EVENT...DYNAMICS AND FILTERED CONVEYOR BELT MOISTURE FOR LOCAL HVY
SNOW BURSTS...
.
SATELLITE ANALYSIS AND TRENDS...NARROW DECENT ENOUGH MOISTURE TRANSPORT
WITH MOISTURE PLUME FROM N PLAINS BEING ADVECTED INTO MONTANA AND BACK
INTO CENTRAL WYOMING.  MAY BE A LITTLE SEEPAGE OF THAT MOISTURE BACK INTO
SW MONTANA...E IDAHO AND W WYOMING THAT IS CONTRIBUTING TO OCCASIONAL HVY
SNOW BURSTS...ESPECIALLY HIGHER ELEVATIONS JUST AHEAD OF UPPER TROUGH
NOW FAR WESTERN MONTANA THRU E IDAHO.  COOLING CLOUD TOPS NOTED TETONS
THRU YELLOWSTONE IN NW WY INTO SW MONTANA FROM E CENTRAL
IDAHO.  IT IS CONCEIVABLE HIGHEST ELEVATIONS HERE COULD BE PICKING UP A
QUICK 0.5 TO 1.0 INCH OF SNOW.  SAME DEAL WITH ENHANCEMENT JUST TO THE
EAST AND SE ACROSS INTERIOR WEST TO CENTRAL WY...BUT HERE SFC TEMPS A BIT
WARMER....SO SNOWFALL AT A HIGHER ELEVATION.   17Z SATELLITE WINDS HAD A
MAX WIND/JET OF 120KTS OVER W WA INTO NW OREGON AND THAT COULD HELP DEEPEN
THE TROUGH A BIT FOR THE OVERNIGHT PERIOD...MAKING SNOW MORE WIDESPREAD.
WILL CONTINUE TO MONITOR...
