AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PUEBLO CO 435 AM MDT SAT JUN 23 2012 .SHORT TERM... (TODAY AND TONIGHT) CRITICAL FIRE WEATHER CONDITIONS AND HIGH TEMPS ARE THE MAIN CONCERNS. AN UPR RIDGE WL BE CENTERED OVR THE TX PANHANDLE TODAY...THEN SHIFTING A BIT NORTHWARD TONIGHT. 700MB TEMPS OVR THE FORECAST AREA TODAY ARE FORECAST TO RANGE FROM 18C-22C. SHOULD SEE HIGHS OVR THE SERN PLAINS IN THE 100S AGAIN...AND GENERALLY IN THE LOWER 90S IN THE SAN LUIS VALLEY AND THE UPPER ARKANSAS RIVER VALLEY OF WESTERN FREMONT AND CHAFFEE COUNTIES. TODAYS RECORDS ARE...105 FOR PUEBLO SET IN 1954...100 FOR COLO SPGS SET IN 1954...AND 90 FOR ALS SET IN 1954. THE MODELS CONTINUE TO SHOW SOME PCPN OVR THE MTS BY MIDAFTERNOON...WITH MAYBE AN ISOLD STORM ALSO MOVING OVR THE I-25 CORRIDOR. FOR NOW WL JUST KEEP ISOLD POPS OVR THE MTS...WITH LIGHTNING AND STRONG WIND GUSTS BEING THE MAIN THREATS. RH VALUES TODAY WL BE QUITE LOW...BUT LAKE AND CHAFFEE COUNTIES ARE STILL THE AREAS WHERE THE WINDS ARE EXPECTED TO GUST HIGH ENOUGH TO WARRANT THE RED FLAG WARNING. ANY CONVECTION THAT DEVELOPS SHOULD END BY MIDEVENING. .LONG TERM... (SUNDAY THROUGH FRIDAY) ...MOSTLY HOT WITH SOME HIGH BASED STORMS... .SUNDAY...ANOTHER HOT DAY OVER THE REGION WITH UPPER LEVEL HIGH CENTERED OVER EASTERN COLORADO AND WESTERN KANSAS. MAIN CONCERN IS SOME HIGH LEVEL MOISTURE OVER WESTERN COLORADO. MODELS TEND TO BE OVERZEALOUS WITH BRINGING MID LEVEL MOISTURE NORTHWARD IN THE MONSOON PLUME. WATER VAPOR IMAGE ALONG WITH 00Z RAOB CHARTS SHOW A AREA OF MODEST MID LEVEL MOISTURE EXTENDING FROM SOUTH CENTRAL ARIZONA INTO SOUTHERN COLORADO. THIS AREA OF MOISTURE WILL SLOWLY LIFT NORTHWARD ON SUNDAY INTO NORTHWEST COLORADO. THE OTHER AREA OF UPPER LEVEL MOISTURE OVER NORTHERN MEXICO WILL GET ADVECTED TO THE NORTHWEST...THEN TO THE WEST...AND THIS MOISTURE WILL REMAIN WEST OF THE CWA. DRIER MID LEVEL AIR OVER TEXAS WILL GET ADVECTED INTO MUCH OF THE REGION ON SUNDAY. BELIEVE COVERAGE OF LIGHTNING WILL BE TOO LOW TO WARRANT A FIRE WEATHER WATCH AT THIS TIME...BUT WILL HAVE TO WATCH FOR GREATER COVERAGE OF DRY CONVECTION. TEMPERATURES WILL BE WELL ABOVE NORMAL SUNDAY AND ONLY TWEAKED CURRENT FORECAST. .MONDAY...HOT WEATHER CONTINUES OVER THE CWA...WITH THE REGION OF UPPER LEVEL MOISTURE DRIFTING FURTHER NORTH OF THE AREA. DID NOT CHANGE FORECAST MUCH...AND