AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PUEBLO CO
441 AM MDT WED APR 21 2010

.SHORT TERM...
(TODAY AND TONIGHT)

...STRONG STORMS OVER THE SOUTHEAST PLAINS THIS AFTERNOON...

CURRENTLY...SHOWERS OVER THE FAR EASTERN PLAINS THIS MORNING HAVE
ALL BUT DISSIPATED WHILE FOG AND LOW STRATUS HAVE DEVELOPED OVER THE
ARKANSAS RIVER VALLEY AND NORTHERN I-25 CORRIDOR.  OBSERVATIONS AND
WEBCAMS FROM AROUND THE COLORADO SPRINGS AREA INDICATE VISIBILITIES
HAVE DROPPED TO NEAR A 1/4 MILE THIS MORNING AND WILL REMAIN DENSE
THROUGH 13Z.  OTHER AREAS ALONG THE ARKANSAS RIVER VALLEY INCLUDING
THE PUEBLO AREA ARE SEEING AREAS OF FOG THIS MORNING AND WILL
CONTINUE TO DO SO THROUGH 12Z WITH VISIBILITIES GENERALLY AROUND 3
MILES.

FOCUS TURNS TO THE POTENTIAL FOR STRONG THUNDERSTORMS FOR THIS
AFTERNOON AND EVENING.  A SHORTWAVE TROUGH WILL ROTATE AROUND A
STRONG AREA OF LOW PRESSURE OVER THE GREAT BASIN AND EJECT ACROSS
SOUTHERN COLORADO BY LATE THIS AFTERNOON.  SOUTHEASTERLY FLOW ACROSS
THE PLAINS WILL INCREASE THROUGH THE MORNING HOURS HELPING MAINTAIN
LOW LEVEL MOISTURE WITH DEW PTS IN THE UPPER 40S TO LOW 50S.  EXPECT
CLOUDS AND FOG TO DISSIPATE THROUGH 14Z WITH SUN HELPING TO
DESTABILIZE THE PLAINS THROUGH THIS AFTERNOON.  MODELS ALL
GENERATING CAPE VALUES NEAR 1500 J/KG OVER THE PLAINS WITH LI VALUES
NEAR -4 AND VERY LITTLE CAP TO OVERCOME BY 18-21Z.  SHEAR STARTS OUT
MARGINAL THIS MORNING INCREASING BY LATE AFTERNOON AS A 700 MB SPEED
MAX ROTATES INTO SOUTHERN COLORADO WITH 0-6KM SHEAR APPROACHING
35-40 KTS.  WRF AND NAM MOISTURE ANALYSIS ALSO BRING A SURGE OF
MOISTURE NORTHWARD OUT OF THE TX PANHANDLE INTO BACA COUNTY BY LATE
AFTERNOON AS WELL.  MOST OF THE INGREDIENTS ARE THERE FOR STRONG
THUNDERSTORMS PARTICULARLY SOUTH OF HIGHWAY 50 AND EAST OF I-25 FROM
21Z-03Z THIS AFTERNOON AND EVENING.  THERE WILL ALSO BE THE
POSSIBILITY OF A SEVERE STORM OR TWO OVER EASTERN LAS ANIMAS AND
BACA COUNTIES LATE THIS AFTERNOON.  ELSEWHERE...CONVECTION WILL
DEVELOP OVER THE EASTERN MOUNTAINS BY EARLY AFTERNOON AND SPREAD
EASTWARD INTO THE I-25 CORRIDOR AND PALMER DIVIDE THROUGH THE
EVENING.  THESE STORMS WILL HAVE THE POTENTIAL TO PRODUCE HEAVY
RAINFALL...SMALL HAIL AND GUSTY OUTFLOW WINDS AS THEY MOVE OFF THE
HIGHER TERRAIN TO THE WEST.  WITH THE BEST DYNAMICS AND INSTABILITY
TO THE EAST OF THE I-25 CORRIDOR...EXPECT THESE THUNDERSTORMS TO
REMAIN BELOW SEVERE LIMITS WITH ONE OR TWO BECOMING STRONG.

