AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PUEBLO CO
435 AM MDT SAT JUL 31 2010

.SHORT TERM...

(TONIGHT AND SATURDAY)

...POTENTIAL FOR HEAVY RAIN AND FLOODING CONTINUES...

WILL HAVE TO BE SOMEWHAT BRIEF WITH ONGOING FLOODING CONCERNS.
NOT MUCH CHANGE TODAY...WITH THE MONSOON PLUME HANGING AROUND
THRU TONIGHT. PREC H2P REMAINS AT 150-250 PERCENT. ABUNDANT LOW LVL
MOISTURE...WITH DEWPOINTS GENERALLY IN THE LOWER 60S ACROSS THE
PLAINS. TRANSPORT WINDS A TAD STRONGER TODAY...SO THAT MAY HELP
TO SOME EXTENT...BUT WITH NUMEROUS SITES REPORTING BETWN 1-2 INCHES
OF RAINFALL ON FRI-FRI NITE...WILL NOT TAKE MUCH ADDITIONAL RAINFALL
O CAUSE PROBLEMS. STILL SEEING FLOODED STREETS ON THE SOUTH SIDE OF
PUEBLO THIS MORNING WITH MODERATE RAIN CONTINUING ATTM. OTHER
HOT SPOTS INCLUDE CROWLEY AND WRN KIOWA COUNTIES...WETS AND SANGRES
SOUTH OF HGWY 96...AND RATON AREA E AND S OF TRINIDAD. RADAR ESTIMATES
OF 2-4 INCHES OR HIGHER FOR SOME OF THESE LOCATIONS. HAVE EXTENDED
OUR FLOOD WATCH TO INCLUDE THOSE AREAS ON THE PLAINS THAT HAVE
RECEIVED HEAVY RAINFALL OVERNIGHT...AND ALSO MOVED UP THE STARTING
TIME OF THE WATCH SINCE THERE IS THE CHANCE FOR HEAVY RAINFALL TODAY
EVEN DURING THE MORNING HOURS. HAVE GONE BELOW GUIDANCE TODAY FOR
TEMPS...WITH ABUNDANT PRECIP AND CLOUD COVER KEEPING TEMPS AT OR
BELOW SEASONAL NORMS. PRECIP SHOULD WIND DOWN BY LATER THIS EVE. ROSE

.LONG TERM...

(SUNDAY THROUGH FRIDAY)

MODELS CONTINUE TO BE IN GOOD AGREEMENT THROUGH THE EXTENDED WITH
VERY LITTLE CHANGE EXPECTED IN THE OVERALL PATTERN. HIGH PRESSURE
WILL CONTINUE TO DRIFT EAST OVER THE CENTRAL PLAINS WITH ABUNDANT
MOISTURE AND SEVERAL WEAK DISTURBANCES MOVING NORTHWARD FROM THE
DESERT SOUTHWEST. A DISTURBANCE WILL TRACK NORTHEAST ACROSS
COLORADO SUNDAY WITH ANOTHER ROUND OF HEAVY RAINFALL DEVELOPING
ALONG THE CONTINENTAL DIVIDE AND EASTERN MOUNTAINS. MODELS IN
AGREEMENT WITH THUNDERSTORMS REMAINING TIED TO THE TERRAIN SO
EXPECT LITTLE PRECIP EAST OF THE I-25 CORRIDOR SUNDAY AFTERNOON
AND EVENING. ABUNDANT LOW LEVEL MOISTURE WILL ONCE AGAIN PRODUCE
LOCALLY HEAVY RAINFALL WITH FLASH FLOODING BEING A
THREAT...ESPECIALLY OVER AREAS THAT HAVE SEEN HEAVY RAIN THE PAST
FEW DAYS.

