John1122 Posted November 12, 2019 Share Posted November 12, 2019 Just absolutely pouring rain right now. I always hate the hours waiting on a changeover, using up QPF. Wouldn't be shocked to see it fall apart here as shown on some modeling and see it redevelop over the eastern areas. Looks ragged downstream in the cold, without that enhancement on the front the far eastern areas look like they might get, I'm thinking maybe 1/2 inch for me.

Seems like temps are falling lower than I expected. Edit: he just told me schools are closing in Jackson. He wasn’t expecting to get anything more than a few flakes. . It's a potent from. My area is modeled to be around 23 by day break. 1 Link to comment Share on other sites More sharing options...

PowellVolz Posted November 12, 2019 Share Posted November 12, 2019 MRX now saying mods are showing an enhancement of snow in the morning for the valley and they might add Knox and a few others to the WWA. They upped totals in the valley. Seems like IMO they just wanted to wait until it seemed probable that the mods were on to what has been shown for the last 24 hours. . 3 Link to comment Share on other sites More sharing options...
TellicoWx Posted November 12, 2019 Share Posted November 12, 2019 Comparing current temps in Crossville to the 18z Euro meteogram, the front looks to be about an hour ahead of schedule. Question now is does the moisture back over MS fill in and pivot to the north as modeled. 3 Link to comment Share on other sites More sharing options...
John1122 Posted November 12, 2019 Share Posted November 12, 2019 Quote Tonight Rain before 2am, then snow. Patchy fog after 2am. Low around 24. West wind 10 to 15 mph becoming north after midnight. Winds could gust as high as 30 mph. Chance of precipitation is 100%. Total nighttime snow accumulation of 1 to 2 inches possible. This had said accumulation near 1 inch before the grid refresh. 1 Link to comment Share on other sites More sharing options...
PowellVolz Posted November 12, 2019 Share Posted November 12, 2019 MRX has also lowered my low temp from 33 to 30 during the update . 1 Link to comment Share on other sites More sharing options...
ShawnEastTN Posted November 12, 2019 Share Posted November 12, 2019 My temp has finally began falling, fell from 60 to 54 over the last 30 minutes IMBY.Sent from my SM-G965U using Tapatalk 2 Link to comment Share on other sites More sharing options...
John1122 Posted November 12, 2019 Share Posted November 12, 2019 Somerset is 34 but with rain still. Hopefully it's close to switching over. A shame to waste QPF at that temp. Link to comment Share on other sites More sharing options...
Save the itchy algae! Posted November 12, 2019 Share Posted November 12, 2019 Rain picking up in Farragut. Not much of a temp change the last few hours. Link to comment Share on other sites More sharing options...
John1122 Posted November 12, 2019 Share Posted November 12, 2019 The snow line looks like it's moving at about 25 mph. Its about 75 miles WNW of me. Link to comment Share on other sites More sharing options...
ShawnEastTN Posted November 12, 2019 Share Posted November 12, 2019 Since my temp started falling the wind has also really picked up in a big way. Raining leaves occasionally from out of the woods around my house.Sent from my SM-G965U using Tapatalk Link to comment Share on other sites More sharing options...

TellicoWx Posted November 12, 2019 Share Posted November 12, 2019 Honestly a very hard call for MRX south of 40, looking at the RAP/HRRR soundings, they support snow falling in the valley but the surface temps are between 33-35. Going to be hard to get much to stick unless we can hit the 32 mark quicker. Link to comment Share on other sites More sharing options...

If it plays out like those two models, think ridges in the valley roughly around 1000' and above will have the better chance at accumulation.

John1122 Posted November 12, 2019 Share Posted November 12, 2019 Precip has died here and upstream of here. Will see if the precip in the mid state can get here, thinking I'll be lucky to get dusting at this point. Link to comment Share on other sites More sharing options...
John1122 Posted November 12, 2019 Share Posted November 12, 2019 Down to 32 but still no precip. Just misty. See that Crossville is picking up LT snow now. That's basically upstream for me. Link to comment Share on other sites More sharing options...
John1122 Posted November 12, 2019 Share Posted November 12, 2019 Sleet/snow mix has finally started. Looks like maybe 2 hours of precip still to go for my area. Link to comment Share on other sites More sharing options...
John1122 Posted November 12, 2019 Share Posted November 12, 2019 Still a good portion of what's falling is sleet. The warm nose is apparently potent up there somewhere. Link to comment Share on other sites More sharing options...
