Nice little burst of winter at the moment, nothing sticking of course..

A mature cyclone over the Upper Midwest Saturday night will track
east while high pressure over our region will begrudgingly give way
to this system. Conditions will slowly deteriorate as the warm front
pushes slowly into Western NY overnight. The GFS/ECMWF have for the
past couple of days been in generally agreement with this feature.
However, there still remains some forecast challenges with how fast
the push of warm air aloft moves in across the region. The GFS is
rather fast and much warmer aloft, which would quickly transition P-
type over from snow to freezing rain or plain rain. On the other
hand, the ECMWF sounding profiles are much colder with a slower
transition from southwest to Northeast across Western NY into the
Finger Lakes. The North Country may not even see a transition if the
colder solution were to come to fruition. For now, have gone with a
blend of the two solutions at this point with most locals seeing a
transition of P-type. Again, the lone exception will be across our
far northern counties of Oswego, Jefferson, and Lewis counties where
it may stay all snow. While this won`t be a significant event, any
amount of mixed precipitation will likely make for tricky travel
keeping in mind that it will be a busy travel weekend.
Sunday, the weakening low will slowly track east reaching northern
Ohio by Sunday night. While this occurs, a secondary low will
develop off the Delmarva coast and track northeast along the coast
nearing Long Island Sunday night. On the backside, once again colder
air will wrap back in along with some additional moisture backing
across our far eastern counties. While it doesn`t appear at this
point too add a significant amount of precipitation, there may
be some minor accumulations depending on area surface temperatures.