MODELS DIFFER ON TIMING OF THE UPPER LOW OVER THE GREAT BASIN FOR
TONIGHT.  GFS IS MORE PROGRESSIVE THAN THE NAM WITH ROTATING THE
FIRST IN A SERIES OF STRONG WAVES INTO WESTERN COLORADO TONIGHT.
TRENDED WITH THE NAM WHICH HAS SUPPORT FROM THE ECMWF AND SREF IN
REGARDS TO TIMING.  COLDER AIR WILL START TO WORK INTO WESTERN
COLORADO BY TOMORROW MORNING WITH SNOW LEVELS LOWERING THROUGH THE
NIGHT.  MOIST SOUTHWESTERLY FLOW SHOULD KEEP PRECIPITATION GOING
ALONG THE SOUTH AND WEST FACING SLOPES THROUGH TOMORROW MORNING
WHERE AN INCH OR TWO OF SNOWFALL WILL BE POSSIBLE ABOVE 10 KFT.
STRONG THUNDERSTORMS WILL PERSIST OVER THE FAR SOUTHEASTERN PLAINS
THROUGH 03Z BEFORE DECREASING IN INTENSITY.  SHOWERS AND
THUNDERSTORMS WILL BEGIN TO DISSIPATE ACROSS THE PLAINS BY 06Z.
SOUTHEASTERLY FLOW WILL CONTINUE THROUGH THE OVER HOURS WITH MODELS
CONTINUING TO ADVECT MOISTURE INTO THE PLAINS WITH DEW PTS RISING
INTO THE LOWER 50S.  FOG AND LOW STRATUS WILL ONCE AGAIN BE POSSIBLE
ALONG THE ARKANSAS RIVER VALLEY AND EL PASO COUNTY BY TOMORROW
MORNING.  MOZLEY

.LONG TERM...
(THURSDAY THROUGH TUESDAY)

SLOW MOVING UPR LOW WL AFFECT THE AREA THU THRU AT LEAST SAT. THU
THE UPR LOW WL BE CENTERED OVR SRN NV WITH A SHRTWV TROF ROTATING
AROUND THE LOW OVR OUR CWA. COULD SEE SOME LINGERING SHOWERS
DURING THE MORNING HRS IN SOME AREAS. ALSO...A LOT OF LOW LEVEL
MSTR OVR THE MAJORITY OF THE SERN PLAINS SHOULD RESULT IN A LOT OF
LOW CLOUDS AND POSSIBLY SOME FOG. FOR THE AFTERNOON THERE ARE MODEL
DIFFERENCES WITH REGARDS TO LOW LEVEL MSTR ACRS THE SERN CO
PLAINS. BOTH THE GFS AND NAM SHOW SOME LOW LEVEL DRYING OVR THE
SRN PORTIONS OF THE SERN PLAINS...BUT THE GFS IS THE DRIEST. BY
MID AFTERNOON THE NAM HAS UPR 30S TO LOWER 40S FOR DEW PTS OVR
PUEBLO AND EL PASO COUNTIES AND OVR THE KANSAS BORDER
COUNTIES...DECREASING SOME TOWARD 00Z FRI...WITH LOWER 30S OVR LAS
ANIMAS COUNTY. THE GFS HAS 20S FOR DEW POINTS ACRS THE SERN
PLAINS. THUS THE GFS HAS ALL THE HIGH CAPE VALUES IN KS. WITH THE
NAM ALSO DRYING THE LOWER LEVEL BY LATE AFTERNOON SO IT TOO PUSHES
THE HIGHER CAPE VALUES MOSTLY INTO KS. DURING THE MID TO LATE
AFTERNOON HRS THE BEST CHANCES FOR ANY SEVERE WEATHER SHOULD
MAINLY OVER EL PASO AND PUEBLO COUNTIES AND MAYBE KIOWA AND
PROWERS COUNTIES. IT ALL DEPENDS ON HOW FAST THE DRYER LOW LEVEL
AIR PUSHES EAST. SHEAR VALUES ACRS THE SERN PLAINS THU AFTERNOON
ARE EXPECTED TO BE AROUND 50 KTS SO COULD GET SOME STORMS
ROTATING.

