AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER CO
1258 PM MDT THU JUL 14 2011

.UPDATE...

&&

.SHORT TERM...STORMS HAVE DEVELOPED MORE QUICKLY THEN EXPECTED OVER THE
FOOTHILLS WITH SOME TRAINING ECHOES ALREADY TAKING PLACE SO THE
FLASH FLOOD WATCH WAS MOVED UP TO START AT NOON FOR THE FOOTHILLS
AND ADJACENT PLAINS. ACARS SOUNDINGS INDICATE THE PLAINS STILL
NEED TO HEAT UP TO 90 OR SO TO REACH CONVECTIVE TEMPERATURE SO
HAVE KEPT THE FLASH FLOOD WATCH AS IS THERE. SOME STORMS COULD
BECOME SEVERE COMING OFF THE FOOTHILLS EVEN OVER THE NEXT COUPLE
OF HOURS. STILL EXPECTING AN INCREASE IN TOTAL PRECIPITABLE WATER
AS MORE MOISTURE COMES NORTH OUT OF NM AND HAVE INDEED SEEN
INCREASE OVER THE LAST COUPLE OF HOURS AT MOST SITES.

.AVIATION...MAY NEED TO MOVE UP THE START TIME FOR TSTMS
ESPECIALLY AT APA AND BJC AND MAYBE BY AN HOUR OR TWO EVEN AT DIA.

&&

.HYDROLOGY...SO FAR THE TRAINING ECHOES HAVE BEEN ALIGNED BETWEEN
THE BURN AREAS BUT NEW DEVELOPMENT TO THE WEST IS THREATENING THE
FOUR MILE BURN AREA SO WARNING UPCOMING THERE.

&&

.PREV DISCUSSION... /ISSUED 405 AM MDT THU JUL 14 2011/

SHORT TERM...IT LOOKS LIKE ANOTHER LATE AFTERNOON AND EVENING
FILLED WITH THUNDERSTORMS ACROSS MUCH OF THE FORECAST AREA.  WATER
VAPOR PICTURES SHOW A NEW SURGE OF MID-LEVEL MOISTURE MOVING
NORTHWARD OUT OF NEW MEXICO THIS MORNING.  AN UPPER LEVEL HIGH
REMAINS OVER TEXAS WITH MOIST SOUTHWESTERLY FLOW CONTINUING ACROSS
COLORADO.  AT LOWER LEVELS...HIGH PRESSURE ON THE PLAINS AND LOW
PRESSURE OVER WESTERN AND CENTRAL COLORADO WILL KEEP WEAK
SOUTHEASTERLY FLOW GOING ACROSS EASTERN COLORADO.  DAYTIME HEATING
WILL AGAIN BE SUFFICIENT TO DE-STABILIZE THE MOIST AIRMASS LATE IN
THE DAY.  QPF FIELDS FROM THE NAM AND GFS BOTH SHOW CONVECTIVE
PRECIPITATION DEVELOPING AND SPREADING ACROSS NORTHEAST COLORADO
AFTER 00Z.  THIS AFTERNOON WILL ALSO FEATURE A 60 KNOT UPPER LEVEL
JET ARCING OVER NORTHWEST COLORADO WHICH MAY HELP STORMS TO ORGANIZE
IN A TRAINING PATTERN THROUGH THE EVENING.  MODEL SOUNDINGS AGAIN
SHOW PRECIPITABLE WATER VALUES IN EXCESS OF AN INCH ACROSS NORTHEAST
COLORADO WITH CAPE VALUES GREATER THAN 1000 J/KG.  DEW POINTS WILL
AGAIN BE IN THE UPPER 50S AND LOWER 60S...HELPING TO FUEL THE  LATE
AFTERNOON AND EVENING CONVECTION AND MAKING THE SHOWERS EFFICIENT
PRODUCERS OF RAINFALL.  LOW AND MID LEVEL WINDS WILL NOT BE THAT
STRONG...AND MODEL SOUNDINGS SHOW STORM MOTIONS BETWEEN 5 AND 15
KNOTS.  SOIL CONDITIONS ACROSS MUCH OF THE FORECAST AREA ARE ALSO
NEAR SATURATION DUE TO REPEATED ROUNDS OF SHOWERS OVER THE PAST
WEEK.  THE COMBINATION OF SLOW MOVING STORMS...CAPABLE OF PRODUCING
LOCALLY HEAVY RAINFALL...AND THE ANTECEDENT SOIL CONDITIONS MAKE IT
NECESSARY FOR A FLASH FLOOD WATCH FOR THE FOOTHILLS AND MOST OF THE
PLAINS.  WILL RUN THE WATCH FROM 3 PM THROUGH MIDNIGHT.

