EVENT...DYNAMICS LATCHING ON TO LIMITED MOISTURE...
.
SATELLITE ANALYSIS AND TRENDS...MAIN TROUGH FROM WATER VAPOR LOOP
FROM CENTRAL MONTANA THRU INTERIOR WESTERN WY/E UTAH.  MINOR VORT ON W
SIDE OF TROUGH SPREADING LIGHT SNOW E IDAHO INTO TETON COUNTY OF WY.
MORE IMPORTANT DEVELOPMENT WITH DEVELOPING VORT CENTRAL TO N CENTRAL
WY WHERE COOL TOPS HAVE ORGANIZED INTO A SEMI COMMA CLOUD FOR STEADY
LIGHT PRECIP/SNOW.  PIVOT AREA NEAR PARK TO BIG HORN COUNTY. PROBLEM
IS WILL THE DYNAMICS MAKE UP FOR SLOW DECREASE IN PW MOISTURE...OR WILL
SLOW DECREASE IN PW MOISTURE THE NEXT SEVERAL HRS WIN OUT TO KEEP SNOW
ON THE LIGHT SIDE.  BETTER COOLING CLOUD TOPS OCCURRING NW WY CLOSER TO
BETTER MOISTURE...BUT COMMA LOOKING BETTER FOR MORE PERSISTENT STEADY
LIGHT PRECIP THAT COULD INCREASE A BIT IN THE NEXT FEW HRS IN THE VIC
OF BIG HORN...WASHAKIE TO SHERIDAN COUNTY (WY)/BIG HORN COUNTY (MT).
EXPECT A SLOW SHIFT EAST NEXT 3-6HRS...BUT WITH HIGHER PWS SHIFTING
EAST AND SLIGHT LOWERING OF MOISTURE COMING IN FROM THE WEST...WILL BE
HARD FOR AMOUNTS TO BE GREATER THAN 0.25" IN THE 6-12Z TIME FRAME...BUT
COULD BE SOME ISOLATED 0.25" OR SLIGHTLY HIGHER AMOUNTS ESPECIALLY HIGHER
ELEVS BASED ON STRENGTHEN DYNAMICS.
WILL CONTINUE TO MONITOR...
