.UPDATE...
ISSUED AT 710 AM MDT SUN AUG 10 2014

UPDATED MAINLY TO ADJUST SKY COVERAGE PER SAT AND TRENDS. ROSE

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 333 AM MDT SUN AUG 10 2014

...RISK OF FLOODING TODAY...

CURRENTLY...A FEW LINGERING SHOWERS OVER BACA COUNTY AND ERN LAS
ANIMAS...WHICH SHOULD DISSIPATE BY SUNRISE. DEW POINTS ARE GENERALLY
IN THE 50S ACROSS THE PLAINS...AND 30S-40S FOR THE MT AREAS. AREA IS
UNDER NW FLOW ALOFT TODAY AS THE UPPER HIGH BEGINS TO NUDGE EWD.

MAIN CONCERN TODAY WILL BE THE THUNDERSTORM COVERAGE LATER TODAY.
WITH UPSLOPE IN PLACE AND RESPECTABLE LLVL MOISTURE...EXPECT GOOD
COVERAGE OF STORMS LATER TODAY. NOT A GREAT DEAL OF INSTABILITY TO
WORK WITH...BUT WILL NOT TAKE MUCH WITH DAYTIME HEATING TO GET
THINGS GOING OVER THE MTS BY NOON. THEN...WILL SEE STORMS SHIFT
EWD LATER THIS AFTERNOON. A DISTURBANCE NOTED IN THE PV FIELDS
WILL MOVE THROUGH BY 00Z...AND THE FOLLOWING 6-9 HOURS THIS
EVENING WILL BE THE BEST WINDOW FOR HEAVY RAINFALL. MODELS DIFFER
A BIT ON WHERE THE GREATEST STORM COVERAGE WILL FALL...BUT
CONSENSUS IS THAT IT WILL PROBABLY BE ALONG THE WEAK H7 BAROCLINIC
ZONE THAT SETS UP OVER SERN CO. WRF MODELS SHOW BEST COVERAGE
ALONG I-25...ESPECIALLY OVER THE PIKES PEAK
REGION...PUEBLO...HUERFANO...AND LAS ANIMAS COUNTIES FROM 00Z
THROUGH ABOUT 06Z. NOT EXPECTING THE CONVECTION TO BE THAT
STRONG...BUT TRAINING CELLS AND REDEVELOPMENT COULD LEAD TO SOME
PROBLEMS...ESPECIALLY OVER THE BURN SCARS. WILL DEFINITELY BE A
HEIGHTENED RISK COMPARED TO THE LAST FEW DAYS AND THE NEXT FEW
DAYS TO COME. SVR THREAT LOOKS LOW BUT CANNOT RULE OUT SOME SMALL
HAIL AND STRONG WIND GUSTS IN THE STRONGER CELLS. TEMPS SHOULD TOP
OUT IN THE 80S OVER THE PLAINS TODAY.

SHOULD SE THINGS WIND DOWN AFTER MIDNIGHT TONIGHT...WITH JUST A FEW
LINGERING STORMS OUT OVER THE PLAINS AND THE RATON MESA AREA.
ANOTHER FAIRLY MILD NIGHT EXPECTED WITH TEMPS AROUND 60 FOR THE
PLAINS AND 40S FOR THE HIGH VALLEYS AND MTN AREAS. ROSE

.LONG TERM...(MONDAY THROUGH SATURDAY)
ISSUED AT 333 AM MDT SUN AUG 10 2014

...BEST CHANCE OF HEAVIER RAIN WED AND THU...

WITH DOMINANT RIDGE EXPECTED OVER THE REGION FOR THE NEXT COUPLE
OF DAYS (MON AND TUE) BEST CHANCE OF POPS WILL BE IN THE
MTNS...WITH ONLY ISOLD POPS ON THE PLAINS. WITH FLOW NNW AT
MIDLVLS...AND NO WELL DEFINED FORCING ON THE PLAINS...STORMS OVER
THE HIGHER TRRN WILL HAVE A HARD TIME PUSHING OUT INTO THE PLAINS.
LIKEWISE...EXPECT ISOLD TO SCTD POPS OVER THE MTNS THROUGH TUESDAY
WITH ONLY ISOLD POPS AT BEST AT LOWER ELEVATIONS.

BY WED...FLOW BECOMES A BIT MORE ZONAL ALOFT AND GUIDANCE SHOWS A
SLUG OF MONSOON MOISTURE MOVING OVER THE STATE. THIS WILL INCREASE
THE POPS OVER THE CONTDVD...WITH LOCALLY HEAVY RAIN POSSIBLE THIS
REGION. THERE WILL BE BIT BETTER CHANCE OF POPS ON THE PLAINS WITH
STORMS PUSHING OFF THE MTNS ACROSS THE PLAINS.

THURSDAY HAS THE POTENTIAL TO BE THE WETTEST DAY OVER THE ENTIRE
REGION AS WEAK SHORT WAVE WILL COMBINE WITH MONSOON MOISTURE TO
BRING THE POTENTIAL FOR MORE WIDESPREAD PRECIP...SOME LOCALLY
HEAVY...TO THE AREA.

FRIDAY INTO THE WEEKEND...GUIDANCE INDICATING NOTICEABLY DRIER AIR
MOVING INTO THE STATE...AND IF THIS VERIFIES MTNS WILL DRY OUT WITH
ONLY ISOLD POPS ON THE PLAINS.

OVERALL TEMPS WILL BE AT OR SLIGHTLY BELOW SEASONABLE VALUES FOR
THIS TIME OF THE YEAR. ANY THUNDERSTORM FORMING OVER THE BURN
SCARS WILL HAVE THE POTENTIAL TO PRODUCE FLASH FLOODING. /HODANISH

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z MONDAY AFTERNOON)
ISSUED AT 1150 AM MDT SUN AUG 10 2014

MAIN CONCERN WILL BE THE THREAT OF THUNDERSTORMS TODAY FOR ALL 3
TAF SITES. RISK OF STORMS WILL COME EARLY AT KCOS STARTING 19-20Z
...AND PROGRESSIVELY LATER FOR KALS 20-21Z...AND KPUB 22Z. STORMS
COULD LINGER OVER THE I-25 CORRIDOR THROUGH LATE THIS EVENING...
POSSIBLY AFTER 06Z. COULD SEE MVFR-IFR CIGS WITH THE STRONGER
CELLS IMPACTING THE TERMINALS...ALONG WITH SOME SMALL HAIL AND
BRIEF WIND GUSTS 40 TO 50 MPH LOCALLY.
