kanc2001 Posted December 24, 2010 Share Posted December 24, 2010 Per the main forum, 18z thread, the 12z euro ensembles were west of the Op. I have not seen them so I don't know how far west but that would continue the trend. Link to comment Share on other sites More sharing options...

ams30721us Posted December 25, 2010 Share Posted December 25, 2010 Wow, I dont know bout much rain here in extreme NW GA tonight unless its Frz. Rain.

Temps have taken a freefall at the warmer airport tonight We have gone from 45 a few hours ago at the high down to 32 already! DP are still in the 20s at that!

neatlburbwthrguy Posted December 25, 2010 Share Posted December 25, 2010 Per radar, a really nice band of snow headed right towards nashville. looks to be snowing there before midnight... Link to comment Share on other sites More sharing options...
audioguy3107 Posted December 25, 2010 Share Posted December 25, 2010 For all you eastern Atlanta folks, we're down to 36 degrees already.......god how I would some good radiational cooling most of the night and have precip roll in just in time to keep temps down for Christmas.

neatlburbwthrguy Posted December 25, 2010 Share Posted December 25, 2010 Perhaps a met or someone could chime in on this but should we be looking for the radar to begin to blossom over louisiana and mississippi over the next 6 hours or so. Just trying to understand where all the moisture will be coming from that is going to fall in AL and GA tomorrow. Thank you in advance. Link to comment Share on other sites More sharing options...
DaculaWeather Posted December 25, 2010 Share Posted December 25, 2010 Per radar, a really nice band of snow headed right towards nashville. looks to be snowing there before midnight... If you look here, the METAR stations have little symbols, sometimes dots (for rain) and x's (for snow) 2 dot's or x's is light, 3 is moderate http://www.daculaweather.com/grlevel3/storm_mode_1.php Link to comment Share on other sites More sharing options...

SBUWX23 Posted December 25, 2010 Share Posted December 25, 2010 RDU down to 34, dewpoint at 18 Im not sure why temperatures tonight are important. Regardless if anyone cools a lot tonight, temperatures will rise tomorrow to near 40. But thats only initially and everything points to cooling by evening and snow even if the GFS is way off.

Just trying to understand where all the moisture will be coming from that is going to fall in AL and GA tomorrow. Thank you in advance. The rain shield in TX will continue to move east, arriving in west LA in the next 3 hrs, also convection should begin to increase off the TX coastline as the surface low moves offshore later tonight.

Cyric297 Posted December 25, 2010 Share Posted December 25, 2010 Out of curiosity, would any of the pros like to comment on the 23z RUC? the 19Z RUC was mentioned earlier as the last few frames might have looked like a phase on the 500Mb Vorticity maps, but I wasn't sure if the 23Z also showed this solution. I'm looking at http://www.nco.ncep.noaa.gov/pmb/nwprod/analysis/namer/ruc/hr4/index_500_l_loop.shtml. Link to comment Share on other sites More sharing options...

They are important for us due to projected boundary layer problems. We need to radiate this afternoon's heat away and then insulate with clouds before insolation warms our boundary layer and we end up with more rain than snow. We (Atlanta area) need clouds overhead by 12z. Link to comment Share on other sites More sharing options...

We (Atlanta area) need clouds overhead by 12z. Not really, once the clouds come overhead the temps will rise. Look at the 925mb temps, very warm in that area. Radiational cooling really won't make much of a difference for this storm, it's the dynamics and timing as well as track that you need to be looking for. 925mb temps Link to comment Share on other sites More sharing options...

I use UGA's Experiment Station Auto reporting system. It is about 3 miles se of me. http://www.griffin.uga.edu/aemn/cgi-bin/AEMN.pl?zip=30223 Dang, if we can get on down with the temps and then get the clouds with some virga early...

I'm looking at http://www.nco.ncep....00_l_loop.shtml. Yea if you notice the energy coming down the west side of the southern wave in the last couple of frames. The energy really forces it neutral and maybe negative. With a surface low in place the negative till will ramp it up...like putting a paddle in a river towards up stream, rather than down stream where the force of the water just slides off.
