AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RENO NV
220 PM PDT FRI AUG 13 2004
.SHORT TERM...
AREA REMAINS UNDER A VERY MOIST AND UNSTABLE ENVIRONMENT AS SOUTH TO
SOUTHEAST FLOW CONTINUED TO BRING TROPICAL MOISTURE NORTHWARD ON
WESTERN PERIPHERY OF UPPER HIGH. PRECIPITABLE WATER WAS RUNNING
ABOUT A THIRD OF AN INCH HIGHER THAN THIS TIME THURSDAY WITH LCL
ABOUT 3000 FEET LOWER. IN ADDITION THERE APPEARS TO BE A WEAK VORT
MAXIMA WORKING NORTHWARD VERY SLOWLY INTO THE AREA WHICH MAY COMBINE
WITH THE INCREASED INSTABILITY TO PRODUCE STRONG UPDRAFTS AND THE
POTENTIAL FOR MARGINAL SEVERE THUNDERSTORMS. THE MISSING ELEMENT IS
SHEAR AS ENVIRONMENTAL WINDS ARE VERY LIGHT. HOWEVER THE INCREASE
UPDRAFT STRENGTH...TERRAIN AND OUTFLOW MAY COMBINE TO HELP SPAWN
MULTICELL STORMS ORGANIZED SUFFICIENTLY TO PRODUCE DIME SIZED HAIL
AND WIND GUSTS 50-60 MPH. EXPECT THESE STORMS TO REMAIN QUITE
ISOLATED. MAIN CONCERN WILL BE FLASH FLOOD POTENTIAL AS STORMS WILL
AGAIN BE SLOW MOVING AND CAPABLE OF PRODUCING RAINFALL AMOUNTS UP TO
0.80 INCH PER HOUR. THIS IS JUST UP TO FLASH FLOOD GUIDANCE LEVELS
FOR MOST AREAS AND THUS EXPECT FLOODING TO BE LOCALIZED. THE MAIN
AREA TO WATCH WILL BE THE WATERFALL FIRE BURN AREA WHERE FLASH FLOOD
THRESHOLDS ARE CONSIDERABLY LOWER. SATURDAY WILL BE SIMILAR AS
THERE WILL BE LITTLE AFFECT FROM PACIFIC TROUGH. LIGHT WINDS AND
UNSTABLE CONDITIONS WILL LIKELY SET OFF ANOTHER ROUND OF STORMS WITH
PLENTY OF MOISTURE FOR STORM CELLS TO UTILIZE. THERE IS NOT LIKELY
TO BE MUCH DRYING OF THE ATMOSPHERE INTO SUNDAY AND MONDAY ALTHOUGH
HEIGHTS DO RISE AND WARMING ALOFT WILL HELP DECREASE AMOUNT OF
INSTABILITY AND THUS LIMIT AREAL COVERAGE AND INTENSITY OF ACTIVITY.
THIS FORECAST WILL CONTINUE TO SHOW A GRADUAL DEMISE OF THE DAYTIME
CONVECTION SUNDAY AND MONDAY. TEMPERATURES WILL BE NEAR OR SLIGHTLY
ABOVE NORMAL WITH GENERALLY LIGHT WINDS. HOHMANN

PRESSURE OVER REGION...AIR MASS WILL NOT MODIFY VERY MUCH THROUGH
MID-WEEK. WITH THE MOISTURE IN PLACE WILL CONTINUE WITH SLIGHT
CHANCE TSTMS. THE RIDGE STARTS TO BREAK DOWN ON FRIDAY AS AN UPPER
LOW MOVES INTO BRITISH COLUMBIA. THE TROUGH ASSOCIATED WITH THIS
SYSTEM WILL MOVE INTO NORTHERN CALIFORNIA ON FRIDAY. WITH THIS
FEATURE MOVING THROUGH WILL CONTINUE WITH SLGT CHC TSTMS INTO
