Wintery Weekend on Tap..Sloppy Saturday and Soaking Sunday.

But first-- Today. 

Similar to Saturday, Strong cold front approaches the air and because it's such an extreme cold blast, there is a good bit of energy tied into it so we should see a line of snow squalls rocket through with 15 to 45 minute blasts of snow.  Could be a coating and in an extreme case an inch or two is possible. Timing will stink because it will be mid to late afternoon.

The Cold...

Tomorrow morning will be brutal with temps down around 5 degrees and windchills -5 to -20. UGLY and the kids won't have school. Friday AM will have CALM winds, but literal temps will be 0 to -10.

The Snow.

The details are slowly coming into focus, but this weekend won't be good. We'll have that cold air sitting in place and a very wet system approaching our area. Due to the lack of blocking (Famed -NAO) I've mentioned, this storm again will eventually be able to dislodge the cold air and we may hit for the precipitation cycle when all is said and done.

Highlights as of now--

By noon Saturday most of our area is snow.
By late afternoon most of the area is NOT snowing, but the temperature is still below freezing and stuff is falling from the sky.
By Sunday AM-- the temp is above freezing and it COULD still be raining.

Often, as you get close to these events the models catch on that it's harder to dislodge the cold air. As an example in this last storm-- sleet fell in areas where freezing rain was expected. This happened because the cold air depth was greater than modeled. (Lower levels of atmosphere)

This is NOT my prediction, but a general idea of what these events do:

Mountains 3-6 inches, ROA- LYH 2-4, Southside 1-3 inches with a good bit of ice on top.

So, we have 3-6 inches of snow left, add a few inches, add some rain and start the melting. Both Saturday and Sunday will be pretty ugly days.
