   AREAS AFFECTED...KS....NE

   CONCERNING...TORNADO WATCH 361...

   VALID 272306Z - 280030Z

   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 361 CONTINUES.

   SUMMARY...NUMEROUS SEVERE STORMS ARE DEVELOPING ENEWD INTO WESTERN
   AND NRN PORTIONS OF TORNADO WATCH 361. EXPECT TORNADO...LARGE HAIL
   AND HIGH WIND POTENTIAL TO PERSIST...ESPECIALLY ACROSS NRN PORTIONS
   OF THE WATCH...FROM NWRN KS INTO SWRN AND S-CNTRL NEB OVER THE NEXT
   1-2 HOURS.

   DISCUSSION...A VOLATILE AIRMASS CHARACTERIZED BY AREAS OF MLCAPE TO
   4000 J/KG EXISTS TO THE EAST OF ONGOING STORMS...STRONG COLD POOL
   AND SFC LOW/DRYLINE NOW MOVING FROM ERN CO INTO WRN KS. IN ADDITION
   TO STORM-SCALE FORCING ON THE ADVANCING COLD POOL...AND MIXING SOUTH
   ALONG THE DRYLINE...MODERATE TO STRONG FORCING FOR ASCENT ASSOCIATED
   WITH THE PASSAGE OF MID-LEVEL SHORT WAVE TROUGH WILL CONTINUE TO
   DRIVE SEVERE TSTMS ACROSS THE WATCH AREA THIS EVENING. ACTIVITY HAS
   BEEN ORGANIZING INTO BOWING LINE SEGMENTS FROM NWRN INTO SWRN NEB
   WHERE BACKED LOW LEVEL FLOW WAS CONTRIBUTING TO A LOW LEVEL MAXIMUM
   IN STORM-RELATIVE FLOW AND EFFECTIVE SRH ON THE ORDER OF 200 M2/S2.
   DAMAGING WINDS WILL LIKELY ACCOMPANY THE WELL-FORMED BOWING SEGMENTS
   WHILE TORNADO POTENTIAL MAY BE GREATER WITH BREAKS IN LINE SEGMENTS
   AND POSSIBLY EVOLVING BOOK-END VORTICES. THIS POTENTIAL WILL MOST
   LIKELY SPREAD ACROSS NRN AREAS OF THE WATCH OVER THE NEXT 1-2 HOURS
   WHILE LOCATIONS FARTHER SOUTH CONTINUE TO HAVE A CHANCE FOR MORE
   ISOLATED STORMS INITIATING NEAR THE DRYLINE.
