THE LEESIDE MOUNTAIN WAVE CONTINUES TO RELAX AND THE GJT-DEN
1500M PRESSURE GRADIENT CONTINUES TO WEAKEN AT THIS HOUR. AS A
RESULT WIND SPEEDS HAVE STEADILY DECREASED OVER AND ALONG THE

DOWNSLOPE WIND PATTERN WITH SPEEDS IN THE 5-12KT RANGE. WITH
FLATTENING OF THE MTN WAVE AND DRYING AT MID-LEVELS...SHOULD SEE
THE LAST OF THE MTN WAVE CLOUD BAND SHIFTING SOUTHEAST OF THE

&&

.SHORT TERM...(THIS EVENING THROUGH THURSDAY)
ISSUED AT 1202 PM MST WED FEB 10 2016

JUST A FEW SUBTLE CHANGES TO THE WEATHER OVER THE NEXT 24 HOURS.
HIGH LEVEL MOISTURE WILL INCREASE...PRODUCING MORE WAVE CLOUDS
THIS EVENING AND THEN MORE WIDESPREAD HIGH CLOUDINESS BY THURSDAY.
EXPECTING A LITTLE INCREASE IN MOUNTAIN/FOOTHILL WINDS IN THE LATE
AFTERNOON AND EARLY EVENING...THEN THE FLOW ALOFT TICKS UP A BIT
FOR THURSDAY BUT THE TEMPERATURE STRUCTURE FOR THE MOUNTAIN WAVE
IS NOT AS GOOD. SO OVERALL ONLY MINOR FLUCTUATIONS TO THE WINDS
WITH 30-40 MPH GUSTS IN THE WINDIER FOOTHILLS AREAS AT TIMES.
TEMPERATURE PATTERN SHOULD ALSO BE FAIRLY STEADY THOUGH WITH THE
WEST WINDS THERE SHOULD BE CONTINUED GRADUAL EROSION AROUND THE
EDGES OF THE COLD POOLS. THERE IS SLIGHT LOW LEVEL COOLING ON
THURSDAY IN ADDITION TO MORE CLOUDS...SO ABOUT 5 DEGREES OF
COOLING IN MOST AREAS STILL LOOKS GOOD.

.LONG TERM...(THURSDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 1202 PM MST WED FEB 10 2016

A MODERATE TO STRONG NORTHWESTERLY FLOW ALOFT WILL BE OVER
COLORADO THURSDAY NIGHT THROUGH SATURDAY. THE RIDGE WILL FLATTEN
AND SHIFT TO THE EAST LATE SATURDAY AND SATURDAY NIGHT AS AN
EMBEDDED SHORT WAVE TROUGH BRUSHES ACROSS THE STATE. THIS WILL
BRING A CHANCE OF SNOW TO THE MOUNTAIN WEST OF THE DIVIDE...WITH
SOME GUSTY WINDS IN AND NEAR THE FOOTHILLS. IT WILL BE A LITTLE
COOLER ON SUNDAY RELATIVE THE OTHER DAYS IN THE FORECAST
PERIOD...BUT OVERALL TEMPERATURES WILL BE ABOVE NORMAL. THERE WILL
BE A SLIGHT CHANCE OF PCPN OVER THE NORTHEAST PLAINS SUNDAY NIGHT
BUT DRY OTHERWISE. A STRONGER NORTHWESTERLY FLOW ALOFT WILL
DEVELOP SUNDAY NIGHT AND INTO MONDAY...THEN DRIER AND WARMER
TUESDAY AND WEDNESDAY WITH HIGHS AROUND 60...AS A BROAD RIDGE OF
HIGH PRESSURE SPREADS ACROSS THE WEST.

&&

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z THURSDAY NIGHT)
ISSUED AT 922 PM MST WED FEB 10 2016

VFR CONDITIONS ANTICIPATED FOR THE REMAINDER OF THE NIGHT. A
WEAKENING OF THE CROSS-STATE PRESSURE GRADIENT PRESSURE AND
FLATTENING OF THE MTN WAVE WILL CAUSE WEST-NORTHWEST WINDS IN THE
METRO AREA TO GRADUALLY ASSUME A MORE TYPICAL DRAINAGE PATTERN
WITHIN THE NEXT COUPLE OF HOURS. SPEEDS FOR THE MOST PART SHOULD
BE UNDER 12 KTS.
