...DISTURBANCE AND COOL FRONT MOVING THROUGH THIS MORNING...

AN UPPER LEVEL DISTURBANCE WILL TRACK EAST ACROSS THE AREA THIS
MORNING...AND PUSH INTO KANSAS DURING THE AFTERNOON.  AS IT DOES
SO...A COOL FRONT WILL PUSH SOUTH THROUGH THE EASTERN COLORADO
PLAINS.  THE FRONT IS PRETTY WEAK...SO NOT A WHOLE LOT OF WEATHER IS
EXPECTED WITH IT.  HOWEVER...IT MAY TRIGGER A FEW SHOWERS OVER THE
PEAKS AND ACROSS THE PLAINS AS IT SHIFTS SOUTHWARD THIS MORNING.
WILL CARRY SOME LOW PRECIP CHANCES THIS MORNING TO REFLECT THIS
POSSIBILITY.  ANY PRECIP CHANCES SHOULD BE WANING AND SHRINKING BACK
TO THE MOUNTAINS THROUGH THE AFTERNOON...WHERE SOME ISOLATED
ACTIVITY MAY PERSIST INTO THE EARLY EVENING HOURS BEFORE ENDING.

PROBABLY THE MAIN IMPACT OF THE FRONT WILL BE THE COOLING IT WILL
BRING.  HIGHS TODAY OVER THE EAST WILL BE ABOUT 20 DEGREES COOLER
THAN YESTERDAY AND ABOUT 10 DEGREES BELOW AVERAGE.  OVER THE
WEST...HIGHS WILL BE ABOUT 5 DEGREES COOLER THAN YESTERDAY AND
ABOUT 5 DEGREES BELOW AVERAGE.  THIS TREND WILL CARRY ON INTO
TONIGHT WHERE READINGS WILL BE ABOUT 5-10 DEGREES COOLER THAN THIS
MORNING`S LOWS AND ABOUT 3-5 DEGREES COOLER THAN AVERAGE. THE
MOUNTAINS AND HIGH VALLEYS WILL SEE MID 30S TO LOWER 40S WHILE THE
PLAINS RECORD MID 40S TO LOWER 50S.  IT`S STARTING TO FEEL A LITTLE
BIT LIKE SEPTEMBER.

THURSDAY NIGHT...COOLER AIR PUSHES THROUGH THE PLAINS DURING THE
EVENING...WITH WIND GUSTS OVER 30 MPH AND RAPIDLY FALLING
TEMPERATURES. SCATTERED TO NUMEROUS SHOWERS WILL OCCUR. MID LEVEL
TEMPERATURES FORECAST TO FALL TO AROUND 0 DEGREES CELSIUS ACROSS
THE EAST...WHICH WILL ALLOW FOR EITHER SOME SNOWFLAKES TO BE
MIXING IN WITH THE RAINS SHOWERS...OR ALL SNOW HIGHER ELEVATIONS.
THE SUMMIT OF PIKES PEAK MAY PICK UP A COUPLE INCHES OF
ACCUMULATION...WITH A LIGHT COATING POSSIBLE ABOVE 6500 FEET ON
THE COOLER SURFACES. LOW TEMPERATURES WILL REACH THE UPPER 30S TO
LOWER 40S...WITH 20S HIGHEST ELEVATIONS.

50S ACROSS THE EAST...BUT OUT WEST IT SHOULD BE MILD...WITH HIGHS
IN THE 60S AND 70S HIGH VALLEYS. FRIDAY NIGHT...TEMPERATURES
