.SHORT TERM...UPDATES PLANNED BY 930...SHORT WAVE IS MOVING THRU THE
PACIFIC NORTHWEST. ITS APPROACH WILL CAUSE A STRONG INCREASE IN WINDS
OVERNIGHT ALONG WITH INCREASING CLOUD COVER. FORECAST LOOKS GOOD.
WILL RAISE A FEW TEMPS CONSIDERING CLOUD COVER AND THE EXPECTED
STRONG WINDS DURING THE NIGHT.

.EXTENDED...A WEAK RIDGE OVER THE ZONES ON THURSDAY. THE AIRMASS
STAYS DRY WITH A GOOD SURFACE GRADIENT IN PLACE FOR BREEZY CONDITIONS
THRU THE EXTENDED PERIOD. A DIFFERENCE BETWEEN THIS RUN OF THE MFR
AND THE PREVIOUS...BY FRIDAY THE NEW MRF IS DIGGING A SHARP TROF OVER
THE EASTERN PACIFIC WHILE THE OLD RUN HAD NEARLY ZONAL FLOW. THE
ECMWF AND UKMET ALSO HAVE THIS DEEPER TROF...ALTHOUGH THE ECMWF IS A
BIT SLOWER...AND THE UKMET IS SLOWER STILL.  THE MRF KEEPS THIS TROF
INTACT AND BRINGS IT OVER THE PACIFIC NW BY LATE SATURDAY AND ACROSS
THE ROCKIES EARLY SUNDAY. THIS TROF MAY ARRIVE SLOWER IF THE SLOWER
MODELS ARE CORRECT. THIS WOULD PRODUCE A WETTER...COOLER FORECAST.
FORECAST STILL LOOKS QUITE DRY EXCEPT FOR THE SOUTHWEST BUT TEMPS
WILL DROP ON SUNDAY. ZELZER