LONG TERM...LITTLE TO ADD TO THE PREVIOUS FORECASTS.  A WEAK
SOUTHERLY FLOW WILL CONTINUE OVER COLORADO FRIDAY THROUGH SUNDAY.
THE UPPER LEVEL RIDGE WILL BE CENTERED OVER EASTERN KANSAS AND
MISSOURI ON FRIDAY...AND APPEARS TO SHIFT SLIGHTLY WESTWARD BY EARLY
NEXT WEEK.  WEAK DISTURBANCES MIGRATING AROUND THE RIDGE THROUGH
THIS WEAK FLOW WILL BE DIFFICULT TO DETECT...BUT WILL ELEVATE THE
THUNDERSTORM POTENTIAL WHEN THEY MIGRATE ACROSS THE CWFA.  AS FAR AS
THE MSTR IS CONCERNED...THE 00Z NAM12 SOUNDINGS ARE PROGGED TO BE
DRIER AT DENVER AND LIMON I HAD A HARD TIME BELIEVING THE MID 40S
DEWPOINTS DEPICTED IN THE SOUNDINGS.  SREF STILL MAINTAINS DEWPOINTS
IN THE 50S...AND THIS SEEMS MORE BELIEVABLE CONSIDERING HOW
SATURATED THE SOILS HAVE BECOME OVER THE LAST SEVERAL DAYS AND THE
WEAK AND RELATIVELY MOIST FLOW ALOFT.  WITH THIS IN MIND...THE FCST
SOUNDINGS ON FRIDAY SHOULD CHANGE VERY LITTLE.  WITH DEWPOINTS
MODIFIED IN THE 50S...THE PRECIPITABLE WATER VALUES FROM THE NAM12
SOUNDINGS SHOULD STILL OVER ONE INCH WITH CAPES FM 1000-2000 J/KG...
WET MICROBURSTS WITH LOCALLY HEAVY RAIN AND STRONG WINDS THE MAIN
ISSUES.  ALTHOUGH THERE MAY BE SOME DRYING IT WILL NOT BE
SIGNIFICANT.  THEREFORE SEE NO REASON TO ALTER THE GRIDS FOR
SATURDAY AND BEYOND WITH A CHANCE OF AFTERNOON AND EVENING
THUNDERSTORMS EACH DAY.

AVIATION...VFR CONDITIONS ARE EXPECTED TO CONTINUE THROUGH THE LATE
AFTERNOON.  MVFR AND POSSIBLY IFR CIGS AND VSBYS ARE EXPECTED AFTER
22Z AND THROUGH THE EVENING AS THUNDERSTORMS MOVE ACROSS THE METRO
AREA.  THUNDERSTORMS WILL CONTAIN LOCALLY HEAVY RAINS...BUT MAY ALSO
PRODUCE HAIL AND GUSTY OR DAMAGING WINDS.  THUNDERSTORM ACTIVITY
OVER THE METRO AREA MAY AGAIN CONTINUE THROUGH 05Z.  STORMS WILL
ALSO MOVE THROUGH THE WESTER APPROACH GATES DURING THE AFTERNOON AND
THROUGH THE EASTERN GATES LATER IN THE EVENING.

HYDROLOGY...SNOWMELT RUNOFF CONTINUES TO KEEP THE FRASER RIVER AND
THE UPPER COLORADO RUNNING AT OR JUST ABOVE BANKFULL IN GRAND
COUNTY.  IN SUMMIT COUNTY...THE BLUE RIVER HAS BEEN RUNNING NEAR
BANKFULL BECAUSE OF SNOWMELT AND RECENT HEAVY RAINS.  SOME
IMPROVEMENT IS EXPECTED OVER THE NEXT COUPLE DAYS SINCE HEAVY RAIN
SHOWERS HAVE NOT OCCURRED SINCE EARLIER IN THE WEEK.

