UPPER LEVEL RIDGING WILL BE THE DOMINANT FEATURE FOR COLORADO
WEATHER THROUGH THE NEXT WEEK. INITIALLY THE RIDGE IS OVER THE

OVER THE WEEKEND THE UPPER RIDGE BUILDS OVER THE GREAT BASIN AND
NORTHWEST FLOW ALOFT BEGINS TO MODERATE. BY MONDAY AND TUESDAY THE
UPPER RIDGE IS CENTERED OVER THE STATE WITH LIGHT FLOW THROUGH
MOST LEVELS. THE WARMEST TEMPERATURES OF THE FORECAST PERIOD WILL
BE ON MONDAY AND TUESDAY AS THE RIDGE AXIS CROSSES OVER THE STATE.

DURING THE LATTER HALF OF NEXT WEEK THE RIDGE WILL BEGIN TO WEAKEN
AS AN UPPER LOW OVER NORTHERN BAJA CALIFORNIA MOVES NORTHWARD AND
THEN CROSSES THE GREAT BASIN AND ROCKY MOUNTAINS ON WEDNESDAY AND
THURSDAY. THE MOUNTAIN AREAS MAY PICK UP A LITTLE BIT OF SNOW AT
THAT TIME. TEMPERATURES OVER EASTERN COLORADO WILL ALSO COOL OFF A
LITTLE AS SOME COOLER AIR MOVES IN TO THE REGION FROM THE NORTHERN
PLAINS.
