SATELLITE ANALYSIS AND TRENDS...LATEST WV IMAGERY SHOWS THAT UPPER LOW
WAS CENTERED OVER PORTIONS OF NE CO THIS AFTERNOON.  A SECOND PIECE OF
ENERGY/CIRCULATION APPEARED TO BE STARTING TO LIFT OUT OF THE BASE OF
THE TROF AND THE COMBINATION OF THIS AND UPSTREAM HEIGHT FALLS PUSHING
THROUGH THE N ROCKIES SHOULD BEGIN TO ALLOW SYSTEM TO DEVELOP E LATER
THIS EVENING.  BEFORE THEN THOUGH, MID LEVEL DEFORMATION AXIS/COMMA HEAD
HAS SHOWN A SIGNIFICANT AMOUNT OF ENHANCEMENT OVER THE LAST FEW HOURS IN
RESPONSE TO INCREASING FRONTOGENESIS NEAR ENTRANCE REGION OF DOWNSTREAM
JET STREAK AND ALSO WITHIN A FAVORABLE AREA OF INCREASING DEFORMATION WITH
APPROACH OF UPSTREAM HEIGHT FALLS.  MOST RECENT NOAA-19 PASS WAS SHOWING
AN AXIS OF LIGHT TO MODERATE SNOWFALL EXTENDING FROM CARBON COUNTY IN S WY
S TO VIC OF MINERAL COUNTY IN SW CO.  AREAL AVERAGE SNOWFALL RATES WITHIN
THIS AXIS WERE MAXING OUT BETWEEN 0.8-1.0"/HR  IN THE VIC OF S CARBON
COUNTY, N ROUTT AND NE MOFFAT COUNTIES.  CYCLONIC DRY CONVEYOR BELT WAS
WRAPPING BACK INTO THIS REGION IMPLYING A LOWERING OF EPV WITHIN AN AREA
OF ENHANCED MID LEVEL LAPSE RATES.  THIS WOULD TEND TO FAVOR CONTINUING
HEAVY SNOWFALL WITHIN THIS AXIS AND FAVORED ALONG THE LEADING EDGE OF
BEST CLOUD TOP COOLING FROM VIC OF CONVERSE COUNTY IN E WY EXTENDING SW
TO VIC OF ROUTT COUNTY IN NW CO.  WOULD EXPECT SNOWFALL RATES IN THE HIGH
ELEVATIONS WITHIN THIS AXIS TO MAX OUT AT OVER 1.0"/HR WITHIN FAVORED
NNE/SSW ORIENTED BANDS BEFORE SYSTEM BEGINS TO EJECT E LATER THIS EVENING.
