DISCUSSION
BRR! IT'S BRISK OUT THERE. ADMITTEDLY, IT'S BEEN PRETTY NICE AS OF
LATE AND THESE MODERATELY COLDER TEMPERATURES CAN'T HOLD A CANDLE TO
THE DEEP FREEZE FOR THE EASTERN HALF OF THE COUNTRY.
EASTERLY RIDGE WIND GUSTS HAVE BEEN WELL OVER 50-60 MPH FOR MUCH OF
THE HIGHEST TERRAIN TODAY WITH SEVERAL REPORTS OF WIND HOLDS AT
LOCAL SKI AREAS. THE WINDS WILL PERSIST THROUGH MUCH OF THE
AFTERNOON AND EVENING WITH DECREASING SPEEDS INTO SUNDAY MORNING.
BACKCOUNTRY RECREATION AND AVIATION IMPACTS ARE EXPECTED FOR MUCH OF
TODAY, ESPECIALLY FOR AREAS ALONG AND WEST OF THE SIERRA CREST.
SURFACE BREEZES IN THE LOWER VALLEYS AND FOOTHILLS WON'T BE QUITE
AS STRONG WITH GUSTS 15 TO 20 MPH AT MOST, BUT THE BREEZES WILL
CONTRIBUTE TO THE CHILL.
PLAN ON WEAK HIGH PRESSURE FOR SUNDAY INTO TUESDAY WITH A RETURN OF
LIGHT WINDS AND INVERSIONS. ANOTHER TROUGH APPROACHES THE EASTERN
PACIFIC BY TUESDAY, BUT THE ENSEMBLES CLUSTERS ARE ON THE STRUGGLE
BUS WITH THE TRACK/TIMING. ONLY 23% OF THE SOLUTIONS SHOW THE TROUGH
TRACKING IN ACROSS NORTHERN CA, WHILE THE OTHERS ARE AN ARRAY OF DRY
RESULTS FOR THE NORTHERN SIERRA AND WESTERN NV, INCLUDING THE
TROUGH BECOMING A CUTOFF LOW DROPPING TOWARD SOCAL. BLENDED
GUIDANCE HAS A 10-20% CHANCE FOR PRECIPITATION RIGHT ALONG THE
SIERRA CREST. THIS IS NOT THE SNOW MAKER THAT WE'RE LOOKING FOR.
THE RIDGE RESUMES RESIDENCY FOLLOWING THIS LITTLE SHORTWAVE TROUGH
PASSAGE, WITH NO BIG SIGNALS FOR SOMETHING MORE PROLIFIC FOR OUR
LATITUDE. THERE ARE A FEW WAVES OF MOISTURE FORECAST TO SWEEP INTO
THE PACIFIC NORTHWEST, BUT THE IVT MOISTURE PLUME PROBABILITIES
ARE LOOKING RATHER DIRE FOR THE SIERRA AND WESTERN NEVADA.
SIMILARLY, THE 8-14 DAY OUTLOOKS ARE ALSO THE DRY AND WARM SIDE.

AVIATION
* COLDER, DRIER AIR HAS BROUGHT VFR CONDITIONS TO MOST SIERRA AND
NEVADA TERMINALS TODAY AFTER THE PATCHY LOW CLOUDS FROM THIS
MORNING. THE VERY DRY, COLD AIR WILL LIKELY LIMIT FOG FORMATION
(LESS THAN 5% CHANCE) AT KTRK FOR TONIGHT INTO EARLY SUNDAY.
* PRIMARY CONCERN FOR AVIATORS WILL BE THE STRONG NE-E FL100 WINDS
25-35 KTS THROUGH 06Z SUNDAY. EASTERLY SURFACE WIND GUSTS WILL BE
LIMITED TO AROUND 10-20KTS THROUGH 03Z SUNDAY. LOCALIZED AREAS OF
LLWS AND TURBULENCE POSSIBLE ALONG AND WEST OF THE SIERRA CREST.
* INVERSIONS WILL RETURN SUNDAY THROUGH TUESDAY WITH LIGHT SURFACE
WINDS AND A DRY FORECAST.
