NATIONAL WEATHER SERVICE DENVER/BOULDER CO
250 PM MDT THU OCT 2 2014

.SHORT TERM...(THIS EVENING THROUGH FRIDAY)
ISSUED AT 250 PM MDT THU OCT 2 2014

THE MAIN FEATURE FOR THIS PERIOD IS THE UPPER LEVEL TROUGH AND
ASSOCIATED COLD FRONT THAT WILL SWEEP BY THE NE PORTIONS OF THE
STATE LATE TONIGHT. WINDS WILL SWITCH TO A MORE NORTH TO
NORTHWEST DIRECTION WITH THE ONSET OF THE COLD FRONT AROUND
MIDNIGHT. WITH THIS WIND CHANGE SIGNIFICANTLY COOLER AIR WILL MOVE
IN BRINGING TEMPS INTO THE LOWER TO MID 30S ACROSS THE CWA
OVERNIGHT. THERE IS A SLIGHT CHANCE OF SHOWERS WITH THE
POSSIBILITY OF SNOW SHOWERS AFTER MIDNIGHT MAINLY OVER THE NE AND
CO BORDERS. WITH THE QUICK SHOT OF NORTHEAST FLOW OVER THE PLAINS
SOME STRATUS WILL MOVE IN OVERNIGHT BUT WILL MOVE OUT QUICKLY
BEFORE SUNRISE WITH A DRIER AND MORE STABLE AIRMASS MOVING IN
BEHIND THE FRONT.

ISSUED A FROST ADVISORY FOR THE EARLY MORNING ON FRIDAY TO
CORRESPOND WITH DECREASING CLOUD COVER AND WINDS THAT WILL ALLOW
TEMPERATURES TO DIP BELOW 35 IN MOST AREAS AND COULD BECOME A
HAZARD TO SENSITIVE PLANTS.

ONLY GETTING INTO THE UPPER 50S AND LOWER 60S WITH PARTLY CLOUDY
TO SUNNY SKIES.

NORTHEAST COLORADO WILL BE UNDER MODERATE TO STRONG NORTHWESTERLY
FLOW ALOFT THROUGH THE FORECAST PERIOD. THERE MAY BE SOME MID AND
HIGH CLOUDINESS AT TIMES THROUGH THE WEEKEND AS SOME MOISTURE
RIDES OVER THE RIDGE AXIS AT TIMES ALONG THE WEST COAST. WEATHER
