SATELLITE ANALYSIS AND TRENDS...LATEST IR STLT IMAGERY SHOWS CLOUD TOP
TEMPS COOLING SLIGHTLY OVER SW MT/W ID/NW WY..YET STILL REMAIN RELATIVELY
WARM AT AROUND -36C.  OVER THIS SAME AREA..CLOUD TOPS HAVE BECOME MORE
TEXTURED IN APPEARANCE PER VIS..SUGGESTING THAT SNOWFALL RATES MAY BE
INCREASING.  MID-LVL FORCING FROM AN APPROACHING SHORTWAVE CURRENTLY
OVER NW MT..S/CENTRAL ID..N NV IS CONTINUING TO PRESS ESEWD.  UVVS MAY
ALSO BE INFLUENCED BY A JET STREAK THAT IS SEEN ROUNDING THE BASE OF THE
SHORTWAVE..PRESENTLY POSITIONED WSW-ENE OVER CENTRAL CA AND CENTRAL NV.
THIS JET STREAK IS EXPECTED TO BECOME MORE SW-NE ORIENTED OVER THE NEXT
FEW HOURS AND MOVE NEWD PLACING THE LEFT-EXIT REGION OVER E ID..NW WY..AND
CENTRAL MT THIS AFTERNOON. MOISTURE IS VERY LIMITED WITH THIS SYSTEM AS PW
VALUES ACROSS THE MT/N WY ARE BETWEEN 0.25-0.50" PER GOES SOUNDER DATA.
HEAVIEST SNOWFALL RATES SHOULD BE ALONG THE ABSAROKA MNT RANGE WITH UVVS
BEING ADDITIONALLY ENHANCED BY TERRAIN.  WITH DECENT DYNAMICS BUT NOT
MUCH MOISTURE TO WORK WITH SNOWFALL RATES MAY REACH UP TO 1.0" AT TIMES
THIS AFTERNOON AS MOD/HVY SNOWFALL SHOULD CONTINUE FOR THE NEXT FEW HOURS.