CONVECTION COVERAGE IS EVEN LOWER THAN SUNDAY. .TUESDAY AND WEDNESDAY...SHORTWAVE IS FORECAST TO MOVE ONSHORE OVER CALIFORNIA AND RIDE OVER THE RIDGE ON TUESDAY AND WEDNESDAY. MOST OF THE COOLER AIR ASSOCIATED WITH THIS TROUGH WILL STAY TO THE NORTH OF THE REGION. ANTICIPATE ONLY MODEST COOLING WITH THIS SYSTEM...WITH TEMPERATURES STILL ABOVE AVERAGE. MAIN CONCERN IS DRY LIGHTNING THREAT WITH THIS SYSTEM. MOST DRY LIGHTNING OUTBREAKS ARE ASSOCIATED WITH A DISTURBANCE WHICH MOSTLY PASSES TO THE NORTH OF THE REGION. TOO EARLY TO GET SPECIFIC...BUT DISTURBANCES COMING ONSHORE OVER THE NORTHERN CALIFORNIA COAST THIS TIME OF YEAR TYPICALLY DO NOT HAVE MUCH LOWER OR MID LEVEL MOISTURE. .THURSDAY AND FRIDAY...AS THE DISTURBANCE MOVES EASTWARD INTO THE NORTHERN MIDWEST...SURFACE HIGH PRESSURE WILL DEVELOP OVER THE HIGH PLAINS. FRONT MAY MOVE FAR ENOUGH SOUTH TO BRING COOLER AND MORE MOIST LOWER LEVEL AIR TO THE PLAINS...AND MAYBE THE EASTERN MOUNTAINS. CURRENT GRIDS ONLY HAVE MODEST COOLING TOWARDS THE END OF THE WEEK...WITH TEMPERATURES STILL ABOVE NORMAL TO NEAR NORMAL. AIR ALOFT OVER THE PLAINS WILL REMAIN WARM...WHICH WOULD TEND TO CAP CONVECTION. GIVEN THE PAST MODEL TRENDS...DID NOT TOUCH GRIDS MUCH WHICH LEAN TOWARDS A WARMER AND DRIER SOLUTION. MOUNTAINS AND HIGH VALLEYS WILL CONTINUE TO BE HOT AND DRY WITH ONLY HIGH BASED STORMS. --PGW-- && .AVIATION... WITH AN UPR RIDGE BEING OVR THE AREA...VFR CONDITIONS WL BE FOUND AT KCOS...KPUB AND KALS FOR THE NEXT 24 HRS. && .PUB WATCHES/WARNINGS/ADVISORIES...

RAPID RATES OF FIRE GROWTH AND SPREAD WILL BE POSSIBLE WITH ANY FIRES. ISOLATED THUNDERSTORMS WILL BE POSSIBLE OVER AND NEAR THE MOUNTAINS THIS AFTERNOON AND EVENING...WITH THE MAIN THREATS BEING LIGHTNING AND WIND GUSTS TO 40 MPH. .DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY ISOLATED TO SCATTERED THUNDERSTORMS ARE POSSIBLE MOST AFTERNOONS AND EVENINGS OVER THE MOUNTAINS AND HIGH VALLEYS. THE MAIN THREATS FROM THE STORMS WILL BE LIGHTNING AND GUSTY WINDS. SINCE THE ATMOSPHERE WILL BE RELATIVELY DRY...THE STORMS WILL NOT PRODUCE MUCH RAINFALL. WITH DRY VEGETATION OVER THE REGION...THERE ARE CONCERNS THE LIGHTNING STRIKES CAN START FIRES. THE GREATEST CHANCES FOR THE MOSTLY DRY THUNDERSTORMS WILL BE TUESDAY AND WEDNESDAY. .SPOTTER INFORMATION STATEMENT... WEATHER SPOTTERS WILL NOT BE NEEDED TODAY OR TONIGHT. 28/06
