MESOSCALE DISCUSSION 0927
NWS STORM PREDICTION CENTER NORMAN OK
1259 PM CDT TUE MAY 24 2011

AREAS AFFECTED...WRN AND CNTRL KS

CONCERNING...SEVERE POTENTIAL...TORNADO WATCH LIKELY

VALID 241759Z - 241930Z

A SEVERE THREAT SHOULD DEVELOP ACROSS WRN AND CNTRL KS AS STORM
INITIATE AND INCREASE IN COVERAGE THIS AFTERNOON. THE ENVIRONMENT
WILL SUPPORT A THREAT FOR LARGE HAIL AND TORNADOES. THE THREAT FOR
TORNADOES SHOULD INCREASE LATE THIS AFTERNOON AS THE LOW-LEVEL JET
STRENGTHENS. A TORNADO WATCH WILL LIKELY BECOME NECESSARY BY 19Z TO
20Z ACROSS THE REGION.

SCATTERED STRONG THUNDERSTORMS ARE CURRENTLY ONGOING IN ERN CO TO
THE NW OF A SFC LOW IN THE NRN TX PANHANDLE. THIS ACTIVITY WILL
CONTINUE TO INCREASE IN COVERAGE EXPANDING EWD ACROSS WRN AND NCNTRL
KS THIS AFTERNOON AS A SHORTWAVE TROUGH MOVES OUT INTO THE SRN AND
CNTRL HIGH PLAINS. AHEAD OF THE SHORTWAVE TROUGH...THE EXIT REGION
OF A WELL-DEVELOPED 70 TO 85 KT MID-LEVEL JET WILL EJECT NEWD ACROSS
THE CNTRL PLAINS CREATING STRONG DEEP LAYER SHEAR PROFILES AND
ENHANCING LIFT. THIS COMBINED WITH MODERATE DESTABILIZATION AND VERY
STEEP MID-LEVEL LAPSE RATES WILL BE FAVORABLE FOR THE DEVELOPMENT OF
SUPERCELLS WITH LARGE HAIL. IN ADDITION...A 35 TO 45 LOW-LEVEL JET
IN NRN OK IS FORECAST TO EXPAND NWWD INTO WCNTRL KS LATE THIS
AFTERNOON. THIS WILL CREATE A LOW-LEVEL SHEAR ENVIRONMENT
INCREASINGLY FAVORABLE FOR TORNADOES. THE MORE DOMINANT SUPERCELLS
MAY HAVE A THREAT FOR STRONG TORNADOES ESPECIALLY ACROSS CNTRL KS
WHERE MODERATE INSTABILITY IS ALREADY IN PLACE.

Seeing reports that the NWS is asking folks to stay off I-35 and I-40 in OK and S KS this afternoon/evening if possible. Obviously our weather folks are doing everything they can to not see a repeat what we have seen the past month due to tornadoes across the US.

Portastorm told me on Facebook he has never seen that before. Again, this could be really rough. Goodness gracious...

Question for anyone who can answer: On another forum, there's a poster who calls every sat view with lines of clouds in them "gravity waves" - are these gravity waves & if so, what's the significance?
