.SHORT TERM...(THIS EVENING THROUGH SUNDAY)
ISSUED AT 209 PM MDT SAT JUL 26 2014

...HEAVY RAIN AND FLOODING POSSIBLE SUNDAY...

FOR MORE DETAILS ON THE FLASH FLOODING POTENTIAL TOMORROW...SEE THE
EARLIER AFD UPDATE AT NOON. FOR THE REST OF TODAY...STILL SOME
CONCERN...MAINLY FOR THE WALDO BURN SCAR...AS SOME HIGH RES GUIDANCE
CONTINUES TO SHOW THE POTENTIAL FOR MODERATE CONVECTION OVER THE
AREA THROUGH 04Z OR SO. TEMPS WORKED OUT NICELY THIS AFTERNOON
WITH UPPER 90S TO AROUND 100 FOR THE ERN PLAINS. THE MONSOON PLUME
IS ORIENTED W-E ACROSS CO...AND WILL CONTINUE TO ROTATE CW AROUND
THE RIDGE THROUGH SUNDAY.

LOOKS LIKE THE COLD FRONT WILL ARRIVE EARLY SUNDAY...PERHAPS AS
EARLY AS 12Z OVER THE PALMER DVD. STILL SOME DISCREPANCIES BETWEENTHE
GFS AND NAM...WITH THE NAM SUGGESTING A WEAKER FRONT AND LESS QPF.
OTHER GUIDANCE IS MORE SUPPORTING OF A WIDESPREAD MDT-HIGH PRECIP
EVENT. AS MENTIONED IN EARLIER DISCUSSION...THE CONCEPTUAL MODEL
FOR A FLOODING EVENT IS IN PLACE AND IT LIKELY TRUMPS ANY
PARTICULAR MODEL SOLUTION. THE MAIN UNKNOWN IS HOW INTENSE PRECIP
WILL BE GIVEN THE EARLY ARRIVAL OF THE FRONT AND CONSEQUENTIAL
STABILIZATION DUE TO WIDESPREAD PRECIP AND CLOUDS. LATER HIGH RES
SOLUTIONS SHOULD SHED SOME LIGHT ON THE QUALITY OF CONVECTION
TOMORROW. THE ONE GIVEN IS THAT IT WILL BE CONSIDERABLY
COOLER...NEARLY 20 DEGREES COOLER ACROSS THE PLAINS. A NICE BREAK
FORM THE HEAT...HOPEFULLY THE RAINS WILL COME SLOWLY ENOUGH THAT
PROBLEMS WILL BE MINIMIZED...BUT EVERYONE SHOULD KEEP A CLOSE EYE
ON THE WEATHER TOMORROW. ROSE

.LONG TERM...(SUNDAY NIGHT THROUGH SATURDAY)
ISSUED AT 209 PM MDT SAT JUL 26 2014

NOT MANY CHANGES TO THE EXTENDED FORECAST...AS AN ACTIVE MONSOON
PATTERN IS STILL EXPECTED. AN BROAD UPR RIDGE OVR THE AREA WL STILL
BE THE MAIN WEATHER FEATURE AFFECTING THE FORECAST AREA THRU THE
PERIOD. MONSOON MOISTURE WL BE STREAMING OVR THE AREA...AND THE LOW
LEVELS WL BE MOIST OVR THE SERN PLAINS...WHERE DEW POINTS WL BE IN
THE 50S. HEAVY RAIN WL BE A THREAT EACH DAY AND ADDITIONAL FLASH
FLOOD WATCHES MAY BE NEEDED...DEPENDING ON THE DAILY THREAT AREA AND
PREVIOUS DAYS RAINFALL AMOUNTS. THE MOUNTAINS AND ADJACENT AREAS WL
SEE THE HIGHEST PCPN CHANCES...BUT STORMS WL ALSO BE FOUND OVR THE
SERN PLAINS.  ON TUE A SHORTWAVE TROF IS FORECAST TO MOVE OVR THE
AREA...POSSIBLY ENHANCING PCPN CHANCES OVR THE SERN PLAINS.  MODELS
STILL SUGGESTING AN MCS DEVELOPING AND KEEPING CONVECTION AND THE
THREAT FOR HVY RAIN ACRS THE SERN PLAINS THRU THE NIGHT AND INTO WED
MORNING.  WITH A MORE MOIST AIR MASS IN PLACE AND INCREASED CLOUD
COVER...HIGH TEMPS WL BE COOLER THROUGH THE WEEK AND WL BE BELOW
AVERAGE OVR THE SERN PLAINS...AND AROUND TO JUST SLIGHTLY BELOW
AVERAGE IN THE SAN LUIS VALLEY.

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z SUNDAY AFTERNOON)
ISSUED AT 209 PM MDT SAT JUL 26 2014

MAIN AVN CONCERNS CONTINUE TO BE THE IMPACT OF A STRONG COLD FRONT
ON SUNDAY. FOR THE REST OF TODAY...STORMS ARE STILL MOST LIKELY TO
IMPACT KCOS BUT COULD OCCUR ANYWHERE...AND BRIEF MVFR CONDITIONS
WILL BE POSSIBLE FROM LOW CIGS AND LOCALLY HEAVY RAINFALL.

