NWS Denver/Boulder, CO wrote its last area forecast discussion before the first event at Jun 21, 9:03 AM MST, 4 hours 33 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DENVER/BOULDER CO 1003 AM MDT SAT JUN 21 2014 .UPDATE... ISSUED AT 936 AM MDT SAT JUN 21 2014 MAIN CHANGES TO FORECAST WAS FOR MORE CLOUD COVER THIS MORNING AND ADDED THUNDERSTORM STORM CHANCES FURTHER WEST INTO LINCOLN AND WASHINGTON COUNTIES THIS AM. THERE IS STILL A NARROW BAND OF SHOWERS ACROSS NORTHERN LINCOLN AND SOUTHEAST WASHINGTON COUNTIES ALONG WEAK CONVERGENCE AND SURFACE LOW ACROSS EAST CENTRAL COLORADO. THESE SHOWERS HAVE RESULTED IN A WEAK OUTFLOW BOUNDARY MOVING WEST INTO ELBERT AND SOUTHEAST ARAPAHOE COUNTIES THIS MORNING AND MAY AID TO FOCUS ADDITIONAL STORMS THIS AFTERNOON. OVERALL A BETTER CHANCE FOR STORMS TODAY AS MOISTURE VALUES HAVE INCREASED. INTEGRATED PW VALUES FROM GPS INDICATED ABOUT A QUARTER INCH INCREASE IN PAST 18 HOURS. SHORT RANGE MODEL GUIDANCE INDICATES BEST CHANCE FOR STORMS WILL BE OVER THE PALMER DIVIDE AND OVER THE FAR NORTHEAST CORNER THIS AFTERNOON AND EVENING. THIS LOOKS REASONABLE GIVEN HIGHER LOW LEVEL MOISTURE WITH DEWPOINTS IN THE MID 50S TO LOWER 60S. COULD BE A FEW SEVERE STORMS GIVEN SURFACE BASED CAPE VALUES RANGING FROM 1000-2000J/KG. FURTHER WEST TOWARDS THE FRONT RANGE EXPECT MORE HIGH BASED STORMS WITH GUSTY WINDS THE MAIN THREAT AS LOW LEVELS MIX OUT. SEVERAL WEAK DISTURBANCES ALOFT ACROSS THE GREAT BASIN WILL HELP AID TO THE INCREASED SHOWER ACTIVITY TODAY. && .SHORT TERM...(TODAY THROUGH TONIGHT ) ISSUED AT 511 AM MDT SAT JUN 21 2014 A WEAK AND NOT VERY WELL DEFINED SHORTWAVE WILL MOVE OVER COLORADO IN LIGHT WESTERLY FLOW ALOFT TODAY. THIS WILL BRING MORE HIGH CLOUD COVER TODAY. THERE IS ACTUALLY A LITTLE WARMING STILL THROUGHOUT THE LOWER TROPOSPHERE...THOUGH CLOUD COVER MAY KEEP THE SURFACE TEMPERATURES FROM WARMING MUCH. THIS WILL BE OFFSET BY THE CONTINUED GRADUAL LOW LEVEL MOISTENING. WELL DEFINED MOISTURE POOL OVER THE NORTHEAST CORNER HAS BEEN MIXED A BIT BY THE OVERNIGHT CONVECTION...BUT WITH THE LIGHT WIND PATTERN STAYING THE SAME THE MOISTURE FIELD WILL BE WORKING BACK TOWARD THE SAME PATTERN WITH THE BEST MOISTURE AND INSTABILITY OVER THE NORTHEAST CORNER. WITH LIGHT EAST WINDS AND NOT MUCH WIND ALOFT THE MODELS OVERDID THE MIXING OUT OF THE MOISTURE OVER MOST OF OUR AREA YESTERDAY...THIS MAY BE THE CASE AGAIN TODAY. WITH DEW POINTS AROUND 40 IN DENVER AND 50 IN THE NORTHEAST CORNER AFTERNOON CAPES WILL BE AROUND 1000 J/KG NEAR THE MOUNTAINS...AND AROUND 2000 J/KG IN THE CORNER. LACK OF WIND WILL CONTINUE TO LIMIT THE SEVERE POTENTIAL...EXPECT PULSY/MULTICELL UPRIGHT CONVECTION AGAIN...ENOUGH CAPE FOR SOME TO BE NEAR SEVERE IN THE BETTER MOISTURE. OVER THE MOUNTAINS WHERE IT IS DRIER CONVECTION MAY NOT BE DEEP/STRONG ENOUGH FOR MUCH PRECIPITATION. ONLY MINOR CHANGES TO TODAYS FORECAST THEN...MAINLY MORE CLOUD COVER AND TWEAKING THE POPS TO FOCUS ON THE SAME AREAS WE HAVE HAD CONVECTION THE LAST FEW NIGHTS...STARTING EAST AND SOUTH OF DENVER AND SPREADING TOWARD THE NORTHEAST CORNER. .LONG TERM...