.UPDATE...
ISSUED AT 1004 AM MDT FRI JUN 22 2012
WINDS STARTING TO PICK UP ACROSS THE CWA THIS MORNING WITH
HUMIDITIES ACROSS THE AREA IN THE MID-TEENS TO SINGLE DIGITS. RED
FLAG WARNING LOOKS GOOD ATTM SO NO CHANGES TO CURRENT HIGHLIGHTS.
ANOTHER HOT...DRY DAY IN STORE AND CONTINUING THROUGH THE WEEKEND.
&&
.SHORT TERM...(TODAY THROUGH SUNDAY NIGHT)
ISSUED AT 353 AM MDT FRI JUN 22 2012
VERY DRY AND HOT WEST TO SOUTHWEST FLOW WILL PERSIST OVER THE
FORECAST AREA TODAY. ANY POTENTIAL CONVECTION WILL BE HOLDING OFF
FOR ANOTHER DAY WITH DRIER AIR SWEEPING BACK IN. HOT H7 TEMPS
WILL BE IN PLACE THIS AFTERNOON WITH TRIPLE DIGIT HEAT POSSIBLE
ACROSS THE DESERTS OF SOUTHEAST UTAH AND IN WEST CENTRAL
COLORADO INCLUDING THE GRAND VALLEY.
H5 ANALYSIS AT 00Z HAD THE H5 LOW CENTERED OVER CENTRAL NEW MEXICO
AND BY THIS EVENING SHOULD BE SHIFTING OVER THE SOUTHERN ROCKIES
AND INTO THE TX PANHANDLE REGION BY SATURDAY MORNING. GOES DERIVED
PRODUCTS INDICATE SUBTROPICAL MOISTURE LAYING ACROSS THE FAR
SOUTHERN PLAINS INTO CENTRAL MEXICO WHERE PWATS RUNNING ABOVE
NORMAL AND OVER 1.5 INCHES IN MOST CASES. AS THE LOW RE-POSITIONS
TO THE PLAINS ON SATURDAY IT WILL ALSO BEGIN TO AMPLIFY AND DRAW
THE SUBTROPICAL MOISTURE NORTHWARD TOWARD THE 4 CORNERS REGION BY
LATE AFTERNOON. THE RIDGE AMPLIFICATION WILL HELP KEEP
TEMPERATURES RUNNING ABOUT 10 DEGREES ABOVE NORMAL ON SATURDAY AND
USED A BLEND OF GUIDANCE. THE MOISTURE MOVING INTO THE SOUTHERN
COLORADO MOUNTAINS LOOKS TO BE NEAR OR ABOVE MOUNTAIN TOP LEVEL
WITH DRY AIR REMAINING AT THE LOW LEVELS. SO DRY THUNDERSTORM
DEVELOPMENT ALONG WITH GUSTY OUTFLOW WINDS LOOK TO BE THE MAIN
THREAT DUE TO INVERTED V PROFILES. NOT SURE IF COVERAGE WILL BE
SUFFICIENT FOR CRITICAL FIRE HIGHLIGHTS BUT WINDS AND LOW HUMIDITY
SHOULD CONTINUE TO BE A THREAT ACROSS THE CENTRAL AND NORTHERN CWA
WHERE STRONGER WINDS ON THE PERIPHERY OF THE RIDGE WILL EASILY BE
MIXED UP TO.
SATURDAY NIGHT INTO SUNDAY THE RIDGE WILL BE STRENGTHENING AND
EXPANDING WESTWARD WHICH WILL BE PUSHING THE MOISTURE PLUME ACROSS
THE REMAINDER OF THE CWA. THERE IS NO DISTINCT WAVE INDICATED IN
THE FLOW TO SUSTAIN CONVECTION AFTER SUNSET SO REDUCED POPS AFTER
MIDNIGHT BUT CAN NOT TOTALLY RULE OUT AN ISOLATED STORM THROUGH
THE EARLY MORNING HOURS. WITH THE ADDED MOISTURE THERE SHOULD BE
SLIGHTER BETTER CONVECTIVE COVERAGE OVER THE TERRAIN ON SUNDAY
WITH CLOUDS BUILDING EARLIER...TEMPERATURES MAY BE PUSHED BACK A
FEW DEGREES FROM SATURDAY. AGAIN DRY AIR REMAINS IN PLACE ACROSS
THE LOW LAYERS AND WINDS WILL BE MORE COMMON THAN MEASURABLE
RAINFALL. CRITICAL FIRE WEATHER CONDITIONS MAY REMAIN IN PLACE
MAINLY DUE TO THE DRY THUNDERSTORM THREAT.
.LONG TERM...(MONDAY THROUGH THURSDAY)
ISSUED AT 353 AM MDT FRI JUN 22 2012
HIGH PRESSURE CENTERED OVER THE CENTRAL PLAINS AND A TROUGH OF LOW
PRESSURE OFF THE CALIFORNIA COAST WILL PLACE THE FORECAST AREA
UNDER DEEP SOUTHERLY FLOW FOR A FEW DAYS AS WE START OFF THIS
EXTENDED PERIOD. MOISTURE WILL CONTINUE TO CYCLE NORTHWARD...WITH
DIURNALLY DRIVEN CONVECTION EXPECTED EACH AFTERNOON AND EVENING
THROUGH WEDNESDAY. THE LOW LEVELS WILL SHOW SOME
MOISTENING...WHICH COULD DRIVE ISOLATED WETTING RAINS INTO THE
REGION...BUT OVERALL...EXPECT QPF AMOUNTS TO REMAIN MEAGER.
THE DEEP SOUTHERLY PUSH BREAKS DOWN BY THURSDAY WITH DRIER
WESTERLY FLOW RESUMING AS A STRONG SYSTEM TRACKS EAST ACROSS
SOUTHERN CANADA. TEMPERATURES WILL BE RUNNING AT TO SLIGHTLY ABOVE
SEASONAL NORMS DUE THE MARGINAL MOISTURE AND EXPECTED CLOUD
COVER...BUT WILL BE BOUNCING BACK UP BY THE END OF THE WEEK AS WE
DRY BACK OUT.
