SATELLITE ANALYSIS AND TRENDS...LATEST WV IMAGERY INDICATES THAT LARGE
SCALE PATTERN FEATURED ANOMALOUS TROF CONTINUING TO AMPLIFY INTO THE
PAC NW IN RESPONSE TO STRONG JET ALONG ROUGHLY 131W.  JUST DOWNSTREAM OF
INCREASINGLY ANOMALOUS TROF, A NUMBER OF EJECTING IMPULSES WERE WITHIN
SUBTROPICAL MOISTURE STREAM AND LIFTING NE.  THE LEAD IMPULSE WAS FROM
FAR NE WY WITH TROF AXIS EXTENDING S INTO PORTIONS OF NE CO WHILE JUST
UPSTREAM A SECOND IMPULSE WAS NOTED FROM NW WY WITH TROF AXIS EXTENDING
INTO NW CO.  THE  COMBINATION OF THESE LIFTING IMPULSES AND DOWNSTREAM
JET STREAK WAS ALLOWING FOR AN INCREASED AREA OF ISENTROPIC ASCENT TOWARDS
RIGHT ENTRANCE REGION OF JET STREAK.  LATEST BLENDED PW ANALYSIS AND AREA
GPS DATA WAS SUGGESTING THAT PW VALUES CONTINUE TO INCREASE OVER THE N
PLAINS WITH RECENT POLAR MICROWAVE PRODUCTS INDICATING A WELL DEFINED E
PAC SUBTROPICAL MOISTURE FEED FROM TS FRED.  HAVE BEGUN TO NOTICE SOME
ENHANCING CLOUD TOPS WITH DEVELOPING CONVECTIVE ACTIVITY IN THE VIC OF GDV
AND ALSO OVER FAR SE PORTIONS OF SASKATCHEWAN SE OF CWIK.  WOULD EXPECT
THAT THIS TREND SHOULD CONTINUE OVER THE NEXT FEW HOURS AS INCREASED
LARGE SCALE FORCING CONTINUES TO OVERSPREAD THE AREA.  DESPITE THE RATHER
ANOMALOUS MOISTURE IN PLACE OVER THE REGION, THICKNESSES AND 70H TEMPS
WERE QUITE HIGH ON 0Z UA ANALYSIS PROVIDING SOME UNCERTAINTY AS TO THE
AMOUNT OF CONVECTIVE COVERAGE INTO THE MORNING HOURS.  THESE MITIGATING
FACTORS WOULD TEND TO SUGGEST THAT ANY HEAVY RAIN THREAT SHOULD BE VERY
ISOLATED AND CONFINED TO ANY LOCATIONS WHERE BRIEF TRAINING IS POSSIBLE
OVER PORTIONS OF FAR NW ND.
