WHATCOM COUNTY THE PRECIPITATION TYPE IS RAIN. AS THE COOLER AIR
SPILLS INTO MORE OF THE NORTHERN PORTION OF WESTERN WASHINGTON
SUNDAY THIS COULD CHANGE THE PRECIPITATION TO SNOW SUNDAY IN MORE
LOCATIONS IN THE NORTH PART OF WESTERN WASHINGTON. WEAK WEATHER
SYSTEMS MAY AFFECT THE AREA NEXT WEEK.

&&

.SHORT TERM...SATELLITE IMAGERY SHOWS SHORTWAVE EMBEDDED IN THE
NORTHWESTERLY FLOW ALOFT OVER THE NORTHERN PORTION OF WESTERN
WASHINGTON THIS EVENING. DOPPLER RADAR SHOWS PRECIPITATION AS FAR
SOUTH AS JUST WEST OF SHELTON WEST OF THE SOUND AND AS FAR SOUTH AS
MOUNT RAINIER EAST OF THE SOUND. WITH THE NORTHWESTERLY FLOW ALOFT
THE CENTRAL SOUND IS GETTING RAIN SHADOWED A LITTLE BIT. BELLINGHAM
HAS BEEN REPORTING SNOW FOR THE LAST FEW HOURS WHILE THE REMAINDER
OF THE OBSERVATION SITES WITH PRECIPITATION ARE JUST REPORTING RAIN
AT 05Z. TEMPERATURES AROUND BELLINGHAM ARE NEAR FREEZING WHILE THE
REMAINDER OF THE AREA IS REPORTING MID 30S TO LOWER 40S.

THE FORECAST PROBLEM FOR THE EVENING CONTINUES TO BE WHERE WILL THE
RAIN SNOW LINE END UP IN THIS SCENARIO. THE MODELS HAVE BECOME MORE
CONSISTENT IN THE LAST COUPLE OF RUNS WITH THE GENERAL IDEA OF THE
SHORTWAVE TONIGHT BECOMING STATIONARY OVER NORTHWESTERN WASHINGTON
LATER TONIGHT INTO SUNDAY. SUNDAY AFTERNOON INTO SUNDAY NIGHT A WARM
FRONT...CURRENTLY SHOWING SIGNS OF DEVELOPMENT OUT NEAR 135W...WILL
MOVE INTO WESTERN WASHINGTON SPREADING PRECIPITATION OVER THE ENTIRE
AREA. BOTH THE 00Z NAM AND GFS NOW HAVE THE SNOW LEVEL NEAR THE
SURFACE LINE STAYING NORTH OF THE SEATTLE AREA THROUGH SUNDAY NIGHT
WITH THE EXCEPTION OF THE NAM DIPPING IT DOWN BRIEFLY INTO THE
SEATTLE AREA SUNDAY EVENING. WEB CAMS SHOW THE SNOW IN BELLINGHAM IS
NOT STICKING TO THE ROADS YET BUT WITH THE DEW POINT AT
FREEZING...WINDS NORTHEAST...AND THE BELLINGHAM TO WILLIAMS LAKE
SURFACE GRADIENT BECOMING MORE NEGATIVE OVERNIGHT...EXPECT THE SNOW
TO START STICKING TO THE ROAD SURFACES OVERNIGHT INTO SUNDAY
MORNING. WITH THE SHORTWAVE BECOMING STATIONARY OVER THE NORTHERN
PORTION OF THE AREA TONIGHT INTO SUNDAY AND THE TEMPERATURES
REMAINING AT FREEZING WITH OUTFLOW NORTHEASTERLY WINDS THROUGH
SUNDAY NIGHT WILL UPGRADE THE WATCH TO A WARNING FOR WESTERN WHATCOM
COUNTY. PRECIPITATION DOES NOT LOOK TO BE MUCH AT THIS POINT BUT A
FAIRLY CONSISTENT LIGHT PRECIPITATION WILL RESULT IN 1 TO 2 OR 3
INCH ACCUMULATIONS FOR EACH OF THE NEXT THREE 12 HOUR PERIODS.

