HIGH PRESSURE RIDGE STILL DOMINATES NE COLORADO WITH CLEARING
SKIES AND WARMING TEMPERATURES. THE SURFACE LEE TROUGH WILL MOVE
TO THE NE BRINGING INCREASED WINDS TO THE FAR NE CORNER OF THE
PLAINS WITH LIGHTER WINDS NEAR THE FOOTHILLS AND URBAN CORRIDOR
LATER THIS AFTERNOON AND INTO THE EVENING. SKIES WILL CLEAR OUT
OVERNIGHT WITH ANOTHER WARM DAY IN STORE FOR TOMORROW. LIKE TODAY
700 MB TEMPS ARE IN THE +10 TO +11 RANGE WHICH EQUATES TO HIGH
TEMPERATURES OF 80 TO 82 DEGREES. THIS WOULD MEAN ANOTHER POSSIBLE
RECORD BREAKING DAY WITH THE CURRENT HIGH TEMPERATURE RECORD FOR
TOMORROW AT 80 DEGREES.

.LONG TERM...(SATURDAY NIGHT THROUGH FRIDAY)
ISSUED AT 333 PM MDT FRI OCT 24 2014

NO CHANGE IN FORECAST REASONING THIS TIME AROUND...AS MODELS
CONTINUE SHOWING A PROGRESSIVE UPPER TROUGH RACING ACROSS THE
STATE SUNDAY NIGHT AND MONDAY. AHEAD OF THE TROUGH...SOUTHWESTERLY
FLOW ALOFT WILL INCREASE THROUGH THE DAY SUNDAY. THE NAM MODEL
SHOWS ABOUT 20-25 KNOTS OF WIND AT 700 MB...SO THIS MAY MAKE THE
AFTERNOON A BREEZY ONE...ESPECIALLY IN THE FOOTHILLS. TEMPERATURES
ACROSS THE FORECAST AREA WILL BE WARM AGAIN ON SUNDAY...BUT
PROBABLY A FEW DEGREES COOLER THAN THE LEVELS REACHED ON
SATURDAY...DUE TO THE INCREASING HIGH CLOUDS THROUGH THE
AFTERNOON.

BY SUNDAY EVENING...SOME AREAS IN THE MOUNTAINS MAY BEGIN PICKING
UP SHOWERS AS THE TROUGH AXIS APPROACHES. THROUGH THE NIGHT AND
MONDAY MORNING...PRECIPITATION SHOULD SPREAD OUT ONTO THE PLAINS.
RAIN IN THE MOUNTAINS SHOULD CHANGE OVER TO SNOW OVERNIGHT WITH
THE SNOW LEVEL REMAINING ABOVE 8000 FEET. SNOW ACCUMULATIONS UP TO
A FEW INCHES WILL BE POSSIBLE THROUGH MONDAY AFTERNOON. RAINFALL
AMOUNTS SHOULD BE LIGHT ON THE PLAINS. THE UPPER TROUGH WILL BE
MOVING ACROSS THE STATE VERY QUICKLY. MOST OF THE PRECIPITATION
COULD BE OVER BEFORE THE COLD AIR IS ABLE TO MOVE INTO THE STATE.
THE REMAINDER OF MONDAY WILL BE COOL AS THE COLD AIR MOVES INTO
THE STATE. LOWS TUESDAY MORNING COULD BE DOWN AROUND THE FREEZING
LEVEL ACROSS THE PLAINS...ESPECIALLY IF SKIES CLEAR OUT.

THE REMAINDER OF THE WEEK SHOULD BE RETURN TO DRY WEATHER WITH
TEMPERATURES CLIMBING BACK TO SEASONAL NORMALS FOR THE LAST WEEK
OF OCTOBER. STRONG UPPER RIDGING IS EXPECTED TO RE-BUILD ACROSS
THE DESERT SOUTHWEST AND SOUTHERN ROCKIES.