IN THE FOURMILE BURN AREA...A PAIR OF THUNDERSTORMS MOVED OVER THE
BURN AREA WEDNESDAY EVENING.  THE FIRST THUNDERSTORM PRODUCED
RAINFALLS BETWEEN .80 AND 1.40 INCHES IN 30 TO 45 MINUTES.  CREEKS
IN THE BURN AREA HAD RAPID RESPONSES.  DEBRIS FLOWS AND SOME ROAD
WASHOUTS OCCURRED.  ANOTHER TUNDERSTORM LATER IN THE EVENING
PRODUCED AROUND A QUARTER OF AN INCH IN 15 MINUTES.  CREEKS ROSE
RAPIDLY AND ADDITIONAL DEBRIS FLOWS WERE OBSERVED.  WITH SOIL
CONDITIONS NEAR SATURATION TODAY...ADDITIONAL THUNDERSTORMS MOVING
OVER THE BURN AREA WILL CONTINUE CAUSING ADDITIONAL DEBRIS FLOWS AND
RAPID RISES IN CREEK LEVELS.

A FLASH FLOOD WATCH WILL BE IN EFFECT THIS AFTERNOON AND EVENING FOR
THE FOOTHILLS AND MUCH OF THE PLAINS BECAUSE SOIL CONDITIONS ACROSS
MUCH OF THE FORECAST AREA ARE NEAR SATURATION BECAUSE OF RAINFALLS
THAT HAVE OCCURRED EACH DAY FOR THE PAST WEEK.

...FLASH FLOOD WATCH IN EFFECT FOR THE FRONT RANGE FOOTHILLS AND
MUCH OF NORTHEAST COLORADO THIS AFTERNOON AND EVENING...

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTHEAST AND NORTH CENTRAL
COLORADO.

.DAY ONE...TODAY AND TONIGHT

MONSOONAL FLOW ALOFT CONTINUES OVER COLORADO WITH SOME INCREASE IN
MOISTURE MOVING NORTHWARD FROM NEW MEXICO FOR THIS AFTERNOON AND
EVENING.  IN ADDITION LOW LEVEL MOISTURE REMAINS IN PLACE WITH SOUTH
TO SOUTHEASTERLY FLOW ACROSS THE PLAINS.  WITH THIS COMBINATION
ANOTHER ROUND OF AFTERNOON AND EVENING THUNDERSTORMS WILL DEVELOP
ACROSS NORTHEAST COLORADO AS TEMPERATURES RISE ABOVE 90 ON THE
PLAINS.  SEVERE STORMS ARE ALSO POSSIBLE...SIMILAR TO
YESTERDAY...WITH LARGE HAIL AND DAMAGING WINDS THE MAIN THREAT.
ALTHOUGH THE THUNDERSTORMS ARE EXPECTED TO KEEP MOVING AT ABOUT 15
TO 20 MPH FROM THE SOUTHWEST THEY WILL STILL BE CAPABLE OF PRODUCING
ONE TO TWO INCHES OF RAINFALL IN 30 TO 45 MINUTES.  THE COMBINATION
OF LOCALLY HEAVY RAINFALL AND MOIST SOIL CONDITIONS WILL PRODUCE A
THREAT OF FLASH FLOODING.  A FLASH FLOOD WATCH WILL BE IN EFFECT FOR
THE FRONT RANGE FOOTHILLS AND MOST OF THE NORTHEAST PLAINS FROM 3 PM
THROUGH MIDNIGHT.

THE FLASH FLOOD WATCH WILL INCLUDE THE FOURMILE BURN AREA OF CENTRAL
BOULDER COUNTY.  SATURATED SOIL CONDITIONS EXIST IN THE FOURMILE
BURN AREA DUE TO RAINFALL LAST EVENING.  ANY THUNDERSTORMS THAT MOVE
OVER THE BURN AREA THIS AFTERNOON OR EVENING WILL PRODUCE RAPID
RISES ON CREEKS ALONG WITH DEBRIS FLOWS AND ROCK SLIDES.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

LITTLE CHANGE IN THE WEATHER PATTERN IS EXPECTED.  THERE WILL BE A
CHANCE OF AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS ACROSS THE
FORECAST AREA.  THE MAIN THREAT FROM THE THUNDERSTORMS WILL BE WET
MICROBURSTS PRODUCING LOCALLY HEAVY RAIN AND STRONG WINDS.
TEMPERATURES WILL HOVER AROUND SEASONAL NORMALS THROUGH EARLY NEXT
WEEK.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY BE NECESSARY THIS AFTERNOON AND EVENING.
