 For Your Viewing Pleasure --- I just printed a copy of this for posterity.  Looks like this visit by the polar vortex will be history-making.

 

---Also.....Hi Zak!  I hope you are back again.  We've all missed you and your posts A LOT!

***Record-breaking cold expected over much of Eastern U.S.***

***Snow and wintry mix with a developing surface low***

***Most of the Western U.S. will have quiet weather***

The coldest weather in years will be making its presence known from the
Upper Midwest to the Mid-Atlantic region for the beginning of the work
week.  The polar vortex, a mid-upper level cyclonic feature normally
present over northern Canada, will be displaced unusually far to the south
over the northern Great Lakes and southern Ontario.  Owing to the deep
layer of the cold air mass, this will provide for an incredibly strong
surge of bitterly cold Arctic Air along with gusty winds.  The Upper
Midwest will be affected first by Saturday night, and the brutal
conditions will continue pushing southeastward to the Ohio Valley and
Mid-South by Monday, and to the Northeast and Mid-Atlantic by Tuesday. 
Particularly noteworthy will be the extreme wind chills and nearly
unheard-of daytime highs that are forecast.  Wind chill warnings are in
effect for many areas with wind chills on the order of -30 to -50 degrees
expected!  Afternoon highs on Monday for parts of the Midwest states and
the Ohio Valley will fail to reach zero degrees!  The good news is that it
will be a quick event, and moderating temperatures are expected to return
by Wednesday.

Ahead of the Arctic blast, a developing surface low along the cold front
will result in widespread snow developing from Missouri to the Ohio Valley
and into the Great Lakes.  Areas that have persistent snow bands may
receive on the order of 6 to 12 inches of snow, with locally higher
amounts.  Winter storm warnings are in effect as a result.  A light wintry
mix of freezing drizzle and perhaps some sleet is possible from parts of
the Mid-Atlantic region into New England on Sunday as warmer air overrides
colder air near the ground.  A transition to rain is expected for the I-95
corridor before the front arrives.

Elsewhere, with the exception of some orographically enhanced snow showers
across the central and northern Rockies, the majority of the Western U.S.
can expect relatively pleasant weather conditions through Monday.

Despite a fairly solid cloud deck, I'm down to 23.4 already.

 

I'm down to 14 already. I'm sure with WAA it will start to rise at some point, but the fact is we're pretty low already, and unless the WAA is strong, it will take awhile to get to 32 tomorrow.

 

Oh definitely, with the snow pack and cold ground it won't be hard to ice up surfaces with an air temp that could be a degree or two above freezing. Could be a struggle to get above freezing for awhile as well. 

 

Side roads in my area are plowed, but still snow packed. While the main roads may be ok, the snow packed ones are going to be just flat out nasty.

Yea, I hate to hype things up but even down here the side and back roads have snow pack or slush still on them. That freeze up and a little drizzle will ice up on them. Its Sunday morn so not much traffic but still. When the drunks leave the bars after the eagles game around here should be fun with the refreeze tonight.
