THROUGH TUESDAY.
WINDY CONDITIONS WERE REPORTED ACROSS THE REGION YESTERDAY WITH
WIDESPREAD GUSTS OF 35-50 MPH. DOWNSLOPE WINDS ARE STILL ONGOING IN
THE SOUTHERN OWENS VALLEY THANKS TO SUBSIDENCE BEHIND THE SHORTWAVE.
WITH THE PROSPECT OF THIS OCCURRING FARTHER EAST AS WELL, DECIDED TO
EXTEND THE WIND ADVISORIES UNTIL 5AM. LIGHTER, BUT STILL BREEZY,
WINDS ARE ANTICIPATED LATER TODAY WITH PEAK GUSTS GENERALLY 20-35
MPH. THE EXCEPTION IS WESTERN SAN BERNARDINO COUNTY WHERE WESTERLY
WINDS REMAIN 40-50 MPH. ANOTHER SYSTEM MOVES IN ON THURSDAY,
REINVIGORATING SOUTHWESTERLY GUSTS BEFORE A COLD FRONT TURNS WINDS
NORTHERLY THURSDAY NIGHT INTO FRIDAY. WILL HAVE TO MONITOR DOWNSLOPE
POTENTIAL IN THE LEE OF THE SIERRA AND SPRING MOUNTAINS AGAIN
WEDNESDAY EVENING, AS LATEST GUIDANCE SUGGESTS 30-50% CHANCES OF 40+
MPH. AS POST-FRONTAL WINDS MOVE THROUGH, THE AREAS AT GREATEST RISK
OF IMPACTFUL WINDS ARE THE SOUTHERN GREAT BASIN AND THE LOWER
COLORADO RIVER VALLEY. IN THE LATTER, WINDS WILL PEAK ON FRIDAY WITH
GUSTS 40-50 MPH LIKELY (80%). GUSTY NORTH WINDS LINGER IN THE LOWER
COLORADO RIVER VALLEY INTO THE WEEKEND WHILE BREEZES LIGHTEN ACROSS
THE REST OF THE AREA.
LATEST RADAR AND SATELLITE IMAGERY SHOWS PRECIPITATION FOCUSED IN
THE SOUTHERN GREAT BASIN AND AREAS SOUTHEAST OF I-15. THE SPRING
MOUNTAINS WERE ABLE TO SQUEEZE OUT A LITTLE MORE MOISTURE THAN
ORIGINALLY ANTICIPATED, WITH SOME GAUGES IN KYLE/LEE CANYONS
RECORDING OVER 1" OF LIQUID. SNOTEL DATA AND WEBCAMS SUGGEST 1-2" OF
SNOW HAVE FALLEN ABOVE 8000 FEET. BY DAYBREAK, THE ONLY
PRECIPITATION LEFT IN OUR AREA SHOULD BE ACROSS LINCOLN, NORTHERN
MOHAVE, AND MAYBE NORTHEASTERN CLARK COUNTIES. ONCE THIS ACTIVITY
EXITS BY LUNCHTIME, LARGELY DRY CONDITIONS ARE EXPECTED TO SETTLE IN
FOR THE NEXT SEVERAL DAYS. OUR FAR NORTHEASTERN LOCATIONS SEE A
RETURN OF 20-30% POPS ON THURSDAY AS ANOTHER SYSTEM MOVES THROUGH,
BUT BEYOND THAT, PRECIPITATION CHANCES REMAIN BELOW 10% THROUGH
TUESDAY.
TEMPERATURES GRADUALLY COOL OVER THE NEXT 3 DAYS BUT REMAIN FAIRLY
CLOSE TO SEASONABLE VALUES. FRIDAY, THE COOLEST DAY, FEATURES
FORECAST HIGHS RANGING FROM THE UPPER 60S TO LOW 80S ACROSS MOST OF
THE AREA. A GOOD CHUNK OF THE SOUTHERN GREAT BASIN HAS AT LEAST A
50% CHANCE OF FALLING TO/BELOW FREEZING FRIDAY MORNING. TEMPERATURES
QUICKLY WARM OVER THE WEEKEND, WITH SUNDAY'S FORECAST ~10 DEGREES
WARMER THAN FRIDAY'S. THE RATE OF WARMING SLOWS NEXT WEEK BUT
TEMPERATURES ARE EXPECTED TO REMAIN SOME 10+ DEGREES ABOVE NORMAL.
