Severe Thunderstorm Warning 133, NWS Pueblo, CO

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PUEBLO CO
235 PM MDT THU JUL 15 2004

.SHORT TERM...
(TONIGHT AND FRIDAY)

MAIN WEATHER ISSUE FOR THE SHORT TERM IS THE POTENTIAL FOR HEAVY
RAIN.  CWFA CURRENTLY NOTING WARM TO VERY WARM TEMPERATURES AS WELL
AS MOSTLY CLOUDY SKIES OVER THE HIGHER TERRAIN...WHILE THE FAR
EASTERN PLAINS IS EXPERIENCING PARTLY CLOUDY SKIES.  LATEST RADAR
RETURNS INDICATE THAT SCATTERED SHOWERS AND THUNDERSTORMS...SOME
WITH LOCALLY HEAVY RAIN...DEVELOPING MAINLY OVER THE MOUNTAINS AT
THIS TIME.

LATEST SHORT TERM MODELS SUGGEST THAT FRONT CURRENTLY KNOCKING ON
THE DOOR OF NORTHEAST COLORADO TO PUSH INTO CWFA BY FRIDAY MORNING
AND THEN SLIDE INTO EAST-CENTRAL NEW MEXICO BY LATE FRIDAY AFTERNOON.
WITH PRECIPITABLE WATERS IN THE 1 TO 2 INCH RANGE FROM THE EAST
SLOPES OF THE SOUTHERN MOUNTAINS TO THE KANSAS BORDER AND AROUND 1
INCH OVER WESTERN SECTIONS...THEREFORE...HAVE PAINTED HEAVY RAIN IN
UPCOMING GRIDS/ZONES. IN REGARDS TO SEVERE WEATHER...COULD SEE A FEW
STORMS ENTER THE SEVERE CATEGORY TONIGHT AND AGAIN ON FRIDAY...WILL
CONTINUE TO MONITOR.  MAXIMUM TEMPERATURES SHOULD RUN BELOW
CLIMATOLOGY ON FRIDAY. THANKS SURROUNDING OFFICES FOR COORDINATION.

.LONG TERM...
(FRIDAY NIGHT THROUGH THURSDAY)

GENERALLY THE UPR RIDGE WL BE OVR THE AREA WITH MINOR SHIFTS IN ITS
POSITION AT TIMES THROUGH THURSDAY.

FRI NIGHT PRECIPITABLE WATER (PW) VALUES ARE EXPECTED TO RANGE FROM
AROUND .6 OVR WRN PORTIONS OF THE FORECAST AREA...TO AROUND 1.3
INCHES OVR THE FAR SE PLAINS.  700MB FLOW WL BE E OR SE AND LIGHT...
WHILE 500MB FLOW WL BE NW AT 10-15 KTS WHICH IS A LITTLE STRONGER
AND SHOULD HELP TO KEEP STORM MOVING OFF THE MTS...AND THEY SHOULD
BE A LITTLE FASTER MOVING THAN THAN ON WED AND THU.  HOWEVER...WITH
SO MUCH MSTR IN THE ATMOSPHERE THE HEAVY RAIN POTENTIAL WL STILL
EXIST AND AGAIN THE BURN SCARS WL BE MOST SUSCEPTIBLE TO FLASH
FLOODING. BEST RAIN CHANCES WL LIKELY BE OVR THE ERN MTS AND I-25
CORRIDOR WITH THE LOW LVL UPSLOPE FLOW.

ON SATURDAY THE PW VALUES OVR THE SE CO PLAINS DECREASE AND THE
UPSLOPE WL NOT BE AS GOOD SO SLIGHTLY LOWER POPS VALUES LOOK
GOOD. TEMPS LOOK A LITTLE WARMER SAT.

FOR SUN THRU THU NOT MUCH CHANGE NEEDED TO THE CURRENT FORECAST.
MSTR REMAINS TRAPPED UNDER THE UPR RIDGE WITH OCCASIONAL DISTURBANCES
BEING DIFFICULT TO TIME ACCURATELY.  WL LEAVE POPS IN EACH AFTERNOON
AND EVENING AND FOR NOW WL KEEP THEM ISOLD.

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

.DAY ONE...TODAY AND TONIGHT.

