AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PUEBLO CO
334 PM MDT FRI AUG 29 2008

.SHORT TERM...
...A FEW STRONG TO SEVERE THUNDERSTORMS THIS EVENING I-25 CORRIDOR
WESTWARD...

POTENTIAL FOR SOME STRONG TO SEVERE PULSE TYPE STORMS THIS EVENING.
CELL EAST OF RATON SHOT A 50 DBZ CORE UP TO 43,000 FEET MSL EARLIER
THIS AFTERNOON.  ANOTHER CELL DROPPED PENNY SIZE HAIL NEAR RYE A
LITTLE AFTER 3 PM.  POTENTIAL FOR MORE BIG PULSE STORMS LIKE THIS
THROUGH THE EVENING...WITH PRIMARY THREATS...PEA SIZE HAIL...WIND
GUSTS TO 40 MPH...LIGHTNING AND HEAVY RAIN.  ONE OR TWO STORMS ALONG
AND WEST OF THE I-25 CORRIDOR COULD BECOME SEVERE...PRODUCING PENNY
TO QUARTER SIZE HAIL AND WIND GUSTS TO 60 MPH.

TONIGHTS STORMS ARE DEVELOPING BENEATH A CYCLONIC SHEAR AXIS DRAPED
OVER SOUTHERN COLORADO FROM WEST TO EAST.  AXIS SHOWS UP PRETTY WELL
IN WATER VAPOR IMAGERY WITH GOOD MID LEVEL MOISTURE SOUTH OF THE
AXIS...ACROSS SOUTHERN COLORADO...BUT MUCH DRIER AIR TO THE NORTH.
SURFACE MOISTURE LOOKS GOOD...TOO...WITH PLAINS DEW POINTS IN THE
MID 50S TO LOWER 60S...AND MOST MOUNTAIN/HIGH VALLEY DEWS IN THE 40S.
EXCEPTION APPEARS TO BE OVER LAKE COUNTY AND THE HIGHER TERRAIN OF
CHAFFEE COUNTY...WHERE THE DRIER AIR NORTH OF THE SHEAR AXIS APPEARS
TO BE MIXING TO THE SURFACE.  IN THESE AREAS...DEWS ARE ONLY IN THE
TEENS AND 20S.  WOULD NOT EXPECT STORMS TO BE AS STRONG IN THESE
AREAS.

TONIGHT...WITH DEWS SO HIGH...AND LIGHT OR WEAKLY UPSLOPE
WINDS...COULD DEVELOP SOME PATCHY FOG/STRATUS AS IN PREVIOUS
MORNINGS.  STORM ACTIVITY SHOULD MOSTLY BE DONE BY MIDNIGHT.

FOR SATURDAY...LOOKS WARMER AND DRIER OVERALL.  UPPER SHEAR AXIS/
DISTURBANCE THAT IS AFFECTING AREA THIS EVENING MOVES OFF TO THE
NORTHEAST...REPLACED BY WARMER/DRIER SOUTHERLY FLOW.  THIS SHOULD
INCREASE TEMPERATURES SLIGHTLY AND DECREASE THUNDERSTORM COVERAGE
SLIGHTLY.  WILL CONFINE THE AREA FOR SCATTERED THUNDERSTORM COVERAGE
MAINLY TO THE MOUNTAINS...WITH ISOLATED COVERAGE ELSEWHERE. WILL
BOOST TEMPERATURES IN RESPONSE TO THE WARMING/DRYING WINDS.  WILL
ALSO BOOST WIND SPEEDS ACROSS THE EASTERN PLAINS SATURDAY...AS
CONDITIONS WILL GET A BIT BREEZY DURING THE AFTERNOON...ESPECIALLY
OVER THE FAR EAST. LW

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

AS MENTIONED IN LAST NIGHTS AFD...MAIN CHALLENGE IN THE EXTENDED
WILL BE THE EFFECTS OF A TROUGH AND CUT-OFF LOW THAT WILL MOVE
INTO THE GRAT BASIN DURING THE LATTER HALF OF THE WEEKEND.

