NWS Denver/Boulder, CO wrote its last area forecast discussion before the first event at Jun 11, 2:30 AM MST, 7 hours 30 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DENVER CO 330 AM MDT WED JUN 11 2008 .SHORT TERM...STRONG COLD FRONT MOVED ACROSS THE PLAINS EARLY THIS MORNING WITH GUSTY WINDS AND MUCH COOLER TEMPERATURES. WINDS WERE STILL GUSTING OVER THE EASTERN PORTIONS OF THE PLAINS WHILE UPSLOPE STRATUS WAS TRYING TO DEVELOP ALONG THE FRONT RANGE...BUT ALSO AT THE SAME TIME ERODING AWAY THANKS TO DRIER LOW LEVEL AIR MOVING IN. MEANWHILE...LARGE SCALE UPWARD Q-G VERTICAL MOTION ASSOCIATED WITH SIGNIFICANT SHORT WAVE WAS MOVING THIS WAY...INCREASING CLOUDS AND PRECIP OVER WESTERN COLORADO. THIS SHORT WAVE LIFT WILL CONTINUE TO PUSH SLOWLY EASTWARD THIS MORNING WITH Q-G VERTICAL MOTION FIELDS FROM THE RUC SHOWING A LOT OF LIFT IN THE 15Z-18Z PERIOD. THIS SHOULD HELP MAKE THE MOST OF THE LIMITED MOISTURE AND HELP GENERATE SOME SHOWERS IN THE MOUNTAINS THIS MORNING AND THEN A FEW SHOWERS/STORMS ACROSS THE PLAINS BY THE NOON HOUR. LOOKS LIKE ANY CONVECTION ON THE PLAINS WILL BE ELEVATED THANKS TO THE COOLER LOW LEVELS. TEMPERATURES WILL BE SHARPLY COOLER...AND HIGHS MAY VERY WELL HINGE ON WHETHER WE GET SOME DOWNSLOPE OFF THE MOUNTAINS BY LATE IN THE DAY. CONSIDERING THE STRONG SUBSIDENCE FOLLOWING THE MID DAY SHORT WAVE...FEEL WE SHOULD BEGIN TO DOWNSLOPE AND DRY DURING THE AFTERNOON WHICH WOULD PROMOTE A LATE DAY HIGH PERHAPS CLOSE TO 70F...AND ALSO SHUT OFF ANY CONVECTION FROM WEST TO EAST ACROSS THE FORECAST AREA. ONLY OTHER CONCERN TODAY WAS FOR RED FLAG CONDITIONS IN PARK COUNTY WHERE FRONT WILL HAVE LEAST IMPACT. HOWEVER...COOLER TEMPERATURES ALOFT MEANS HUMIDITY READINGS WILL HAVE A HARD TIME REACHING CRITERIA SO NO RED FLAGS FOR NOW. MOSTLY CLEAR SKIES...MUCH COOLER TEMPERATURES IN PLACE...AND A DRY ATMOSPHERE WILL PROMOTE A VERY CHILLY NIGHT. EXPECT LOWS TO DIP INTO THE UPPER 30S ACROSS A GOOD CHUNK OF THE PLAINS AND INTO THE 20S IN THE MOUNTAINS. .LONG TERM...WEST TO NORTHWEST FLOW ALOFT WILL BE OVER THE CENTRAL ROCKIES THURSDAY AS AN UPPER LEVEL LOW OVER THE NORTHERN ROCKIES MOVES OFF TO THE NORTHEAST. WILL SEE A WEAK WAVE EMBEDDED IN THIS FLOW THURSDAY AFTERNOON. WILL KEEP 10 POPS IN THE FORECAST FOR THIS. WOULD BE SURPRISED TO SEE ANYTHING MORE THAN A FEW LIGHT SHOWERS THURSDAY AFTERNOON AND EVENING. AIRMASS WILL BE DRY WITH DEW POINTS IN THE 20S AND 30S AND WINDS WILL BE DOWNSLOPING ACROSS THE PLAINS. WARMING AND CONTINUED DRY CONDITIONS IS IN STORE FOR FRIDAY AND SATURDAY WITH RIDGING IN THE WESTERLY FLOW ALOFT. COOLED TEMPERATURES FOR SUNDAY AND MONDAY WITH BOTH THE GFS AND ECMWF SHOWING A COLD FRONT PUSHING THROUGH. DONT EXPECT ANY PRECIPITATION AS THE FRONT PASSING THROUGH DUE TO THE DRY AIRMASS IN PLACE. NORTH WINDS BEHIND THE FRONT SUNDAY WILL VEER TO THE SOUTHEAST MONDAY...INCREASING THE LOW LEVEL MOISTURE ACROSS THE PLAINS. WILL LEAVE 10 POPS IN THE FORECAST FOR THIS ON MONDAY AFTERNOON AND EVENING. && .AVIATION...UPSLOPE BEHIND COLD FRONT HAS RESULTED IN SOME MVFR CIGS ALONG THE FRONT RANGE. HOWEVER...DRIER AIR WORKING IN FROM THE NORTH WAS ALSO LIFTING CONDENSATION LEVELS AND LIMITING CLOUD COVERAGE. WILL HAVE TO MONITOR POTENTIAL FOR OCCASIONAL MVFR CIGS BUT AT THE PRESENT TIME LOOKS LIKE MOST CEILINGS WILL REMAIN VFR THROUGH TODAY. THREAT OF SHOWERS/ISOLATED STORMS IS LIMITED ENOUGH TO WARRANT VCSH IN TAFS IN THE 17Z-22Z TIME FRAME. && .BOU WATCHES/WARNINGS/ADVISORIES...NONE. && BARJENBRUCH/MEIER

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
