&&
.SHORT TERM...SATELLITE IMAGERY SHOWED THE UPPER LOW STRADDLING THE
CENTRAL CALIFORNIA COAST AT 23Z AND MAKING STEADY PROGRESS INLAND.
THE LIGHTNING DETECTION NETWORK SHOWED THUNDERSTORMS ALONG THE COLD
FRONT FROM CENTRAL CALIFORNIA UP THROUGH NORTHERN CALIFORNIA. THE
FIRST THING TO NOTE WAS THE DEEPER MOISTURE PLUME IN THE SOUTHERN
SIERRA SHOULD PUSH TO THE EAST OF THE REGION BY 03Z FOLLOWED BY
LIMITED MOISTURE BUT MORE INSTABILITY SHOWERS DURING THE EVENING.
DECIDED TO DOWNGRADE THE WINTER STORM WARNING TO A SNOW ADVISORY FOR
THE EAST SLOPES AND HAVE IT END AT MIDNIGHT AS THE TROUGH AXIS
PASSES THROUGH. CLOUDS COULD BE SEEN FILLING IN ACROSS SOUTHWEST
NEVADA AND THIS WILL CONTINUE TO SPREAD EASTWARD AS BROAD ASCENT
PRECEDING THE SYSTEM INFLUENCES THE ENTIRE REGION THIS EVENING AND
OVERNIGHT. BOTH THE NAM AND GFS INDICATE A GOOD COUPLING OF MOISTURE
AND BROAD ASCENT SPREADING ACROSS SOUTHEAST CALIFORNIA INTO SOUTHERN
NEVADA BY 06Z FOLLOWED BY A DRY SLOT BETWEEN 06Z AND 12Z BEFORE THE
COLDER AIR ALOFT SPREADS IN ALONG WITH SCATTERED INSTABILITY
SHOWERS. WILL ISSUE A FLASH FLOOD WATCH FOR THE MORONGO BASIN AREA
OF CALIFORNIA DUE TO CONCERNS OF LOCALIZED MODERATE RAINFALL
IMPACTING THE BURN AREA OVER THE MOUNTAINS NEAR YUCCA VALLEY
OVERNIGHT. WILL LEAVE SNOW ADVISORIES IN EFFECT FOR SOUTH CENTRAL
NEVADA AND THE SPRING MOUNTAINS/SHEEP RANGE. THE BEST POTENTIAL FOR
BANDED HEAVY SNOWFALL STILL APPEARS TO BE LINCOLN COUNTY LATE
TONIGHT AND EARLY FRIDAY. WILL HAVE TO WATCH CLOSELY FOR POTENTIAL
LOCALIZED WARNING LEVEL AMOUNTS ASSOCIATED WITH THIS BANDING.
THE CENTER OF THE SYSTEM IS FORECAST TO BE ALONG THE NEVADA/UTAH
BORDER BY 18Z FRIDAY AND SHOWERS WILL GRADUALLY TAPER OFF AND SHIFT
EAST FRIDAY AFTERNOON AND EVENING. A SHORTWAVE RIDGE THEN QUICKLY
MOVES IN BEHIND THE SYSTEM SATURDAY FOR DRY WEATHER AND A MODERATE
REBOUND IN TEMPERATURES.
.LONG TERM...A SHORTWAVE IS FORECAST TO MOVE ACROSS NORTHERN NEVADA
SUNDAY WITH THE MAIN IMPACT FROM THE SYSTEM STAYING WELL TO THE
NORTH. FOR OUR AREA...IT WILL PRODUCE ADDITIONAL CLOUD COVER OVER
THE REGION AND BRING A SLIGHT CHANCE OF SHOWERS TO THE NORTHERN
ZONES. UNSETTLED WEATHER CONTINUES MONDAY AS A MOIST WESTERLY FLOW
BRINGS MID AND HIGH LEVEL CLOUDS ACROSS MUCH OF THE CENTRAL AND
NORTHERN AREAS OF THE CWA. THIS IS FOLLOWED BY ANOTHER STORM SYSTEM
MOVING ACROSS THE AREA TUESDAY BRINGING ANOTHER SHOT OF PRECIP TO
THE REGION. THIS ONE DOES NOT APPEAR TO HAVE A LOT OF MOISTURE WITH
IT AND ONLY SCATTERED LIGHT SHOWERS ARE INDICATED AT THIS TIME.
MODELS DIFFER SOMEWHAT ON THE OUTLOOK FOR THE END OF THE WEEK BUT
BASICALLY INDICATE DRY NORTHWESTERLY FLOW OVER THE REGION WITH
PLENTY OF HIGH LEVEL MOISTURE MOVING THROUGH. TEMPS TO REMAIN AT OR
BELOW NORMAL LEVELS THROUGH AT LEAST MID WEEK.
