A strong "Colorado Low" is currently moving northeast through the Ohio Valley, spreading very heavy snow across several major metropolitan areas, including St. Louis, Chicago, Detroit, Pittsburgh, and Buffalo. Total snowfall accumulations of well over a foot will be possible from Lower Michigan east to the Northeast, as the Colorado Low transitions into a Nor'Easter off the coast of New England by tomorrow evening. As the low intensifies, strong winds will create blizzard conditions across these areas tomorrow, with considerable blowing and drifting of the snow. Meanwhile, tornadoes have been reported in the warm sector of this system across the FL Panhandle and Georgia, with a tornado watch in effect across parts of Georgia and Florida this evening.
Radar Summary:
Shown below is the radar loop from around 9:00 - 10:00 pm CST, showing the very heavy snow associated with the deformation zone from St. Louis through Lower Michigan, the warm advection-related snow in the Northeast, and the severe convection in the Southeast.
Model Data:
The GFS loop of forecast MSLP from Saturday evening through Monday evening shows the strengthening Colorado Low as it moves through the Ohio River Valley, and transitions to a strong Nor'Easter just off the coast of New England by Sunday evening. Note how the Nor'Easter strengthens to below 970 mb by Monday, as the surface low explodes along the coastal baroclinic zone.
Winter Storm Watches, Warnings, and MDs:
Winter storm warnings are in effect from Missouri through central/northern Illinois, the Great Lakes Region, and New England, where over a foot of snow will fall through the early part of next week. Many of these areas will be upgraded to blizzard warnings as winds pick up to greater than 40 mph in gusts..especially in New England by Sunday night through Monday. Evening flood watches are in effect for the Ohio River Valley, where heavy snow fell earlier today before changing to rain. INCREDIBLE WEATHER EVENT!!
Several mesoscale discussions have been issued for both winter weather and the severe weather in the warm sector. Shown below is one issued for intense snowfall rates of an inch/hour or greater across central/northern IL extending into northwest IN and Lower MI. In addition to intense snowfall rates, the slow-moving nature of this system is also a huge factor for the excessive snowfall amounts.
Severe Weather Watches, Warnings, and MDs:
As is often the case these strong winter season storm systems, supercells and tornadoes are common in the warm sector across the Gulf Coast and Southeast U.S., given the presence of a strong low-level jet and ample moisture pumped northward via the rapidly strengthening storm system. Two damaging tornadoes have been reported so far, one in Santa Rosa County, FL earlier today, and another more recently in Wilcox County, GA, where a mobile home was severely damaged. As the strong cold front moves east across GA and FL, more damaging tornadoes are a realistic possibility as the night progresses. Stay tuned for updates as this intense winter storm system unfolds!

Reed, please ban smt for saying that there is snow in MI.
:D
... Okay, okay, I've gotten completely out of control with the banning requests. Sorry. I promise to stop.
*** As soon as I typed the period on the end of that ^^, a huge gust of wind blew our giant birdseed box off of our back porch. It weighs about 40-50 lbs; the hinged lid came up a little bit & acted like a sail. It sounded like part of our roof was coming off! AAAAA!!!!! It's nasty out there!
Have fun watching the radar, Donny. Hopefully ya don't end up having to call anyone!
Marc up in Maine ought to be getting some major snow footage for you, Reed.

wow thx Don! sound kinda bad for nyc. I remember getting trapped in a snowstorm in midtown manhatten once. I didnt realize how much that sucked, cause I thought, you re in a city for gods sake ofcourse you can seek shelter easely, but all the buildings were big companies, no bars etc to run in. after my hair was frozen I realized I needed a taxi. ofcourse I wasnt the only one thinking that. I finally got into one and thats when this beautifull business lady janked* the taxi door open and pretty much ordered me out. lol obviously I did not comply. (lol check out the def. of janked maybe i spelled it wrong but well...)
yanked lol and your welcome
hahahaheheh I c...hey don u know i got a chat on: insaneweather.com come over for a chat if you feel like it.
It's freezing rain here, they took away OUR SNOW........AHHHHHHH. Still holding out some hope for tomorrow though, and to think I was going to MI on Monday! Guess another trip is called off.

I texted my internet friend in Gainesville. She said everything was fine there. Hopefully around her hometown Tallahasseee (its too early in the morning, or late at night, can't spell lol) everything's ok too. If I hear any updates from her I'll let you know what she says.

Yup its coming there Caro. Im about to get crushed by this and i have to work today.
Environment Canada is saying this Winter Storm could produce anywhere from 20-50 cm of snow today.
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA

Southern Ontario Caro.
and what is the situation down there?
There are reports of overturned cars, blown off roofs and power outages in Pasco County Florida.
thanks for those web cam links guys.. Looks like the Northeast U.S. and adjacent areas of Southern Ontario/Quebec Provinces are really getn socked with snow and wind Today..
A Winter Storm Warning remains in effect until 7 am EST Monday.
Snow will become heavy at times today after sunrise. The snow
will taper off to a period of light snow late this morning into
the afternoon... before redeveloping by late afternoon. The snow
may mix with sleet at times across the Champlain Valley and the
northern Adirondacks... before changing back to all snow late this
afternoon. The snow will continue into the evening hours before
tapering off early Monday morning. Total storm accumulations of 12
to 18 inches can be expected by Monday morning. Isolated amounts
up to 20 inches are possible in the northern Adirondacks and St.
Lawrence Valley.
The combination of falling snow and gusty winds will cause
blowing and drifting snow... which will result in very hazardous
traveling conditions on Sunday into early Monday morning.
...I have to warm up my shovel...
here's another cool link for webcams in the province of quebec... Montreal will recieve the "best" of this snowstorm...

great clips caro!!!!
That was quite a snowstorm, Caro! Is it still snowing there or is it just cold and windy?
Boy that N.E. storm is really wrapping up This Evening. Water vapor satellite of this storm looks super cool! 977 mb as of 7 PM EST off the New England coast. Impressive pressure falls of 8+mb/2hours currently over Northern New England, incredible! Great pics Caro!
Hi Heidi! Winds are calm and there's just light snow falling down...we had 30cm (12 inches) since this mornig and between 5 and 10 more are expected for tonight.
5 to 10 cm not inches...sorry
I've almost finished my video "montage" and I'll put it on youtube as soon as I can...
Euro model has an interesting storm for next weekend. 12z run from This Evening has a deepening low heading NE out of the Southern Plains, toward Chicago Illinois by Sunday Morning. Parts of Kansas, Nebraska, Iowa, Wisconsin, and possibly parts of Minnesota and Upper Michigan could be in for a winter storm next weekend if this verifies. Interesting to note that the long range models have been showing a storm for quite some time the weekend leading up to Christmas. Just the storm track and intensity has changed from run to run, but that's not unusual
