.DISCUSSION...00Z NGM/NAM/GFS IN.

SATELLITE IMAGERY SHOWS A VERY WRAPPED UP LOW NOW ONSHORE OVER

CALIFORNIA.

THE LARGE-SCALE PATTERN WILL CHANGE LITTLE OVER THE COMING WEEK
WITH A STRONG LOW NEAR HUDSON BAY...A MEAN UPPER TROUGH OFF THE
WEST COAST...AND A BROAD FLAT RIDGE OVER MOST OF THE U.S. THIS
SUGGESTS AN OVERALL WET PATTERN FOR THE MEDFORD CWA WITH WARMER
THAN NORMAL TEMPERATURES.

FLOW...THE COAST...COAST RANGE...THE SISKIYOUS AND...TO A LESSER
EXTENT...THE CASCADES. SNOW LEVELS WILL BE QUITE HIGH TOO.

ENERGY DIVING DOWN THE BACKSIDE OF THE LONG WAVE TROUGH WILL
CAUSE IT TO REDIG OFFSHORE BEGINNING THIS AFTERNOON. EVENTUALLY
THE TROUGH WILL SHEAR AND THE CUTOFF LOW WILL MOVE SLOWLY
EAST...OVER NORTHERN OREGON THURSDAY NIGHT. THE ASSOCIATED FRONT
WILL MOVE IN THURSDAY.  WHILE THIS WILL PUSH THE STALLED FRONT OUT
OF THE AREA...IT WILL ALSO BRING ANOTHER ROUND OF PRECIPITATION

FROM THE SOUTHWEST. MORE SYSTEMS...ABOUT 24 HOURS APART...WILL
