ISOLATED TSRA WILL BE POSSIBLE MAINLY THIS AFTERNOON AND EARLY EVENING. BRIEF MVFR CONDITIONS COULD OCCUR AT EACH SITE AS ANY TSRA MOVE OVER.

VFR CONDITIONS ARE EXPECTED AT THE TAF SITES OVERNIGHT. PREV DISCUSSION... /ISSUED 318 AM MDT TUE SEP 25 2012/ SHORT TERM... (TODAY AND TONIGHT) WV IMAGES THIS MORNING SHOWING THE UPR LOW CIRCULATION OVR WRN UT. RADAR SHOWING SOME ECHOES OVR PORTIONS OF THE CONTDVD AND SRN SANGRES...WITH KCPW REPORTING SOME SNOW. THE UPR LOW CENTER IS FORECAST TO MOVE TO AROUND THE WRN CO BORDER BY THIS EVENING...AND THEN SHOWING LITTLE MOVEMENT OVERNIGHT. THROUGH THE MORNING HOURS...PCPN IS EXPECTED TO INCREASE OVR THE MTNS AND HIGH VALLEYS...AND THEN SPREAD OVR THE SOUTHEAST PLAINS IN THE AFTERNOON. THE MTNS WL SEE THE HIGHEST PCPN CHANCES TODAY. STILL EXPECTING TO SEE SNOW OVR THE HIGHEST PEAKS TODAY...WITH GENERALLY LIGHT ACCUMULATIONS. HIGH TEMPS TODAY WL BE A BIT COOLER...WITH GENERALLY AROUND AVERAGE READINGS OVR THE SERN PLAINS...AND SLIGHTLY BELOW AVERAGE IN THE SAN LUIS VALLEY. MSTR OVR THE FORECAST AREA OVERNIGHT IS NOT THAT IMPRESSIVE IN THE NAM...WITH THE BETTER MSTR EXPECTED TO BE TO OUR NORTH AND WEST. PCPN CHANCES ARE EXPECTED TO DECREASE...WITH THE NAM AND WRF SHOWING LITTLE CHANCE FOR PCPN ACRS THE FORECAST AREA BY LATE NIGHT. THE GFS KEEPS SOME PCPN GOING THRU THE NIGHT OVR PORTIONS OF THE SERN PLAINS. WL GO WITH JUST ISOLD POPS ACRS THE FORECAST AREA FOR THE LATE NIGHT HOURS. /28 LONG TERM... (WEDNESDAY THROUGH NEXT TUESDAY) .SHOWERS CONTINUE THROUGH THURSDAY... A MOIST AND UNSETTLED PATTERN SHOULD PERSIST THROUGH MOST OF THIS WEEK. THE UPPER LEVEL LOW THAT IS CURRENTLY MOVING INTO UT WILL ESSENTIALLY STALL OUT OVER WRN CO ON WED...AS THE SRN JET STREAM REMAINS WEAK AND A REINFORCING SHORTWAVE MOVES THROUGH MT DURING THE DAY. STILL A BIT UNCLEAR HOW MUCH PRECIP TO EXPECT...WITH POOR RUN TO RUN CONSISTENCY IN MODEL QPF. BUT WIDESPREAD SHOWERS SEEM LIKELY...ESPECIALLY FOR THE MT AREAS ON WED. WET BULB ZERO WILL DRIVE SNOW LEVELS DOWN TO ABOUT 11000 FEET THROUGH THE END OF THE WEEK...AND WITH PERSISTENT SHOWERS COULD SEE SOME LOCAL ACCUMULATIONS OF 2-6 INCHES FOR THE HIGHEST ELEVATIONS. PIKES PEAK AND INDEPENDENCE PASS COULD SEE SNOWFALL IN THAT RANGE. WITH ABUNDANT CLOUDS AND SHOWERS...HIGH TEMPS WILL BE HELD IN THE 60S TO LOWER 70S WED-THU OVER THE PLAINS...EXCEPT FOR THE FAR ERN ZONES WHICH SHOULD STAY A BIT WARMER. SHOWERS SHOULD SHIFT TO THE ERN PLAINS ON THU AS THE UPPER LOW SLOWLY LIFTS OFF TO THE NE. UNCERTAINTY GROWS TOWARD THE END OF THE WEEK... AS THE GFS KEEPS UPSLOPE FLOW OVER ERN CO...AND DRAGS ANOTHER FRONT ACROSS THE AREA LATE SAT INTO SUN. THIS SAME FEATURE IS EVIDENT IN THE ECMWF SOLUTION...THOUGH NOT QUITE AS STRONG. ENSEMBLES SHOW DECREASING POPS THROUGH THE WEEKEND...AND WILL STICK WITH THAT SCENARIO FOR NOW...BUT POPS MAY HAVE TO BE RAISED IF LATER RUNS CONTINUE TO INDICATE THIS SECONDARY FRONTAL SYSTEM. THE GFS SOLUTION ESSENTIALLY PRECLUDES ANY SUBTROPICAL MOISTURE FROM REACHING SRN CO EARLY NEXT WEEK...AND WOULD LEAD TO DRY AND WARMING CONDITIONS MON-TUE. THE LATEST EC HAS ALSO BACKED OFF ON THE SUBTROPICAL TAP. GIVEN THE DIFFICULTY MODELING THE TROPICAL IMPACT AND THE INCONSISTENT MODEL RUNS...AM NOT YET READY TO WRITE OFF THE POTENTIAL IMPACT FROM THE REMNANTS OF MIRIAM. HOWEVER...WILL STICK WITH THE ENSEMBLE CONSENSUS FOR NOW WHICH SUGGESTS THE DRYING TREND INTO EARLY NEXT WEEK. 44 AVIATION... SHOULD BE A LOT OF CLOUD COVER TODAY...BUT STILL EXPECTING VFR CONDITIONS AT THE TAF SITES. COULD SEE SOME SHOWERS IN THE VCNTY OF KALS THIS MORNING. THIS AFTERNOON KCOS...KPUB AND KALS COULD SEE SHOWERS OR TSTMS IN THE VCNTY. PCPN AND CLOUDS WL OBSCURE THE MTN TOPS AT TIMES TODAY. CHANCES FOR PCPN ARE EXPECTED TO DECREASE AFTER THE EVENING HOURS.
