BUF
.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
High pressure will move off the New England coast Sunday, with a
ridge extending back across New York State and New England
providing a dry finish to the weekend. Temperatures will be
significantly warmer than on Saturday after a cold start Sunday
morning, however still some 5-10 degrees below average for mid
January.
Our attention then turns to a potential significant synoptic system.
Confidence continues to increase for a Nor`Easter to impact our area
from Sunday night into Monday. 12Z ECMWF/GFS/Canadian all have the
center of an area of deepening low pressure moving NNE directly over
central/eastern NY late Sunday night and Monday. Given the increased
confidence, us and surrounding offices have stepped up PoPs into the
Lkly range from central and eastern PA up through central and
eastern NY during this timeframe. If this system tracks to far
inland p-type could become an issue, mainly across eastern areas at
this point, however will keep precipitation as all snow for now this
far out.
Some lake effect and upslope snows will develop Monday night lasting
into the day on Tuesday under WNW/NW flow in the wake of the
departing storm system. Any lingering lake effect snow showers will
weaken and sweep from south to north as winds back to the southwest
Tuesday night ahead of a Clipper type system moving into the upper
Great Lakes. This will bring the next chance for a light synoptic
snow to western and northcentral NY mid week.
