AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PUEBLO CO
259 PM MDT MON SEP 24 2007

.SHORT TERM...
(TONIGHT AND TUESDAY)

MAIN CONCERNS ARE EXPECTED FREEZE TONIGHT IN THE SAN LUIS
VALLEY...AND PCPN CHANCES THIS EVENING.

AS THE MODELS WERE FORECASTING...THE MAIN ENERGY AND ACTIVITY WITH
THIS PASSING UPR TROF...HAS BEEN TO THE NORTH OF THE FORECAST AREA
TODAY.  WE HAVE SEEN 3 DISTINCT BOUNDARIES MOVE INTO EL PASO COUNTY
TODAY...AND AS OF 230 PM A BOUNDARY LIES FROM JUST SOUTH OF COLORADO
SPRINGS...INTO CENTRAL CROWLEY COUNTY AND ACROSS KIOWA COUNTY. SOUTH
OF THIS FRONT DEW POINTS ARE IN THE 20S...WHILE NORTH OF THE FRONT
DEW POINTS ARE IN THE MID 30S TO LOWER 40S.  THE NAM CONTINUES TO
SHOW SOME PCPN THIS EVENING OVR THE CENTRAL MTS AND EL PASO COUNTY.
WHILE THE GFS IS DRY. WITH A LITTLE MORE LOW LEVEL MSTR AND A FAIRLY
GOOD UPSLOPE FLOW OVR EL PASO COUNTY...THIS AREA MAY SEE SOME
SHOWERS/TSTMS DEVELOPMENT OVR THE AREA INCLUDING TELLER COUNTY.
WILL ALSO KEEP SOME PCPN OVR THE CENTRAL MTS.  THE NAM HAS THE FRONT
PUSHING FARTHER SOUTH THIS EVENING...REACHING THE SRN CO BORDER
BETWEEN 03Z AND 06Z. PCPN CHANCES DO NOT LOOK THAT PROMISING
ELSEWHERE...BUT WE COULD SEE SOME PCPN DEVELOP ALONG AND BEHIND THE
FRONTAL BOUNDARY OVR OTHER PORTIONS OF THE SERN PLAINS AND AM
RELUCTANT TO REMOVE POPS. BUT WL TRIM BACK POPS IN AREA AND COVERAGE
OVR THE SERN PLAINS.  THE 18Z RUN OF THE NAM IS NOW SHOWING SOME
PCPN ALONG THE SERN FOOTHILLS AFTER MIDNIGHT.  NOT SO SURE THIS WL
HAPPEN BUT AFTER THE FRONTAL PASSAGE THE LOWER LEVEL MSTR DOES
INCREASE AND SOME LOW CLOUDS...AND MAYBE A LITTLE DRIZZLE...ARE MORE
LIKELY.  IN THE SAN LUIS VALLEY TONIGHT THERE SHOULD NOT BE MUCH FOR
CLOUD COVER...AND WITH A COOLER AIR MASS BEING OVR THE AREA
TONIGHT...TEMPS SHOULD BE ABLE TO DROP INTO THE MID 20S TO AROUND
30. THUS A HARD FREEZE CAN BE EXPECTED IN MANY AREAS OF THE SAN LUIS
VALLEY...AND THE WATCH WILL BE UPGRADED TO A FREEZE WARNING.

ON TUESDAY THE UPR TROF WL BE EAST OF THE AREA WITH WESTERLY FLOW
ALOFT...BUT THERE WL STILL BE SOME LOW LEVEL UPSLOPE OVR THE SERN
PLAINS.  THE 18Z NAM KEEPS SOME LOW AND MID LEVEL MSTR OVR PORTIONS
OF THE SERN PLAINS INTO THE AFTERNOON HOURS.  THERE SHOULD BE A LOT
OF LOW CLOUDS OVR PORTIONS OF THE SERN PLAINS IN THE MORNING...BUT
SOME OF THESE MAY HANG ON INTO THE AFTERNOON IF THE NAM IS CORRECT.
WL HAVE TO ADJUST THE SKY GRIDS TO ACCOUNT FOR THIS POSSIBILITY OF
CLOUDS.

