CURRENTLY...MCS WHICH MOVED DOWN ALONG W KS LAST NIGHT INTO THIS EARLY AM BROUGHT AN OUTFLOW BOUNDARY WHICH MADE IT TO THE MTNS. THIS BOUNDARY BROUGHT IN SOMEWHAT COOLER AIR TO THE REGION THIS AFTERNOON. FLOW OVER THE PLAINS EARLY THIS AFTERNOON WAS FROM AN EASTERLY COMPONENT...WITH DWPTS MAINLY IN THE 50S. REST OF THIS AFTERNOON...BEST INSTABILITY WILL BE IN MTNS AS (RELATIVELY) COOLER AIR HAS MAINLY AFFECTED PLAINS. ANTICIPATE SCTD SHOWERS AND STORMS MTN/HI VALLEY AREAS THROUGH THE EARLY EVENING HOURS. I AM ALSO ANTICIPATING BY LATE THIS AFTERNOON SHOWERS AND STORMS WILL FORM IN THE PIKES PEAK REGION AND WILL MOVE SOUTH WITH THE N FLOW ALOFT...BRINGING A THREAT OF SHOWERS AND STORMS TO THE COS/PUB REGION AND EVENTUALLY WET MTN AREA. FOR THIS REASON... INCREASED POPS SLIGHTLY FOR THESE AREAS THIS EVENING. AS FOR THE FAR E PLAINS THIS AFTERNOON...CHANCE OF SHOWERS MUCH LESS AND DECREASED POPS FAR E PLAINS TO ONLY 10% AS DRIER AIR MOVING INTO FAR E PLAINS AS PER WAT VAP IMGY. TONIGHT...COULD NOT FIND ANY REASON TO KEEP POPS GOING INTO THE EARLY MORNING HOURS...SO ENDED POPS AFTER MIDNIGHT ALL AREAS. FOR TOMORROW...NOT MUCH CHANGE IN TO THE PREVIOUS FCST PACKAGE EXCEPT TO TWEAK MAXES DOWN A BIT ON THE PLAINS. WITH NNE FLOW ALOFT AND NO FORCING...CHANCE OF PRECIP TOMORROW ON THE FAR E PLAINS NEAR ZERO... AS IT SHOULD BE A NICE SUNNY AND WARM DAY OVER THIS REGION. CLOSER TO THE MTNS...THERE WILL BE A SLIGHT CHANCE OF AFTERNOON AND EVENING SHOWERS...WHILE IN THE MTNS SCTD SHOWERS WILL PREVAIL BY EARLY AFTERNOON. /HODANISH .LONG TERM DISCUSSION (MONDAY NIGHT THRU SUNDAY) ...MAIN CONCERNS TEMPS AND POPS ESPECIALLY WED-FRI...

DIFFERENCES EXIST BETWEEN THE ETA VS AVN...WITH ETA FURTHER NORTH WITH RETROGRADING UPPER TROF THROUGH 84 HRS. AVN IS ALSO STRONGER AND SLOWER WITH WEST COAST TROF AS WELL. AVN EVENTUALLY TAKES THE FORMER FEATURE ACROSS NM THURS NIGHT. LATEST RUNS ARE STRONGER WITH THIS FEATURE THAN PREVIOUS RUNS...WHICH LEADS TO SOME UNCERTAINTIES. HOWEVER...OTHER LONG RANGE MODELS AGREE WITH THE OVERALL PATTERN. THUS HAVE COOLED OFF TEMP GRIDS JUST A BIT OUT EAST...BUT NOT AS MUCH AS GUIDANCE. HAVE MAINTAINED THE BROAD BRUSH 20 POPS AS WELL.
