0827 AM CST Sun Jan 27 2019

Areas affected...portions of central NY into central PA

Concerning...Heavy snow 

Valid 271427Z - 272030Z

SUMMARY...Snow squalls associated with a cold front tracking
eastward across the area will bring brief periods of moderate to
heavy snow and gusty winds. Conditions may deteriorate rapidly, with
lowered visibility, over short distances as the snow bands track
east/northeast.

DISCUSSION...A surface low was located just north of Lake Ontario
this morning, with a trailing cold front extending south/southwest
from near Watertown NY into western PA. Near the front, narrow snow
bands will produce brief periods of moderate to heavy snow as the
squalls shift east/northeast this morning into this afternoon. While
a tight pressure gradient is leading to some gusty winds
region-wide, wind speeds may increase further as the snow squalls
and cold front pass. Some locations have gusted to near 30kt with
the squalls. These brief bursts of heavier snow and strong winds
will lead to reduced visibility. Conditions may change quickly over
short distances, especially if traveling on east-west oriented
roadways. The snow squalls are expected to persist into the
afternoon as the cold front continues to shift eastward across the
region.
