AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER/BOULDER CO
343 AM MDT WED JUN 10 2015

.SHORT TERM...(TODAY THROUGH TONIGHT )
ISSUED AT 343 AM MDT WED JUN 10 2015

AIRMASS WILL BE VERY MOIST TODAY AS THE REMNANTS OF HURRICANE
BLANCA MOVE OVER COLORADO. PRECIPITABLE WATER VALUES WILL CLIMB
ABOVE AN INCH TODAY...RECORD LEVELS FOR THIS TIME OF YEAR. THE
RAP IS SHOWING 1.25 INCHES WHICH IS CLOSE TO THE JUNE RECORD OF
1.29. THIS MOISTURE IS CURRENTLY PRODUCING CLOUDY SKIES ACROSS
COLORADO AND THE FOUR CORNERS AREA ALONG WITH SHOWERS AND
ISOLATED THUNDERSTORMS. EXPECT THESE SHOWERS AND ISOLATED STORMS
TO CONTINUE THIS MORNING. THUNDERSTORMS WILL INCREASE THIS
AFTERNOON AS THE AIRMASS BECOMES UNSTABLE.

WATER VAPOR SATELLITE IMAGERY SHOWING A SHORT WAVE TROUGH OVER
UTAH. MODELS INDICATE THE WAVE WILL LIFT EAST-NORTHEAST ACROSS
THE AREA TODAY. THE BEST LIFT ASSOCIATED WITH IT WILL BE OVER
NORTHERN PARTS OF COLORADO. EXPECT THIS TO TRIGGER SCATTERED
THUNDERSTORMS THIS AFTERNOON.

THERE WILL BE A CHANCE FOR SEVERE THUNDERSTORMS TODAY. BEST
CHANCE FOR SEVERE STORMS WILL BE OVER THE NORTHEAST CORNER OF THE
STATE WHERE TEMPERATURES ARE EXPECT TO REACH THE LOWER 80S. THIS
WILL RESULT IN CAPES OF 1000-2000 J/KG. FOR THE FRONT RANGE AND
NEAR BY PLAINS...THE SEVERE THREAT WILL DEPEND ON THE AMOUNT OF
HEATING. IF TEMPERATURES CAN REACH THE UPPER 70S WOULD EXPECT
CAPES OF AROUND 1000 J/KG. MODELS ARE ALL OVER ON THE AMOUNT OF
INSTABILITY TODAY. THE GFS AND NAM SHOW CAPES AROUND 500 J/KG
LATE THIS AFTERNOON. HOWEVER...THE RAP HAS CAPES REACHING 2000
J/KG IN THE DENVER AREA. WOULD EXPECT CAPES SOMEWHERE IN BETWEEN.
THOUGH IF CLOUD COVER REMAINS THICK ALL DAY CAPES COULD BE ON THE
LOWER END AND THE AIRMASS COULD BE SOMEWHAT CAPPED. LOW LEVEL
SHEAR WILL BE WEAK...SO THE TORNADO THREAT WILL BE VERY LOW.

STORMS WILL DECREASE THIS EVENING AS THE WAVE SHIFTS EAST OF THE
AREA. FROM MID EVENING THROUGH TONIGHT...SUBSIDENCE WILL BE OVER
THE AREA BEHIND THE EXITING WAVE. AIRMASS WILL REMAIN MOIST WITH
PRECIPITABLE WATER VALUES AROUND AN INCH. WILL KEEP LOW POPS IN
THE FORECAST THROUGH THE NIGHT AS THERE MAY BE A FEW LINGERING
SHOWERS AROUND.

