brettjrob Posted March 2, 2014 Share Posted March 2, 2014 I think the last time the thundersleet thing happened was during the ice storms of 2007 or 2008. It happens here with surprising regularity. I think the last instance was 2011, though. It will be hard to top what happened immediately behind the cold front during the infamous 11/30/06 storm, when we had torrential thundersleet lasting for a couple hours, accumulating hail, and SVR warnings abound. However, the cells moving out of SW OK may try to rival that in spots this afternoon. Link to comment Share on other sites More sharing options...

It's getting hard to keep track after all the little events this winter. I just realized that if you count the early April ice storm, C OK has seen winter storms in 6 of the last 12 calendar months.

NwWhiteOut Posted March 2, 2014 Share Posted March 2, 2014 Switched over to a very fine light snow here now. Probly go back to sleet if more thunderstorms roll through idk Back to a mixture again of sleet/snow lol Link to comment Share on other sites More sharing options...
westhope84 Posted March 2, 2014 Share Posted March 2, 2014 All snow in midtown Tulsa. Light snow. Impressive radar returns just west, south, and north of the area. At 13 degrees, once a heavy, convective band moves through, snowfall rates are going to be amazing. Let's hope we can stay snow here for the rest of the event.

JoMo Posted March 2, 2014 Share Posted March 2, 2014 Sleeting here... Guess the warm layer is still around. I think 2-6" snow will be a good call, and most of that should come after dark around the upper low itself. Link to comment Share on other sites More sharing options...

JoMo Posted March 2, 2014 Share Posted March 2, 2014 JoMo any thoughts on Tulsa snow totals? It is sleeting like crazy right now Sent from my SM-N900V No idea. It's even still sleet up here despite the snow flurries all day, so I guess we'll have to wait until the upper low gets closer, and by that time, we may only have a few hours of snow.

JoMo Posted March 2, 2014 Share Posted March 2, 2014 Looks like there's a warm layer between 700-850 MB that still exists. It'll disappear with the approach of the system, but we may have to rely on the precip around the upper low itself to give us snow.

Wx 24/7 Posted March 2, 2014 Share Posted March 2, 2014 All of the forecast offices have changed their totals almost hourly it seems (who can blame them). I think persistence is key at this point. Link to comment Share on other sites More sharing options...
NJ_Ken Posted March 2, 2014 Share Posted March 2, 2014 FWIW, Tulsans (and those northeast of Tulsa) when those storms went through OKC, the heavier the precip, the more they were pure sleet. Each time the precip lightened up, more and more snow mixed in. Right now, we are in the back end, and we are back to getting mostly light snow again. I am sure there is a meteorological explanation for that, but I sure don't know it. Lol. Regardless, it has been one heck of an interesting 24 hours of weather here!!

JoMo Posted March 2, 2014 Share Posted March 2, 2014 Here's the HRRR depiction for the snow tonight with the upper low. It takes 4-6 hours to traverse the area. I would think there would be decent snow rates with temps hanging out in the teens and single digits? Link to comment Share on other sites More sharing options...

If I were to venture a guess, I'd say that like that 17Z sounding I posted earlier, your area has a near surface layer of air so cold that precipitation is actually beginning to re-crystalize as it falls. However, in the more convective elements, the downdrafts are probably sending the precip through the layer too fast for re-crystallization to occur well and just freezes, hence mostly sleet.

OKStorm Posted March 2, 2014 Share Posted March 2, 2014 The thunder sleet that passed thru Tulsa today was impressive at times. Some of the sleet was closer to hail in size and really stung. There was a report down south of Muskogee that sleet came down at over 1 inch in 15 minutes. Link to comment Share on other sites More sharing options...
