...NORTHERN/CENTRAL ROCKIES...

SNOW WILL CONTINUE TO BE POSSIBLE IN THE HIGHER ELEVATIONS OF THE
NORTHERN/CENTRAL ROCKIES FRIDAY INTO SATURDAY AS AN ANOMALOUS
UPPER LOW BEGINS TO LIFT NORTHEASTWARD OUT OF THE WESTERN U.S..
THE COMBINATION OF LOWERING TEMPERATURES/SNOW LEVELS AND ENHANCED
LIFT FROM STRONG DIVERGENCE WITHIN A LEFT EXIT REGION OF AN UPPER
JET SHOULD ALLOW FOR PERIODS OF HEAVY SNOW WHILE THE 700MB TRACKS
THROUGH NORTHWESTERN WYOMING FRIDAY NIGHT...BUT THEN SNOW ACROSS
THE ROCKIES SHOULD BEGIN TO DIMINISH BY SATURDAY EVENING AS THE
SYSTEM PROGRESSES OUT INTO THE NORTHERN PLAINS.  A GENERAL
CONSENSUS BLEND OF FAIRLY AGREEABLE MODEL GUIDANCE INDICATED THE
GREATEST PROBABILITIES FOR MORE THAN 8" OF SNOW WILL FOCUS ALONG
THE WIND RIVER/TETONS/ABSAROKA RANGE.  ACCUMULATING SNOW WILL ALSO
BE POSSIBLE IN THE HIGHER ELEVATIONS OF NORTH CENTRAL
COLORADO...UINTA MOUNTAINS OF NORTHERN UTAH...AND EVENTUALLY THE
BIGHORN MOUNTAINS IN WYOMING.
