Rain shower just changed over to light snow mix. Snow is the smallish pine needle type mixed with light rain. On and off every few minutes.

Snow will just not stick lol it is frustrating!

Thanks a bunch for the offer Nasty, but we're heading into downtown. Going to Cheeburger and the aquarium.

Mostly like a graupel sleet mix here now. See it starting to stick to eves of housetops. 33 right now.

by **John1122** 2012-12-29, 4:24 pm

A decent sleet/snow shower rolling through Hixson now.

by **Toot** 2012-12-29, 4:54 pm

Here in ETN snow should begin to pick up in intensity as an upper level disturbance moves closer to the area. Once again the radars are not picking up the snow over the plateau area. I expect light accumulations will happen in northern parts of the valley and along the plateau tonight.

Light snow in Harrison car and truck are white with temp 36 @6:25 p.m.

by **tom23** 2012-12-29, 7:03 pm

Radar is looking good as far as Central E TN goes. Outside my house the cars are getting covered and the roofs have been covered quite a while. The ground is starting to get whitened as well. Snow is coming down pretty steady. Could get a heavy dusting to a half inch from this if it keeps up. Main concern I have is icing on some of the roadways. I'd say that the favored roads (roads that tend to ice up first) are getting icey with the sun down and the already wet roads, combined with the snow falling.

by **Toot** 2012-12-30, 10:08 am

Looks like im not the only one watching the system next week

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MORRISTOWN TN
333 AM EST SUN DEC 30 2012

PRECIPITATION ENDS TUESDAY NIGHT AS FRONTAL BOUNDARY PULLS SOUTH OF THE AREA. GFS/ECMWF ARE IN DIS-AGREEMENT IN REPECT TO NEXT NORTHERN STREAM WAVE WITH ABUNDANT GULF MOISTURE. THE GFS HAS A STRONGER NORTHERN STREAM WAVE WHILE THE ECMWF IS WEAKER. BOTH MODELS SHOW ONLY MINOR PHASING OF THE NORTHERN AND SOUTHERN STREAM WAVES..SO BRUNT OF THE MOISTURE/PRECIPITATION REMAINS EAST OF THE SPINE OF THE APPALACHIANS FOR THURSDAY AND THURSDAY NIGHT. LATER SHIFTS WILL NEED TO WATCH FOR THE POTENTIAL OF GREATER PHASING OF THESE TWO SYSTEMS. IF THEY DO PHASE..THEN THE FORECAST AREA COULD SEE A DECENT SNOWFALL.

by **OakRidgeWeatherGuy** 2012-12-30, 11:47 am

Toot, for this winter storm later this week, IF it was to hit our area would it be Wednesday or Thursday?

I'm seeing it come through on Thursday myself, but that could easily change. It usually does on a lot of systems. I've seen systems where the system comes earlier than expected at 4 days out or later than expected at 4 days out. It all depends on the track and timing of the systems involved.
