brettjrob Posted April 17, 2013 Share Posted April 17, 2013 Right under the western/FDR cell and it looks pretty junky. Rotation is extremely broad.

Superstorm93 Posted April 17, 2013 Share Posted April 17, 2013 DISCUSSION...A QUASI-STATIONARY BOUNDARY EXTENDS FROM JUST W OF BVO TO NRN PORTIONS OF OKC METRO TO S OF CDS. RECENT RADAR IMAGERY FROM KTLX SHOWS THE BOUNDARY HAS BEGUN TO MOVE SWD OVER CENTRAL OK...POSSIBLY AS A RESULT OF OUTFLOW FROM POST-FRONTAL CONVECTION NW OF OKC. A SUPERCELL TSTM NEAR LAWTON OK WILL CONTINUE MOVG NEWD IN AN ENVIRONMENT FAVORABLE FOR LOW-LEVEL ROTATION/TORNADO DEVELOPMENT AS STRENGTHENING LOW-MID-LEVEL FLOW FURTHER ENHANCES 0-1 KM SRH VALUES THROUGH 00Z. THIS STORM WILL LIKELY REMAIN OUT AHEAD OF THE SURFACE BOUNDARY THROUGH 00Z AS IT MOVES NEAR/ALONG THE I-44 CORRIDOR. OTHER SUPERCELL TSTM DEVELOPMENT OVER FAR SWRN OK/NWRN TX IS LOCATED TO THE EAST OF THE FRONTAL BOUNDARY/DRYLINE TRIPLE POINT AND WILL ALSO HAVE THE POTENTIAL TO PRODUCE TORNADOES...LARGE HAIL AND DAMAGING WINDS IN A STRONGLY-SHEARED AND RELATIVELY LOW-LCL ENVIRONMENT. LATEST CONVECTION-ALLOWING MODEL GUIDANCE SUGGESTS THAT ADDITIONAL SUPERCELL DEVELOPMENT MAY OCCUR OVER SOUTH-CENTRAL OK DURING THE NEXT FEW HOURS...AND RECENT RADAR IMAGERY SHOWS A SLIGHT INCREASE IN CONVECTIVE ECHOES. AN EWD EXTENSION OF CURRENT WW MAY BE NEEDED IF THIS SCENARIO BEGINS TO UNFOLD. TO THE WEST OF THE SURFACE BOUNDARY...TSTMS MAY EXHIBIT MID-LEVEL ROTATION BUT WITH SURFACE OBS SHOWING SEVERAL DEGREES OF COOLING ASSOCIATED WITH FRONTAL PASSAGE...LARGE HAIL AND PERHAPS DAMAGING WINDS WILL BE THE PRIMARY THREATS.

wxmeddler Posted April 17, 2013 Share Posted April 17, 2013 The front continues to sink back south. It is now S of OKC down near the airport and moving into the NW side of Moore. EDIT: Will Rodgers Airport had the FROPA last hour at 29 past. It's now 57/51 at the Airport. Link to comment Share on other sites More sharing options...
thewxmann Posted April 17, 2013 Share Posted April 17, 2013 Cold air always wins... I think the supercells in OK have very little tornado threat with them as they continue to get undercut by the front. The real threat will be with the storms firing in NW TX between 00-03Z, although that may also be dependent on how fast the front crashes down there.

Superstorm93 Posted April 17, 2013 Share Posted April 17, 2013 The cells in SW OK have congealed into a messy cluster with embedded rotation. Not exactly sure what the downscale evolution of this will be once the best dynamics arrive, but If it can remain ahead of the boundary then I supposed it could produce at least a long term threat for damaging winds and possibly tornadoes. TX cells seem to really be taking off now: Link to comment Share on other sites More sharing options...

SquatchinNY Posted April 17, 2013 Share Posted April 17, 2013 Yeah, just saw that. Those TX cells have plenty of CAPE to work with, 2500-3500. EHI (3km) of 7, sigtor of 3-4. Link to comment Share on other sites More sharing options...

tornadotony Posted April 17, 2013 Share Posted April 17, 2013 This is actually really reminiscent of a day I brought up yesterday: 2/10/09. All the storms in OK are getting undercut, but that stuff in N TX might be dangerous, especially with SPS in the crosshairs. Link to comment Share on other sites More sharing options...
