AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PUEBLO CO
249 PM MDT FRI JUL 31 2009

.SHORT TERM...
(TONIGHT AND SATURDAY)

A SHRTWV TROF IS MOVING ACRS THE STATE...WHICH WL CONTINUE AIDING IN
THE DEVELOPMENT OF STORMS THROUGH THE EVENING.  AS OF 1 PM DEW
POINTS WERE STILL NR 60 OVR THE FAR SE PLAINS...WITH AROUND 50 ALONG
MUCH OF THE I-25 CORRIDOR.  THE NAM FORECAST HAS THEM DRYING OUT A
LITTLE MORE THIS AFTERNOON...WHILE THE RUC KEEPS THE DEW POINTS UP.
CURRENT ANALYSIS SHOWS 2000-2500 J/KG OF CAPE OVR THE FAR SE
PLAINS...WHICH STILL SEEMS TO BE THE MOST FAVORABLE AREA FOR SEVERE
STORM DEVELOPMENT LATER THIS AFTERNOON AND THIS EVENING.  LIMITING
FACTOR IS SHEAR VALUES OF ABOUT 25 KTS.  THUNDERSTORM ACTIVITY WL
THEN DECREASE THIS EVENING FROM WEST TO EAST AS THE SHRTWV MOVES
E...WITH SOME STORMS LIKELY LINGERING OVR THE FAR EASTERN AREAS INTO
LATE NIGHT. LATE TONIGHT THE NAM SHOWS SOME HIGH RH VALUES OVR
PORTIONS OF THE SE PLAINS IN THE WAKE OF THE PASSING TROF/FRONT. WITH
THE NORTHERLY SFC WINDS...THE BEST CHANCES FOR LOW CLOUDS WL LIKELY
BE OVR THE PALMER DVD AND ALONG THE RATON RIDGE.  THE UPR RIDGE
REBOUNDS A LITTLE OVR THE AREA ON SAT AND IT LOOKS A BIT DRIER. ALSO
WITH THE LACK OF AN UPR DISTURBANCE THUNDERSTORM CHANCES WL BE LOWER
ON SAT.  WL PROBABLY STILL SEE SOME SHOWERS/STORMS DEVELOP...MAINLY
OVR AND NR THE MTS. TEMPS WL STILL BE BELOW NORMAL.

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

SATURDAY NIGHT...STILL IN CYCLONIC FLOW PATTERN ALOFT AND WITH
LIMITED MOISTURE HAVE KEPT ISOLATED POPS MAINLY OVER THE MOUNTAINS
AND HIGH VALLEYS.  ANY ISOLATED MEASURABLE RAIN SHOULD END BEFORE MIDNIGHT.

SUNDAY...RIDGE CONTINUES TO BUILD OVER THE AREA...AND MID LEVEL
TEMPERATURES ELEVATE INTO THE MID TEENS OVER THE EAST AND UPPER
TEENS WEST...WHICH TRANSLATES INTO MAINLY 90S PLAINS...80S HIGH
VALLEYS AND 50S TO 70S MOUNTAINS. NAM12 SHOWS A LITTLE RIBBON OF
DEEPER MOISTURE IN EXTREME SOUTHEAST COLORADO...SO PUT ISOLATED
THUNDERSTORMS THERE IN THE LATE AFTERNOON AND EVENING.

MONDAY...RIDGE BUILDS IN EARNEST...WITH MID LEVEL TEMPERATURES
GOING UP ANOTHER FEW DEGREES AND AIR MASS DRYING OUT.
POSSIBILITY...AS HINTED AT IN NAM12...FOR ISOLATED THUNDERSTORMS
IN THE FAR SOUTHEAST AGAIN. WOULD GO 100 OR HIGHER IN THE
PLAINS...BUT WITH RECENT RAINS...HIGH TEMPERATURES WOULD BE HELD
BACK A FEW DEGREES.

TUESDAY AND WEDNESDAY...UPPER RIDGE CONTROLS WEATHER WITH HIGHS
90S TO AROUND 100 PLAINS...AND 80S HIGH VALLEYS. MOUNTAIN
TEMPERATURES IN THE 50S TO 70S...WITH ONLY ISOLATED THUNDERSTORMS
POSSIBLE. WHILE WIND SHOULD NOT BE AN ISSUE...DRY LIGHTNING
STRIKES WILL BE...SO DRIER AREAS COULD EXPERIENCE FIRE STARTS.

THURSDAY AND FRIDAY...AS RIDGE GETS PUSHED TO THE EAST...AND SOUTH
A BIT...MONSOON MOISTURE RETURNS...AND A LITTLE BETTER CHANCE FOR
EXPANSION OF POPS INTO THE PLAINS. ALONG WITH MORE CLOUDS A
SLIGHTLY LOWER MID LEVEL TEMPERATURES...HIGHS SHOULD COME DOWN A
CATEGORY OR SO...AS WELL. -TLM-

&&

.AVIATION...IN GENERAL...VFR CONDITIONS ARE EXPECTED AT THE 3 TAF
SITES TONIGHT AND SATURDAY.  THERE IS A SMALL CHANCE THAT STORMS OVR
OR IN THE VCNTY OF THE 3 TAF SITES COULD BRIEFLY CAUSE MVFR CIGS
AND/OR VSBYS IN HEAVY RAIN DURING THE EVENING HOURS.  LATE TONIGHT
SOME LOW CLOUDS WL BE POSSIBLE IN EL PASO COUNTY POSSIBLY NR
KCOS...HOWEVER AT THIS TIME I THINK THE NORTHERLY SFC WINDS COULD
KEEP THE LOW CLOUDS FROM AFFECTING THE AIRPORT...SO WL NOT MENTION
LOW CLOUDS IN THE TAF.

.PUB WATCHES/WARNINGS/ADVISORIES...
