.SHORT TERM...(THIS EVENING THROUGH THURSDAY)
ISSUED AT 343 PM MDT WED JUN 10 2015

...THUNDERSTORMS THIS EVENING WITH LOCALLY HEAVY RAIN AND
SOME SEVERE WEATHER THREAT...

...FLOOD AND SEVERE THREAT INCREASING TOMORROW AFTERNOON...

QUICK DISCUSSION. VERY BUSY.  LINE OF STORMS COMING THROUGH LATE
THIS AFTERNOON ASSOCIATED WITH REMNANTS OF BLANCA DEPRESSION PASSING
THROUGH.  LOCALLY HEAVY RAIN EXPECTED...BUT QUICK MOVING WHICH
SHOULD REDUCE THE OVERALL FLASH FLOOD THREAT THIS EVENING.  OTHER
THREATS WITH LINE INCLUDE WIND GUSTS TO AROUND 50 MPH...AND
HAIL...MOSTLY SMALL...BUT UP TO 1" DIAMETER POSSIBLE.  TOR THREAT IS
LOW AS SHEAR/LOW LEVEL WINDS ARE NOT LOOKING THE BEST FOR STORM
SCALE ROTATION.  SOME THREAT OF THIS...HOWEVER...OVER NORTHERN EL
PASO COUNTY...AND THE FAR EASTERN PLAINS...NEARING THE KANSAS BORDER
WHERE LOW LEVELS WINDS ARE MORE SUPPORTIVE OF LOW LEVEL STORM
ROTATION.  AFTER THE LINE MOVES THROUGH THIS EVENING...SHOULD SEE
MUCH LESS ACTIVITY OVERNIGHT...MUCH MORE SPOTTY IN NATURE...RIGHT ON
INTO THURSDAY MORNING.

THEN...THURSDAY AFTERNOON...SHOWER AND STORM ACTIVITY WILL BE
RAMPING UP AGAIN.  A LARGE LOW PRESSURE SYSTEM WILL MOVE NEAR
THE FOUR CORNERS REGION...WHILE FRONTOGENESIS OCCURS ALONG THE
PALMER DIVIDE AND EL PASO COUNTY.  THIS WILL LEAD TO WIDESPREAD
SHOWER AND THUNDERSTORM DEVELOPMENT DURING THE AFTERNOON ESPECIALLY
OVER THE MOUNTAINS...AND LATE IN THE AFTERNOON OVER EL PASO AND
TELLER COUNTIES. THUS...THE FLASH FLOOD WATCH BEGINNING AT 3 PM.
HEAVY RAIN WILL BE POSSIBLE ALONG WITH SOME SEVERE STORMS TOMORROW
AFTERNOON.  THIS WILL BE JUST THE START OF THE RAIN.  MUCH MORE TO
COME.  SEE LONG TERM DISCUSSION FOR DETAILS. LW

.LONG TERM...(THURSDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 343 PM MDT WED JUN 10 2015

...HIGH IMPACT HEAVY RAIN THURSDAY NIGHT THROUGH FRIDAY AFTERNOON...

THURSDAY NIGHT-FRIDAY...MODELS REMAIN IN GOOD AGREEMENT OF
WIDESPREAD HEAVY RAINFALL ACROSS EASTERN COLORADO THURSDAY NIGHT AND
FRIDAY...AS A COLD FRONT MOVING ACROSS THE EASTERN PLAINS LATE
THURSDAY AFTERNOON AND EVENING INTERACTS WITH A BROAD UPPER TROUGH
SLOWLY MOVING ACROSS THE FOUR CORNERS AND ROCKIES. MODELS CONTINUE
TO INDICATE AMPLE AVAILABLE MOISTURE WITH PWATS RUNNING BETWEEN 0.75
AND 1 INCH...150-200 PERCENT ABOVE SEASONAL LEVELS. THIS...COMBINED
WITH BROAD UVV AHEAD OF SAID TROUGH AND WEAK THOUGH RELATIVELY DEEP
UPSLOPE FLOW BEHIND SAID FRONT...SHOULD LEAD TO WIDESPREAD MODERATE
TO HEAVY RAINFALL THROUGH THE PERIOD. MODEL RUNS DIFFER WITH THE QPF
BULLSEYE (1 TO 3 INCHES) ACROSS THE EASTERN MOUNTAINS AND PLAINS...THOUGH
CONCEPTUALLY SHOULD SEE THE HEAVIEST RAINS ALONG WEST OF THE I-25
CORRIDOR...WHERE LOW LEVEL UPSLOPE FLOW WILL KEEP STORMS TRAINING
AND SOUNDINGS SUGGEST WARM RAIN PROCESSES DEVELOPING OVERNIGHT.

