INSTABILITY WILL DEVELOP BY MID-DAY WITH LI'S NEAR -2 AND MUCAPE
NEAR 300 J/KG THIS WILL PRODUCE ISOLATED TO SCATTERED
THUNDERSTORMS ACROSS THE REGION WITH SOME STORMS BECOMING STRONG
DUE TO GOOD DYNAMICS WITH LEFT EXIT REGION OF JET...MAIN THREAT
WILL BE GUSTY DOWNBURST WINDS UP TO 45 MPH MAINLY ACROSS THE
EASTERN HALF OF THE CWA WHERE THE LOW LEVELS WILL BE A BIT
DRIER...HOWEVER OTHER AREAS WILL HAVE THE POTENTIAL FOR GUSTY
OUTFLOW WINDS FROM SHOWERS AND THUNDERSTORMS. ADDITIONALLY SOME
SMALL HAIL IS POSSIBLE WITH THESE STORMS. A SURFACE LOW HAS
DEVELOPED SOUTH OF TONOPAH WITH TIGHTENING PRESSURE GRADIENT WHICH
WILL PRODUCE GUSTY WINDS UP TO 35 MPH IN SOME PARTS OF THE
CWA...THIS SURFACE LOW WILL PUSH NORTHEAST INTO UTAH DURING THE
AFTERNOON HOURS. DUE TO STRONG DYNAMICS WESTERN PORTIONS OF THE
CWA COULD SEE .25" TO .50" OF RAINFALL TODAY.

AND THEN STALL BRINGING GOOD QPF TO CENTRAL NEVADA ESPECIALLY FOR
LANDER AND NYE COUNTIES WITH UP TO .50" POSSIBLE IN SOME AREAS.
ISOLATED THUNDERSTORMS WILL CONTINUE THROUGH TUESDAY NIGHT AS INSTABILITY
WILL EXIST AND STORMS WILL INCREASE IN COVERAGE DURING WEDNESDAY
AFTERNOON. THERE WILL STILL BE SOME JET SUPPORT BUT WEAKER SO
STORMS ARE NOT EXPECTED TO BE STRONG.

SOME MOISTURE LEFT HANGING AROUND...BUT GFS BUFR SOUNDINGS INDICATE
A CAP DEVELOPING BETWEEN THE 450-550 MB LEVEL. HAVE KEPT VERY LOW
END ISOLATED SHOWERS AND THUNDERSTORMS IN THE FORECAST...AND WILL
CONTINUE TO LOOK AT LATER RUNS.

FLAT RIDGING MOVES INTO NORTHERN NEVADA. DRY AND QUIET CONDITIONS
WILL PERSIST INTO THE WEEKEND.
