AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GOODLAND KS 230 PM MDT MON SEP 7 2009 .DISCUSSION... 226 PM MDT MON SEP 7 2009 1630Z WATER VAPOR IMAGERY INDICATED H5 RIDGE AXIS THAT HAD BEEN OVER THE AREA FOR THE PAST SEVERAL DAYS HAS SHIFTED TO THE EAST WITH LARGE TROUGH...WITH A FEW EMBEDDED SHORT WAVE TROUGHS...WAS CENTERED ACROSS THE NORTHWESTERN UNITED STATES. AT THE SFC...TROUGH AXIS REMAINED DRAPED ACROSS EASTERN COLORADO...WITH AREA OF WEAK CONVECTION/SPRINKLES ACROSS EASTERN CWA. PRECIP CHANCES AND TEMPERATURES WILL BE PRIMARY CONCERN FOR THE PERIOD. TONIGHT...ANOTHER WEAK INSTABILITY AXIS DEVELOPS ACROSS THE CWA LATE THIS AFTERNOON MAINLY ACROSS THE EASTERN CWA. AS WAS THE CASE YESTERDAY...THERE DOES NOT APPEAR TO BE ANY STRONG SFC CONVERGENCE TO HELP INITIATE CONVECTION...AND WITH SHORT WAVE TROUGH RESPONSIBLE FOR TODAYS SPRINKLES EXPECTED TO BE TO THE EAST OF THE AREA...SUBSIDENCE MAY FURTHER INHIBIT DEVELOPMENT. CURRENT TRENDS INDICATING STORMS DEVELOPING BEHIND THIS INTIAL SHORT WAVE TROUGH SO IT APPEARS HEATING ENOUGH TO OVERCOME ANY CAPPING INDUCED BY SUBSIDENCE SO WILL CARRY LOW POPS ACROSS ENTIRE AREA TONIGHT. OTHERWISE LLJ DOES NOT LOOK AS STRONG AND FORCING FAIRLY WEAK SO DO NOT PLAN ON CARRYING THUNDERSTORM CHANCES OVERNIGHT. TUESDAY-TUESDAY NIGHT...H5 TROUGH WILL MOVE ACROSS THE DAKOTAS DURING THE DAY...FORCING A COLD FRONT ACROSS THE AREA. TIMING OF THE FRONT REMAINS UP IN THE AIR...AND MOST LIKELY TIMING OF FROPA WILL BE OVERNIGHT TUESDAY. FRONTAL SCALE FORCING...ALONG WITH H5-H3 DIV Q FIELDS INDICATE FORCING FOR ASCENT ALSO MAXIMIZED DURING THIS PERIOD. WITH LATER FRONTAL TIMING...A LITTLE CONCERNED THAT BOUNDARY LAYER MAY STABILIZE BEFORE FRONT REACHES THE AREA. SREF POPS REMAIN VERY HIGH...AND CURRENT MID RANGE POPS APPEAR REASONABLE FOR THE PERIOD. WEDNESDAY-THURSDAY...FRONT WILL SETTLE ACROSS THE AREA DURING THE DAY AND WITH AFOREMENTIONED QUESTIONS IN TIMING AND GENERAL SLOWER TREND IN THE MODELS...THINK HOLDING ONTO THUNDER CHANCES REASONABLE FOR THE DAYTIME PERIOD. WEAK UPSLOPE FLOW WILL DEVELOP BEHIND THE FRONT AND WITH NO REAL DRY AIR ADVECTION TO SPEAK OF...THERE WILL BE AT LEAST A SMALL THREAT OF DIURNALLY DRIVEN STORMS THROUGH THE EVENING HOURS ON WEDNESDAY. OTHERWISE WITH SFC HIGH IN PLACE ACROSS THE AREA AND HUMID AIRMASS IN PLACE...THINK ANOTHER ROUND OF FOG OR STRATUS A REAL POSSIBILITY ACROSS PRETTY MUCH THE WHOLE AREA. FOR THURSDAY...SFC FIELDS LOOK SIMILAR TO THE PAST FEW DAYS WITH SFC TROUGH DEVELOPING ACROSS EASTERN CWA AND MOIST AIRMASS IN PLACE ACROSS MUCH OF THE AREA. IF FOG DEVELOPS IN THE MORNING THERE IS SOME CONCERN THAT WIDESPREAD STRATUS IN THE MORNING WOULD LIMIT HEATING/DESTABILIZATION ACROSS MUCH OF THE AREA. WITH MINIMAL AFTERNOON CONVECTION THE PAST FEW DAYS...THINK A DRY FORECAST IS IN ORDER UNTIL PRE FRONTAL TROUGH NEARS THE AREA THURSDAY NIGHT. HIGH TEMPERATURES...ESPECIALLY ON WEDNESDAY AS POTENTIAL EXISTS FOR POST FRONTAL STRATUS WHICH COULD REALLY INHIBIT WARMING THROUGH MUCH OF THE DAY. NAM VERY AGGRESSIVE WITH STRATUS DECK...WHILE GFS ONLY HINTS AT A BRIEF WINDOW OF LOW CLOUD POSSIBLE. STRATUS HAS FORMED FAIRLY EASILY THE PAST FEW DAYS AND WITH A SIMILAR AIRMASS MOVING BACK TO THE AREA...AM GOING TO TREND TO THE COOLER SIDE OF THINGS. IN THE EXTENDED...MAIN CONCERN FOR THE PERIOD CENTERS AROUND CLOSED H5 TROUGH EXPECTED TO DEVELOP OVER THE PLAINS. LOOKS LIKE MODELS HAVE BEEN BOUNCING AROUND WITH THE POSITION OF THE LOW...WITH A SOMEWHAT WESTWARD DRIFT APPARENT IN THE DIFFERENT RUNS. GFS 00Z ENSEMBLE MEAN AS WELL AS CLUSTERING OF ENS MEMBERS WOULD TEND TO SUPPORT A MORE EASTERLY POSITION OF THE TROUGH...BUT REGARDLESS OF EXACT POSITION SEEMS TO BE GOOD AGREEMENT THAT A LARGE TROUGH WILL IMPACT THE AREA. WITH A LARGE AMOUNT OF UNCERTAINTY IN EVOLUTION OF THE SYSTEM PLAN ON KEEPING DETAILS FAIRLY GENERALLY NOW. BOTH MAX AND MIN TEMPS WILL REMAIN BELOW NORMAL AFTER STRONG COLD FRONT SWEEPS ACROSS THE AREA ON FRIDAY. BEST PRECIPITATION CHANCES WILL BE WITH FROPA ON FRIDAY...BUT WITH POTENTIAL FOR CLOSED LOW NEAR THE AREA PLAN ON KEEPING SMALL DIURNAL CHANCES THROUGH THE PERIOD. JRM && .AVIATION... 1150 AM MDT MON SEP 7 2009 18Z TAFS...VFR IS ANTICIPATED THROUGH THE 24 HOUR TAF PERIOD. AN ISOLATED SHOWER/THUNDERSTORM MAY IMPACT THE KMCK AREA BETWEEN 23Z-04Z, HOWEVER PROBABILITIES REMAIN LOW WITH NO MENTION ANTICIPATED AT THIS TIME. && .GLD WATCHES/WARNINGS/ADVISORIES... KS...NONE.