.LONG TERM...(THURSDAY THROUGH TUESDAY)
ISSUED AT 343 AM MDT WED JUN 10 2015

THURSDAY...THERE WILL BE A WEAK SHORT WAVE RIDGE PRESENT IN THE
MORNING AS ONE SYSTEM EXITS TO THE EAST OVER THE NEBRASKA
PANHANDLE AND THE NEXT SYSTEM OVER THE GREAT BASIN APPROACHES FM
THE SOUTHWEST. THE MDLS BRING A COLD FRONT INTO THE FRONT RANGE IN
THE MORNING...15-18Z...WITH NELY UPSLOPE WINDS DEVELOPING BY LATE
AFTN BLO 700 MB. THE AMS WILL BE VERY MOIST WITH PW VALUES IN
EXCESS OF ONE INCH. FORECAST CAPES ON THE SOUNDINGS INCREASE BY
THE AFTN...THE GFS BUFFER SOUNDINGS YIELD VALUES OF 500-700 J/KG
BY 21Z WHILE THE NAM12 SOUNDINGS GENERATE AROUND 1100 J/KG. SOME
DIRECTIONAL SHEAR AS WELL...BEST CHC OF SEVERE WOULD STILL APPEAR
TO BE OVER THE PALMER DIVIDE THURSDAY AFTERNOON. THURSDAY NIGHT
INTO FRIDAY...THE MDLS GENERATE PRETTY GENEROUS QPF AMOUNTS ALONG
THE FRONT RANGE/PALMER DIVIDE. CERTAINLY ENOUGH TO ELEVATE THE
CONCERNS FOR FLOODING/FLASH FLOODING. THE SOUNDINGS GENERATE THE
DEEPEST EASTERLY UPSLOPE FM 06Z-18Z THURSDAY NIGHT/FRIDAY MORNING.
LOCALLY HEAVY RAIN PRODUCING THUNDERSTORMS THURSDAY AFTN/THURSDAY
NIGHT...MAY TRANSITION TO MORE OF A STEADY LGT TO MODERATE
RAINFALL BY FRIDAY MORNING. LIKELY POPS LOOK LIKE A GOOD
BET...ESPECIALLY IN AND NEAR THE FOOTHILLS. THE UPPER TROUGH
APPEARS TO STALL OVER COLORADO AT THAT TIME...SLOWLY MAKING ITS
WAY EAST INTO KANSAS SATURDAY MORNING. AS A RESULT...MAY BUMP THE
POPS UP ON FRIDAY/FRIDAY NIGHT AS WELL. OVER THE WEEKEND...IT MAY
NOT BE AS WET BUT STILL UNSETTLED...WITH SOME MOISTURE AND A WEAK
TROUGH SHIFTING ACROSS SOUTHERN COLORADO. BY TUESDAY...FINALLY
APPEAR TO BE A DRIER WEST/SOUTHWESTERLY FLOW IN THE MID AND UPPER
LEVELS...SLGT CHC OF AFTN/EVNG THUNDERSTORMS WILL SUFFICE FOR THAT
TIME.

.AVIATION...(FOR THE TAFS THROUGH 12Z THURSDAY MORNING)
ISSUED AT 343 AM MDT WED JUN 10 2015

THERE WILL BE A GOOD CHANCE FOR THUNDERSTORMS TODAY...FROM 18Z TO
00Z. WILL HAVE A TEMPO FOR TSRA IN THE TAFS FOR THIS. VERY HEAVY
RAIN...SMALL HAIL AND OUTFLOW WINDS TO 40 KNOTS WILL BE THE MAIN
THREATS WITH THE STORMS. SKIES WILL BE MOSTLY CLOUDY TODAY WITH
PARTIAL CLEARING EXPECTED TONIGHT. OUTSIDE OF THUNDERSTORMS...
CEILINGS ARE EXPECTED TO REMAIN ABOVE 6000 FEET. SOUTHERLY WINDS
TO 20 KNOTS WILL BECOME LIGHT AND VARIABLE BY 15Z.

