.SYNOPSIS...HIGH PRESSURE WILL REMAIN CENTERED OVER NORTHWEST MEXICO

MOJAVE DESERT. PERSISTENT MID LEVEL MOISTURE AND INSTABILITY WILL
LEAD TO ISOLATED SHOWERS AND THUNDERSTORMS OVER
INYO...ESMERALDA...LINCOLN AND CENTRAL NYE COUNTIES TODAY.
TEMPERATURES WILL BE A LITTLE COOLER DUE TO A WEAK DISTURBANCE
MOVING ACROSS CENTRAL NEVADA.
&&

.UPDATE...A WEAK DISTURBANCE CURRENTLY MOVING THROUGH CENTRAL
CALIFORNIA IS ALREADY KICKING OFF A FEW SHOWERS AND THUNDERSTORMS
OVER THE OWENS VALLEY AND LINCOLN COUNTY. EXPECT COVERAGE TO
INCREASE THIS AFTERNOON...ESPECIALLY EAST AND NORTH OF THE LOW
CENTER. THIS PUTS LINCOLN COUNTY IN THE HIGHEST THREAT FOR
THUNDERSTORMS TODAY. 12Z MODEL RUNS ALSO SHOW THE LOW CENTER TO BE A
LITTLE FURTHER SOUTH THAT EARLIER RUNS WHICH MAY INCREASE POP
CHANCES FOR NORTHERN SAN BERNARDINO COUNTY ALONG WITH THE SHEEP