MONSOON MOISTURE HAS OVERSPREAD THE AREA DURING THE NIGHT.  THIS WILL
RESULT IN SCATTERED THUNDERSTORMS ACROSS THE MOUNTAINS...HIGH
VALLEYS...AND I-25 CORRIDOR THIS AFTERNOON AND EVENING.  SOME OF
THIS ACTIVITY WILL SPREAD TO THE FAR EASTERN PLAINS TONIGHT.

THE MAIN THREATS FROM STORMS TODAY WILL BE HEAVY RAINS AND LIGHTNING.
ATMOSPHERIC WIND PROFILES SHOW VERY LITTLE STEERING FLOW TO KEEP
STORMS MOVING TODAY.  ADDITIONALLY...MONSOON MOISTURE WILL BE
DEEPENING AS THE AFTERNOON AND EVENING PROGRESS.  CONSEQUENTLY...
THERE WILL BE A GOOD POTENTIAL FOR SLOW MOVING THUNDERSTORMS
PRODUCING HEAVY RAIN ACROSS THE MOUNTAINS AND I-25 CORRIDOR BEGINNING
LATER THIS AFTERNOON...AND CONTINUING THIS EVENING.

A FEW OF THE LARGER...MORE INTENSE STORMS...COULD RESULT IN AREAS OF
URBAN OR SMALL STREAM FLOODING. THIS WOULD BE ESPECIALLY TRUE ACROSS
ANY BURN SCAR...OR ACROSS ANY HIGHLY URBANIZED AREA SUCH AS COLORADO
SPRINGS.  EMERGENCY MANAGERS AND OTHER LOCAL OFFICIALS WITH A BURN
SCAR IN THEIR AREA OF RESPONSIBILITY SHOULD MONITOR WEATHER
CONDITIONS CLOSELY THIS AFTERNOON AND EVENING.  AN INTENSE...SLOW
MOVING THUNDERSTORM...DEVELOPING OVER THE WRONG AREA OF A BURN
SCAR...COULD RESULT IN A FLASH FLOOD.  THIS INCLUDES THE HAYMAN
SCAR IN TELLER COUNTY...THE MILLION SCAR IN RIO GRANDE COUNTY...
THE IRON MOUNTAIN SCAR IN FREMONT COUNTY...AND THE TRINIDAD COMPLEX
SCAR IN LAS ANIMAS COUNTY.

THUNDERSTORM ACTIVITY ACROSS SOUTHERN COLORADO SHOULD DIMINISH AFTER
MIDNIGHT TONIGHT ALTHOUGH SOME ISOLATED SHOWERS AND THUNDERSTORMS MAY
CONTINUE.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY.

SCATTERED THUNDERSTORMS WILL BE POSSIBLE FOR MOST OF SOUTH CENTRAL
AND SOUTHEAST COLORADO FRIDAY AND SATURDAY.  ONE OR TWO STORMS COULD
BECOME STRONG TO SEVERE ON FRIDAY...MAINLY ACROSS THE EASTERN
MOUNTAINS AND SOUTHEAST PLAINS.  LOCALLY HEAVY RAIN...AND
DANGEROUS CLOUD TO GROUND LIGHTNING WILL BE THE PRIMARY THREATS.
HOWEVER LARGE HAIL AND DAMAGING WINDS COULD ALSO OCCUR WITH THE
STRONGER STORMS.  LOCALLY HEAVY RAIN COULD POSE A FLASH FLOOD THREAT
FOR OLD BURN SCARS AND FOR MORE SENSITIVE URBAN AREAS.

THUNDERSTORM CHANCES WILL DECREASE SOME THROUGH THE MID PART OF
NEXT WEEK...ALTHOUGH AT LEAST ISOLATED THUNDERSTORMS WILL BE POSSIBLE
EACH DAY.  ANOTHER COLD FRONT MAY BRING AN INCREASED PROBABILITY FOR
SHOWERS AND THUNDERSTORMS ON WEDNESDAY...ALONG WITH COOLER
TEMPERATURES.

.SPOTTER INFORMATION STATEMENT...

WEATHER CONDITIONS THAT MEET REPORTING CRITERIA FOR SPOTTERS WILL
BE POSSIBLE ACROSS THE MOUNTAINS AND ADJACENT I-25 CORRIDOR AFTER 3
PM TODAY.
