   Areas affected...NE Colorado SW NE and NW KS

   Concerning...Severe potential...Tornado Watch likely 

   Valid 232235Z - 232330Z

   Probability of Watch Issuance...95 percent

   SUMMARY...Thunderstorm are developing off the dryline in NE CO and
   NW KS. A few tornadoes will be possible with supercells through this
   evening. A tornado watch will be issued soon.

   DISCUSSION...A meso low over northeastern Colorado has backed
   low-level winds over the last several hours. Moist upslope flow is
   helping to initiate thunderstorms along the dryline west of
   Goodland. Favorable vertical shear for supercells and tornadoes will
   likely develop this evening along a warm front/wind shift
   necessitating a tornado watch soon.