CURRENT BELLINGHAM TO WILLIAMS LAKE GRADIENT AT -5.9 MB. THE NAM
SURFACE PROG HAS IT AT -9 MB AT 06Z WITH THE GFS AT -11 MB. THIS IS
AN INDICATION THAT THE MODELS ARE TOO AGGRESSIVE IN SPILLING THE
COLD AIR OUT OF BRITISH COLUMBIA. MORE EVIDENCE FOR THE SNOW LEVEL
TO THE SURFACE LINE TO STAY NORTH OF THE SEATTLE AREA FOR THE MOST
PART THROUGH THIS SCENARIO LEAVING THE SNOW LEVEL AROUND 500 FEET.
CURRENT FORECAST HAS A WINTER STORM WATCH AS FAR SOUTH AS THE
EVERETT AREA. WITH THE BELLINGHAM TO WILLIAMS LAKE GRADIENT BECOMING
MORE NEGATIVE OVERNIGHT WILL I AM RELUCTANT TO TAKE THE WATCH DOWN
WITH THIS FORECAST PACKAGE. WILL LET IT RIDE FOR NOW AND IF THE
TREND OF THE MODELS OVERESTIMATING THE BELLINGHAM TO WILLIAMS LAKE
GRADIENT CONTINUES OVERNIGHT LOOK FOR AT LEAST PORTIONS OF THE WATCH
TO BE DROPPED IN THE MORNING FORECAST PACKAGE.

WARM FRONT DISSIPATING OVER WESTERN WASHINGTON MONDAY MORNING INTO
MONDAY AFTERNOON. BOTH THE 00Z NAM AND GFS SHOW ANOTHER WARM FRONT
MOVING INTO THE AREA MONDAY NIGHT. CURRENT FORECAST IS DRY FOR THIS
TIME FRAME. THE SOLUTION ON THE 00Z RUN IS A NEW ONE. FOR NOW WILL
LET THE DRY FORECAST RIDE AND SEE IF THE MODELS CONTINUE WITH THIS
IDEA IN THE NEXT RUN OR TWO.

WILL UPDATE THE FORECAST TO ADD A WINTER STORM WARNING FOR WHATCOM
COUNTY. THE REMAINDER OF THE FORECAST UNCHANGED. FELTON

.LONG TERM...PREVIOUS DISCUSSION FOLLOWS. SOLUTIONS HAVE FLOPPED
AROUND FROM DRY AND COOL TO MILD AND WET. THE FORECAST IS
BROADBRUSHED WITH CHANCE TO LIKELY POPS. WE MAY SEE A WARM FRONT
AROUND WEDNESDAY...BUT AFTER THAT SYSTEMS MIGHT GO INTO CALIF AND
PRETTY MUCH AVOID THE PACNW FOR THE LATTER HALF OF THE WEEK BUT I
HAVE NOT DONE THAT TO THE FORECAST YET.

&&

.HYDROLOGY...RIVERS ACROSS WESTERN WASHINGTON WILL CONTINUE TO
RECEDE AND FLOODING IS NOT EXPECTED THROUGH NEXT WEEK.

&&

.AVIATION...A TROUGH OVER B.C. IS GENERATING RAIN OVER WESTERN WA
TONIGHT...WITH RAIN/SNOW AT KBLI. THE FLOW ALOFT IS NORTHWESTERLY.
NE FRASER RIVER OUTFLOW WILL INCREASE ON SUN WHILE A WARM FRONT
SPREADS MORE MOISTURE THROUGH WESTERN WA. KCLM AND KBLI MAY SEE MORE
SNOW...WITH A RAIN/SNOW MIX POSSIBLE AT KPAE. PRECIP ALONG THE COAST
AND TERMINALS SOUTH OF KPAE SHOULD STAY AS RAIN. MVFR TO IFR
CONDITIONS ARE EXPECTED THROUGHOUT THE PERIOD. 33

KSEA...LIGHT RAIN AND MVFR CONDITIONS EXPECTED TONIGHT THROUGH
SUNDAY. SOUTH WINDS AT THE SURFACE...POSSIBLE SWITCHING TO THE NORTH
00Z MON. 33

.MARINE...A WEAK SURFACE LOW OVER VANCOUVER ISLAND WILL CLIP THROUGH
W WASHINGTON TONIGHT. WINDS OVER THE COASTAL WATERS ARE BORDERLINE
SMALL CRAFT ADVISORY. MEANWHILE...NE PRES GRADIENTS WILL INCREASE
TONIGHT AS HIGH PRES BUILDS OVER INTERIOR B.C. EXPECT STRONG FRASER
RIVER OUTFLOW SUN AND SUN NIGHT WITH NE/E GALES OVER THE NORTHERN
