It really a wait watch and see event for the most part now. Expand My last HUM image says almost 2 hrs old...trying to figure out if that's what cut a little off the HRRR accumulation earlier.

Though for me its not completely dry its back down to flurries. Though Hytop down you can't fully see it. Though BNA radar has what looks like light bands on the edge of the plateau, but because that is so far away from the BNA radar its likely heavier than it looks.

zippity Posted January 16, 2018 Share Posted January 16, 2018 Light snow in Huntsville. Definite dry slot. Link to comment Share on other sites More sharing options...
ShawnEastTN Posted January 16, 2018 Share Posted January 16, 2018 Actually that "Light looking" band on the plateau near the edge of the valley must be heavy just too far from active radar. Oak Ridge TAF site reporing heavy snow at the moment, and that band which looks broken due to lack of radar is now hitting the edge of Anderson Co. Will not be able to trust returns dbz, or the lack of returns. Link to comment Share on other sites More sharing options...

MRX site is notoriously bad for southern valley. Don't believe there is much of a dry slot happening. Link to comment Share on other sites More sharing options...

John1122 Posted January 16, 2018 Share Posted January 16, 2018 21 degrees with about 1 inch so far. Not had heavy snow yet, but it's not stopped snowing either, even when the radar showed nothing. I'm probably going to end with 1.5-2 inches if the second band toward Nashville can get here without dying out. Link to comment Share on other sites More sharing options...

ShawnEastTN Posted January 16, 2018 Share Posted January 16, 2018 What sucks is as that band leaves BNA its going to look lighter and ligher on BNA radar and no Hytop in between to get accurate returns. Link to comment Share on other sites More sharing options...
