DISCUSSION
WEATHER PATTERN OVERVIEW:
A NEARLY ZONAL FLOW TODAY WILL TRANSITION INTO A DEEPENING TROUGH
ON FRIDAY AS SEVERAL SHORTWAVES PUSH THROUGH THE NORTHERN
ROCKIES. WITH THE AMPLIFYING FLOW, BY THE WEEKEND A RIDGE WILL
MOVE ACROSS THE WESTERN STATES.
A PACIFIC COLD FRONT BROUGHT LIGHT MIXED PRECIPITATION AND SOME
MIXING DOWN OF WESTERLY WINDS TODAY, BUT SURFACE INVERSION HAS
MOSTLY HELD IN PLACE. ANOTHER COLD FRONT MOVES THOUGH THURSDAY
NIGHT THAT WILL LOWER TEMPERATURES TO NEAR NORMAL FOR FRIDAY.
MOISTURE WILL STAY TO THE SOUTH AND WEST OF THE FORECAST AREA WITH
THESE SYSTEMS.
SATURDAY AND SATURDAY NIGHT, A WARM FRONT IS EXPECTED TO MOVE
EAST ACROSS THE AREA WHICH WILL BRING A RETURN TO ABOVE NORMAL
TEMPERATURES. IF SKIES CLEAR WITH LIGHT WINDS, NIGHTTIME FOG IS
POSSIBLE. AN UPPER RIDGE WILL PREVAIL EARLY NEXT WEEK WITH DRY
WEATHER.
FORECAST CONFIDENCE & DEVIATIONS:
BLENDED IN HIGHER RESOLUTION GUIDANCE AND BACKED OFF ON WINDS
HAVING DIFFICULTY MIXING DOWN THROUGH THIS EVENING. CONFIDENCE FOR
TEMPERATURES OVER THE NEXT WEEK IS HIGH FOR SUSTAINED MILD
CONDITIONS IN THE SOUTHWEST ZONES, WHILE MEDIUM FOR THE HI-LINE
WHERE LIGHT SNOW PACK LINGERS AND INVERSIONS ARE LIKELY.
