AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PUEBLO CO 347 PM MDT WED JUL 27 2011 .SHORT TERM... (TONIGHT AND THURSDAY) CURRENTLY...THUNDERSTORMS HAVE BEEN SLOWLY INCREASING EARLY THIS AFTERNOON ALONG THE CONTINENTAL DIVIDE AND EASTERN MOUNTAINS. WHILE BASE REFLECTIVITY REMAINS SPARSE...A QUICK LOOK AT THE MOSAIC COMPOSITE IMAGERY SHOWS INCREASING CORE STRENGTH OVER THE MOUNTAINS. THUNDERSTORMS HAVE ALSO BEGUN TO PULSE ACROSS THE EASTERN PLAINS. TEMPERATURES HAVE BEEN WARM OVER THE PLAINS WITH HIGHS IN THE MID TO UPPER 90S WHILE DEW POINTS HAVE REMAINED IN THE UPPER 40S TO LOWER 50S HOWEVER WINDS HAVE REMAINED WEAK WITH LITTLE UPSLOPE FLOW. HI-RES MODELS IN AGREEMENT THIS AFTERNOON...ALBEIT A BIT FAST ON CONVECTIVE DEVELOPMENT...ON WIDESPREAD THUNDERSTORMS THIS AFTERNOON AND EVENING FOR SOUTHERN COLORADO. AN UPPER LEVEL SHORTWAVE TROUGH CURRENT OVER UTAH IS FORECAST TO BEGIN MOVING EAST INTO WESTERLY COLORADO TONIGHT. EXPECT THUNDERSTORMS TO INCREASE IN COVERAGE THIS AFTERNOON AND SPREAD EAST INTO THE PLAINS THROUGH THIS EVENING. SURFACE FLOW WILL LIKELY INCREASE AS SURFACE CYCLOGENESIS TAKES PLACE ALONG THE LEE SLOPES EFFECTIVELY ENHANCING LOW LEVEL UPSLOPE FLOW THIS EVENING. MODELS IN GOOD AGREEMENT WITH THE HIGHEST CONCENTRATION OF THUNDERSTORMS BEING OVER THE MOUNTAINS...AND NORTH OF HIGHWAY 50 AS THE WAVE OF THUNDERSTORMS EJECTS OVER THE PLAINS. PWAT VALUES ARE AROUND 1.5 INCHES WHICH SHOULD MEAN THOSE STORMS WILL BE EFFECTIVE PRECIPITATION PRODUCERS. FLOW ALOFT OUT OF THE WEST SHOULD HELP PROVIDE STEADY STORM MOVEMENTS AND LIMIT FLASH FLOOD POTENTIAL. THUNDERSTORMS ARE FORECAST TO DISSIPATE THROUGH MIDNIGHT OVER THE MOUNTAINS WITH A COUPLE OF STORMS POSSIBLE INTO TOMORROW ALONG THE CONTINENTAL DIVIDE. THUNDERSTORMS OVER THE PLAINS WILL SHIFT EAST INTO KANSAS THROUGH 09Z. THE UPPER LEVEL SHORTWAVE TROUGH IS FORECAST TO TRACK ACROSS THE ROCKIES AND EJECT INTO THE CENTRAL PLAINS BY TOMORROW AFTERNOON. MODELS IN GOOD AGREEMENT IN BREAKING OUT ANOTHER ROUND OF WIDESPREAD THUNDERSTORMS FOR MUCH OF THE REGION. THE ONLY AREA TO MISS OUT MAY BE THE CENTRAL MOUNTAINS WHERE SUBSIDENCE BEHIND THE EXITING SHORTWAVE WILL LIKELY LIMIT THUNDERSTORM COVERAGE. LOW LEVEL FLOW WILL TURN EASTERLY ACROSS THE PLAINS ENHANCING UPSLOPE FLOW BY THE AFTERNOON. EXPECT THUNDERSTORMS TO FIRE ALONG THE EASTERN MOUNTAINS AND EJECT INTO THE PLAINS THROUGH THE AFTERNOON. AT THE SURFACE A WEAK BOUNDARY WILL BE IN PLACE OVER THE PLAINS WHICH SHOULD ALSO ENHANCE THUNDERSTORM DEVELOPMENT. PWAT VALUES WILL REMAIN ELEVATED AND LOCALLY HEAVY RAINFALL IS LIKELY ACROSS THE PLAINS BY TOMORROW AFTERNOON. HIGH TEMPERATURES FOR TOMORROW WILL BE SLIGHTLY COOLER GIVEN THE INCREASED POTENTIAL FOR THUNDERSTORM DEVELOPMENT WITH HIGHS IN THE UPPER 80S TO MID 90S FOR THE PLAINS. MOZLEY .LONG TERM... (THURSDAY NIGHT THROUGH WEDNESDAY) ...MONSOON FLOW CONTINUES WITH SUBTLE FEATURES... ...THURSDAY NIGHT AND FRIDAY...SURFACE BOUNDARY