AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GOODLAND KS 538 PM MDT FRI JUN 12 2009 .DISCUSSION... 208 PM MDT FRI JUN 12 2009 17Z WATER VAPOR IMAGERY INDICATED FAIRLY ZONAL FLOW ACROSS THE CWA WITH TROUGH OFF OF THE EAST COAST AND RIDGE AXIS ACROSS CENTRAL COLORADO. AT THE SFC...HIGH PRESSURE SETTLED ACROSS THE AREA IN THE WAKE OF LAST NIGHTS MCS WITH OUTFLOW BOUNDARY TO THE SOUTH OF THE AREA. 12Z RAOBS INDICATE ONLY SMALL CHANGES IN AIRMASS AT DDC AND LBF FROM 24 HOURS AGO...WITH BOTH SOUNDINGS INDICATE FAIRLY DEEP MOISTURE PROFILES REMAINING IN PLACE. MAIN FORECAST CONCERNS CONTINUE TO BE THUNDERSTORM CHANCES AND PRECIP AMOUNTS THROUGH THE PERIOD. TONIGHT...ANOTHER ROUND OF THUNDERSTORMS IS EXPECTED TO DEVELOP ACROSS EASTERN COLORADO AND DRIFT EASTWARD ACROSS A PORTION OF THE CWA OVERNIGHT. WAA DOES NOT APPEAR TO BE AS STRONG AS LAST NIGHT...AND INSTABILITY AXIS GENERALLY CONFINED TO WESTERN AND SOUTHERN CWA. 17Z VIS SATELLITE SHOWING AN AREA OF ENHANCED CU BETWEEN KCOS AND KAPA WITH SOMEWHAT DRIER AIR TO THE NORTH OF THIS AREA. INITIAL THOUGHTS ARE THAT THIS IS THE MOST LIKELY AREA FOR CONVECTION TO INITIATE...WHICH FURTHER REINFORCES THOUGHT THAT SOUTHWEST MAY BE MOST LIKELY AREA FOR PRECIPITATION TONIGHT. AS WAS THE CASE LAST NIGHT...LARGER SCALE FORCING INCREASES OVERNIGHT WHICH WILL AID IN THUNDERSTORM DEVELOPMENT OVERNIGHT. A FEW LOCATIONS PICKED UP ANOTHER INCH OF RAIN LAST NIGHT AND 3 HR FFG HAS FALLEN TO AN INCH ACROSS YUMA COUNTY. AIRMASS REMAINS FAIRLY MOIST SO SOME DECENT RAINFALL POSSIBLE TONIGHT...BUT CONFIDENCE IN PLACEMENT AND INTENSITY TO LOW FOR ANY KIND OF FLOOD WATCH ATTM. SATURDAY-SATURDAY NIGHT... H5 RIDGE AXIS WILL SHIFT EAST OVER THE AREA DURING THE MORNING WITH SUBSIDENCE ENDING ANY LINGERING MORNING SHOWERS EARLY. DRYLINE WILL DEVELOP DURING THE AFTERNOON ACROSS WESTERN CWA AND MAY PROVIDE FOCUS FOR A FEW AFTERNOON STORMS. LOTS OF SHEAR PRESENT NEAR DRYLINE...WITH VERY CURVED HODOGRAPHS IN THE EARLY EVENING. CAP MAY BE A BIT STRONG...BUT WEAKENS TO LESS THAN 25J/KG AROUND 00Z. WHILE A FEW SEVERE STORMS POSSIBLE IN THE AFTERNOON/EVENING...THINK BEST POTENTIAL WILL ONCE AGAIN BE OVERNIGHT AS STRONG WAA/305K PRESSURE ADVECTION DEVELOPS ACROSS MUCH OF EASTERN CWA OVERNIGHT. MODELS STILL SUGGESTING AIRMASS BEING ADVECTED INTO THE AREA WILL HAVE VERY HIGH MIXING RATIOS IN EXCESS OF 12 G/KG. WITH SUCH STRONG MOISTURE ADVECTION AND ELEVATED INSTABILITY IN EXCESS OF 1000 J/KG THINK SEVERE THREAT AND HEAVY RAIN THREAT MAY CONTINUE THROUGH THE NIGHT. STILL A LARGE SPREAD BETWEEN MODELS WITH WHERE MCS DEVELOPS...BUT THINK CONFIDENCE HIGH ENOUGH TO UP POPS TO THE 50-60 RANGE. SUNDAY-MONDAY...SIMILAR SET UP TO THE PAST FEW DAYS IS EXPECTED ACROSS THE AREA THROUGH THE PERIOD WITH THUNDERSTORMS DEVELOPING ALONG DRY LINE/FRONTAL ZONE WITH COVERAGE INCREASING AND SPREADING OVER THE AREA OVERNIGHT. CURRENT FORECAST LOOKS ON TRACK AND MADE ONLY A FEW MINOR CHANGES TO THE PERIOD. IN THE EXTENDED...MEDIUM RANGE MODELS STARTING TO COME INTO BETTER AGREEMENT ABOUT MORE AMPLIFIED FLOW DEVELOPING NEXT WEEK WITH STRONG RIDGE DEVELOPING ACROSS PORTION OF THE PLAINS...WITH CUT OFF LOW DEVELOPING SOMEWHERE NEAR BAJA CALIFORNIA. SOME LARGE SPREAD IN AVAILABLE ENSEMBLE DATA WITH LOCATION OF LOW AND AMPLITUDE OF RIDGE AXIS. 00Z ECMWF APPEARS THE MOST AMPLIFIED OF OPERATIONAL AND AVAILABLE ENSEMBLE DATA...BUT OVERALL DIFFERENCES ACROSS THE CWA APPEAR MINOR. WITH RIDGE BUILDING OVER THE AREA PRECIPITATION CHANCES SHOULD WIND DOWN THROUGH THE PERIOD AND CWA SHOULD GET A BRIEF BREAK FROM THE RECENT WET PATTERN. 12Z GFS MODEL HAS THROWN A WRENCH IN THE MODEL CONSISTENCY SHIFTING THE RIDGE AXIS SEVERAL HUNDRED MILES AND PUTTING CWA ON THE EAST INSTEAD OF WEST SIDE OF THE RIDGE. WITH PREVIOUS OPERATIONAL AND ENSEMBLE DATA A STRONG WARM UP LOOKED LIKELY FOR A FEW AREAS AND WHILE THIS SOLUTION IS AN OUTLIER FROM THE PREVIOUS ENSEMBLE DATA...IT DOES LOWER CONFIDENCE IN NEXT WEEK TEMPERATURE FORECAST. JRM && .AVIATION... 537 PM MDT FRI JUN 12 2009 FOR THE 00Z TAFS... VFR WILL CONTINUE WITH AN INCREASED CHANCE FOR THUNDERSTORMS THIS EVENING & INTO THE NIGHT...MAINLY AT KGLD. AFTER THE STORMS CLEAR THE BOUNDARY LEVEL MOISTURE WILL INCREASE ALONG WITH LIGHT WINDS...SO HAVE INTRODUCED SOME LOWER CEILINGS AS WE MAY DIP INTO MVFR IN THE EARLY MORNING HOURS. SATURDAY WILL BRING ANOTHER CHANCE FOR THUNDERSTORMS IN THE AFTERNOON. KJ && .GLD WATCHES/WARNINGS/ADVISORIES... KS...NONE. NE...NONE. CO...NONE. &&
