WEAK HIGH PRESSURE RIDGES THROUGH WYOMING.  THE PRECIPITATION WILL
INCREASE IN THE WESTERN MOUNTAINS ON SATURDAY EVENING AHEAD OF
ANOTHER LOW PRESSURE TROUGH AND COLD FRONT THAT WILL SPREAD MORE
PRECIPITATION EAST OF THE DIVIDE SUNDAY AND SUNDAY NIGHT.  THERE
SHOULD BE ENOUGH MOISTURE IN THE FLOW FOR MOUNTAIN SHOWERS ON MONDAY
WITH SOME SHOWERS IN NORTHWEST FLOW EAST OF THE DIVIDE AS WELL. WINDS
WILL REMAIN RATHER STRONG IN THE MOUNTAINS AND THE SOUTH...AND ALONG
THE EAST SLOPES OF THE MOUNTAINS AS WELL AS THROUGH THE WIND

AS WELL AND MAY SEE CHANGES IN TIMING THROUGH THE EXTENDED FORECAST
THE NEXT SEVERAL DAYS.  THIS IS ALREADY SHOWING UP WITH THE DELAY OF
PRECIPITATION MOVING INTO THE WEST ON SATURDAY. AT THIS TIME THE
