Superstorm93 Posted May 31, 2013 Share Posted May 31, 2013 Greenfield is already rotating and hasn't even become firmly established yet. Once this moves right it will hold a violent tornado potential. Link to comment Share on other sites More sharing options...
Derecho! Posted May 31, 2013 Share Posted May 31, 2013 That would be my good friend James Menzies. I actually love English accents, don't get me wrong (preferably, women, of course) it just sounds a bit odd tossed in with Val Castor, etc. Link to comment Share on other sites More sharing options...

SmokeEater Posted May 31, 2013 Share Posted May 31, 2013 MESOSCALE DISCUSSION 0908 NWS STORM PREDICTION CENTER NORMAN OK 0458 PM CDT FRI MAY 31 2013 AREAS AFFECTED...WCNTRL THROUGH CNTRL AND NERN OK CONCERNING...TORNADO WATCH 262... VALID 312158Z - 312330Z THE SEVERE WEATHER THREAT FOR TORNADO WATCH 262 CONTINUES. SUMMARY...STORMS WILL UNDERGO A RAPID INCREASE IN ORGANIZATION AND INTENSITY OVER WCNTRL AND SWRN OK. THE STORMS ARE EXPECTED TO MATURE INTO SUPERCELLS AND BECOME CAPABLE OF PRODUCING VERY LARGE HAIL AND STRONG TORNADOES AS THEY MOVE EWD AND ENEWD TOWARD CNTRL OK THIS EVENING. DISCUSSION...EARLY THIS EVENING A COLD FRONT EXTENDS FROM ERN KS SWWD THROUGH NWRN OK THEN WWD INTO THE NRN TX PANHANDLE. A DRYLINE EXTENDS FROM WRN TX NWD INTO WRN OK WHERE IT INTERSECTS THE DRYLINE. TRENDS IN SATELLITE IMAGERY SHOW CUMULUS CONGESTUS INCREASING WITHIN THE MORE DEEPLY MIXED REGIME NEAR THE DRYLINE ACROSS SWRN OK AND THE FIRST STORMS ARE INITIATING ALONG THE DRYLINE/FRONT INTERSECTION NEAR WATONGA. THE ATMOSPHERE DOWNSTREAM IS VERY UNSTABLE WITH 4000+ J/KG MLCAPE WITH DEWPOINTS IN THE LOW 70S AND VERY STEEP LAPSE RATES ALONG WITH EFFECTIVE SHEAR IS AROUND 50 KT. LOW LEVEL HODOGRAPHS ARE NOT PARTICULARLY LARGE...BUT WINDS NEAR THE SFC ARE BACKED TO SSELY ACROSS CNTRL-WCNTRL OK...AND HODOGRAPHS WILL GRADUALLY INCREASE IN SIZE AS THE LLJ STRENGTHENS. THIS ENVIRONMENT WILL SUPPORT EXPLOSIVE THUNDERSTORM DEVELOPMENT WITH STORMS RAPIDLY ORGANIZING INTO SUPERCELLS CAPABLE OF PRODUCING VERY LARGE HAIL AND STRONG TORNADOES AS THEY MOVE ENEWD THROUGH THE VERY MOIST AND UNSTABLE WARM SECTOR NEXT FEW HOURS. ..DIAL.. 05/31/2013 Link to comment Share on other sites More sharing options...

Ground Scouring Posted May 31, 2013 Share Posted May 31, 2013 Wow Those gravity waves near OKC could provide the spark for any dominant supercell to become a major producer within striking distance of OKC...of course, the small hodographs could lead to storm mergers.

Thrasher Fan Posted May 31, 2013 Share Posted May 31, 2013 The storm is sucking dirt off the ground. That's incredible. Link to comment Share on other sites More sharing options...
Ian Posted May 31, 2013 Share Posted May 31, 2013 Those cells may do fine but they sure congealed into a mass fast Link to comment Share on other sites More sharing options...
Amped Posted May 31, 2013 Share Posted May 31, 2013 On the Frederick radar you can see a low level winds backing. Lots of potential if these cells can stay discrete. Link to comment Share on other sites More sharing options...

tornadotony Posted May 31, 2013 Author Share Posted May 31, 2013 Those cells may do fine but they sure congealed into a mass fast You often get several incipient cells merging into larger supercells in these events. We'll see how these evolve. Link to comment Share on other sites More sharing options...
cstrunk Posted May 31, 2013 Share Posted May 31, 2013 Storms are not very isolated right now which is a good thing for the time being. Updrafts that can keep clean inflow will be the ones that should produce. Link to comment Share on other sites More sharing options...
cyclone77 Posted May 31, 2013 Share Posted May 31, 2013 The southern cell west of El Reno should suck in that smaller cell just to the south and then have a nice clean inflow in the next half hour. Unfortunately it's probably gonna start tracking more easterly and impact the north side of the OKC metro. Link to comment Share on other sites More sharing options...

WxKevinM Posted May 31, 2013 Share Posted May 31, 2013 definitely looks to congeal into larger cells... lets hope they keep northeast. Link to comment Share on other sites More sharing options...
Wmsptwx Posted May 31, 2013 Share Posted May 31, 2013 Good news that they are congealing...if we can keep them north of the OKC metro double bonus. Link to comment Share on other sites More sharing options...
Superstorm93 Posted May 31, 2013 Share Posted May 31, 2013 These could congeal into massive supercells similar to the El Reno supercell back in 2011 Link to comment Share on other sites More sharing options...
Ground Scouring Posted May 31, 2013 Share Posted May 31, 2013 Unfortunately, the Hinton cell may become a large right-mover into downtown OKC. Radar shows increasing rotation and inflow as well as a growth in the circulation size / rain-free area. Link to comment Share on other sites More sharing options...

SmokeEater Posted May 31, 2013 Share Posted May 31, 2013 Good news that they are congealing...if we can keep them north of the OKC metro double bonus. The southernmost cell is turning into one big supercell, this is the last thing you want them to do. And it's starting to turn due east at the Metro.
