Next chances for some accumulating snows..
As the cold front moves through on Tuesday morning, snow showers
will overspread the area, with continued lake enhancement
transitioning to lake effect Tuesday afternoon through Tuesday night
southeast of the lakes. An upper level trough axis will be over the
area on Tuesday afternoon and move through by the evening.
Widespread snow of around an inch is possible on Tuesday, with
additional light snow amounts from the lake effect. Highs on Tuesday
will occur in the late morning or early afternoon and reach the low
to mid 30s. Low temperatures on Tuesday night will be in the teens
over the higher terrain east of Lake Ontario, and in the low to mid
20s elsewhere.
A clipper system will dive southeast across the northern Great Lakes
and to the St. Lawrence Valley by mid morning on Wednesday, and with
it bring another cold front that will usher in the coldest air since
last winter. The clipper will bring with it some general light
synoptic snow, with some light lake effect snow following the
general light snow. Snow chances overall will increase from west to
east toward the Eastern Lake Ontario area as the best synoptic
moisture and forcing will be in place there with the clipper passing
directly overhead. As the clipper exits the area, a large Arctic
high centered over Ontario will move southeast toward the upper
Great Lakes
