MESOSCALE PRECIPITATION DISCUSSION 0333
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
527 PM EDT WED JUL 08 2015
 
AREAS AFFECTED...CENTRAL NV 
 
CONCERNING...HEAVY RAINFALL...FLASH FLOODING POSSIBLE 
 
VALID 082126Z - 090100Z
 
SUMMARY...DEEP CONVECTION WAS BUBBLING UP ACROSS PARTS OF CENTRAL
NEVADA IN RESPONSE TO DIURNAL DESTABILIZATION AND A HIGHLY
DIFLUENT UPPER LEVEL FLOW AHEAD OF A SHORTWAVE.  LOCALLY HEAVY
RAINFALL AND FLASH FLOODING WILL CONTINUE TO BE POSSIBLE IN THIS
REGION THROUGH EARLY EVENING. 

DISCUSSION...CONVECTION SHOULD CONTINUE TO DEVELOP DURING THE
AFTERNOON IN RESPONSE TO STEEPENING LOW LEVEL LAPSE RATES AND THE
FLOW ALOFT BEING HIGHLY DIFLUENT. LATEST BLENDED TPW SATELLITE
IMAGERY AND THE FROM THE 19Z RUN OF THE RAP WERE CONSISTENT IN
DEPICTING PW VALUES APPROACHING AN INCH...WHICH SUGGESTS THAT SOME
CELLS WILL BE ABLE TO PRODUCE RAINFALL RATES ON THE ORDER OF AN
INCH PER HOUR.

WITH CLOUD TOP TEMPERATURES CONTINUING TO COOL OVER UPSTREAM AND
CELLS BEING PULLED SLOWLY TO THE NORTH OR NORTHWEST...FEEL THAT
THE POTENTIAL EXISTS FOR SOME AREAS TO RECEIVE SEVERAL ROUNDS OF
HEAVY RAINFALL WHICH COULD LEAD TO FLASH FLOODING.
