DISCUSSION
THROUGH NEXT WEEKEND.
THIS AFTERNOON SATELLITE IMAGERY DEPICTS UNUSUALLY MOIST CONDITIONS
ACROSS THE MOJAVE DESERT AND SOUTHERN GREAT BASIN WITH CONSIDERABLE
LOW LEVEL MOISTURE LEADING TO PERSISTENT POCKETS OF LOW STRATUS AND
FOG. THERE HAS BEEN CLEARING ACROSS MUCH OF SOUTHERN NEVADA AND
NORTHWEST ARIZONA, THOUGH SOME MID ELEVATION SLOPES REMAIN BLANKED
WITHIN THE CLOUD LAYER, WHILE THE STRATUS DECK IS MORE PERSISTENT
ACROSS INYO AND SAN BERNARDINO COUNTIES. OVERALL, THE EXPECTATION IS
FOR CONTINUED IMPROVEMENT THROUGH THE EVENING THOUGH WE MAY NOT
COMPLETELY SHAKE THE STRATUS ACROSS THESE WESTERN ZONES. WITH
NIGHTFALL APPROACHING AND LOW LEVEL MOISTURE NOT GOING ANYWHERE, WE
MAY SEE SOME REDEVELOPMENT OVERNIGHT, BUT NOT CURRENTLY EXPECTING
COVERAGE TO BE AS WIDESPREAD AS THIS MORNING.
MEANWHILE, ATTENTION TURNS TO THE NEXT WEATHER SYSTEM APPROACHING
THE AREA THAT IS CURRENTLY PUSHING ASHORE ALONG THE WEST COAST.
THIS PRECIPITATION BAND WILL REACH THE SIERRA BY SATURDAY MORNING,
WITH LIGHT PRECIPITATION SPREADING EAST ACROSS THE SOUTHERN GREAT
BASIN THROUGH THE DAY SATURDAY. SNOW LEVELS WILL BE ON THE
INCREASE WITH THIS WAVE THANKS TO A DEEP SUBTROPICAL FETCH
ASSOCIATED WITH MOISTURE PLUME, HOWEVER, ELEVATIONS ABOVE 8000
FEET SHOULD REMAIN PREDOMINANTLY SNOW. THIS INITIAL ROUND OF
PRECIPITATION WILL BE FOLLOWED BY A SECOND COLDER WAVE ON SUNDAY
INTO SUNDAY NIGHT WITH SNOW LEVELS FALLING TO NEAR 6000 FEET IN
THE SIERRA. THIS WILL RESULT IN CONSIDERABLE SNOW TOTALS IN THE
SIERRA THROUGH MONDAY MORNING AND HAVE GONE AHEAD AND ISSUED A
WINTER STORM WARNING FOR SATURDAY THROUGH MONDAY MORNING. OUTSIDE
OF THE SIERRA, WINTER IMPACTS ARE EXPECTED TO BE LIMITED THANKS TO
CONTINUED HIGH SNOW LEVELS AND GENERALLY LIGHT PRECIPITATION
EXPECTATIONS.
THE WEATHER PATTERN WILL REMAIN ACTIVE INTO NEXT WEEK WITH
ADDITIONAL DISTURBANCES EXPECTED WITHIN A PATTERN THAT STARTS
FAIRLY ZONAL AND TRENDS MORE NORTHWESTERLY BY THE WEEKS END. THIS
SHOULD MARK A TREND TOWARDS SOMEWHAT COOLER STORM SYSTEMS BY THE
WEEKS END WITH LOWER SNOW LEVELS, THOUGH OVERALL PRECIPITATION
EXPECTATIONS REMAIN FAIRLY LIGHT.
