- light rain early in the week

- Arctic air with lake effect snow showers mid-week

- clipper with light snow end of the week


Discussion...(this evening through next saturday)
issued at 111 PM EST Sat Dec 7 2019

Fairly tranquil pattern continues next couple days with a weak
clipper bringing some light rain Sunday night and Monday. This
will transition to snow on Tuesday as Arctic front moves through.
Lake effect snow showers expected in west flow regime by Tuesday
night through Wednesday. Accumulations will be limited by 5 kft
inversion heights but west flow should bring snow inland and a
general 2 to 4 inches can be expected west of US.131 by late

Sfc high builds in Wednesday night and we can expect lake effect
to end with some clearing. Sub zero readings could occur in the
cold hollows Thursday morning if skies completely clear.

A clipper could bring some light snow at the end of the week or
next weekend. There is some ensemble support for a southern
stream moisture also being drawn north, so it will be interesting
to see how this evolves in the next few days.
