DISCUSSION
CLEARING SKIES OVERNIGHT BROUGHT CHILLY TEMPERATURES INTO THE 20S
TO LOWER 30S ACROSS MOST LOWER ELEVATIONS, WITH COLDER SIERRA
VALLEYS DIPPING INTO THE TEENS THIS MORNING. SIMILAR NEAR OR BELOW
FREEZING LOWS ARE EXPECTED AGAIN TONIGHT.
AS THE UPPER LOW THAT BROUGHT THIS RECENT COOL WEATHER MOVES FROM
THE GREAT BASIN TO THE ROCKIES, HIGH PRESSURE OFF THE WEST COAST
WILL EXTEND INLAND ACROSS NORTHERN CA-NV LATER THIS WEEK AND HOLD
IN PLACE THROUGH MUCH OF THE WEEKEND, KEEPING THE REGION DRY. THIS
WILL ALLOW FOR A WARMUP FROM MID-LATE WEEK, WITH HIGHS PEAKING IN
THE MID-UPPER 70S FOR LOWER ELEVATIONS AND NEAR 70 FOR SIERRA
COMMUNITIES FROM FRIDAY THROUGH THE WEEKEND. LINGERING NE-E WINDS
OVER THE SIERRA RIDGES AND NORTH WINDS IN WEST CENTRAL NV WILL
DIMINISH OVERNIGHT AND WEDNESDAY, BUT AN EAST TO SOUTHEAST WIND
GRADIENT RETURNS THURSDAY THROUGH FRIDAY AS AN UPPER LOW
REDEVELOPS OVER SOUTHERN CA. THIS COULD BRING AFTERNOON GUSTS OF
20-25 MPH THURSDAY-FRIDAY, WITH SIERRA RIDGE TOP GUSTS OF 40+ MPH.
LIGHTER WINDS RETURN FOR THE START OF THE WEEKEND, WITH ZEPHYR-
TYPE SOUTHWEST-WEST BREEZES ARRIVING BY SUNDAY.
FOR EARLY NEXT WEEK, ENSEMBLE/BLENDED GUIDANCE IS IN GOOD
AGREEMENT FOR A STORM ARRIVING FROM THE NORTHEAST PACIFIC. WHILE
SOME SCENARIOS BRING SHOWER CHANCES AS SOON AS LATE MONDAY
AFTERNOON, THE OVERALL CONSENSUS FAVORS INCREASING WINDS MONDAY,
WITH BEST CHANCES FOR SHOWERS (30-50%) AND SHARPLY COLDER
CONDITIONS FROM LATE MONDAY NIGHT THROUGH TUESDAY NIGHT. HIGHS ON
TUESDAY ONLY LOOK TO RANGE FROM THE UPPER 40S-MID 50S AND ALTHOUGH
PRELIMINARY SNOW LEVELS ARE RANGING FROM 6500-7000 FEET IN THE
SIERRA, LIGHT SNOW ACCUMULATIONS DOWN TO LAKE LEVEL CAN'T BE RULED
OUT, WITH POTENTIAL RAIN-SNOW MIX INTO FOOTHILLS OF FAR WESTERN
NV IF THE STORM KEEPS A TRACK OVER THE SIERRA/FAR WESTERN NV. MJD
