AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PUEBLO CO 405 AM MDT SAT JUN 20 2009 .SHORT TERM... (TODAY AND TONIGHT) ...HEAVY RAIN POSSIBLE TODAY... CURRENTLY...WV IMAGERY IS SHOWING SWATH OF MID-UPPER LEVEL MOISTURE MOVING NWD THRU THE TX PANHANDLE AND ERN NM. SOME VERY HEAVY RAINFALL HAS BEEN FALLING OVER THE RATON AND SRN I-25 CORRIDOR...WITH RATES APPROACHING 1 INCH PER HR IN PLACES. THIS HEAVY CONVECTION WILL CONTINUE TO DIMINISH THIS MORNING TO THE S...AND FLOODING IS NOT EXPECTED TO BE A MAJOR CONCERN THERE. RAIN HAS BEEN SLOW TO ADVANCE TO HGHWY 50 AND NWD...WITH DOWNSLOPING OVER THE LOWER ARK VALLEY HELPING TO KEEP THINGS GENERALLY DRY AS OF 330 AM. HOWEVER...AS THE SHORTWAVE OVER SRN AZ CONTINUES TO TRACK NWD...SHOULD SEE THE PRECIP SHIELD CONTINUE TO ADVANCE AS WELL. DEWPTS ARE CURRENTLY IN THE 50S S OF HGWY 50...WITH EVEN A FEW LOWER 60S OVR THE SERN GRASSLANDS. PRECIP H2O WILL BE IN THE 200 PERCENT ABV AVG RANGE TODAY. LOOKS LIKE BEST TIMING FOR POTENTIALLY HEAVY RAINFALL WILL BE IN THE LATE MORNING TO EARLY AFTERNOON HOURS OVR THE NRN I-25 CORRIDOR. INSTABILITY WILL BE LIMITED...ESPECIALLY GIVEN LACK OF INSOLATION...BUT MUCAPES WILL BE AROUND 1000 J/KG...AND BULK SHEARS AROUND 50 KTS. SO...A FEW STORMS COULD BE ON THE STRONG SIDE ESPECIALLY NEAR THE I-25 CORRIDOR EARLY THIS AFTERNOON. MAIN THREAT WILL BE HAIL THAT COULD BE MARGINALLY SVR IN THE STRONGEST CELLS. WILL ALSO HAVE TO KEEP A CLOSE EYE ON THE SMALL STREAMS AND BASINS TODAY WITH SOME LOCAL FLOODING POSSIBLE. TEMPS WILL BE EVEN LOWER THAN YESTERDAY WITH SIGNIFICANT CLOUD COVER AND PRECIP...AND WE MAY NOT GET OUT OF THE 70S OVR THE PLAINS. WITH H6 TEMPS RUNNING AROUND 0 DEG C TODAY...COULD EVEN SEE SOME SNOWFALL AT THE SUMMIT OF PIKES PK LATER TODAY. PRECIP WILL WIND DOWN FAIRLY QUICKLY THIS EVE AS THE SHORTWAVE MOVES INTO WY AND NE BY EARLY EVE. SHOULD BE GENERALLY DRY BY LATE EVE...WITH ONLY A FEW LINGERING SHOWERS OVER THE CENTRAL MTS. WILL HAVE TO WATCH FOR THE DEVELOPMENT OF SOME PATCHY FG BY SAT MORNING FOR AREAS THAT RECEIVE SIGNIFICANT RAINFALL TODAY. ROSE .LONG TERM... (SUNDAY THROUGH FRIDAY) IT DRIES OUT AND WARMS UP FOR SUN AND MONDAY AS UPPER RIDGE OVER THE GULF COAST/SRN PLAINS BUILDS TO THE NORTHWEST. BY MON...H7 TEMPS WARM TO BETWEEN +16 TO +18C WITH GFS EVEN SHOWING SOME +19 TO +20C ACROSS THE SAN LUIS VALLEY/SE MTS/SRN I-25 CORRIDOR. THIS SHOULD RESULT IN MAX TEMPS PUSHING TO NEAR 100 ACROSS THE PLAINS WITH 70S AND 80S FOR THE MOUNTAIN VALLEYS. HAVE CONTINUED TO THE TREND OF WARMING UP MAX TEMPS. NOT MUCH MOISTURE IN THE MODELS BUT NAM DOES SHOW SOME MEAGER HIGH BASED MOISTURE BOTH DAYS TO WARRANT SOME ISOLATED POPS ACROSS THE HIGHER MOUNTAINS. BY TUESDAY...SOUTHERLY FETCH ALOFT STARTS TO ADVECT SOME MODEST MONSOON-LIKE MOISTURE NORTHWARD. SO SHOULD START TO SEE AN INCREASE IN AFTERNOON THUNDERSTORMS OVER THE MOUNTAINS ONCE AGAIN. INCREASING MID/HIGH CLOUD COVER MAY HELP TO TAKE THE EDGE OFF MAX TEMPS ACROSS THE AREA...BUT WITH H7 TEMPS STILL PUSHING +16 TO +18C...SHOULD STILL SEE MAX TEMPS CLIMB INTO THE 90S ACROSS THE PLAINS. SHORTWAVE ENERGY CUTTING ACROSS THE NRN US ROCKIES ON WEDNESDAY CUTS DOWN THE UPPER RIDGE AND ALLOWS A WEAK COLD FRONT TO DROP INTO THE SE PLAINS BY WED AFT. 00Z GFS DEVELOPS AN MCS ALONG THIS FRONT WED NIGHT SOMEWHERE ACROSS EASTERN CO/WRN KS. ECMWF KEEPS THE FRONTAL BOUNDARY FARTHER NORTH. THURS THROUGH FRI TRENDS TOWARDS COOLER AND POTENTIAL WETTER CONDITIONS WITH SOUTHWEST FLOW ALOFT CONTINUING TO ADVECT MOISTURE UP FROM OLD MEXICO AND REMNANTS OF AN OLD FRONTAL BOUNDARY WAVERS NORTH AND SOUTH THROUGH THE SOUTHEAST PLAINS. THIS FAR OUT...DETAILS ARE LIKELY TO CHANGE. ADDED SOME ISOLATED POPS FOR WED NIGHT ACROSS THE PLAINS. OTHERWISE NO CHANGES MADE TO GRIDS FOR THURS AND BEYOND. -KT && .AVIATION...MVFR CIGS AND VIS LIKELY AT TIMES TODAY FOR KCOS AND KPUB...PARTICULARLY IN THE 17-22Z TIME FRAME. HEAVY SHWRS WITH A FEW EMBEDDED TS WILL BE POSSIBLE FOR MUCH OF THE DAY. SHOULD SEE A GOOD AMT OF CLEARING IN THE 03-06Z TIME FRAME TONIGHT. SOME PATCHY FG MAY DEVELOP LATE TONIGHT OR SAT MORN IN THOSE AREAS THAT SEE RAINFALL TODAY. ROSE && .PUB WATCHES/WARNINGS/ADVISORIES... NONE. && 44/31
