Lake Effect Snow Event for Upstate NY (12-15-09)

Discussion...
Most areas should only see Advisory-level amounts, with a few localized amounts exceeding 7" by the time everything winds down on Thursday. Best chance of this is likely to be in the vicinity of I-90 in North Central NY in and around the Syracuse Metro. Lesser amounts of 3-4" could be realized in the Finger Lakes region between now and Wednesday Morning when the flow is more straight out the Northwest before activity lifts to the north and east for much of the day on Wednesday. There should be some enhancement off the Finger Lakes overnight Tonight, which could bring accumulating snow to parts of the Northern Tier of PA in Bradford/Susquehanna Counties, but generally no more than a localized inch or two, and mainly in northern towns.

Elsewhere, just a general 1-3" across much of Western NY into Northwestern PA with the passage of the current front as well as from snow squalls/showers traversing thru off Lake Erie. Best area for accumulating snow off Lake Erie should be over the ridge from interior Erie County PA thru Chautauqua/Erie Counties in Western NY, where localized amounts up to 7" or so could fall by Thursday Morning.