(SUNDAY THROUGH FRIDAY) ISSUED AT 511 AM MDT SAT JUN 21 2014 ON SUNDAY...A SYSTEM PASSING TO THE NORTH OF COLORADO WILL PUSH A COLD FRONT INTO THE NORTHEAST PLAINS AND URBAN CORRIDOR IN THE MORNING. THE AIRMASS WILL BECOME INCREASING MOIST FOLLOWING THE PASSAGE OF THE FRONT...WITH INCREASING INSTABILITY DEVELOPING AFTER 21Z. INTERACTIVE SOUNDINGS GENERALLY PRODUCE CAPES OF 1000-1200 J/KG AT KDEN AND KAKO...WITH SFC BASED CAPES AROUND 2500 J/KG AT KLIC. THE BEST COMBINATION OF SHEAR AND INSTABILITY WILL BE ALONG SOUTH OF THE APPROACHING COLD FRONT. GOOD DIRECTIONAL SHEAR ESPECIALLY IN THE LOWER LEVELS...SO SUSPECT LARGE HAIL...DAMAGING WINDS AND ISOLATED TORNADOES POSSIBLE. ESPECIALLY TO THE SOUTH AND SOUTHEAST OF DENVER. PW VALUES INCREASE AS WELL SO HEAVY RAIN POTENTIAL WILL INCREASE BUT STORM MOTIONS AROUND 20 KTS MAY OFFSET THIS. STORMS MAY CONTINUE OVERNIGHT SUNDAY NIGHT ACROSS THE FAR EASTERN PLAINS. ON MONDAY...THE FRONTAL BOUNDARY WILL SETTLE ALONG THE FRONT RANGE AND PALMER DIVIDE. WEAK EAST/SELY WINDS AT THE SFC WILL LIKELY PRODUCE A WEAK DENVER CYCLONE. PLENTY OF LOW LEVEL MOISTURE AROUND MONDAY MORNING TO MENTION SOME PATCHY FOG. IT WILL REMAIN RELATIVELY COOL BUT IN THE AFTN...CAPES INCREASE IN THE 700-1200 J/KG RANGE...WITH THE GREATEST POTENTIAL TO THE SOUTH AND SOUTHEAST OF DENVER. SIMILAR CONDITIONS WILL CARRYOVER INTO TUESDAY. WEDNESDAY THROUGH FRIDAY...AN UPPER LEVEL RIDGE WILL BUILD IN FROM THE SOUTH AND WEST. THE LOWER LEVELS WILL DRY OUT WITH THE MOISTURE FOCUS SHIFTING FURTHER EAST. BEST CHC OF STORMS FOR THE LATTER HALF OF THE WEEK WILL BE OVER THE FAR NORTHEAST PLAINS...WHERE THE BEST LOW LEVEL MOISTURE WILL BE. ELSEWHERE...IT WILL BE DRY AND HOTTER WITH JUST ISOLD HIGH BASED TSTMS POSSIBLE IN THE AFTN/EVNG MAINLY OVER THE HIGHER TERRAIN. && .AVIATION...(FOR THE TAFS THROUGH 18Z SUNDAY MORNING) ISSUED AT 936 AM MDT SAT JUN 21 2014 ONLY MINOR CHANGES TO UPCOMING 18Z TAFS. KAPA AND KDEN WILL LIKELY BE ON THE EDGE OF THE STRONGER STORMS WITH STORM LIKELY TO FORM ON OUTFLOW BOUNDARY MOVING WEST INTO EASTERN ADAMS AND ARAPAHOE COUNTIES. FOR NOW WILL GO WITH TEMPO GROUPS FOR WIND GUSTS AND THUNDER AT APA AND DEN. BJC MAY BE TOO DRY SO WILL REMOVE TS FOR NOW AND MONITOR ANY STORMS COMING OFF THE MOUNTAINS. && .BOU WATCHES/WARNINGS/ADVISORIES... NONE. && UPDATE...ENTREKIN SHORT TERM...GIMMESTAD LONG TERM...COOPER AVIATION...ENTREKIN
