445 PM MDT TUE JUL 15 2014
.SHORT TERM...(TONIGHT THROUGH WEDNESDAY NIGHT)
ISSUED AT 301 PM MDT TUE JUL 15 2014
SHORT WAVE OVER WYOMING WILL SLIDE SOUTHEAST WITH MUCH OF THE
IMPACT STAYING NORTH AND EAST OF THE FORECAST AREA. HOWEVER
GRADIENT FLOW DOES INCREASE ACROSS THE NORTHERN HALF THIS
AFTERNOON AND THERE IS WEAK QG ASCENT. SHEAR HAS INCREASED ACROSS
THE REGION...MORE SO TOWARD THE WYOMING BORDER. TERRAIN DRIVEN
STORMS WILL ROLL OFF THE HIGHER "HILLS" AND IMPACT VALLEY SPOTS.
NO SURPRISE THAT MORE CELLS HAVE DEVELOPED ACROSS THE NORTH...MANY
OF THESE ARE LIVING LONGER THAN THE TYPICAL PULSE STORMS.
THE SAN JUAN MOUNTAINS HAVE BEEN A LITTLE SLOWER TO FIRE THIS
AFTERNOON...BUT EXPECT THIS TO CHANGE. SW COLORADO HAS THE
DEEPEST MOISTURE AND CURRENTLY HAS PLENTY OF SUNSHINE. UNLIKE
YESTERDAY WHERE STORM MOTION WAS FROM NORTHEAST TO SOUTHWEST...TODAY
STORM MOTION IS NORTHWEST TO SOUTHEAST. THIS CHANGE IN STORM
MOTION MAY BE NOT BE QUITE AS FAVORABLE FOR WIDESPREAD STORM
COVERAGE AND HEAVY SHOWERS. MESO VORT SHIFTED INTO NE ARIZONA
EARLIER TODAY. HAVING SAID THAT...STORM MOVEMENT REMAINS WEAK AND
DEEP CONVECTION IS EXPECTED TO DEVELOP OVER SOUTHWEST COLORADO AND
SHOULD EXPAND THIS EVENING. LOCALIZED HEAVY RAINS MAY OCCUR OVER
THE SAN JUANS/ABAJOS/LA SALS FOOTHILLS. STORMS WILL BE SLOW TO
DISSIPATE TONIGHT AND WOULD NOT BE SURPRISED IF ISOLATED
THUNDERSTORMS WITH SCATTERED SHOWERS LINGER PAST 09Z (3 AM MDT).
WEDNESDAY...NORTHWEST FLOW COVERS THE WESTERN SLOPE WITH WEAK
CYCLONIC FLOW. THIS SHOULD LEAD TO ANOTHER ROUND OF SHOWERS AND
STORMS OVER THE HIGH COUNTRY WITH ENOUGH SHEAR THAT CELLS WILL
PROPAGATE ACROSS VALLEY SPOTS. BUT DRIER AIR WILL BE FILTERING
INTO ERN UTAH AND WILL QUICKLY SPREAD EASTWARD WEDNESDAY
NIGHT...BRINGING AN END TO CONVECTION EARLY IN THE NIGHT. THIS
DRIER AIR BRINGS QUICKER CLEARING FOR A COOLER NIGHT.
.LONG TERM...(THURSDAY THROUGH TUESDAY)
ISSUED AT 301 PM MDT TUE JUL 15 2014
DRIER...RELATIVELY COOL AND MORE STABLE CONDITIONS ON THU WILL
RESULT IN A MARKED DOWNTURN IN CONVECTIVE ACTIVITY. HOWEVER ENOUGH
MOISTURE WILL LINGER FOR THE DEVELOPMENT OF SOME SHOWERS AND
THUNDERSTORMS...CONFINED MAINLY TO THE SAN JUAN MOUNTAINS.
HIGH PRESSURE WILL AGAIN BUILD TO OUR SOUTH-SOUTHWEST THROUGH THE
WEEKEND AND EARLY NEXT WEEK. THE POSITION OF THIS RIDGE WILL NOT BE
FAVORABLE FOR BRINGING ADDITIONAL SUB-TROPICAL MOISTURE INTO THE
FORECAST AREA. IT WILL BE FAVORABLE FOR INCREASED TEMPERATURES
HOWEVER...WITH HIGHS CLIMBING ABOVE NORMAL BY THE WEEKEND. WHILE
DRIER...THERE WILL BE ENOUGH MOISTURE CIRCULATING UNDER THE HIGH FOR
SOME SHOWERS AND THUNDERSTORMS EACH AFTERNOON...MAINLY TERRAIN
BASED. THE SOUTHERN MOUNTAINS WILL BE FAVORED.
&&
.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z WEDNESDAY EVENING)
ISSUED AT 445 PM MDT TUE JUL 15 2014
SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS WILL CONTINUE TO
SWEEP SOUTHEASTWARD ACROSS THE REGION THIS EVENING. THERE IS A
GOOD CHANCE THESE STORMS WILL LEAD TO BRIEF IFR CONDITIONS IN
HEAVY RAIN AT TAF SITES THROUGH 06Z...ESPECIALLY THOSE IN THE
CENTRAL COLORADO VALLEYS. IN ADDITION...MOUNTAINS WILL BE OBSCURED
AT TIMES.
A DISTURBANCE MOVING ACROSS THE AREA FROM THE NORTHWEST WILL
SUSTAIN SOME SHOWERS AND EMBEDDED THUNDERSTORMS THROUGH THE
REMAINDER OF THE NIGHT...ESPECIALLY ACROSS CENTRAL COLORADO. AS
THIS DISTURBANCE CONTINUES TO THE SOUTHEAST IT WILL BRING
INCREASED THUNDERSTORM ACTIVITY TO SOUTHERN COLORADO WEDNESDAY
MORNING THROUGH WEDNESDAY AFTERNOON. MOUNTAIN AREAS TO THE NORTH
WILL SEE SCATTERED AFTERNOON ACTIVITY.

TBThe Albuquerque radar (KABX), 219 km away, was scanning. The volume nearest the first event began at 01:58 UTC.
1 heavy rain, 1 flash flood. Local standard time, as filed.
A rainfall total of 1.26 inches fell within a two hour period, with most of the precipitation having occurred in less than one hour.
Heavy rainfall resulted in flash flooding within various locations in and near Pagosa Springs. Flowing water about 18 inches deep ran across Highway 160 about a half mile east of the junction with Highway 84. A stream which comes down to Rumbaugh Road in northeast Pagosa Springs had a high volume of water which ran across the road and continued onto Highway 160; with water 6 to 8 inches deep in an area generally bounded on the east and west ends by 1st Street and 2nd Street and bounded on the north and south ends by Lewis Street and Highway 160. Another area of flash flooding occurred on the west end of town in the Bastille Drive area where up to a foot of water depth was reported. Water damage occurred to a number of residences and businesses, including an auto supply store which still had about 12 inches of standing water inside the store the next morning. The river gauge in the San Juan River within Pagosa Springs measured a stage rise of just over 3 feet in less than 1.5 hours. The river rose up to the top of the banks in some places but did not overflow.
