What forecasters said that day

The local office's own words before this high wind watch went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Medford, OR wrote its last area forecast discussion before this high wind watch went out at Dec 20, 1:30 PM PST, 1 hour 5 minutes earlier.

Area forecast discussion, Dec 20, 1:30 PM PST, 1 hour 5 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
130 PM PST TUE DEC 20 2005

.DISCUSSION...12Z NGM/NAM/GFS IN.

THE NEAR TERM FORECAST CALLS FOR RELATIVELY WARM AND WET WEATHER.
THE LONGWAVE PATTERN IS STAGNANT WITH A BROAD TROUGH OFF THE WEST
COAST AND RIDGING OVER THE ROCKIES.  THIS MAKES FOR PERSISTENT
MOIST SOUTHWEST FLOW ALOFT OVER THE MEDFORD CWA.  EMBEDDED SHORT
WAVES MOVING THROUGH THE TROUGH AND NORTH ALONG 130W WILL PUSH
SEVERAL WARM FRONT/COLD FRONT COMBOS ONSHORE...ONE AS WE SPEAK...
AND ONE EACH ON WEDNESDAY AND THURSDAY.

WATER VAPOR IMAGERY SHOWS QUITE A BIT OF MOISTURE ADVECTING INTO THE
AREA...AND THE AIR COMING IN IS QUITE WARM...DRIVING UP THE SNOW
LEVEL.  AFTER FURTHER EVALUATION...THE POTENTIAL FOR FLOODING IS
LOW...SO THE FLOOD WATCH WAS CANCELLED EARLIER TODAY.  A HIGH WIND
WARNING VERIFIED ALONG THE COAST TODAY...BUT NOT YET IN THE SHASTA
VALLEY.  WILL CANCEL THE HIGH WIND WARNING IN THE SHASTA VALLEY AND
THE WIND ADVISORY FOR THE BEAR CREEK VALLEY WITH THE ZONE ISSUANCE.
WILL ALSO ISSUE A HIGH WIND WATCH FOR THE COAST FOR THE WEDNESDAY
SYSTEM. THE THURSDAY FRONT LOOKS TO BE EVEN WINDIER.

THE RIDGE WILL WEAKEN THURSDAY AND MOVE ON TO THE EAST...AND THE
OFFSHORE TROUGH WILL ALSO WEAKEN TEMPORARILY.  EXPECT A BREAK IN THE
ACTION FRIDAY AND SATURDAY AS AN UPPER RIDGE BUILDS ALONG THE WEST
COAST.  IT NOW LOOKS LIKE THE RIDGE WILL HANG TOUGH THROUGH MONDAY.
HOWEVER...THE UPSTREAM TROUGH WILL ALSO RETRENCH DURING THIS PERIOD
AND THE WET PATTERN WILL BEGIN ANEW AT SOME POINT NEXT WEEK.  THE
RIDGE WILL BREAK TO THE EAST AND SHORT WAVES EJECTING FROM THE
OFFSHORE TROUGH WILL START PUSHING FRONTS ONSHORE AGAIN.
