brettjrob Posted March 2, 2014 Share Posted March 2, 2014 All hell breaking loose this evening across C OK as drizzle falls into surface temps around 15-20 F. Reports of an ungodly number of accidents, including injuries and at least one fatality so far. After we cover up the thin ice rink with IP/SN tomorrow, I can see the roads being positively undriveable until Monday afternoon at the earliest.

JoMo Posted March 2, 2014 Share Posted March 2, 2014 Lightning east of Monett. Thundershowers (sleet or freezing rain) developing down in southern MO in the 23 degree air. The bad thing about the HRRR running every hour is that once it finishes up, there's another hour of data to look at, so you can never get any rest, heh.

After we cover up the thin ice rink with IP/SN tomorrow, I can see the roads being positively undriveable until Monday afternoon at the earliest. It was amusing listening to Norman Fire on the scanner. All was quiet until about 11 PM and all hell broke loose at once on I-35 between Main and Robinson. I went over there and was amazed at the ice accumulation. It looked like they had quite a burst of freezing rain. The southeast side of town on the other hand is fairly dry in comparison.

NJ_Ken Posted March 2, 2014 Share Posted March 2, 2014 It has been snowing lightly here on the north side of OKC for several hours. Temperature is 13 F. The snow may have been a savior because earlier this morning the freezing rain/drizzle falling with temps in the teens was causing absolute chaos on the roads. There were numerous reports of accidents and, unlike the typical fender benders, many of these had injuries (and sadly, I think there have been at least two fatalities). Oddly enough, all of this mess has occurred with the radar barely hinting at anything falling. I can't even imagine what it will be like if we get into enough precip for it to actually appear on radar returns. Link to comment Share on other sites More sharing options...
OUGrad05 Posted March 2, 2014 Share Posted March 2, 2014 12 degrees, moderate snow here at my house this morning. Looks like we've had very little sleet to speak of and just a dusting of snow. I'll try to grab a pic. Link to comment Share on other sites More sharing options...

Wx 24/7 Posted March 2, 2014 Share Posted March 2, 2014 Yeah, other than the awesome thundersleet for a few minutes this morning... I have been underimpressed with this storm so far.

wildweatherman179 Posted March 2, 2014 Share Posted March 2, 2014 Gotta love waking up to lightning and sleet! Impressive cloud to ground lightning here in Adair County, OK. Not a headline you hear every day. 17 degrees with thunderstorms. Haha. Saw the heaviest 5 minutes of sleet I've ever seen as well. It was crazy.

Yep first time for me for thunder sleet and lightning, its actually pretty cool and insane all at once. I haven't been impressed at all with this storm so far but the thunderstorms from it with the sleet is cool. Had a few overnight bouts here and there of sleet but no freezing rain as of yet thank goodness! Probly an off and on thing all day, tulsa sounds like they are just completely lost lol. I can imagine this has got to be a nightmare to forecast though. Now the forecast says sleet over to snow this morning haha 1-3", definately not warning criteria in my books but eh the thundersleet is cool Link to comment Share on other sites More sharing options...
arizonasooner Posted March 2, 2014 Share Posted March 2, 2014 Interesting here in TUL. Just a little light snow for most of the morning. But now, sleet has been added to the mix. Still just light precip - nothing heavy at all... Link to comment Share on other sites More sharing options...
The Waterboy Posted March 2, 2014 Share Posted March 2, 2014 Moderate sleet here in Rogers with rumbles of thunder off in the distance. I tried to get it on video but it was too faint to hear. Link to comment Share on other sites More sharing options...
LocoAko Posted March 2, 2014 Share Posted March 2, 2014 Crazy sounding! Even crazier is that it is snowing during that sounding. The roads were awful last night as the freezing drizzle was (IMO) much heavier than I'd anticipated and earlier on. Now we are getting snow generated in the boundary layer with sleeting thunderstorms riding aloft the cold air all at 13F. This is pretty wild.

NJ_Ken Posted March 2, 2014 Share Posted March 2, 2014 Thunder sleet looks to be inbound to the OKC metro and should be starting as I type on the south side of town. Also, the radar is blossoming to our southwest all the way to the Red River so once this heavier stuff starts up, it might be with us for a while. This whole mass of... well, whatever it is... looks to roll right on up I44 so Tulsa and Joplin, look alive. You might be next. EDIT: I haven't heard any thunder yet, but the precip rates have picked up substantially. We went from light snow to moderate sleet-snow mix in seconds! Loving it!!!!
