DISCUSSION
THE LATEST MODEL GUIDANCE SHOWS A PACNW LOW CONTINUING TO MOVE ALONG
THE COAST OF BC TODAY AND THEN INTO THE NW CONUS BY TOMORROW. WITH
THIS SETUP ABOVE, A COLD AND WINDY WEATHER SYSTEM CONTINUES TO
IMPACT THE CWA TODAY AS A COLD FRONT MOVES THROUGH THE REGION.
DAYTIME HIGH TEMPERATURES ARE ON TRACK TO BE AROUND 10-15 DEGREES
COOLER THAN THOSE EXPERIENCED ON THURSDAY. W NV VALLEYS WILL HAVE
HIGHS IN THE MIDDLE 70S TO LOWER 80S RANGE WHILE SIERRA COMMUNITIES
WILL BE IN THE IN THE MIDDLE 60S TO LOWER 70S RANGE. A SECOND
COLD FRONT MOVES THROUGH THE REGION ON SATURDAY WHICH WILL COOL
DOWN TEMPERATURES EVEN MORE WITH DAYTIME HIGHS GENERALLY IN THE
60S AND 70S (PORTIONS OF MINERAL COUNTY SUCH AS HAWTHORNE MAY HANG
ON TO THE LOWER 80S). PLEASE BE PREPARED FOR A CHILLY NIGHT ON
SATURDAY INTO EARLY SUNDAY WITH LOW TEMPERATURES IN 30S AND 40S
SOME SIERRA COMMUNITIES WILL DROP NEAR OR BELOW THE FREEZING MARK
AS WELL, SO TAKE TIME TO PROTECT ANY SENSITIVE OUTDOOR PLANTS AND
VEGETATION NOW.
THE PRIMARY WEATHER THREAT WITH THIS SYSTEM FOR THE REST OF TODAY
AND TOMORROW ARE THE INCREASED WINDS THAT HAVE ALREADY ARRIVED IN
THE SIERRA AND SIERRA FRONT. GENERALLY WESTERLY TO SOUTHWESTERLY
WINDS THROUGH TOMORROW EXPECT TO GUST UP TO 35-45 MPH IN LOWER
ELEVATIONS. THESE WINDS MAY DECREASE SLIGHTLY FOR A FEW HOURS
SATURDAY MORNING, BUT THEY WILL QUICKLY COME RIGHT BACK UP. RIDGE
WINDS GUST UP TO 50-60 MPH TODAY, BUT WILL CREEP HIGHER OVERNIGHT
AND REACH UP TO ALMOST 80 MPH ON SATURDAY. FIRE WEATHER CONCERNS AS
WELL AS IMPACTS TO RECREATION AND TRAVEL ARE EXPECTED WITHIN THE
REGION THROUGH TOMORROW AS A RESULT OF THESE WINDS. PLEASE REFER TO
THE RED FLAG WARNING IN W NV AS WELL AS THE LAKE WIND ADVISORY OUT
FOR AREA LAKES FOR MORE DETAILS. BLOWING DUST IS EXPECTED IN W NV
NEAR DESERT SINKS AND PLAYAS, SO USE CAUTION IF TRAVELING THROUGH
THE REGION AS REDUCED VISIBILITY MAY OCCUR.
AS FOR PRECIPITATION CHANCES FOR THE REMAINDER OF TODAY AND
TOMORROW, THERE IS A 15-25% CHANCE FOR LIGHT SHOWERS FOR THE
SIERRA CREST NEAR TAHOE, NORTHERN LASSEN AND WASHOE COUNTIES, AND
IN THE W NV BASIN AND RANGE GOING THROUGH THE AFTERNOON. DURING
THE EVENING HOURS, CHANCES FOR SHOWERS INCREASES TO 40-80% NEAR
THE OR BORDER AS THE COLD FRONT MOVES CLOSER TO THE REGION. THESE
CHANCES WILL CONTINUE INTO SATURDAY BEFORE LOWERING TO 20-60% ON
SATURDAY NIGHT WHEN THEY SPREAD SOUTH INTO THE NORTHERN TAHOE
BASIN AND THE RENO/SPARKS AREA. CHANCES FOR THUNDER WITHIN THESE
SHOWERS LOOKS TO BE AROUND 15-25% WITH HIGHER END CHANCES CLOSER
TO THE OR BORDER. NOT ANTICIPATING SEVERE WEATHER AT THIS TIME,
BUT STRONG AND ERRATIC OUTFLOW WINDS AS WELL AS BRIEF HEAVY RAIN
COULD BE POSSIBLE IF A STRONGER STORM DEVELOPS. QPF VALUES THROUGH
TOMORROW NIGHT RANGE BETWEEN A TRACE AND UP TO AROUND 0.3 INCHES
IN NE CA. SNOW LEVELS ON SATURDAY NIGHT DROP DOWN TO BETWEEN
6.5-7.5 KFT, SO HIGHER ELEVATIONS IN NE CA AND THE NORTHERN SIERRA
COULD POTENTIALLY SEE A DUSTING OF SNOW BY SUNDAY MORNING.
ON SUNDAY, PRECIPITATION CHANCES WILL DEPART OUT OF THE REGION TO
THE EAST WITH WINDS DECREASING AS THE UPPER LOW JOURNEYS EASTWARD.
COOLER DAYTIME HIGHS ARE IN THE FORECAST ON SUNDAY WITH W NV AND NE
CA VALLEYS SEEING HIGHS IN THE MIDDLE 60S TO LOWER 70S WITH SIERRA
COMMUNITIES IN THE LOWER TO MIDDLE 60S. DRY CONDITIONS ARE EXPECTED
GOING INTO THE BEGINNING OF JULY WITH AREA HIGH TEMPERATURES
RETURNING TO THE 70S AND 80S DURING THE WORK WEEK. -078
