CHATTANOOGA (WRCB) - Clouds will be increasing tonight and rain, sleet and snow will move into our area between midnight and 7:00 a.m. from the west.
Snowfall will continue off and on through Christmas Day and taper off Christmas night.
The computer guidance has not changed that much since Thursday and the amounts we will receive will vary from just a dusting to 1 inch, with a few places especially in the higher elevations nearing 2 inches.
Roads should be good shape because much of the snow will melt. Most of the accumulations will be on grassy areas, parked cars, roof tops, deck and porches.
Temperatures will drop below freezing Christmas night and there could be a few more slick spots.
Sunday will be a cold blustery day, so use those Christmas gloves, caps and scarves I wish everyone a very Merry and Safe Christmas!

CHATTANOOGA (WRCB) - A storm system will head out of the Rocky Mountains and reform in the Great Plains. It is the same storm that dropped enormous amounts of rain in California earlier this week.
My thinking now is that it will sweep across the Mississippi River Valley on Friday night and then into the Tennessee Valley early Christmas Day.
It would be very surprising if we would not see any snow. But the whole event may begin as rain or as sleet mixed with some rain on Friday night, after midnight.
There is a chance for up to an inch of snow in the valleys and maybe 1-2 inches in the higher elevations.
Snow showers will likely continue off and on into Saturday night and Sunday. Temperatures on Sunday will be much colder and winds will make it feel even colder.
This sequence of events is still subject to change, but the latest guidance from the computer models is showing anywhere between a dusting to 2 inches possible.

CHATTANOOGA (WRCB) -The Christmas forecast is starting to come into focus.
We will start to see precipitation falling possibly as light rain during the overnight hours of Christmas Eve into Christmas morning.
It will change over into all snow by about 5 or 6 Christmas morning, and light snow showers will continue through the early afternoon hours.
By the late afternoon, it will reduce to light flurries that may last into Sunday.
Right now, it looks like accumulations of snow will happen Saturday with .50" to 1" in the valleys, and 1"-2" in the mountains. Some mountain locations may even see higher amounts in isolated spots.
Temps for the most part will stay above freezing throughout the day, but freezing in some of the higher elevations Saturday morning may make travel hazardous.
The low in Chattanooga Saturday will be in the low 30s with the high climbing to about 40.
CHATTANOOGA (WRCB) - We're one day closer to Christmas and just a little bit closer to a solution on the Christmas snow of 2010.
The weather charts are diverging on a solution, but I think we will likely see some accumulation starting Christmas morning.
Amounts should range from 1-2 inches with the snow tapering off after dark on Saturday night.
Temperatures should be warm enough to keep the snow melting on most roads with just an occasional slick spot developing Saturday night as temperatures drop below freezing. The precipitation could start with some rain mixed with sleet before changing to snow.
CHATTANOOGA (WRCB) Is there a chance for a white Christmas this weekend. Storm Alert meteorologist David Karnes says, "The chances for snow are increasing, but how much we get is still a question mark."
A low pressure center will move by to our south this weekend, and the exact track of that low will be the difference between a light dusting, and 1-2".
Looking at our latest locally run microcast model, it is coming in line with other model data showing about a half inch of snow accumulating through Saturday morning.
We could continue to see light flurries as late as Sunday morning, but the most significant snow looks like it will be during the overnight hours of Christmas Eve into Christmas morning (ho-ho-ho).
Also, brace for a cold Christmas Day. Temps will be in the low to mid 30s through most of the day Saturday.
The Channel 3 Storm Alert team will continue to monitor this developing system to let you know if indeed we will have a white Christmas.

CHATTANOOGA (WRCB) - New weather charts are coming into the Storm Alert all day long. And interest grows as we get closer to Christmas Day.
There is still a good chance for at least some flurries on Saturday. One of the computer models is a bit more aggressive with the system as it moves west.
The storm is still along the west coast so it has some time before it makes up its mind.
Snow lovers should hope for a southern track that would take it near the Gulf coast. If that happens we could see some significant accumulations.
Most of the computer models are taking the storm right over North Georgia. That would give us just a few dusting to a few flurries.
The table is set and the main ingredients are still in the kitchen.
So now we wait.
CHATTANOOGA (WRCB) – You may be "dreaming of a white Christmas", but could it really happen in the Chattanooga area?
It just might.
"A winter weather system will develop this week in the Midwest and by Christmas Eve it will get much closer to the Tennessee Valley," says Chief Meteorologist Paul Barys.
Paul has been reviewing his forecasting models for snow this weekend.
"Some of the weather charts are showing a good chance for some light snow falling on Christmas Day and night with temperatures falling though the day."
While the certainty of a White Christmas is solid yet, Paul says you can expect a cold Christmas for sure.
"As of now it looks good for at least some flurries and gusty winds. But many things can change before this weekend. So if you get some Christmas mittens and caps they may come in handy!"
