.SHORT TERM...(THIS EVENING THROUGH MONDAY)
ISSUED AT 254 PM MDT SUN AUG 10 2014

...WET THIS EVENING ESPECIALLY ALONG AND NEAR THE MOUNTAINS...

A WET EVENING SHAPING UP FOR MANY ALONG AND NEAR THE MOUNTAINS.
PROGRESSIVELY LESS WIDESPREAD ACTIVITY AS YOU HEAD EAST ACROSS
THE PLAINS TOWARD KANSAS. PRIMARY CULPRITS TONIGHT ARE A STRONG
DISTURBANCE MOVING THROUGH...GOOD AMOUNTS OF AVAILABLE
MOISTURE...LOW LEVEL USPLOPE FLOW...AND SLOW AND/OR BACK BUILDING
STORM MOTIONS. HEAVY RAIN AND FLASH FLOOD POTENTIAL THIS EVENING.
ALSO...SOME HAIL...GENERALLY LESS THAN A HALF INCH THIS EVENING.
OTHER CONCERNS...LIGHTNING AND WIND GUSTS TO 40...OR POSSIBLY 50
MPH ASSOCIATED WITH THE STRONGER CONVECTION.

DRIER TOMORROW...WITH MOST CONVECTION CONFINED TO AREAS IN AND
NEAR THE MOUNTAINS. STILL LOCALLY HEAVY RAIN THREAT ASSOCIATED
WITH THAT CONVECTION. LW

.LONG TERM...(MONDAY NIGHT THROUGH SUNDAY)
ISSUED AT 254 PM MDT SUN AUG 10 2014

...CONVECTION MAINLY CONFINED TO MOUNTAINS AND ADJACENT TERRAIN
THROUGH WEDNESDAY BEFORE TROUGH AFFECTS THE AREA...

MONDAY NIGHT THROUGH WEDNESDAY...UPPER RIDGE WILL BE POSITIONED OVER
THE ROCKIES...BUT WITH SOME LOW LEVEL AND MONSOON MOISTURE ACROSS
THE CWA...EXPECT DIURNAL SHOWERS AND STORMS TO OCCUR DURING THE
AFTERNOON AND EVENING HOURS.  CAPE VALUES ARE BELOW 1000 J/KG...SO
WOULD NOT EXPECT ANYTHING MORE THAN MARGINAL PULSE SEVERE STORMS.
THE MAIN RISKS EACH DAY WOULD BE STORMS THAT HIT BURN SCARS WITH
LOCALLY HEAVY RAIN. CHANCES FOR RAIN ON THE PLAINS WILL BE QUITE
LOW... WHERE THE MOST STABLE AIR WILL BE...AND THE MONSOON
PLUME...AS HAS BEEN ADVERTISED FOR THE PAST SEVERAL DAYS...WITH BE
OVER WESTERN COLORADO...SO WE WILL BE WATCHING THE WEST FORK COMPLEX
BURN SCARS CLOSELY.

WEDNESDAY NIGHT THROUGH THURSDAY...THE GFS AND EUROPEAN HAVE SIMILAR
SOLUTIONS BUT DETAILS ARE DIFFERENT IN THE CURRENT AVAILABLE RUNS.
GFS IS MORE PROGRESSIVE WITH SHORTWAVE RIPPLING THROUGH THE MAIN
TROUGH. THE SPEED OF THE SHORTWAVE WILL DETERMINE THE TIMING OF A
WAVE OF PRECIPITATION MOVING ACROSS THE EASTERN PART OF COLORADO.
RIGHT NOW THE FOCUS FOR THAT IS NORTH OF OUR CWA. THE SPEED OF THAT
FEATURE WILL ALSO DETERMINE THE COVERAGE AND TIMING OF RAINFALL
DURING THURSDAY.  FOR NOW...WILL COVER WILL GENERAL ISOLATED TO
SCATTERED POPS.

FRIDAY THROUGH THE WEEKEND...MODELS INDICATE THAT ZONAL FLOW WILL
PREDOMINATE WITH UPPER LOW TO OUR NORTH...AND MONSOON MOISTURE
SHUNTED TO OUR SOUTH. STILL ENOUGH WEAK INSTABILITY TO PRODUCE
DIURNAL SHOWERS AND STORMS.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z MONDAY AFTERNOON)
ISSUED AT 254 PM MDT SUN AUG 10 2014

MAIN CONCERN WILL BE THE THREAT OF THUNDERSTORMS TODAY FOR ALL 3
TAF SITES. RISK OF STORMS WILL CONTINUE THROUGH THIS EVENING.
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. DRIER TOMORROW
WITH MOST CONVECTION CONFINED TO AREAS IN AND NEAR THE MOUNTAINS.
STILL LOCAL INTENSE CONVECTION POSSIBLE WITH THAT ACTIVITY. LW
