CURRENTLY...STRONG UPPER TROUGH LIFTING OUT OF THE GREAT BASIN INTO
NORTHERN COLORADO THIS AFTERNOON...WITH DEEP LEE TROUGH OVER THE
EASTERN PLAINS. WINDS HAVE CRANKED UP MOST AREAS...WITH WIDESPREAD
30-40 KNOT GUSTS AS OF 20Z. FEW TSRA TRYING TO MIGRATE NORTHWARD OUT
OF NM THIS AFTERNOON...BUT MOIST INSTABILITY IS LACKING...WITH
HIGHER CAPES LIMITED TO AREAS ALONG THE RATON MESA AND THE FAR EAST
ALONG THE KS BORDER. SOME POTENTIAL FOR STORMS TO PRODUCE SEVERE
WINDS SOUTHEAST OF A KTAD TO KLAA THIS AFTERNOON...BEST CHANCE WOULD
BE OVER BACA COUNTY WERE HIGHER CAPE AIR OVER THE TX/OK PANHANDLES

TONIGHT...MAIN CONCERN IS THE WIND AND WHAT TO DO WITH THE CURRENT
HIGH WIND WATCH. CROSS SECTIONS OFF BOTH THE GFS AND NAM SUGGEST
60-70 KNOT WINDS BELOW 700 MB OVER THE EASTERN MOUNTAINS AFTER
03Z...WITH HIGHEST SPEEDS IN THE 06Z-12Z TIME FRAME AS FLOW BECOMES
MORE WLY. POTENTIAL FOR MOUNTAIN WAVE ENHANCEMENT LOOKS LOW GIVEN
STRONG SPEED SHEAR AND WEAK STABLE LAYER...WITH LOCALLY FAVORED GAP
FLOW THE LIKELY MECHANISM TO PRODUCE DAMAGING WINDS. THESE TYPE OF
EVENTS ARE DIFFICULT TO FORECAST...AS STRONG WINDS AT MOUNTAIN TOP
LEVEL ALOFT DONT ALWAYS MAKE IT TO THE SURFACE. STILL...WITH
SUBSIDENCE BEHIND THE DEPARTING UPPER TROUGH AIDING IN DOWNWARD
MOMENTUM TRANSPORT...SUSPECT FAVORED AREAS OF THE SANGRES (WEST OF
WESTCLIFFE) AND THE RAMPART RANGE IN TELLER COUNT WILL SEE LOCALIZED
DAMAGING WINDS. GAP FLOW THROUGH LA VETA PASS AND STRONG WINDS WEST
OF WALSENBURG ALSO A POSSIBILITY. WILL TRIM OFF THE LESS FAVORED WET
MOUNTAINS AND ARKANSAS VALLEY FROM THE CURRENT WATCH...AND UPGRADE
THE REMAINING PORTION TO A WARNING FOR THE OVERNIGHT. BROADBRUSH OF
SCATTED POPS OVERNIGHT LOOKS FINE...THOUGH RAINFALL AMOUNTS WILL BE
LIGHT AND SPOTTY.

SUNDAY...WINDY IN THE MORNING...ESPECIALLY HIGHER EXPOSED TERRAIN
OVER THE EASTERN MOUNTAINS. BY AFTERNOON...SHORT WAVE RIDGE BUILDS
ACROSS THE STATE WITH A QUICK DROP OFF IN WIND SPEEDS AFTER 18Z. 700
MB TEMPS SHOW A QUICK REBOUND BY LATE AFTERNOON...THUS MAX TEMPS
WILL ONLY COOL 5-10F VERSUS SATURDAY. MADE VERY FEW CHANGES TO
SUNDAY GRIDS...EXCEPT FOR EARLY MORNING WINDS OVER THE MOUNTAINS.
