AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
330 PM PST SUN FEB 25 2007
.UPDATE...SHORT UPDATE TO REMOVE HEADLINES FOR WINTER HIGHLIGHTS SET
TO EXPIRE AT 4 PM.
&&
.PREVIOUS DISCUSSION.../ISSUED 245 PM/
SHORT TERM...AN UPPER LEVEL LOW IS LOCATED OFF THE PACNW COAST WITH
COLD AIR AND CONTINUING SHOWERS MOVING INTO THE REGION TODAY BEHIND
THE COLD FRONT. THIS UPPER LOW IS FORECAST TO REMAIN OFF THE COAST
THROUGH TUESDAY BEFORE SHIFTING INLAND ON WEDNESDAY.
THIS AFTERNOON...RADAR IMAGERY SHOWS CONTINUING CONVECTIVE SHOWERS
ACROSS THE AREA WITH SCATTERED MODERATE SHOWER ACTIVITY OVER THE
WEST SIDE ESPECIALLY IN THE CASCADES...SISKIYOUS AND THE WESTERN
HALF OF SISKIYOU COUNTY. THE 12Z NAM AND GFS SHOW CONTINUING UPPER
LEVEL SUPPORT WITH A 150 KT JET OVER THE REGION TODAY INTO TONIGHT.
AS WEAK SHORTWAVES ROTATES THROUGH THE FLOW THIS AFTERNOON AND
EVENING WILL CONTINUE TO SEE WIDESPREAD SHOWERS OVER THE AREA. ALSO
COLD AIR AND SOME INSTABILITY OVER THE REGION WILL ALLOW FOR SOME
ISOLATED LIGHTNING IN HEAVIER SHOWERS MAINLY ALONG THE COAST AND
OVER THE MARINE WATERS. SNOW LEVELS ARE CURRENTLY AROUND 2000 FEET
AND LOCALLY LOWER...SNOW LEVELS ARE FORECAST TO GRADUALLY LOWER
TONIGHT WITH DOWN TO 1000 FEET BY MONDAY MORNING. LATE TONIGHT A
STRONGER SHORTWAVE ROTATES AROUND THE LOW BRINGING A WEAK FRONT TO
THE CWA ALLOWING FOR INCREASED WIDESPREAD MODERATE SHOWER ACTIVITY
OVER THE AREA THROUGH MONDAY MORNING.
THE MAIN CONCERN FOR TODAYS FORECAST REMAINS THE SNOW ACCUMULATIONS
IN SHOWER ACTIVITY. LOWERING SNOW LEVELS WILL ALLOW SNOW
TO REACH VALLEY FLOORS TONIGHT INTO MONDAY MORNING WITH LIGHT
ACCUMULATIONS POSSIBLE OVER THE WEST SIDE VALLEYS...GENERALLY EXPECT
1 TO 3 INCHES OF SNOW OVER THESE VALLEYS. MONDAY AFTERNOON
THE UPPER LEVEL JET SHIFTS TO THE SOUTH AND EAST...SO EXPECT
DECREASED SHOWER INTENSITY OVER THE CWA.
NAM AND GFS INDICATE THAT THE UPPER LOW REMAINS ALONG THE COAST AND
GRADUALLY SHIFTS SOUTHWARD MONDAY NIGHT BEFORE SHIFTING INLAND LATE
TUESDAY INTO WEDNESDAY. AS THE SURFACE LOW ASSOCIATED WITH THIS
SYSTEM MOVES INTO THE COAST LATE MONDAY INTO TUESDAY
MORNING...EXPECT AN INCREASED CHANCE FOR ORGANIZED SHOWER ACTIVITY.
ALOFT THE UPPER LEVEL SUPPORT REMAINS WEAK THROUGH THIS PERIOD
THOUGH. THE CONTINUED COLD AIR MASS WILL KEEP SNOW LEVELS LOW ACROSS
THE AREA...SO ANY ORGANIZED SHOWERS MAY BRING A CHANCE FOR SNOW
ADVISORY CONDITIONS...WILL NEED TO MONITOR EXPECTED SNOWFALL
ACCUMULATIONS.
LONG TERM...WEDNESDAY THROUGH SUNDAY...ECMWF AND GFS MODELS ARE NOT
IN GOOD AGREEMENT BEYOND THURSDAY AND GFS-ENSEMBLE MODEL SHOWS
INCREASING FORECAST MEMBER SPREAD FRIDAY THROUGH THE WEEKEND.
THEREFORE...LOW CONFIDENCE IN FORECAST NEXT WEEKEND.
WEDNESDAY THROUGH FRIDAY...GENERALLY MOIST RIDGE WILL HOLD OVER THE
EASTERN PACIFIC WITH INTERMITTENT DISTURBANCES MOVING OVER THE BACK
SIDE OF THE RIDGE AND INTO THE PACIFIC NORTHWEST.
GFS MODEL SHOWS A WETTER TROUGH-LIKE SOLUTION FOR NEXT
WEEKEND...THOUGH THE ECMWF SHOWS RIDGE OVER THE WEST...MADE FEW
CHANGES TO PREVIOUS FORECAST.
&&
.AVIATION...UNSTABLE ATMOSPHERE IS PRODUCING WIDESPREAD SHOWERS WITH
FREEZING LEVEL GENERALLY BELOW 2000 FEET AGL. CONDITIONS ARE
GENERALLY VFR TO MVFR OUTSIDE OF SHOWERS BUT IFR WITHIN SHOWERS. IN
ADDITION...SHOWERS REMAIN QUITE INTENSE WITH THIS SYSTEM AND EVEN
GETTING LIGHTNING STRIKES OCCURRING NEAR THE COAST.