THE COLD FRONT WILL MOVE QUICKLY THROUGH EL PASO COUNTY SOMETIME
AFTER 12Z TUE...AND WILL REACH THE NM BORDER BY 18Z. LOW CIGS WILL
BE LIKELY BEHIND THE FRONT BUT WILL NOT NECESSARILY BE WIDESPREAD.
KCOS IS MOST LIKELY TO BE IMPACTED BY MVFR CIGS TUE MORNING.
DEPENDING ON THE TIMING OF THE FRONT...WILL SEE WIDESPREAD SHOWERS
AND/OR TS DURING MUCH OF TUE...THROUGH AT LEAST 00Z. HEAVIEST PRECIP
WILL PROBABLY BE LOCATED ALONG AND E OF I-25...OVER THE E SLOPES OF
THE SRN FRONT RANGE...AND ALONG AND N OF THE RATON MESA. EXTENDED
PERIODS OF MVFR ALONG WITH PERIODS OF IFR-LIFR WILL BE POSSIBLE IN
HEAVIER SHOWERS OR STORMS. ROSE

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF CENTRAL...EAST
CENTRAL...SOUTH CENTRAL AND SOUTHEAST COLORADO.

.DAY ONE...THIS AFTERNOON AND TONIGHT

MONSOON MOISTURE CONTINUES TO SPREAD EAST ACROSS COLORADO.  AS A
RESULT...ANOTHER ROUND OF THUNDERSTORMS IS EXPECTED TO TRACK ACROSS
THE AREA TODAY.  STORMS SHOULD START UP OVER THE MOUNTAINS DURING
THE LATE MORNING HOURS...AND THEN TRACK EAST ACROSS THE PLAINS
DURING THE AFTERNOON AND EVENING HOURS.

WIND SHEAR IS PRETTY WEAK SO THE THREAT OF SEVERE WEATHER IS LOW.
PRIMARY CONCERNS TODAY WILL BE LIGHTNING...LOCALLY HEAVY RAIN...AND
GUSTY WINDS.

AREA BURN SCARS WILL NEED TO BE MONITORED FOR THE POSSIBILITY OF
FLASH FLOODING.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

 FLASH FLOOD WATCH IS IN EFFECT FOR SOUTHEAST COLORADO FOR
THE EASTERN MOUNTAINS...INTERSTATE 25 CORRIDOR...AND MUCH OF THE
PLAINS. A STRONG COLD FRONT WILL ARRIVE SUNDAY MORNING...AND
COMBINED WITH ABUNDANT MONSOONAL MOISTURE WILL RESULT IN A
HIGH THREAT OF LOCALIZED FLOODING...PARTICULARLY OVER AREA
BURN SCARS...URBAN CORRIDORS...AND STEEP TERRAIN. AREA
RESIDENTS SHOULD MAINTAIN A WEATHER AWARENESS ON SUNDAY AND
BE PREPARED TO TAKE ACTION IF FLOODING OCCURS OR IS IMMINENT.

AS STORM MOVE INTO THE SOUTHEAST PLAINS...THEY MAY BRIEFLY BECOME
SEVERE WITH THE THREAT FOR 1 INCH DIAMETER HAIL...AND WIND GUSTS
UP TO 60 MPH...ALONG WITH DANGEROUS CLOUD TO GROUND LIGHTNING.
THESE MAY CONGEAL INTO ONE OR MORE THUNDERSTORM COMPLEXES WHICH
MAY BRING WIDESPREAD HEAVY RAINFALL TO PORTIONS OF THE SOUTHEAST
PLAINS. THIS THREAT LOOKS GREATEST FOR TUESDAY NIGHT. AS THIS
POTENTIAL MULTI-DAY RAINFALL EVENT UNFOLDS...IT IS POSSIBLE THAT
PORTIONS OF THE ARKANSAS AND PURGATORIE RIVERS...ALONG WITH THEIR
TRIBUTARY CREEKS AND STREAMS MAY EXPERIENCE LOCALIZED FLOODING AT
TIMES...THOUGH THIS WILL BE HIGHLY DEPENDENT ON WHERE THE HEAVIEST
RAIN FALLS.

HEAVY RAIN WILL ALSO BE POSSIBLE ACROSS THE SOUTHWEST AND CENTRAL
MOUNTAINS DURING THIS PERIOD...BUT THE THREAT FOR FLASH FLOODING
MAY NOT BE AS WIDESPREAD AS COMPARED TO THE SOUTHEAST MOUNTAINS
AND PLAINS. BURN SCARS WILL BE MOST VULNERABLE TO THIS RISK.

.SPOTTER INFORMATION STATEMENT...

WEATHER CONDITIONS THAT MEET REPORTING CRITERIA FOR SPOTTERS WILL BE
POSSIBLE THIS AFTERNOON AND EVENING ON AREA BURN SCARS.
