.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 425 AM MDT MON AUG 24 2015

...MAINLY MOUNTAIN STORMS TODAY...

LOW GRADE MONSOON TODAY WITH MAINLY ISOLATED TO SCATTERED AFTERNOON
AND EVENING MOUNTAIN THUNDERSTORMS EXPECTED.  UPPER HIGH CENTER OVER
THE 4 CORNERS REGION TODAY.  THERE IS ENOUGH MONSOON MOISTURE UNDER
THE RIDGE FOR MOUNTAIN STORMS.  OTHERWISE...WARM UPPER RIDGE WILL
CAP MOST CONVECTION OVER SOUTHERN COLORADO.  PRIMARY STORM THREATS
TODAY WILL BE LIGHTNING AND WIND GUSTS TO AROUND 40 MPH. COULD ALSO
BE A LOCALLY HEAVY RAINER OUT THERE.  MOST CONVECTION SHOULD END BY
MIDNIGHT IF NOT SOONER.  TEMPERATURES WILL CLIMB BACK ABOVE AVERAGE
AGAIN TODAY...GENERALLY 3 TO 5 DEGREES ABOVE AVERAGE IN MOST CASES.

.LONG TERM...(TUESDAY THROUGH SUNDAY)
ISSUED AT 425 AM MDT MON AUG 24 2015

TUESDAY...UPPER RIDGE PERSISTS OVER COLORADO. SOME MID LEVEL
MOISTURE WILL REMAIN TRAPPED UNDER THE RIDGE FOR ISOLATED TO
SCATTERED CONVECTION CONFINED TO OVER AND NEAR THE MOUNTAINS.
TEMPERATURES ALOFT WILL CONTINUE TO BE WARM WITH AFTERNOON HIGHS
ABOVE AVERAGE AT MOST LOCATIONS.

WEDNESDAY AND THURSDAY...WITH A TROUGH DIVING SOUTHWARD ALONG THE
WEST COAST...SOUTHERLY FLOW ALOFT WILL BRING MORE MIDDLE AND UPPER
LEVEL MONSOON MOISTURE INTO THE REGION. GFS GRADUALLY BRINGS THE
MOISTURE ASSOCIATED WITH THE WEAKENING MCS OVER THE GULF OF
CALIFORNIA NORTHWARD. CURRENTLY...IT APPEARS THAT THE BEST
MOISTURE WILL REMAIN OVER THE WESTERN HALF OF THE STATE. GRIDS
HAVE HIGH SCATTERED TO LIKELY POPS FOR THE SOUTHWEST AND CENTRAL
MOUNTAINS WEDNESDAY WITH POPS DECREASING TOWARDS THE EAST. OVER
THE PLAINS...LEE TROUGH WILL DEVELOP WHICH WILL PREVENT THE
DEEPER MOISTURE OVER KANSAS FROM MOVING WESTWARD INTO THE REGION.
THIS SHOULD LOWER THE POPS AND THREAT FOR HEAVY RAINS OVER THE
PLAINS AND EASTERN MOUNTAINS. THE MODELS CONTINUE TO DEVELOP A
TROUGH WITH THIS POOL OF MOISTURE WITH THE TROUGH MOVING ACROSS
EASTERN COLORADO ON THURSDAY. CURRENT TIMING HAS THE TROUGH
PASSING THROUGH THURSDAY MORNING...BEFORE THE TIME OF PEAK
HEATING. THIS SHOULD LIMIT CHANCES FOR STORMS ON THE PLAINS.
NUDGED UP POPS NEAR THE KANSAS BORDER SINCE TROUGH WILL PASS THESE
LOCATIONS LATER IN THE MORNING OR EARLY AFTERNOON.

FRIDAY THROUGH SUNDAY...TROUGH WILL MOVE ONSHORE OVER THE PACIFIC
NORTHWEST...TURNING THE FLOW ALOFT SOUTHWESTERLY. THIS WILL BRING
DRIER AIR INTO THE REGION...BUT THERE COULD STILL BE ENOUGH
MONSOON MOISTURE FOR SOME AFTERNOON AND EVENING STORMS...MOSTLY
OVER AND NEAR THE MOUNTAINS. TEMPERATURES ALOFT WILL REMAIN WARM
FOR A WARM WEEKEND.  --PGW--

LIMITED MONSOON MOISTURE OVER COLORADO TODAY. ENOUGH MOISTURE
REMAINS IN PLACE FOR ISOLATED TO LOW END SCATTERED THUNDERSTORMS
OVER THE MOUNTAINS. WEAK NORTHERLY FLOW ALOFT MAY ALLOW STORMS TO
DRIFT SOUTH ACROSS THE HIGH VALLEYS. FOR THE COS...PUB AND ALS
