SATELLITE ANALYSIS AND TRENDS...WATER VAPOR AND ACCOMPANYING IR IMAGERY
SHOW THAT MID LEVEL CENTER OF SYSTEM NOW BEGINNING TO AFFECT THE WEST
COAST IS SOMEWHERE IN THE VICINITY OF 43N/131W.  TROF HAS SHARPENED
CONSIDERABLY OVER THE LAST 12-24 HRS AS A RESULT OF SHORTWAVE TROF
DROPPING INTO THE BASE OF THE TROF ALONG 135W.  GOES DERIVED 140KT
UPSTREAM JET STREAK SHOULD ENSURE THAT TROF CONTINUES TO DIG OVER THE
NEXT 6-12 HRS.
.
INFRARED CLOUD PATTERN APPEARS AS THOUGH IT IS IN THE PROCESS OF TAKING
ON A LOOSELY ORGANIZED BAROCLINIC LEAF PATTERN WHICH IS INDICATIVE OF
INCREASING LOW AND MID LEVEL FRONTOGENSIS.  THE INFERRED INFLECTION POINT
OF THE DEVELOPING LEAF APPEARS TO BE SOMEWHERE IN THE VIC OF 37N/129W.
.
LOW LEVEL FLOW HAS BACKED AND INCREASED SUBSTANTIALLY OVER THE LAST 6 HRS
OVER THE REGION WITH LOCAL VWPS SHOWING BEST LLJ BEING FOCUSED INTO THE
COASTAL RANGES OF NW CA AND SW OR.  MOST RECENT NOAA AMSU PASS (0437Z)
SHOWS THAT A 1.00-1.25" PRECIPITABLE WATER PLUME WAS COINCIDENT WITH
THE ABOVE MENTIONED LLJ AXIS AND THIS SHOULD ALLOW FOR THE BEST MOISTURE
FLUX ANOMALIES TO FOCUS OVER THE COASTAL RANGES OF SW OR/NW CA AND THE
SHASTA/SISKIYOUS REGIONS.  NOAA AMSU RAINFALL RATES GENERALLY LOOK TO
BE MAXING OUT AROUND 0.10"/HR AND THESE RATES AGREE WITH MOST RECENT
METARS IN THE REGION.  WOULD EXPECT SIMILAR RATES OVER THE NEXT FEW
HOURS WITH HIGHER RATES (UP TO 0.30-0.40"/HR) POSSIBLE IN THE NORMALLY
FAVORED OROGRAPHIC LOCATIONS IN THE AREA TO BE AFFECTED BY THE GREATEST
MOISTURE FLUX ANOMALIES.  WILL CONTINUE TO MONITOR.
