   Areas affected...western/central Nebraska into northern Kansas

   Concerning...Severe potential...Watch possible 

   Valid 090058Z - 090300Z

   Probability of Watch Issuance...60 percent

   SUMMARY...Damaging wind potential to evolve downstream through the
   evening.

   DISCUSSION...One or more clusters of thunderstorms will move
   downstream into portions of western and central Nebraska into far
   northern Kansas this evening. Surface objective analysis suggests
   MLCIN is in place across portions of central Nebraska, with
   temperatures cooling with the diurnal cycle. THe 00z sounding from
   LBF further supports this notion with a warm nose around 850-700 mb.
   With loss of heating, it is likely MLCIN will remain, which may
   temper the downstream severe risk with northern extent. 

   A more well defined cluster coming out of eastern Colorado may
   present the more likely severe potential into the evening.
   Downstream across southern Nebraska into northern Kansas, MLCIN
   weakens with a steep gradient of MLCAPE around 1000-4000 J/kg
   extending into north-central Kansas. Additionally, strong deep layer
   shear is in place which should foster organization of a damaging MCS
   this evening.

   A new Severe Thunderstorm watch may be possible to replace portions
   of Tornado Watches 288 and 287 by 03z.
