It looks like their temperatures stay below normal right through Friday.

Not only is much of the country under winter weather advisories or winter storm warnings, but also cold weather advisories and cold weather warnings.

Many locations in the Ohio River Valley, the mid-Mississippi River Valley, mid-Atlantic, and also the Northeast will wake up tomorrow to wind chills that are anywhere from 10 to 20 below.

And this cold air looks to remain in place through the upcoming weekend.

And then it spreads quickly off towards the east.

We're going to see it moving into the mid-Atlantic states by late in the day tomorrow.

It's into the New York City area by early Sunday morning and then into Boston Sunday afternoon.

It's going to be a sizable snowfall.

Right now, it looks like the district of Baltimore pick up 8 to 12 inches of snow.

There will be some sleet and freezing rain that mixes in a Sunday afternoon, Sunday evening.

That may hold the accumulations down there.

Also, as we look on up to the New York City area, there may be some mixing, especially south of New York City.

But it still looks like an 8 to 14 inch snowfall for the New York area.

Southern New England, they could be the jackpot area.

Right now, it looks like Boston's looking at 10 to 16 inches.

And there could be some places outside of Boston that pick up a foot and a half of snow by the time it's winding down Monday evening.

That's Bloomberg meteorologist Rob Carroll.

We have a big force going toward Iran.

I'd rather not see anything happen, but we're watching them very closely.

Right now we're ready for 36 straight hours of snowfall.
