AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PUEBLO CO 357 AM MDT SUN JUL 25 2010 .SHORT TERM... (TODAY AND TONIGHT) MAIN CONCERNS INCLUDE PCPN CHANCES AND THE POTENTIAL FOR HEAVY RAIN AND FLASH FLOODING. STARTING TO SEE MORE PCPN MOVE INTO THE SERN PLAINS FROM THE SOUTH THIS MORNING...AS A VORT MAX AND WEAK UPR LOW IS SLOWLY WORKING ITS WAY NORTH OVR THE SERN PLAINS. HOWEVER AN UPR RIDGE OVR WRN CO IS EXPECTED TO KEEP THIS SYSTEM FROM MAKING ITS WAY TOO FAR NORTH AND WEST AND THUS LOOKS LIKE IT WILL MAINLY AFFECT THE SERN PLAINS TODAY AND TONIGHT. WL BASE FORECAST ON 06Z NAM12 WHICH KEEPS THE BEST CHANCES FOR PCPN AND HEAVY RAIN GENERALLY SOUTH OF HWY 50...EXCEPT OVR THE FAR ERN AREAS. THUS WL REMOVE THE FLASH FLOOD WATCH FOR WRN PORTIONS OF THE CWA...AS WELL AS FOR THE NRN SANGRES...THE WET MTS...FREMONT...PUEBLO...TELLER AND EL PASO COUNTIES FOR TODAY. LEAVING THE SRN SANGRES AND SE FOOTHILLS...AND THE FAR SERN PLAINS STILL IN THE WATCH. HAVE DECIDED TO CUT BACK TSTM CHANCES TO ISOLD OVER THE SERN PLAINS AS LAPSE RATES ARE 5-6 C/KM. PRECIPITABLE WATER VALUES OVR ERN AREAS TODAY ARE FORECAST TO BE 150-180 PERCENT OF NORMAL. MID LEVEL WINDS TODAY OVR THE SERN PLAINS ARE FORECAST TO BE 15-20 KTS...SO PCPN AREAS SHOULD MOVE. BACA AND ERN LAS ANIMAS COUNTIES HAVE OVER THE LAST TWO DAYS SEEN PCPN ACCUMULATIONS OF 1-3 INCHES EACH DAY...AND THUS ANY HEAVY RAIN IN THESE AREAS COULD EASILY CAUSE FLASH FLOODING PROBLEMS. OVR WRN AREAS TODAY...SHOULD SEE THE TYPICAL DIURNAL SHOWERS AND TSTMS. TEMPS TODAY ARE CHALLENGING...WL JUST GO WITH A BLEND OF GUIDANCE NUMBERS BUT WL LEAN MORE TOWARD THE WARMER MAV IN MOST AREAS. TONIGHT SHOULD SEE PCPN START DECREASING IN THE EVENING HOURS. PCPN CHANCES HOWEVER SHOULD REMAIN QUITE HIGH OVR THE FAR SE AND SRN AREAS OF THE SE PLAINS AT LEAST FOR THE EVENING HOURS. THEN BY ABOUT MIDNIGHT SHOULD SEE MOST PCPN END...EXCEPT WL KEEP SOME LOW PCPN CHANCES GOING OVR AREAS NR THE KS BORDER. WITH THE DECREASING PCPN CHANCES THIS EVENING WL ALSO TRIM BACK THE FLASH FLOOD WATCH AREA AS THIS HAPPENS TO BETTER MATCH MY POP GRIDS. .LONG TERM... (MONDAY THROUGH SATURDAY) MONDAY AND TUESDAY...UPPER LEVEL RIDGE OF HIGH PRESSURE IS FORECAST TO BE DIRECTLY OVER THE 4 CORNERS AND COLORADO TO START THE WEEK...PRODUCING VERY WARM TEMPS AND ESSENTIALLY DRY CONDITIONS. STILL VERY HARD TO TOTALLY ELIMINATE DIURNAL MT CONVECTION...BUT DID ALTER POP GRIDS SLIGHTLY TO SHOW A LATER START AND TAPERED BACK POPS OVER THE PLAINS. H7 TEMPS OF 16-20 C FOR TUES MEANS THAT TUESDAY IS THE WARMEST DAY OF THE EXTENDED FORECAST. WEDNESDAY AND THURSDAY...UPPER RIDGE STARTS TO WEAKEN A BIT AND SLOWLY MIGRATE TO THE E-SE...ALLOWING SOME MID AND HIGH LEVEL MOISTURE TO START SNEAKING BACK UP INTO THE 4 CORNERS REGION. MAINTAINED ONGOING WIDESPREAD ISOLATED POPS...AS WELL AS MAX TEMPS BOTH DAYS ABOUT 5 DEGREES COOLER THAN TUE. FRIDAY AND