AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PUEBLO CO
618 AM MDT SAT AUG 16 2008

.SHORT TERM...
(TODAY AND TONIGHT)

THE DELUGE WILL CONTINUE TODAY.  THE LARGE UPPER LOW HAS TAKEN UP
RESIDENCE OVER NORTHWEST COLORADO THIS MORNING.  AN ACTIVE UPPER JET
IS WRAPPING AROUND THE BASE OF THE LOW THIS MORNING...WITH MOST OF
SOUTHERN COLORADO UNDER THE LIFTING QUAD OF THE JET.  BROAD QG
ASCENT IS PROGGED TO CONTINUE ACROSS SOUTHERN COLORADO...ALONG WITH
MARGINAL INSTABILITY...LOW LEVEL UPSLOPE FLOW...AND DEEP MOISTURE.
SO...ONCE AGAIN TODAY...THE BARRAGE OF SHOWERS AND THUNDERSTORMS
WILL CONTINUE...WITH THE MAIN CONCERN FLOODING.  URBAN AND SMALL
STREAM FLOODING SHOULD BE THE BIGGEST ISSUE.  HOWEVER...SOME OF THE
STORMS YESTERDAY WERE VERY EFFICIENT RAINERS...WITH LOTS OF TINY
DROPS AS WELL AS BIG ONES.  RUNOFF WAS VERY QUICK TO OCCUR.  THIS
HIGH RUNOFF EFFICIENCY...COUPLED WITH ALREADY SATURATED GROUNDS...
COULD PRODUCE A TRUE FLASH FLOOD GIVEN THE RIGHT SCENARIO.  SO...THE
FLASH FLOOD WATCH WILL REMAIN IN EFFECT FOR THE EASTERN MOUNTAINS
AND PLAINS...WHERE STORM COVERAGE AND RAINFALL WILL BE THE
GREATEST.  WATCH FOR RAPIDLY RISING WATER TODAY AND BE PREPARED TO
MOVE TO HIGH GROUND. PRECIPITATION OVER WESTERN AREAS WILL CONTINUE
TO BE LESS WIDESPREAD AND LESS INTENSE.

IN GENERAL...THE SEVERE WEATHER THREAT SHOULD BE DOWN TODAY.
SHEAR VALUES HAVE DROPPED OFF...AND TEMPERATURES WILL RUN JUST A BIT
COOLER THAN YESTERDAY..WHICH MEANS THAT CAPES WILL BE DOWN.  WITH
LESS SHEAR AND LESS CAPE...SHOULD SEE LESS SEVERE WEATHER THREAT.
NOW...HAVING SAID THAT...YOU CAN ALMOST NEVER RULE OUT PULSE SEVERE
STORMS IN EASTERN COLORADO DURING THE SUMMER TIME.  SO...WHILE
SEVERE COVERAGE SHOULD BE DOWN...THERE WILL STILL BE A FEW SEVERE
STORMS AROUND.  PRIMARY THREATS TODAY SHOULD BE HAIL TO 1 INCH IN
DIAMETER...WIND GUSTS TO 60 MPH...HEAVY RAIN AND LIGHTNING.  AS
MENTIONED PREVIOUSLY...THE MAIN CONCERN TODAY IS THE FLOOD
POTENTIAL.

ON A FINAL NOTE...WE WILL CONTINUE TO SEE THE THREAT OF WET SNOW
ABOVE 11000 FEET.  WEB CAMS YESTERDAY MORNING INDICATED A DUSTING OF
SNOW ATOP PIKES PEAK AND KCCU (JUST NORTH OF LAKE COUNTY) HAS BEEN
INDICATING SNOW WITH TEMPS IN THE MID 30S DURING THE NIGHT.
SO...SOME SNOW IS LIKELY OCCURRING ACROSS THE HIGHER TERRAIN. LW

.LONG TERM...
(SUNDAY THROUGH FRIDAY)

METEOROLOGICAL ISSUES FOR THE LONGER TERM CYCLE INCLUDE THE
POTENTIAL FOR HEAVY PRECIPITATION AS WELL AND CONTINUED UNSEASONABLY
COOL MAXIMUM TEMPERATURES...ESPECIALLY OVER EASTERN SECTIONS ON
SUNDAY AS WELL AS THE POTENTIAL FOR SOME GENERALLY LIGHT HIGHER
ELEVATION SNOW.

LONGER TERM MODELS SUGGEST THAT CLOSED UPPER LOW OVER CENTRAL
COLORADO AT 12Z SUNDAY SHIFTS INTO FAR SOUTHEAST COLORADO BY 12Z
MONDAY BEFORE PUSHING SOUTHEAST OF OUR CWFA BY 12Z TUESDAY.

SURFACE HIGH CENTERED OVER NORTHEASTERN KANSAS SUNDAY MORNING
SHIFTS INTO THE UPPER MIDWEST BY LATER TUESDAY WITH EASTERN
COLORADO LEE SIDE TROUGH IN PLACE FROM WEDNESDAY INTO FRIDAY OF
NEXT WEEK. THE MOIST AND COOL UPSLOPE FLOW IS EXPECTED TO PERSIST
INTO SUNDAY AND WHEN COMBINED WITH PRECIPITABLE WATERS OF 0.60 TO
1.25 FROM THE I-25 CORRIDOR TO THE KANSAS BORDER AND HEALTHY UPPER
LIFT AS PROJECTED BY THE 300-200MB PVU FORECAST...WILL CONTINUE
WITH THE INHERITED FLASH FLOOD WATCH INTO SUNDAY EVENING AS
LOCALLY HEAVY RAINFALL CONTINUES TO REMAIN A CONCERN.

