.DISCUSSION...
CLASSIC FALL-LIKE (TECHNICALLY AUTUMN DOESN/T BEGIN UNTIL 903 PM PDT
THIS EVENING) NORTH WIND EVENT HAS DEVELOPED ON SCHEDULE OVERNIGHT.
THE HIGHLY AMPLIFIED UPPER PATTERN WITH A STRONG RIDGE OVER THE
EASTERN PACIFIC AND A COLD UPPER LOW OVER THE ROCKIES WILL CONTINUE
TO SUPPORT BREEZY TO WINDY CONDITIONS OVER NORTHERN CALIFORNIA INTO
THE WEEKEND.

NORTHERLY SURFACE PRESSURE GRADIENTS HAVE INCREASED DRAMATICALLY
OVERNIGHT AND ARE NOW AROUND 14 MBS FROM MEDFORD TO SACRAMENTO. KDAX
VWP HAS SHOWED A STEADY INCREASE IN WINDS ABOVE THE SURFACE THROUGH
THE NIGHT WITH WINDS CURRENTLY RANGING FROM 45 KNOTS TO 60 KNOTS IN
THE LAYER FROM 1000 FEET TO 5000 FEET ABOVE THE SURFACE.

STILL APPEARS THAT THE PEAK OF THE STRONGEST WINDS IN THE SACRAMENTO
VALLEY WILL OCCUR AROUND MIDDAY TODAY AS SURFACE GRADIENTS MAX
OUT...ALIGNMENT OF UPPER WINDS BECOMES IDEAL...AND SOME COLD
ADVECTION HELPS TO MIX DOWN THE STRONGER WINDS ABOVE THE SURFACE.
SLOW WEAKENING OF WINDS MAY OCCUR DURING THE AFTERNOON. PEAK GUSTS
IN THE 40 TO 50 MPH RANGE WILL BE POSSIBLE ESPECIALLY ON THE WEST
SIDE OF THE VALLEY ALONG INTERSTATE 505 AND INTERSTATE 5 NORTH OF
WOODLAND.

THE MAIN SHORT-TERM CONCERNS WILL CONTINUE TO BE CENTERED AROUND THE
HIGH FIRE DANGER POSED BY THE STRONG WINDS...LOW HUMIDITIES AND DRY
VEGETATION. KDAX RADAR HAS SHOWN A STEADY INCREASE IN THE SMOKE
PLUME THE PAST SEVERAL HOURS ORIGINATING FROM THE FIRE BURNING IN
YOLO COUNTY TO THE WEST OF WOODLAND WHICH WAS FIRST REPORTED AROUND
1230 AM.

LOOKS LIKE THE STRONGEST SURFACE GRADIENTS WILL BECOME MORE
NORTHEASTERLY OR EASTERLY TONIGHT AND SATURDAY WHICH WILL SHIFT THE
FOCUS OF STRONGEST WINDS INTO THE CANYONS ALONG THE WEST SLOPES OF
THE NORTHERN SIERRA NEVADA. BREEZY CONDITIONS WILL ALSO LIKELY
CONTINUE IN LAKE COUNTY AND LOCALLY ALONG THE WEST SIDE OF THE
SACRAMENTO VALLEY. BY SUNDAY...APPEARS THE AMPLIFIED PATTERN WILL BE
BREAKING DOWN AND THE EASTERLY SURFACE GRADIENT WILL RELAX.  DFR
