Sunday night...the cold front noted above should either by just
about overhead by nightfall or quickly moving east through WNY and
CNY. Dry and cooler air will follow along with diminishing winds.
However, the next system will also be rapidly approaching, with a
renewed chance for precipitation by daybreak Monday.
&&
.LONG TERM /MONDAY THROUGH WEDNESDAY/...
Slowly gaining forecast confidence with the next system for the
start next week as latest model guidance packages are trending
toward more of a consensus. Current thinking with this system is the
stalled frontal boundary from the previous low, will stall southeast
of the region (somewhere between the Catskill Mountains and the
Eastern Seaboard). As noted in previous scenarios,this set up would
support an all snow scenario however precipitation type still
remains of question at this time. Now, arrival time of the cold air
will become the deciding factor of precipitation type. This being
said, while some discrepancies continue to lie between the different
model guidance packages the overall trend has the cold air starting
to arrive Monday morning across the northern portions of the area.
Cold air will continue to advect southward across the region
throughout the rest of the day Monday and Monday Night. What this
boils down to, is a mishmash of precipitation types, with mainly
snow across the North Country, a mix of snow and rain across most of
the CWA, and plain rain across the Southern Tier through out the
daytime Monday. Then, with the system sliding by to the southeast of
the region and as nightfall with cold air continuing to advect in
all precipitation will switch over to be just snow Monday night.
