AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PUEBLO CO
548 AM MDT THU MAY 21 2009

.SHORT TERM...

(TODAY AND TONIGHT)

...COOL AND MOIST REGIME SETTLES IN OVER SOUTHERN COLORADO TODAY...

THINGS ARE STARTING TO TAKE SHAPE FOR A COOLER AND WETTER PATTERN.
THE INITIAL BLAST OF COOLER AND WETTER AIR HAS PUSHED THROUGH MOST
OF PUEBLO COUNTY...HEADED QUICKLY SOUTH ALONG THE SOUTHERN FRONT
RANGES.  THE REAL CORE OF THE COLD AIR IS STILL A WAYS OFF TO THE
NORTH...MOVING THROUGH THE COMMUNITIES JUST TO THE NORTH OF GREELEY
AND FORT COLLINS.  THIS AIR IS FORECAST TO ACCELERATE SOUTHWARD
PRETTY QUICKLY OVER THE NEXT FEW HOURS...CROSSING MOST OF EL PASO
COUNTY BY 9AM AND REACHING THE SOUTHERN BORDER AREAS BY NOON.  THE
FRONTAL PASSAGE WILL BE MARKED BY COOLER AIR...GUSTY NORTH TO
NORTHEAST WINDS...INCREASING CLOUDS...SCATTERED SHOWERS...AND
POSSIBLY A FEW THUNDERSTORMS.  DURING THE AFTERNOON...WINDS WILL
TURN STRONGLY UPSLOPE...WITH SHOWERS AND THUNDERSTORMS MAINLY OVER
THE MOUNTAINS.. HIGH VALLEYS AND PLAINS WEST OF THE I-25
CORRIDOR...AND ALSO ALONG THE PALMER AND RATON RIDGES.  IT LOOKS
LIKE THE AIR WITH THIS INITIAL BLAST MAY BE TOO STABLE FOR MUCH
PRECIPITATION OUT ACROSS THE PLAINS FARTHER EAST FOR TODAY.

TONIGHT...ALL THE MODELS INSIST THAT SHOWER COVERAGE WILL BE FAIRLY
WIDESPREAD DURING THE EVENING HOURS...ALONG WITH SOME LOCALLY HEAVY
RAINFALL POSSIBLE FROM EMBEDDED THUNDERSTORMS.  CANT REALLY ARGUE
WITH THIS TOO MUCH AS THE CONCEPTUAL MODEL SEEMS TO BE THERE.  THERE
IS GOOD SUPPORT FOR THIS IN THE LOW AND MID LEVELS WITH DEEP UPSLOPE
FLOW IN PLACE.  WINDS ARE PROGGED TO BE FROM THE SOUTHEAST AT 5-20
MPH NEAR THE 10000 FOOT LEVEL.  THE SURFACE MOISTURE THAT WE ARE SO
OFTEN LACKING APPEARS ADEQUATE WITH SURFACE DEWPOINTS FORECAST TO BE
IN THE MID 40S TO LOWER 50S DURING THE EVENING HOURS.  THE UPPER
LOW OVER ARIZONA WILL PROVIDE SOME WEAK BUT PERSISTENT BROAD SCALE
ASCENT...AS WELL AS AN INFLUX OF SUBTROPICAL MOISTURE.  PLUS...THE
SYSTEM TAKES ON A STRONG NEGATIVE TILT WHICH IS CONCEPTUALLY
CONSISTENT WITH UPPER LEVEL DIVERGENCE OVER COLORADO WHICH IS...IN
TURN...CONSISTENT WITH LIFTING MOTIONS OVER THE AREA.  SO...IT IS
POSSIBLE THAT ALL COULD COME TOGETHER FOR SOME FAIRLY GOOD SHOWER
COVERAGE ACROSS SOUTHERN COLORADO THIS EVENING...INCLUDING A FEW
THUNDERSTORMS PRODUCING LOCALLY HEAVY RAINFALL.  ACTIVITY SHOULD
STILL TEND TO DIE DOWN BY MIDNIGHT...ALTHOUGH THE MOISTURE WILL
REMAIN IN PLACE FOR THE NEXT DAY.  IN FACT...SURFACE MOISTURE LOOKS
PRETTY RICH AND SURFACE WINDS LOOK PRETTY LIGHT TONIGHT SO COULD SEE
SOME AREAS OF FOG BY FRIDAY MORNING. LW

.LONG TERM...
(FRIDAY THROUGH WEDNESDAY)

UNSETTLED MILD CONDITIONS ANTICIPATED DURING THE LONGER TERM AS
ADEQUATE ATMOSPHERIC MOISTURES COMBINES WITH GENERALLY EAST TO
SOUTHEAST LOW LEVEL FLOW EASTERN SECTIONS(ALTHOUGH ANOTHER HEALTHY
NORTHERLY SURGE WILL BE POSSIBLE BY NEXT TUESDAY/TUESDAY EVENING)
AND OCCASIONAL SHORT WAVES.

LATEST LONGER TERM COMPUTER SIMULATIONS INDICATE THAT MONDAY
THROUGH NEXT WEDNESDAY AND POSSIBLY EVEN LATER SUNDAY WILL HAVE A
HIGHER PROBABILITY OF AT LEAST ISOLATED STRONG TO POSSIBLY SEVERE
CONVECTION THANKS TO SOMEWHAT INCREASED MAXIMUM TEMPERATURES AS
COMPARED TO THE FRIDAY THROUGH EARLY SUNDAY TIME-FRAME AS WELL AS
MORE FAVORABLE UPPER SUPPORT AS NOTED BY LATEST PVU PROJECTIONS.
AT THIS TIME WILL CONTINUE TO PAINT GENERALLY ISOLATED TO SCATTERED
POPS DURING THE MAJORITY OF THE LONG TERM.

MAXIMUM TEMPERATURES PROJECTED TO RUN NEAR TO SLIGHTLY BELOW LATE
MAY CLIMATOLOGICAL AVERAGES FROM FRIDAY INTO SUNDAY...WITH NEAR TO
SLIGHTLY ABOVE LATE MAY CLIMATOLOGICAL AVERAGE TEMPERATURES
ANTICIPATED FROM MONDAY INTO NEXT WEDNESDAY.

&&

.AVIATION...

GENERALLY VFR CONDITIONS AT ALL THREE TAF SITES THIS
MORNING WILL GRADUALLY DECLINE LATER THIS MORNING THROUGH THE
AFTERNOON...  SETTLING INTO THE MVFR RANGE BY THIS EVENING AS
WIDESPREAD CLOUDS AND SCATTERED PRECIPITATION SETTLE IN.  THIS IS
GENERALLY TRUE FOR ALL AREAS ALONG AND WEST OF THE I-25 CORRIDOR.
CONDITIONS FARTHER EAST WILL GENERALLY BE BETTER...DUE TO LESS CLOUD
COVER AND PRECIPITATION.  HOWEVER...EVEN THESE AREAS CAN EXPECT
ISOLATED TO SCATTERED MVFR CONDITIONS DUE TO SHOWERS BY THIS
EVENING. LW

.PUB WATCHES/WARNINGS/ADVISORIES...
NONE.
