be an arctic Canadian high pressure center north
of Lake Superior and into Quebec. This will try to push low
level cold air down into the region at the same time; along and
north of the stationary boundary. Depending on the exact low
track (west, right over us or southeast of here) will have huge
implications for what types of weather we see this weekend.
These exact details are yet to be resolved...but it`s beginning
to look like parts of the area could see impacts...whether it`s
from ice, snow, heavy rains (or a combination of the three)
remains to be seen. Overall, with such a strong high pressure
center north, one would expect the system to perhaps shift a
little further south; bringing more of wintry mix to the area.
Please be sure to check back as will continue to monitor and
update forecasts for the weekend.