LATEST GFS GUIDANCE HAS REVERTED TO EARLIER PROGS AND IS IN BETTER
AGREEMENT WITH THE ECMWF...WHICH LIFTS THE UPPER LOW INTO NRN WY OR
MT BY EARLY NEXT WEEK. THE MORE NORTHERN SOLUTION PROLONGS AND
LESSENS ANY ADVANCE OF DEEP MOISTURE TO THE SERN CO PLAINS. PLAINS
LOOK PRETTY DRY SAT EVE...AND CAPE IS GENERALLY ABSENT EXCEPT OVR
NERN CO. HAVE KEPT MENTION OF STORMS OUT OF THE PLAINS DURING THE
EVE...IN AGREEMENT WITH STATISTICAL GUIDANCE THAT KEEPS 6 H POPS
BELOW 5 PERCENT. ERN SECTIONS SHOULD STAY PRETTY CLEAR
OVERNIGHT...WHILE WRN ZONES WILL SEE INCREASING CHANCES OF
CONVECTION AS THE UPPER LOW AND SRN MOISTURE FETCH BEGINS MOVING
EWD. BY SUN AFTERNOON...SAN JUANS AND LA GARITAS WILL SEE A GOOD
CHANCE OF SOME CONVECTION...WHILE ERN PLAINS WILL REMAIN FAIRLY
DRY. THE LEE TROUGH WILL STRENGTHEN CONSIDERABLY BY
AFTERNOON...WITH SFCE WINDS REACTING AND SOME GUSTY CONDITIONS OVR
THE PLAINS BY AFTERNOON AND EVE. FIRE WX ISSUES MAY BECOME A CONCERN
IF DEWPTS END UP A LITTLE LOWER THAN CURRENTLY ANTICIPATED.

MON...ACCORDING TO THE MESOSCALE NAM...CAPE WILL STILL BE NEGLIGIBLE
OVR THE PLAINS...EXCEPT FOR SOME POCKETS OVR THE ERN MTS AND
ADJACENT PLAINS. THE GFS BRINGS SLIGHTLY HYR DEWPTS AND CAPE OF
500-1000 J/KG OVR THE PLAINS IN THE AFTERNOON. WITH THE FAIRLY
DYNAMIC NATURE OF THE SYSTEM OUT WEST...AND ANTICIPATED LEE
TROFFING...HAVE TENDED TOWARD THE WETTER GFS AND RAISED POPS A BIT
OVR THE PLAINS IN THE AFTERNOON. WILL ALSO SEE WIDESPREAD CONVECTION
OVR THE CENTRAL AND WRN RANGES AND SAN LUIS VALLEY...SOME OF WHICH MIGHT
BE ON THE STRONG SIDE. SVR POTENTIAL OVR THE PLAINS WILL DEPEND ON
EXTENT OF MOISTURE...AND WILL HAVE TO BE MONITORED OVR THE NEXT DAY
OR SO.

BY TUE...THE TROUGH HAS LARGELY PASSED AND MODEL SOLUTIONS BEGIN TO
DIVERGE. CENTRAL AND SRN ROCKIES ARE EXPECTED TO STAY IN A TROFFY
PATTERN THAT WILL KEEP TEMPS AROUND OR POSSIBLY SLIGHTLY BELOW
CLIMATOLOGIC NORMS. ANOTHER TROUGH IS EXPECTED TO SWING THRU LATE
IN THE WEEK. HAVE GONE WITH A SMOOTHED VERSION OF HPC GUIDANCE
THAT CONCURS WITH BOTH GFS AND EC SOLUTIONS IN BRINGING A SLIGHTLY
BETTER THAN AVG CHANCE AT PRECIP TO THE PLAINS BY THE END OF THE
WEEK. ROSE

&&

.AVIATION...
ISOLATED TO SCATTERED MVFR CIGS AND VSBYS DUE TO
THUNDERSTORMS THROUGH THIS EVENING.  LOCAL IFR CONDITIONS POSSIBLE
WITH ANY STRONG OR SEVERE STORMS.  SAME THING SATURDAY AFTERNOON BUT
WITH LESS COVERAGE.  AREAS OF MVFR CIGS AND VSBYS POSSIBLE LATE
TONIGHT AND EARLY SATURDAY DUE TO STRATUS AND FOG...ESPECIALLY ON
THE PLAINS. LW

AIR TO THE REGION. HOWEVER...ISOLATED THUNDERSTORMS WILL CONTINUE...
ESPECIALLY OVER THE MOUNTAIN AREAS. THE MAIN THREAT FROM THUNDERSTORMS
DURING THIS PERIOD WILL BE LIGHTNING AND WIND GUSTS UP TO 40 MPH.
