COLORADO.

.DAY ONE...TODAY AND TONIGHT

SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE TO DEVELOP LATE
THIS MORNING OVR THE MOUNTAINS AND HIGH VALLEYS AND THEN SPREAD
OVER THE PLAINS THIS AFTERNOON. SHOWERS WILL BECOME MORE NUMEROUS
DURING THE AFTERNOON AS AN UPPER LEVEL DISTURBANCE MOVES ACROSS
THE STATE. EXPECT BRIEF HEAVY RAIN...SMALL HAIL AND GUSTY WINDS TO
40 MPH WITH THE STRONGER STORMS. SEVERE STORMS ARE NOT EXPECTED
TODAY WITH COOLER TEMPERATURES...LOWER MOISTURE VALUES AND LESS
SHEAR IN THE ATMOSPHERE AVAILABLE. THE SHOWERS WILL DECREASE FROM
WEST TO EAST THIS EVENING WITH GUSTY WINDS DEVELOPING ALONG THE
FRONT RANGE FOOTHILLS AND NEAR BY PLAINS.

OVER THE NORTH CENTRAL MOUNTAINS...THERE WILL BE SNOW
ACCUMULATION OF 2 TO 5 INCHES POSSIBLE IN THE HIGH COUNTRY ABOVE
10 THOUSAND FEET. THE HIGH MOUNTAIN PASSES MAY BECOME SLUSHY AT
TIMES AS SNOW SHOWERS PASS BY.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

A RIDGE OF HIGH PRESSURE WILL MOVE OVER COLORADO ON SUNDAY...BUT
ENOUGH MOISTURE AND INSTABILITY WILL BE AROUND IN THE AFTERNOON
FOR A CHANCE OF SHOWERS AND A FEW THUNDERSTORMS. A COLD FRONT WILL
MOVE INTO THE FRONT RANGE SUNDAY EVENING WITH A CHANCE OF SHOWERS
AND SOME STORMS AT THAT TIME. ON MONDAY...THERE WILL BE A CHANCE
OF SHOWERS AND THUNDERSTORMS IN THE MOUNTAINS...BUT THE PLAINS
WILL STAY RELATIVELY DRY. THE NEXT SYSTEM WILL BRING ANOTHER ROUND
OF PRECIPITATION TO MUCH OF NORTH CENTRAL AND NORTHEAST COLORADO
LATE MONDAY NIGHT THROUGH TUESDAY EVENING. WEDNESDAY THROUGH
FRIDAY WILL BE DRIER...BUT THERE WILL STILL BE A CHANCE OF
AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS EACH DAY.