AS THE CLOSED UPPER LOW MOVES AWAY FROM THE CWFA NEXT WEEK AND
SURFACE LEE TROUGHING SETS UP OVER THE EASTERN PLAINS...PROJECT
THAT NEXT WEEK WILL NOTE INCREASING TEMPERATURES TO NEAR TO A
CATEGORY OR TWO ABOVE CLIMATOLOGICAL AVERAGES AS WELL AS DECREASED
PRECIPITATION CHANCES...ESPECIALLY WHEN COMPARED WITH THIS PAST
THURSDAY THROUGH SATURDAY EVENT. ALSO...GRADIENT WINDS EXPECTED TO
REMAIN WELL-BEHAVED DURING THE LONG TERM. FINALLY...WILL CONTINUE
TO PAINT SOME GENERALLY LIGHT ACCUMULATING SNOW OVER THE HIGHER
MOUNTAINS AT TIMES ON SUNDAY.

&&

.AVIATION...

NUMEROUS SHOWERS AND THUNDERSTORMS WILL CONTINUE ACROSS THE FORECAST
AREA THROUGH TONIGHT.  A FEW SEVERE STORMS ARE POSSIBLE OVER THE
EASTERN PLAINS THIS AFTERNOON AND EVENING.  SEE ABOVE DISCUSSION FOR
SEVERE THREATS.  FREQUENT MVFR/IFR CIGS AND VSBYS DUE TO LOW
CLOUDS...SHOWERS AND THUNDERSTORMS.  ALSO...AREAS OF LIFR CIGS AND
VSBYS DUE TO HEAVY PRECIPITATION AND CLOUDS.  SNOW SHOWERS PRODUCING
IFR/LIFR CIGS AND VSBYS WILL BE POSSIBLE IN THE MOUNTAINS ABOVE 11K
THROUGH TONIGHT. LW

.PUB WATCHES/WARNINGS/ADVISORIES...
FLASH FLOOD WATCH THROUGH SUNDAY EVENING FOR COZ072>089-093>099.

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

.DAY ONE...TODAY AND TONIGHT

NUMEROUS SHOWERS AND THUNDERSTORMS WILL CONTINUE OVER SOUTHERN
COLORADO TODAY.  THE MAIN CONCERN WITH THESE STORMS WILL BE THE
FLOOD POTENTIAL.  IN MOST AREAS...THE MAIN PROBLEM WILL BE URBAN AND
SMALL STREAM FLOODING.  HOWEVER...A FEW AREAS COULD SEE TRUE FLASH
FLOODING GIVEN THE ALREADY SATURATED SOILS AND THE AMOUNT OF
MOISTURE IN THE AIR.

DURING THE AFTERNOON AND EVENING HOURS...A FEW THUNDERSTORMS ON THE
PLAINS COULD BECOME SEVERE PRODUCING HAIL UP TO 1 INCH IN
DIAMETER...WIND GUSTS TO 60 MPH...HEAVY RAIN...AND FREQUENT
LIGHTNING.

ELSEWHERE...THE MAIN THREATS FROM STORMS TODAY WILL BE HAIL UP TO
1/2 INCH IN DIAMETER...HEAVY RAIN...WIND GUSTS TO 50 MPH...AND
LIGHTNING.

SOME WET SNOW CLOUD FALL IN THE MOUNTAINS TODAY AND TONIGHT.  THIS
IS MOST LIKELY TO OCCUR ACROSS THE SAWATCH RANGE...THE MOSQUITO
RANGE AND PIKES PEAK.  HOWEVER...ALL OF THE MOUNTAINS WILL BE
SUSCEPTIBLE.  ELEVATIONS ABOVE 11000 FEET COULD SEE A FEW INCHES OF
WET SNOW ACCUMULATION BY SUNRISE SUNDAY.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS...SOME PRODUCING
HEAVY RAINFALL WHICH WILL BE CAPABLE OF PRODUCING FLASH FLOODING
ARE EXPECTED SUNDAY AND SUNDAY NIGHT. ISOLATED TO SCATTERED
THUNDERSTORMS ARE THEN ANTICIPATED MONDAY WITH ISOLATED MAINLY
MOUNTAIN THUNDERSTORM PROJECTED FROM TUESDAY INTO FRIDAY.

THE PRIMARY METEOROLOGICAL THREATS FROM THE THUNDERSTORMS THROUGH
THE PERIOD WILL BE HEAVY RAIN...LIGHTNING...SMALL HAIL AND WIND
GUSTS TO 40 MPH AT TIMES.

IN ADDITION...LIGHT ACCUMULATING SNOW MAY BE NOTED OVER THE HIGHER
MOUNTAINS SUNDAY AND SUNDAY NIGHT.

.SPOTTER INFORMATION STATEMENT...

WEATHER CONDITIONS THAT MEET REPORTING CRITERIA FOR SPOTTERS WILL BE
POSSIBLE JUST ABOUT ANYWHERE IN SOUTHERN COLORADO THROUGH TONIGHT.