&&

.HYDROLOGY...
ISSUED AT 343 AM MDT WED JUN 10 2015

ANY STORM THAT FORMS TODAY WILL BE CAPABLE OF PRODUCING HEAVY
RAIN DUE TO THE VERY MOIST AIRMASS. AN INCH IN 30 MINUTES OR LESS
WILL BE POSSIBLE WITH THE STRONG STORMS. THE STORMS SHOULD BE
MOVING 15 TO 20 MPH...SO NOT EXPECTING STATIONARY STORMS. THE
THREAT FOR HEAVY RAIN WILL END EARLY THIS EVENING AS THE
THUNDERSTORMS MOVE OFF TO THE EAST.

A VERY MOIST AIRMASS WILL REMAIN OVER THE STATE THURSDAY
AFTERNOON THROUGH FRIDAY NIGHT. A COLD FRONT WILL PRODUCE UPSLOPE
FLOW THURSDAY WITH WIDESPREAD SHOWERS AND SLOW MOVING
THUNDERSTORMS OVER THE PLAINS AND INTO THE FOOTHILLS. RAINFALL
AMOUNTS THURSDAY THROUGH FRIDAY ARE EXPECTED TO BE AROUND 1 TO 2
INCHES...WITH HIGHER AMOUNTS OVER THE UPSLOPE ENHANCED FOOTHILLS
AND PALMER DIVIDE. SATURATED SOILS WILL INHIBIT MUCH SOAKING AND
COULD CAUSE FLOODING ISSUES QUICKLY. THIS WILL CAUSE RIVERS AND
STREAM LEVELS TO RISE AND THE MAIN RIVERS DOWNSTREAM...NAMELY THE
SOUTH PLATTE...RESULTING IN ANOTHER SURGE OF WATER TO PUSH DOWN
OVER THE WEEKEND. ROCK/MUDSLIDES WL BE AN ISSUE AS WELL IN THE
FOOTHILLS.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTHEAST AND NORTH CENTRAL
COLORADO.

.DAY ONE...TODAY AND TONIGHT

SCATTERED THUNDERSTORMS ARE EXPECTED THIS AFTERNOON AND EARLY
EVENING. A FEW STORMS COULD BECOME SEVERE WITH GOLF BALL SIZE HAIL
AND DAMAGING WINDS. A BRIEF TORNADO OR TWO CAN'T BE RULED OUT. THE
BEST CHANCE FOR SEVERE THUNDERSTORMS WILL BE EAST OF A LINE FROM
FORT MORGAN TO LIMON.

HEAVY RAIN WILL ALSO BE POSSIBLE WITH THE THUNDERSTORMS. AN INCH
OF RAIN IN 20 TO 30 MINUTES WILL BE POSSIBLE WITH THE STRONGER
STORMS WHICH COULD CAUSE FLOODING OF LOW LYING AREAS.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

ON THURSDAY...A COLD FRONT WILL PUSH INTO NORTHEASTERN COLORADO
AS AN ABUNDANCE OF MOISTURE IS IN PLACE OVER THE STATE. SHOWERS
AND THUNDERSTORMS WILL BE LIKELY ACROSS THE AREA. SOME OF THE
STORMS COULD BECOME SEVERE IN THE AFTERNOON AND EVENING...
ESPECIALLY OVER THE PALMER DIVIDE. THOSE STORMS COULD PRODUCE
LARGE HAIL AND POSSIBLY TORNADOES. THE BIGGER THREAT WILL BE
POSSIBLE FLOODING ALONG THE FRONT RANGE FOOTHILLS AND PALMER
DIVIDE THURSDAY NIGHT DUE TO HEAVY RAIN WITH SLOW MOVING STORMS.
THE INCREASED CHANCE OF RAIN WILL LAST INTO FRIDAY BUT WITH LESS
STORM COVERAGE.

IT WILL BE A LITTLE DRIER BUT REMAIN UNSETTLED OVER THE WEEKEND
...WITH AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS. THE DRIER
PATTERN WILL CONTINUE MONDAY INTO TUESDAY OF NEXT WEEK.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY BE NEEDED THIS AFTERNOON.
