AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PUEBLO CO 331 PM MDT WED AUG 4 2010 .SHORT TERM... (TONIGHT AND THURSDAY) ...MORE OF THE SAME FOR THURSDAY... CURRENTLY...WARM AND MOIST REGIME CONTINUES ACROSS THE FORECAST AREA...WITH TEMPS CLIMBING INTO THE MID 70S TO LOWER 80S IN MOST LOCATIONS AND DEWPOINTS RIGHT AROUND 60 F. CONVECTIVE ACTIVITY STARTED EARLIER TODAY AT 11 AM...BUT SO FAR THE WIDESPREAD STORM ACTIVITY HAS BEEN TIED TO THE HIGHER TERRAIN. TONIGHT AND TOMORROW...HARD TO SAY ANYTHING NEW THAT HAS NOT BEEN SAID ALREADY THE PAST 4 OR 5 DAYS. THE FLASH FLOOD POTENTIAL CONTINUES UNTIL MIDNIGHT TONIGHT...THEN PICKS UP ONCE AGAIN TOMORROW AFTERNOON AND EVENING. THIS IS DUE TO A FEW FACTORS THAT HAVE NOT CHANGED AT ALL...THAT IS...THE MONSOON PLUME OVER THE 4 CORNERS CONTINUES TO LAY ACROSS COLORADO...LLVL MOISTURE OVER THE E PLAINS REMAINS IN PLACE AS EVIDENT BY DEWPOINTS RIGHT AROUND 60 F FOR THE PLAINS AND AROUND 50F FOR THE HIGH VALLEYS...AND LIGHT STEERING FLOW. THEREFORE...SOLAR INSOLATION HAS BEEN KICKING OFF SLOW MOVING STORMS OVER THE HIGHER TERRAIN THAT TAP INTO THE MOISTURE FEED...THEN INTERSECTING OUTFLOW BOUNDARIES CONTINUE THE ACTIVITY FOR THE ADJACENT PLAINS INTO THE EVENING. BOTH NAM AND GFS MODELS INDICATE A H5 VORT MAX ROLLING ACROSS THE CWA THIS EVENING THAT SHOULD HELP KEEP CONVECTION PERCULATING WELL INTO THE LATE NIGHT. RAINFALL RATES OF ANYWHERE FROM .5" TO 2" PER HOUR ARE POSSIBLE AS THE STORMS FEED OFF THE ABUNDANT MOISTURE...AND SINCE THE GROUND IS ALREADY SOMEWHAT SATURATED FROM RECENT RAINFALL...FLASH FLOODING IS DEFINITELY A POSSIBILITY. SO...LOOK FOR PERIODS OF HEAVY RAINFALL THIS EVENING MAINLY OVER THE HIGHER TERRAIN AND ALONG AND NORTH OF HIGHWAY 50 FOR THE E PLAINS. A MILD NIGHT IS FORECAST UNDER MOSTLY CLOUDY SKIES...THEN TEMPS WARM BACK UP INTO THE 80S TOMORROW FOR ANOTHER ROUND. MOORE .LONG TERM... (THURSDAY NIGHT THROUGH WEDNESDAY) ...FLASH FLOOD THREAT CONTINUES THURSDAY EVENING... MONSOON PLUME REMAINS TRAPPED WITHIN UPPER RIDGE ACROSS THE REGION KEEPING PRECIP WATERS ON THE HIGH SIDE (150%+ OF NORMAL). STILL LOOKING AT SHORTWAVE ENERGY MOVING UP FROM THE SOUTHWEST TO TRIGGER FAIRLY WIDESPREAD SHOWERS AND THUNDERSTORMS ACROSS THE REGION THROUGH FRIDAY. MODELS DIFFER ON LOCATION OF AXIS OF HEAVIER QPF...BUT SEEM TO AGREE IN LIFTING OLD FRONTAL BOUNDARY ACROSS NM/TX PANHANDLE NORTHWARD TO NEAR THE SRN CO BORDER BY THURS EVENING. GFS BREAKS OUT FAIRLY WIDESPREAD QPF ACROSS THE SOUTHEAST PLAINS THURS EVENING...NAM KEEPS FOCUS FOR HEAVIER ACROSS THE SOUTHERN SANGRES/RATON MESO REGION. GIVEN UNCERTAINTIES...WILL BROAD BRUSH SCATTERED TO LIKELY POPS ACROSS THE REGION...AND KEEP FLASH FLOOD WATCH GOING THROUGH THE EVENING HOURS. THINK HIGHEST THREAT WILL BE ACROSS THE EASTERN MTS/PLAINS. LEE TROF DEVELOPS ACROSS THE SOUTHEAST PLAINS FOR FRI AND SAT...AND DEW POINTS BEGIN TO DRY OUT ACROSS THE PLAINS...(INTO THE UPPER 40S/LOWER 50S...INSTEAD OF THE 50S AND LOWER 60S). DIFFUSE FRONTAL BOUNDARY ACROSS THE PLAINS LIFTS BACK TO THE NORTH FRI AFTN...WITH FOCUS FOR THUNDERSTORMS SHIFTING NORTHWARD ACROSS KIOWA COUNTY FRI AFTN. WILL KEEP ONLY SOME ISOLATED POPS ACROSS THE PLAINS FOR NOW...BUT FAIRLY HIGH POPS ACROSS THE MOUNTAINS AS HEATING AND RESIDUAL MOISTURE SHOULD YIELD FAIRLY GOOD COVERAGE. HARD TO PICK OUT ANY SHORTWAVES TO HELP ENHANCE CONVECTIVE COVERAGE EITHER OF THESE DAYS...SO WILL NOT HOIST ANY MORE FLASH FLOOD WATCHES FOR NOW. SUNDAY/MONDAY LOOKS WETTER IN LATEST MODEL RUNS WITH NEW SURGE OF MONSOON MOISTURE SPREADING UP FROM THE SOUTH BETWEEN WEST COAST TROF AND SRN U.S. UPPER RIDGE. FOCUS STILL LOOKS PRIMARILY OVER THE MOUNTAINS THIS DAY...WITH LEE TROF ACROSS THE PLAINS KEEPING SLIGHTLY DRIER DEW POINTS ACROSS THE REGION. LONG RANGE MODELS SUGGEST DRIER CONDITIONS FOR TUE/WED...AS SOUTHWEST FLOW ALOFT SHOVES MONSOON MOISTURE TO THE EAST AND LEE TROFING DRIES OUT THE SFC DEW POINTS INTO THE 30S AND 40S. THUS WILL PLAY A WARMING AND DRYING TREND INTO THE NEW DAY 8. -KT && .AVIATION... CONCERNS FOR THE THREE MAIN TAF SITES...KCOS...KPUB AND KALS...CONTINUE TO BE THE LIKELY PERIODS OF HEAVY RAIN PRODUCING MVFR TO IFR VISIBILITIES. THUNDERSTORM ACTIVITY TONIGHT THROUGH 03Z...AND AGAIN TOMORROW STARTING BY 17Z...WILL BRING THE THREAT OF CLOUD TO GROUND LTG AND GUSTY ERRATIC WINDS. && .PUB WATCHES/WARNINGS/ADVISORIES...