.LONG TERM...
(TUESDAY NIGHT THROUGH MONDAY)

TUESDAY NIGHT AND WEDNESDAY...WEST TO NORTHWEST FLOW ALOFT WILL
CONTINUE AS ANOTHER SHORTWAVE MOVES ACROSS THE N ROCKIES TUE NIGHT
AND WED. THIS IS EXPECTED TO DROP A DRY NORTHERLY SURGE DOWN ACROSS
COLORADO WED...PRODUCING MOSTLY SUNNY SKIES WITH MAX TEMPS IN THE
70S TO NEAR 80. CLEARING SKIES AND LIGHTER WINDS SHOULD DROP MIN
TEMPS BOTH TUE AND WED NIGHTS BELOW FREEZING FOR THE HIGHER VALLEYS.

THURSDAY AND FRIDAY...AMPLIFYING TROUGH OVER THE WEST COAST IS
FORECAST TO INCREASE THE SW FLOW ALOFT ACROSS THE 4 CORNERS REGION
BEGINNING THU...AS WELL AS USHER IN WARMER MAX TEMPS FOR BOTH DAYS.
CURRENTLY FRIDAY LOOKS TO BE THE WARMEST DAY OF THE EXTENDED
FORECAST. BOTH NAM AND GFS MODELS INDICATE THAT PCPN WILL BE LURKING
NEAR THE SE CORNER OF THE STATE FOR THE END OF THE WEEK...AND A
QUICK LOOK AT FORECAST MSL FIELDS SHOW A TROUGH OVER THIS AREA SO
THERE MAY BE SOME TRUTH TO THIS. UPPER JET LAYS ACROSS THE STATE ON
FRI AS WELL SO INCREASING WINDS ARE EXPECTED...BUT CWA WILL NOT BE
IN THE FAVORABLE LF QUAD. KEPT CWA DRY THROUGH FRI MORN...THEN BROAD
BRUSHED SOME ISOLATED POPS FOR THE CWA FRI EVE. THIS WILL HAVE TO BE
REVISED IN THE NEXT DAY OR SO.

SATURDAY THROUGH MONDAY...THE TROUGH OVER THE PAC NW INTENSIFIES BUT
IS FORECAST TO STAY ACROSS THE NORTHERN PORTIONS OF THE
U.S...MEANING BRISK WINDS BUT PROBABLY NOT TOO MUCH PCPN FOR THE
CWA. INTRODUCED SOME ISOLATED POPS FOR THE CENTRAL AND SW MTS SAT
AFTN JUST IN CASE THIS TROUGH DROPS A BIT FURTHER SOUTH...OTHERWISE
LEFT THE AREA DRY. CURRENT GRID TRENDS SHOW A WARM DAY SAT...COOLER
ON SUN IN RESPONSE TO A COOL SURGE MOVING THROUGH THE AREA DUE TO
THE DISTURBANCE TO THE NORTH...THEN REBOUNDING TEMPS AGAIN ON MON.
THIS FAR OUT...TIMING AND LOCATION OF THIS WEATHER FEATURE WILL
UNDOUBTEDLY CHANGE. IN ADDITION...SAW NO NEED TO CONTINUE WITH
SINGLE DIGIT POPS THIS FAR OUT SO WENT WITH NIL POP GRIDS. MOORE

&&

.AVIATION...
KALS AREA SHOULD SEE VFR CONDITIONS TONIGHT AND TUESDAY. SOME LOW
CLOUDS WL PROBABLY DEVELOP OVR MUCH OF THE SERN PLAINS TONIGHT
WITH MVFR CIGS...MAINLY AFTER MIDNIGHT...BUT COULD SET IN A BIT
EARLIER OVR PORTIONS OF EL PASO COUNTY.
