SATELLITE ANALYSIS AND TRENDS...CONVECTIVE BAND WITH COMMA CLOUD
ASSOCIATED WITH NE OREGON VORT PRODUCING HV SNOW BURSTS WITH QUICK
MOVING PART OF THE COMMA TAIL THRU INTERIOR N TO NORTHERN PORTION OF
CENTRAL IDAHO.  WHERE ENHANCEMENT MORE PERSISTENT...CLOUD TOPS NOT AS
COLD AND A LITTLE MORE FRAGMENT...AS PER SE WA...SO LIGHTER SNOW RATES
THERE BUT MORE PERSISTENT IN THEIR LIGHT SNOW RATES.  IN ANY CASE AS
STATED EARLIER...SOME 0.4-0.5" PW VALUES LIKELY TO HAVE BEEN ENTRAINED
INTO VORT COMMA AND TAIL AND EVEN IF THESE MOISTURE VALUES DROP BECAUSE
OF HIGHER ELEV EFFECTS...OROGRAPHIC LIFT WITH TAKE UP THE SLACK AS
COMMA APPROACHES MT-ID BORDER AND THEN MOVES ACROSS W CENTRAL MONTANA
OVERNIGHT.   HPC SNOW FORECAST LOOKS REASONABLE AND MOST OF THIS SNOW
IS ASSCIATED WITH THIS VORT AND PARENT LOW/VORT SPINNING ACROSS NE WA.
WILL CONTINUE TO MONITOR...
