CURRENTLY QUASI-ZONAL FLOW IS PRESENT IN THE NORTHERN PLAINS,
WITH A SLIGHT NORTHWEST TILT. THERE'S A SLIGHT RIDGE AXIS MOVING
THROUGH THE PACIFIC NORTHWEST. THE SLIGHT NORTHWEST TILT WILL
KEEP THE COOLER TEMPERATURES TO OUR EAST THROUGH THE EARLY PART
OF THIS WEEK. AT THE SURFACE A WARM FRONT ALONG A SURFACE TROUGH
MOVED THROUGH TODAY, LEAVING BREEZY WINDS AND TEMPERATURES IN
THE 30S TO 50S.
MONDAY WILL BE MORE OF THE SAME WITH TEMPERATURES WELL ABOVE
NORMAL FOR JANUARY. MONDAY NIGHT A PASSING CLIPPER WILL TIGHTEN
THE PRESSURE GRADIENT ACROSS THE STATE, AND SWEEP DOWN A BACK
DOOR COLD FRONT AFTER MIDNIGHT. THE COLD FRONT, HOWEVER, WILL
NOT AFFECT TEMPERATURES MUCH, IT WILL JUST CREATE ADVISORY
LEVEL WIND GUSTS EARLY TUESDAY THROUGH TUESDAY AFTERNOON. WE
SLIGHTLY BUMPED UP THE NBM WINDS WITH A BLEND OF THE 90TH
PERCENTILE FOR THIS PERIOD. ALOFT THE FLOW WILL BE OUT OF THE
NORTH, WITH AN AREA OF HIGHER HEIGHTS OVER THE WEST COAST
THROUGH SATURDAY. THURSDAY INTO FRIDAY COULD FEATURE THE NEXT
ROUND OF LIGHT SNOW WITH ANOTHER CLIPPER SYSTEM. WINDS WILL
INCREASE AGAIN, THE ECMWF EFI SUGGEST LESS THAN HIGH WIND
WARNING WINDS FOR NOW.
A GREAT AMOUNT OF UNCERTAINTY REMAINS ON HOW THE WEEK WILL END.
WITH THAT CLIPPER SYSTEM THE MODELS VARY, AND IT IS EVEN
AFFECTING THE TEMPERATURE FORECAST. THE NBM TEMPERATURE SPREADS
RANGE FROM THE LOWER TEENS TO THE LOWER 30S FOR ANY GIVEN LOCATION.
THE NEWEST DETERMINISTIC NBM RUN HAS KEYED IN ON THE LOWER END
OF THAT RANGE. HIGHS ARE FORECAST IN THE NBM TO BE IN THE TEENS
AND MID 20S FRIDAY, WHICH IS WHY THE PRECIP IS ONLY SNOW NOW.
THIS WILL BE SOMETHING WE CONTINUE TO WATCH, EITHER WAY
TEMPERATURES WILL BE NEAR NORMAL TO END THE WEEK.
