Vols1982 Posted January 16, 2018 Share Posted January 16, 2018 Long time Lurker guys. I appreciate all you all do. I live in the Tri Cities area. We are at 32 degrees and partly sunny. My humidity is at 81%. I'm hoping this sun is going to juice up the air a bit. System seems to be building to the south west. Buddy of mine is getting snow in La Follette now. Hoping that's showing its progressing east north east. Again thank you all. Fingers crossed for an over performer for all of us! Link to comment Share on other sites More sharing options...

WinterWonderland Posted January 16, 2018 Share Posted January 16, 2018 Here is Robert's (WxSouth) latest thinking: Final Snow Call Map (Tuesday January 16, 2018) by wxsouth • January 16, 2018 It looks like I’m going to have to adjust down in most areas. As the RGEM, GGEM and ICON I fell for were (or going to be) simply too sharp too far west I think. At this point they looked overdone and now viewing all guidance, the European looks about right overall. Tonight as the upper wave scoops more moisture quickly through Georgia and just east of the mountains in NC and VA, there will be enhancement going on. Meaning better lift than what may occur just west of the southern Apps in western GA and central Alabama where lift sort of falls in a lull. One spot that may be surprised is middle GA or even Atanta area, maybe attaching more up 85 and across 26 northwest of Columbia since the UVVs are going to be increasing rapidly around midnight and after, so the snow map is hard to draw in every region, so I had to be broad. But the 1 to 2″ amounts may get pretty close to the area just mentioned but isn’t outlined. Surprises usually happen and the snow graphic will be right some areas, wrong some areas. By and large a weak system with minimal moisture, but the rates and duration will probably increase in central NC and central VA, possibly ending as snow to the coast. Also, rain may start the event along and near 85 from western SC Upstate to southern Piedmont NC tonight with lack of strong cold there early on.

nrgjeff Posted January 16, 2018 Share Posted January 16, 2018 Welcome new and returning posters! Feel free to start an obs thread. Jax thank you for the pic. Did that escalate quickly? Snow totals are doing better than one would expect with actual radar returns. Trend refuses to end. Kentucky and Barkley lake effect will be under the radar. Check VIS. When the surrounding area clears, look for remaining streamers. Today could be a very memorable 24 hours ending 03Z. Kansas hoops enjoyed its biggest come-from-behind road win in 20 years at Morgantown WV last night. Meaningful snow in Chattanooga is likely! No cliff diving below! Did you check the short-wave coming out of Mississippi? Satellite (esp vapor) is a strong ally. Link to comment Share on other sites More sharing options...

John1122 Posted January 16, 2018 Share Posted January 16, 2018 The HRRR is not handling the initial band of snow very well at all. It keeps drying it out too fast. Per last hour there was supposed to be no snow in northern Middle Tn right now. So now it had to adjust that and shows barely any snow next hour. It keeps missing badly on what's actually happening.