SATURDAY...LONG RANGE MODELS INDICATE THAT THE UPPER HIGH PRESSURE FULLY BUILDS ACROSS TX AND OK...OPENING UP A MONSOONAL TAP FOR COLORADO. ONGOING GRIDS PAINT NEAR NORMAL TEMPS FOR THE EXTENDED...AS WELL AS A SLIGHTLY BETTER CHANCE FOR DIURNAL CONVECTION SO BROADBRUSHED ISOLATED POPS ALL AREAS. IF CURRENT SOLUTION CONTINUES...THEN THE WEEKEND WILL HAVE TO BE COOLED OFF ALONG WITH AN INCREASE IN PCPN COVERAGE. MOORE && .AVIATION... SEEING SOME LOW CLOUDS IN SOME AREAS OF THE SERN PLAINS THIS MORNING WHICH WITH THE LOW LEVEL ERLY FLOW COULD REACH KPUB RESULTING IN IFR OR MVFR CIGS. THERE WL ALSO BE SOME SHOWERS WORKING NORTHWARD OVR THE SERN PLAINS THIS MORNING. THIS AFTERNOON AND EARLY THIS EVENING WE COULD SEE SOME ISOLD SHOWERS AND TSTMS AT THE THREE TAF SITES...WITH KPUB HAVING THE BEST CHANCE. THESE SHOWERS AND STORMS COULD BRIEFLY CAUSE MVFR CONDITIONS. PCPN CHANCES SHOULD DECREASE OR END BY MID EVENING AT THE TAF SITES. && .PUB WATCHES/WARNINGS/ADVISORIES... FLASH FLOOD WATCH THROUGH THIS EVENING FOR COZ095>098. FLASH FLOOD WATCH THROUGH THIS EVENING FOR COZ094-099. FLASH FLOOD WATCH THROUGH THIS AFTERNOON FOR COZ074-075-087-088- 093. && 28/27

HEAVY RAINFALL WITH THESE SHOWERS AND STORMS WILL HAVE THE POTENTIAL TO PRODUCE FLASH FLOODING...ESPECIALLY IN BACA AND PORTIONS OF LAS ANIMAS COUNTY WHERE RAIN ACCUMULATIONS OVER THE PAST COUPLE OF DAYS...HAVE SATURATED THE SOIL. THE AREA THAT WILL HAVE THE GREATEST POTENTIAL FOR FLASH FLOODING WILL GENERALLY BE SOUTH OF A LINE FROM THE SOUTHERN SANGRE DE CRISTO MOUNTAINS TO EADS. THE REST OF THE FORECAST AREA WILL SEE ISOLATED TO SCATTERED THUNDERSTORMS MAINLY THIS AFTERNOON AND EVENING...WITH THE MAIN THREATS BEING LIGHTNING AND MAYBE SOME LOCALLY HEAVY RAINFALL. THIS EVENING THE GREATEST POTENTIAL FOR FLASH FLOODING WILL BE GENERALLY EAST OF A LINE FROM EASTERN LAS ANIMAS COUNTY TO EADS...ENDING BY MIDNIGHT. .DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY ISOLATED AFTERNOON AND EVENING THUNDERSTORMS ARE FORECAST MAINLY FOR THE HIGHER TERRAIN FOR BOTH MONDAY AND TUESDAY. THE MAIN THREATS FROM THESE STORMS WILL BE LIGHTNING AND GUSTY WINDS TO AROUND 40 MPH. SMALL HAIL AND LOCALLY HEAVY RAINFALL MAY ALSO ACCOMPANY THE STRONGEST STORMS. MONSOONAL MOISTURE WILL BE ON THE INCREASE ACROSS THE STATE BEGINNING ON WEDNESDAY. THIS WILL PROVIDE THE FUEL FOR A GREATER CHANCE AND WIDER COVERAGE OF THUNDERSTORM ACTIVITY THROUGH THE END OF THE WEEK. STORM CHANCES WILL BE GREATEST OVER THE MOUNTAINS AND HIGHER TERRAIN...BUT WILL SPREAD ACROSS THE ADJACENT PLAINS AS WELL. THE MAIN THREATS FROM THESE STORMS WILL BE LIGHTNING AND GUSTY WINDS TO AROUND 40 MPH...WITH SMALL HAIL AND LOCALLY HEAVY RAINFALL ALSO POSSIBLE. .SPOTTER INFORMATION STATEMENT... WEATHER CONDITIONS THAT MEET REPORTING CRITERIA FOR SPOTTERS WILL BE POSSIBLE TODAY AND THIS EVENING OVER PORTIONS OF THE SOUTHEAST PLAINS. 28/27
