Area forecast discussion, Jul 28, 3:38 PM CDT, 23 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WICHITA KS 338 PM CDT TUE JUL 28 2009 .DISCUSSION... TONIGHT: RAIN SHOWERS/THUNDERSTORMS WILL LIKELY PERSIST INTO THE EVENING ACROSS SOUTHERN HALF OF AREA AS FRONT MAKES SLOW PROGRESS SOUTH. INSTABILITY SUFFICIENT FOR ISOLATED SEVERE...WITH WIND THREAT ON STORM COLLAPSE AND LARGE HAIL WITH ROTATING STORMS. BASED ON OBSERVATIONS AND TRENDS...GLOBAL FORECAST SYSTEM MODEL IS WAY TOO AGRESSIVE WITH LOW LEVEL DRY AIR. SUSPECT NORTH AMERICAN MODEL IS CLOSER TO CORRECT...COULD EVEN BE LOW CLOUDS/MODEST FOG ACROSS MUCH OF THE DAY BY DAYBREAK. AS A RESULT WENT WARMER THAN GUIDANCE AND BASED MINIMUMS ON ANTICIPATED DEWPOINTS. WED: W FLOW ALOFT SHOULD INCREASE WARM AIR ADVECTION/MOISTURE ADVECTION FROM WEST TO EAST DURING THE DAY ON TUE. THIS SHOULD CAUSE PRECIPITATION TO BREAK OUT ACROSS WEST AND SPREAD EAST DURING THE DAY WITH BEST CHANCES TOMORROW NIGHT. TEMPERATURES WILL LIKELY BE WELL BELOW NORMAL GIVEN EXTENSIVE CLOUD COVER. THU-FRI: KEPT LOW PROBABILITY OF PRECIPITATION GOING MAINLY FOR CONSENSUS...BUT SUSPECT PRECIPITATION WILL BE LIMITED TO SOUTHEAST HALF OF THE FORECAST AREA AT BEST. TEMPERATURES VERY TRICKY AND DEPENDENT ON AMOUNT OF RAIN TONIGHT/WED AND SPEED OF CLEARING. TEMPERATURES SHOULD REBOUND WITH MORE SUNSHINE ON FRI. TEMPERATURES TRICKIEST IN SOUTHEAST KS WHERE SOME CLOUDS MIGHT LINGER ON FRI. SAT-TUE: CONFIDENCE HAS LOWERED FROM YESTERDAY. WHILE 0000 UTC EUROPEAN CENTRE FOR MEDIUM RANGE WEATHER FORECASTS MODEL ENSEMBLE DATA WAS NOT AVAILABLE TO PERUSE...COMPARISION OF 0000 UTC RUN WITH PREVIOUS 3 RUNS SHOWS CONSIDERABLE CHANGE WITH STRENGTH/LOCATION OF UPPER WAVE AND RESULTANT SURFACE FRONT ON SAT. GLOBAL FORECAST SYSTEM MODEL HAS BEEN A BIT MORE CONSISTENT WITH SURFACE FRONT...BUT HAS SHOWN LARGE RUN TO RUN CHANGES IN UPPER PATTERN MAKING ITS SURFACE PATTERN SUSPECT. GIVEN THIS AND RECENT MODEL TRACK RECORDS...CONFIDENCE IN PRECIPITATION TIMING AND TEMPERATURE FORECAST QUITE LOW. EVEN IF FRONT GOES THROUGH...WOULD HAVE POTENTIAL FOR HIGH PLAINS STORMS TO ROLL DOWNHILL DURING THE NIGHT. RATHER THAN GOING LOW PROBABILITY OF PRECIPITATION EACH PERIOD THROUGHOUT THE ENTIRE EXTENDED...OPTED TO KEEP FORECAST DRY AND TEMPERATURES NEAR CLIMATOLOGY AS MUCH AS CONCENSUS WOULD ALLOW. -HOWERTON && .AVIATION...18Z TAFS KRSL/KSLN/KHUT/KICT/KCNU SCATTERED CONVECTION WILL DEVELOP THIS AFTERNOON IN ASSOCIATION WITH A WEAK COLD FRONT AND DISTURBANCE ALOFT MOVING ACROSS THE AREA. MVFR CIGS/VSBYS ARE STILL POSSIBLE ACROSS MUCH OF THE AREA THOUGH GENERALLY CONFINED IN AND NEAR SHOWERS AND STORMS THRU THIS EVENING. THERE ARE SOME DISCREPANCIES IN THE SHORT TERM MODELS WITH THE AMOUNT OF LOW LEVEL DRYING IN THE WAKE OF THE FRONT LATER TONIGHT INTO WEDNESDAY MORNING. RECENT MODEL PERFORMANCE HAS BEEN RATHER POOR OF LATE...SO HAVE RATHER LOW TO MODEST CONFIDENCE IN OUTER PERIOD OF THE TAFS. FOR NOW HAVE LEANED TOWARD THE NAM12 IN LESS AGGRESSIVE DRYING AND HANGING BACK SOME HIGHER SURFACE- BOUNDARY LAYER DEW POINTS/MOISTURE...AND WILL HEDGE WITH AT LEAST SOME MVFR FOG IN SOME AREAS AROUND DAWN.