SHOULD MOVE TO JUST SOUTH OF THE CWA BY FRIDAY MORNING. POSSIBLE MCS OVER WESTERN KANSAS THURSDAY NIGHT COULD ENHANCE FLOW OF LOW LEVEL MOISTURE WESTWARD. WITH DEEP MOISTURE OVER THE REGION...THERE IS THE POTENTIAL FOR STORMS OVER THE ENTIRE CWA. DECIDED NOT TO INCREASE POPS AT THIS TIME AS SUBTLE FEATURES WILL AFFECT THE LOCATION OF THE CONVECTION. NAM FAVORS PRECIPITATION NEAR THE NEW MEXICO BORDER WHILE THE GFS WANTS TO KEEP THE HIGHEST COVERAGE FURTHER SOUTH. .SATURDAY AND SUNDAY...UPPER HIGH WILL RETROGRADE OVER THE WEEKEND WITH THE CORE OF THE MONSOON PLUME MOVING INTO WESTERN COLORADO. BOTH THE NAM AND GFS TRY TO ADVECT SOME DRIER MID LEVEL AIR INTO EASTERN COLORADO FROM THE NORTH. KEPT THE HIGHEST POPS OVER THE MOUNTAINS DURING THE WEEKEND WITH ONLY ISOLATED POPS OVER THE PLAINS. 12Z GFS HAS SOME MOISTURE FROM TS DON MOVING INTO SOUTHEAST COLORADO BY SUNDAY AFTERNOON. THIS SOLUTION IS AN OUTLIER AMONG MODELS AND HURRICANE CENTER GUIDANCE KEEPS TS DON WELL TO THE SOUTH OF THE CWA. REMNANT OF UPPER LOW OVER THE WESTERN GULF OF MEXICO WILL SLOWLY MOVE TOWARDS THE NORTHWEST..AND COULD REACH THE CWA BY LATE SUNDAY. THIS FEATURE MAY HELP INCREASE POPS OVER THE WESTERN PORTION OF THE CWA SATURDAY AND SUNDAY. .MONDAY THROUGH WEDNESDAY...LONGER RANGE MODELS FLATTEN THE RIDGE WITH THE POTENTIAL FOR UPSLOPE FLOW DEVELOPING OVER THE PLAINS. THE MODELS SUGGEST PRECIPITATION CHANCE COULD INCREASE OVER THE PLAINS SOMETIME DURING THIS PERIOD. WITH THE TIMING DIFFERENCES IN THE MODELS...DID NOT CHANGE POPS MUCH DURING THIS PERIOD. --PGW-- && .AVIATION... THUNDERSTORMS HAVE BEEN SLOW TO DEVELOP THIS AFTERNOON BUT HAVE FINALLY TAKEN OFF. LATEST RADAR IMAGERY INDICATES CELLS FIRING WEST OF KCOS WHICH SHOULD MOVE NEAR/OVER THE TERMINAL 28/01Z. THESE THUNDERSTORMS WILL PRODUCE VERY HEAVY RAINFALL AS THEY PASS ALONG WITH GUSTY OUTFLOW WINDS AND IFR TO LIFR CONDITIONS. STILL THINKING KPUB WILL SEE THUNDERSTORMS LATE THIS AFTERNOON AND EVENING HOWEVER RADAR HAS BEEN SLOW TO FILL IN TO THE WEST. WILL ADJUST TAF SHORTLY TO HOLD OFF ON THUNDERSTORM IMPACTS UNTIL A BIT LATER IN THE AFTERNOON. ANY STORMS THAT MOVE OVER THE TERMINAL WILL PRODUCE LOCALLY HEAVY RAINFALL AND GUSTY OUTFLOW WINDS ALONG WITH IFR TO LIFR CONDITIONS. THUNDERSTORMS HAVE DEVELOPED OVER THE SAN JUAN RANGE AND WILL MOVE OVER THE SAN LUIS VALLEY NEAR KALS THROUGH THIS EVENING. ANY CELLS THAT MOVE OVER THE TERMINAL WILL PRODUCE MVFR TO IFR CONDITIONS THROUGH THIS EVENING. MOZLEY && .PUB WATCHES/WARNINGS/ADVISORIES... NONE. && 88/06

THIS WILL MEAN CONTINUED SCATTERED THUNDERSTORMS ACROSS THE MOUNTAINS EACH AFTERNOON AND EVENING...WITH ISOLATED TO SCATTERED THUNDERSTORMS ACROSS THE PLAINS. THE BEST CHANCE FOR RAIN ACROSS THE PLAINS WILL BE THURSDAY. THE MAIN THREAT WITH THUNDERSTORMS WILL BE LOCALLY HEAVY RAINFALL...WITH THE POTENTIAL FOR EXCESSIVE RUNOFF AND FLASH FLOODING FOR AREAS WITH POOR DRAINAGE SUCH AS THE BURN SCARS AND URBAN AREAS.