THU NIGHT AND EARLY FRI THE UPR LOW BECOMES AN ELONGATED AREA
STRETCHING FROM SRN WY TO SWRN AZ...WHICH MOVES EAST OF THE AREA
THRU THE DAY FRI. FRI NIGHT THE LOW IS CENTERED OVR ERN CO ON THE
NAM AND ON THE GFS BECOMES CENTERED OVER SOUTH CENTRAL NE. THRU
THIS PERIOD THE WEATHER ACRS THE FORECAST AREA WL REMAIN UNSETTLED
WITH SHOWERS AND THUNDERSTORMS AND COOLER TEMPS. SAT THE UPR LOW
MOVES FARTHER EAST OVR ERN KS AND NE...BUT LINGERING MSTR AND WRAP
AROUND PCPN WL KEEP SHOWERS OVR THE FORECAST AREA.

SUN THAT SYSTEM WILL MOVE OUT OF THE AREA AND A NEW UPR LOW IS
EXPECTED TO BE OVR MT. LINGERING MSTR OVR THE CWA AND DAYTIME
HEATING SHOULD LEAD TO THE CHANCE FOR SOME AFTERNOON AND EVENING
SHOWERS...MAINLY OVR THE HIGHER TERRAIN. ON MON THAT UPR LOW OVR
MT IS FORECAST TO MOVE SOUTH INTO NERN CO ON THE ECMWF...BUT ON
THE GFS IS FORECAST TO EXTEND FROM CENTRAL SD TO CENTRAL MT AND
SENDS A FRONT INTO ERN CO. THE ECMWF HAS WIDESPREAD PCPN OVR THE
SERN PLAINS...WHILE THE GFS HAS LITTLE PCPN. THE ECMWF AND GFS
MOVE THIS SYSTEM OUT OF THE FORECAST AREA TUE...WITH JUST THE
POSSIBILITY OF SOME LIGHT PCPN. WITH THE UNCERTAINTIES...WL NOT
MAKE FEW IF ANY CHANGES TO THE POPS DURING THIS TIME FRAME.

&&

.AVIATION...

KCOS...FOG HAS DEVELOPED EARLY THIS MORNING REDUCING VISIBILITIES TO
1/4 MILE AND VV001 CONDITIONS.  THESE CONDITIONS WILL PERSIST
THROUGH 13Z WITH IMPROVEMENT TO VFR CONDITIONS BY 15Z.
THUNDERSTORMS WILL ONCE AGAIN BE POSSIBLE AT THE TERMINAL THIS
AFTERNOON AND EVENING.  THE MOST LIKELY TIME FRAME FOR THUNDERSTORMS
WILL BE 20Z THROUGH 03Z WITH HEAVY RAINFALL AND GUSTY ERRATIC
OUTFLOW WINDS BEING THE MAIN IMPACTS.  EXPECT IFR CONDITIONS IN ANY
HEAVIER CORES THAT PASS OVER THE TAF SITE.  FOG AND LOW STRATUS WILL
ONCE AGAIN BE POSSIBLE OVERNIGHT WITH MVFR TO IFR CONDITIONS BY
TOMORROW MORNING.

KPUB...FOG AND LOW STRATUS HAVE DEVELOPED EARLY THIS MORNING WITH
MVFR TO IFR CONDITIONS.  FOG NOT AS DENSE AS KCOS AND WILL DISSIPATE
BY 12Z WITH VFR CONDITIONS THROUGH THIS AFTERNOON.  SHOWERS AND
THUNDERSTORMS WILL DEVELOP THIS AFTERNOON AND HAVE THE POTENTIAL TO
IMPACT THE TERMINAL FROM 22Z THROUGH 03Z.  THE MAIN IMPACTS WILL BE
HEAVY RAINFALL AND GUSTY ERRATIC OUTFLOW WINDS.  EXPECT IFR
CONDITIONS IN ANY HEAVIER CORES THAT PASS THE TAF SITE.  FOG AND LOW
STRATUS WILL BE POSSIBLE OVERNIGHT WITH MVFR TO IFR CONDITIONS BY
TOMORROW MORNING.

KALS...EXPECT VFR CONDITIONS TO PREVAIL THROUGH THIS AFTERNOON.
SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE LATE THIS AFTERNOON AND
EVENING AT THE TAF SITE BUT CONFIDENCE IS LOW IN OCCURRENCE AT THIS
TIME.  ANY SHOWERS OR THUNDERSTORMS THAT IMPACT THE TERMINAL WILL
BRING LOWERED VIS AND CIGS AS THEY PASS.  MOZLEY
