MESOSCALE DISCUSSION 1598
   NWS STORM PREDICTION CENTER NORMAN OK
   0358 PM CDT SAT JUL 02 2005
   
   AREAS AFFECTED...SERN WY...ERN CO...NWRN KS...AND FAR SWRN NEB
   
   CONCERNING...SEVERE THUNDERSTORM POTENTIAL 
   
   VALID 022058Z - 022300Z
   
   DRY MICROBURSTS POSSIBLE WITH HIGH BASED STORMS ACROSS THE CENTRAL
   HIGH PLAINS THROUGH EARLY THIS EVENING. ANTICIPATED
   LOCALIZED/ISOLATED NATURE OF WIND POTENTIAL WILL LIKELY PRECLUDE WW.
   
   
   HIGH-BASED CONVECTION DEVELOPING ALONG THE ERN SLOPES OF THE ROCKIES
   IN CO/WY WILL TRACK GENERALLY ESEWD AT 20KT DURING THE NEXT FEW
   HOURS. LOW-LEVEL WLY FLOW ACROSS THE HIGH PLAINS HAS RESULTED IN
   EXTREME SURFACE DEWPOINT DEPRESSIONS...WITH TEMPERATURES IN THE 90S
   AND DEWPOINTS IN THE LOW 30S. INVERTED-V THERMODYNAMIC PROFILES WILL
   SUPPORT EXTREME EVAPORATION POTENTIAL IN DOWNDRAFTS AND LOCALIZED
   DRY MICROBURSTS ACROSS SERN WY/ERN CO DURING THE NEXT SEVERAL HOURS.
   ADDITIONALLY...SURFACE TROUGH EXTENDING EWD ALONG I-70 CORRIDOR FROM
   LIC TO GLD AND NEWD TOWARD MCK IS ASSOCIATED WITH DEEP-MIXING AND
   INCREASING CUMULUS CONVECTION. ISOLATED THUNDERSTORMS ALONG THIS
   AXIS FROM FAR ERN CO TO SWRN NEB MAY ALSO BE CAPABLE OF PRODUCING A
   DRY MICROBURST OR TWO. LIMITED LOW-LEVEL CONVERGENCE AND CAPPING
   FURTHER EAST IS EXPECTED TO KEEP MOST ACTIVITY ISOLATED AND
   SHORT-LIVED. ANTICIPATED ISOLATED NATURE OF WIND POTENTIAL WILL
   LIKELY PRECLUDE WW ISSUANCE.
