.PREV DISCUSSION... /ISSUED 402 AM MDT WED MAR 12 2014/

SHORT TERM...BACK TO TRANQUIL WEATHER TODAY WITH RIDGING BOTH
AT THE SURFACE AND ALOFT. AIRMASS IS VERY DRY WITH NARY A CLOUD
IN THE SKY EXPECTED TODAY. ONLY EXCEPTION IS A BIT OF PATCHY EARLY
MORNING FOG AND STRATUS IN PARK COUNTY AS SEEN IN THE 11-3.9 IR
SATELLITE IMAGERY. ELSEWHERE...LOOKS LIKE SUFFICIENT T/TD SPREAD
OR WIND TO KEEP FOG FROM DEVELOPING. NEARLY FULL SUNSHINE WILL ACT
TO BREAK INVERSIONS ON THE PLAINS TODAY SO EXPECT HIGHS MAINLY
NEAR THE 50 DEGREE MARK. PALMER DIVIDE WILL BE A LITTLE COOLER
WITH SNOW COVER. IN THE HIGH MOUNTAIN VALLEYS...TEMPERATURES ARE
STARTING OFF QUITE COLD WITH A COUPLE SPOTS BELOW ZERO. WITH SOME
FRESH SNOW THEY MAY STRUGGLE A BIT TO WARM...SO LOWERED THEM A
COUPLE DEGREES. WINDS WILL BE LIGHT AND VARIABLE MOST AREAS WITH
ONLY THE EASTERN PLAINS SEEING 10-20 MPH WINDS.

MORE CLEAR SKIES AND LIGHT WINDS TONIGHT AS RIDGE DOMINATES. THIS
WILL ALLOW FOR GOOD RADIATION COOLING SO LOWERED MINS A BIT MORE
IN TYPICAL INVERSION AREAS.

LONG TERM...DRY AND WARMER CONDITIONS WILL PREVAIL THURSDAY AND
FRIDAY AS NORTHERN COLORADO LIES UNDER SPLIT FLOW ALOFT TO THE
NORTH OF AN UPPER TROUGH OVER NEW MEXICO. WINDS ALOFT WILL BE WEAK
AND OUT OF THE NORTHWEST. THE NEXT CHANCE OF PRECIPITATION WILL BE
SATURDAY AS A VIGOROUS TROUGH IS FORECAST TO DEVELOP OVER THE
NORTHERN ROCKIES AND SWEEP OVER COLORADO. THE SYSTEM WILL BE
POSITIVELY TILTED AND PROGRESSIVE...MOVING THROUGH THE AREA FAIRLY
QUICKLY. MOUNTAIN AREAS WILL HAVE A FAIR CHANCE OF SEEING SNOW
THROUGH SATURDAY AND SATURDAY EVENING WHILE THE PLAINS WILL SEE
RAIN IN THE AFTERNOON AND THEN RAIN OR SNOW THROUGH THE EVENING.

COOL TEMPERATURES WILL LINGER ON SUNDAY...BUT A STRONG UPPER RIDGE
WILL BE BUILDING OVER THE SOUTHWESTERN U.S. WHICH WILL BRING
WARMER TEMPERATURES TO COLORADO ON MONDAY AND TUESDAY. MODEL
SOLUTIONS THEN DIVERGE FOR THE MIDDLE PART OF NEXT WEEK...MAKING
IT DIFFICULT TO SAY WHETHER NEXT WEDNESDAY IS WET OR DRY.

AVIATION...NEARLY CLOUD FREE SKIES AND LIGHT WINDS WILL PREVAIL
TODAY AND TONIGHT. NORMAL DRAINAGE WINDS AROUND 10 KTS EXPECTED TO
BECOME LIGHT AND VARIABLE AROUND 6 KTS BY 18Z....THEN TRANSITION
BACK TO NORMAL DRAINAGE WINDS AGAIN BY 02Z-03Z.

.BOU WATCHES/WARNINGS/ADVISORIES...
