Day 1...

...Northeast...

There is a low risk for four inches of snow over the Catskills
through tonight as a shortwave trough axis rounds the parent low
over Hudson Bay providing some PVA in a stripe across PA/NY that
is in the right entrance of a southwesterly jet streak moving off
the northeast CONUS. This feature shifts east across southern New
England Monday morning.

The probability of significant ice (0.25-inch or more) is less
than 10 percent.

Days 1-2...

The risk for significant snow (4-inch) or ice (0.25-inch or more)