THIS CONTINUES TO LOOK TO BE A VERY HIGH IMPACT EVENT FOR SOUTH
CENTRAL AND SOUTHEASTERN COLORADO...WITH WIDESPREAD HEAVY RAIN ALONG
WITH POSSIBLE MODERATE TO HEAVY SNOWFALL...MAINLY ON TOP OF THE
HIGHEST PEAKS...AOA 12K FT...OF THE CENTRAL AND EASTERN MTS. A
FLASH FLOOD WATCH HAS ALREADY BEEN ISSUED FOR THIS PERIOD...DUE TO
ALREADY SATURATED SOILS AND RUNOFF FROM LATE SEASON HIGH ELEVATION
SNOWPACK. IF YOU LIVE IN OR NEAR A BURN SCAR...BE MINDFUL OF THE
FLASH FLOOD POTENTIAL. IN ADDITION...HEAVY RAINFALL WITH EXPECTED
FULL RUNOFF WILL LEAD TO A HIGH FLOOD POTENTIAL FOR AREA RIVERS
AND STREAMS. PAY ATTENTION TO FORECAST UPDATES AND BE PREPARED FOR
HEAVY RAINFALL FLOODING THAT MAY IMPACT YOUR AREA.

SATURDAY-SUNDAY...BROAD UPPER TROUGH CONTINUES TO SLOWLY LIFT NORTH
AND EAST ACROSS THE STATE...WITH SCATTERED TO NUMEROUS AFTERNOON AND
EVENING SHOWERS AND STORMS...BEST COVERAGE...OVER AND NEAR THE
HIGHER TERRAIN. WITH AMPLE RESIDUAL MOISTURE AND CONTINUED SATURATED
SOILS...LOCALIZED FLASH FLOODING WILL STILL BE A CONCERN INTO THE
WEEKEND.

MONDAY-WEDNESDAY...A SLOW WARMING AND DRYING TREND REMAINS ON TAP AS
DRIER AIR WITHIN MODERATE WEST TO SOUTHWEST FLOW ALOFT IS PROGGED TO
DEVELOP ACROSS THE REGION. THIS PATTERN WOULD SUGGEST A SLOW DRYING
OF AVAILABLE MOISTURE LEADING TO MORE ISOLATED...DIURNALLY AND
TERRAIN DRIVEN CONVECTION.

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z THURSDAY EVENING)
ISSUED AT 343 PM MDT WED JUN 10 2015

REMNANTS OF BLANCA TRACKING EAST ACROSS THE REGION LATE THIS
AFTERNOON BRINGING A LINE OF SHOWERS AND THUNDERSTORMS...CREATING
AREAS OF MVFR/IFR/LIFR CONDITIONS LOCALLY WITHIN THE ACTIVITY. THIS
ACTIVITY WILL IMPACT KCOS...KPUB AND KALS TAF SITES. MOST OF THIS
ACTIVITY SHOULD MOVE EAST OF THE FLIGHT AREA BY ABOUT 03Z THIS
EVENING...ALTHOUGH SOME SPOTTY ACTIVITY WILL LINGER OVERNIGHT.
GENERALLY VFR CONDITIONS ACROSS MOST OF THE FLIGHT AREA DEVELOPING
AFTER 03Z. CONVECTIVE ACTIVITY WILL BEGIN TO INCREASE AGAIN OVER THE
MOUNTAINS 15-18Z THURSDAY...AND SPREAD EAST ACROSS THE PLAINS 12 TO
18Z...WITH INCREASING SHOWERS AND THUNDERSTORMS THROUGHOUT THE DAY
BECOMING STRONG TO SEVERE LATE.