THE NEXT DISTURBANCE WILL ROTATE AROUND THE HIGH AND ACROSS
COLORADO ON MONDAY. THERE IS SOME MODEL DISCREPANCIES WITH A FRONT
AND CONVERGENCE MAX LOCATED NORTH OF HIGHWAY 50 AND WHETHER
CONVECTION WILL BREAK OUT ALONG THIS FRONT MONDAY EVENING.
THUNDERSTORMS WILL DEVELOP BY THE AFTERNOON ALONG THE CONTINENTAL
DIVIDE AND EASTERN MOUNTAINS AND SPREAD EAST ALONG THE ADJACENT
PLAINS THROUGH THE EVENING. MODELS ARE IN AGREEMENT DEVELOPING A
SURFACE LOW NEAR PUEBLO WITH AN AREA OF STRONG CONVERGENCE
DEVELOPING NORTH OF HIGHWAY 50 BY 00Z. THE NAM DEVELOPS VERY
LITTLE CONVECTION ALONG THIS BOUNDARY AS IT STALLS OVER THE
EASTERN PLAINS DURING THE OVERNIGHT HOURS. THE GFS IS MORE BULLISH
WITH CONVECTION WITH EXTRA LIFT PROVIDED FROM A WEAK DISTURBANCE
OVER NORTHEAST COLORADO. CURRENT THINKING IS CONVECTION WILL
DEVELOP NORTH OF HIGHWAY 50 AFTER 00Z HOWEVER THE AMOUNT OF
COVERAGE REMAINS UNCERTAIN. HEAVY RAINFALL AND FLOODING WILL ONCE
AGAIN BE A THREAT THROUGH MONDAY NIGHT.

THE PATTERN IS FORECAST TO PERSIST THROUGH FRIDAY WITH UPPER LEVEL
DISTURBANCES ROTATING ACROSS COLORADO AND THUNDERSTORMS WITH HEAVY
RAINFALL...ESPECIALLY OVER THE HIGHER TERRAIN TO THE WEST.
INCREASED FLOW ALOFT WILL HELP WITH STORM MOTIONS BY MIDWEEK
SOMEWHAT REDUCING THE FLASH FLOODING THREAT...HOWEVER WITH
SATURATED SURFACE CONDITIONS...THINK THE THREAT WILL CONTINUE.
AFTERNOON TEMPERATURES WILL REMAIN WARM THROUGH THE EXTENDED WITH
UPPER 80S TO MID 90S FOR THE PLAINS AND 70S TO 80S FOR THE HIGHER
TERRAIN TO THE WEST.  MOZLEY

.AVIATION...

HEAVY RAINFALL FROM SCT-NMRS SHWRS AND TS TODAY IS AGAIN THE MAIN
CONCERN...ESPECIALLY FOR KCOS AND KPUB. COULD ALSO SEE SOME PATCHY

SURFACE CONDITIONS. ROSE

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

.DAY ONE...TODAY AND TONIGHT

SCATTERED TO NUMEROUS THUNDERSTORMS ARE EXPECTED OVER THE MOUNTAINS
AND ADJACENT PLAINS THROUGH THIS EVENING. SMALL HAIL UP TO DIME SIZE
MAY ACCOMPANY THE STRONGER STORMS...BUT THE MAIN THREAT WILL BE FROM
LOCALLY HEAVY RAINFALL WHICH WILL ONCE AGAIN BRING THE POTENTIAL FOR
FLASH FLOODING. MUD OR ROCK SLIDES WILL BE OF PARTICULAR CONCERN FOR
THE MOUNTAIN AREAS. URBAN AREAS AND AREAS WITH POOR RUNOFF WILL ALSO
BE SUSCEPTIBLE TO FLOODING TODAY.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

A PERSISTENT PATTERN WILL KEEP ACTIVE WEATHER ACROSS SOUTHERN
COLORADO THROUGH FRIDAY. SHOWERS AND THUNDERSTORMS ARE FORECAST TO
DEVELOP ALONG THE CONTINENTAL DIVIDE AND EASTERN MOUNTAINS AND
SPREAD INTO THE PLAINS WEST IF INTERSTATE 25 AND OVER THE PALMER
DIVIDE THROUGH THE EVENING HOURS. ABUNDANT MOISTURE AND SLOW STORM
MOTIONS WILL LEAD TO LOCALLY HEAVY RAINFALL AND THE POTENTIAL FOR
FLASH FLOODING...ESPECIALLY OVER LOCATIONS THAT HAVE SEEN HEAVY
RAINFALL FOR CONSECUTIVE DAYS. THERE IS LESS CERTAINTY IN
THUNDERSTORM COVERAGE OVER THE PLAINS WITH THE BEST CHANCES BEING
EARLY NEXT WEEK. THUNDERSTORMS THAT OCCUR THROUGH FRIDAY WILL BE
CAPABLE OF PRODUCING PEA SIZE HAIL AND LIGHTNING IN ADDITION TO
HEAVY RAINFALL.

.SPOTTER INFORMATION STATEMENT...

WEATHER CONDITIONS THAT MEET REPORTING CRITERIA FOR SPOTTERS WILL BE
POSSIBLE OVER SOUTHEAST COLORADO THROUGH THIS EVENING.
