KEY MESSAGES
* HIGH PRESSURE OVERHEAD WILL BRING DRY CONDITIONS, ABOVE AVERAGE
AFTERNOON HIGHS, LIGHT WINDS, AND VALLEY INVERSIONS THROUGH
THIS WEEK.
* THE HIGH PRESSURE MAY WEAKEN BY THIS WEEKEND WITH PRECIPITATION
CHANCES RETURNING BY THE SECOND WEEK OF FEBRUARY, BUT
CONFIDENCE IS LOW.
DISCUSSION
HIGH PRESSURE REMAINS OVERHEAD THROUGH SATURDAY, KEEPING WESTERN NV
AND THE SIERRA DRY AND RELATIVELY WARM. HIGH TEMPERATURES WILL HOVER
AROUND 60 FOR LOWER NV VALLEYS AND AROUND 50-55 FOR SIERRA VALLEYS
THIS WEEK. WINDS WILL REMAIN LIGHT AND VARIABLE THIS WEEK, WITH AIR
STAGNATION AND VALLEY INVERSIONS NOTICEABLE IN THE MORNINGS AND
AFTERNOONS.
ENSEMBLES AND LONG RANGE DETERMINISTIC MODELS ARE SHOWING THE
POSSIBILITY OF OUR NEXT SYSTEM MOVING IN AS EARLY AS THE 6TH OR 7TH
OF FEBRUARY. A CUT-OFF LOW LOOKS TO SLIDE UP FROM SOCAL AND PASS BY
SOUTHERN NV INTO UT, GIVING MONO COUNTY A VERY LOW (10%) CHANCE OF
SHOWERS FRIDAY AND SATURDAY, THOUGH CONFIDENCE IS STILL LOW.
HOWEVER, WHERE CONFIDENCE IS HIGHER, IS A COUPLE DAYS LATER AROUND
THE 8TH OR 9TH OF FEBRUARY. MODELS ARE IN BETTER AGREEMENT ABOUT A
MODERATE COLD FRONT MOVING THROUGH SOME TIME AROUND SUNDAY OR
MONDAY. SNOW LEVELS ARE EXPECTED TO BE AROUND 6000 FT OR LESS FOR
THIS SYSTEM, SO WE'LL SEE HOW THIS PANS OUT THROUGHOUT THIS WEEK IF
WE'RE ABLE TO PICK UP MORE SNOW FOR THE SIERRA. CW3E'S GEFS IVT
PLUME DOESN'T LOOK TOO IMPRESSIVE EITHER, SHOWING MOST OF THE
MOISTURE GOING NORTH OF OUR CWA. WHILE THERE'S A STILL ROOM FOR
VARIABILITY IN THE FORECAST THAT FAR OUT, JUST KNOW THAT THERE COULD
BE ADDITIONAL SNOW FOR THE SIERRA COMING EARLY NEXT WEEK.

AVIATION
