DISCUSSION
A COLD START TODAY AS THE BACKDOOR COLD FRONT GAVE A GLANCING BLOW
ALONG THE SIERRA FRONT. THE FRIGID AIRMASS HAS IT'S SIGHTS SET ON
THE EAST COAST, SO IT WILL BE ON IT'S WAY OUT OF HERE AS OF THIS
AFTERNOON. HIGHS TODAY WILL REACH UPPER 40S ACROSS WESTERN NEVADA
VALLEYS WHILE SOME SIERRA COMMUNITIES WILL REACH THE LOW TO MID 40S.
SO, AS WE RESUME A GRADUAL TREND TO A WARMER HIGH PRESSURE REGIME
ONCE AGAIN, AND THE WINDS RELAX THIS MORNING, WE WILL START TO
SEE THE INVERSIONS BUILD INTO VALLEYS ONCE AGAIN.
THIS RIDGING PATTERN WILL COME WITH SOME CAVEATS IN THE FORM OF
SHORTWAVES THAT WILL OCCASIONALLY BREAK THE MONOTONY OF THE PATTERN.
THIS WEEK, A WEAK SHORTWAVE WILL BRING A TINY UPTICK IN WINDS FOR
TUESDAY, AND BY TINY WE MEAN GUSTS ONLY TO 30 MPH ON THE RIDGES. THE
WAVE WILL BE BARELY NOTICEABLE EXCEPT FOR SOME LIGHT SNOW SHOWERS
ALONG THE SIERRA CREST FOR WEDNESDAY AND CLOUDY SKIES ACROSS THE
REGION. ONCE THAT SHORTWAVE FEATURE MOVES OUT OF THE AREA, WE RETURN
TO OUR REGULARLY SCHEDULED FORECAST OF SLOW, GRADUAL WARMING AND
LIGHT WINDS THAT WILL ALLOW FOR THE INVERSIONS TO SET UP.
THE REST OF THE WEEK THEN LOOKS BENIGN UNTIL THE NEXT WEEKEND WHEN
ANOTHER SHORTWAVE TAKES SHAPE ON THE HORIZON. OUR OPPORTUNITIES FOR
NEW SNOWFALL LOOK MEAGER THROUGHOUT THE END OF JANUARY AND INTO THE
BEGINNING OF FEBRUARY. HRICH
AVIATION
* LIGHT WINDS THIS MORNING WILL LINGER THROUGH THE DAY AS VFR
CONDITIONS ARE WIDESPREAD. WITH THE RECENT DRY AIR, FOG
