AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TOPEKA KS 350 PM CDT THU AUG 17 2006 DISCUSSION... UPPER AIR PATTERN REMAINS SIMILAR TO WEDNESDAY WITH UPPER RIDGE TO THE SOUTHEAST AND TROF IN THE PACIFIC NORTHWEST WITH VERY MOIST ATMOSPHERE IN BETWEEN. PRECIPITABLE WATER VALUES ARE AT TO ABOVE 150 PERCENT OF NORMAL IN THE TROPICAL PLUME. AREA PROFILES AND WATER VAPOR LOOP INDICATE A WEAK SHEAR ZONE ALOFT FROM WEST TEXAS INTO WESTERN KANSAS WITH PERHAPS EMBEDDED WAVES WORKING THEIR WAVE NORTHEAST. ANOTHER APPARENT CIRCULATION WAS OVER CENTRAL OKLAHOMA THOUGH NOT SUPPORTED BY PROFILER DATA. LOW LEVELS SOMEWHAT WARMER WITH MANY TEMPS AROUND 90F AT 19Z. SURFACE PATTERN IS RATHER DIFFUSE...BUT WEAK PRESSURE FALLS IN THE NORTHERN HIGH PLAINS AND DEEPER MIXING IN SOUTHERN PORTIONS OF THE LOCAL AREA HAVE CREATED WEAK MOISTURE CONVERGENCE OVER SOUTHEAST NEBRASKA AND NORTHEAST KANSAS. RADAR IMAGERY NEAR 20Z INDICATING PRECIPITATION BEGINNING TO DEVELOP FROM NORTHWEST KANSAS INTO SOUTHWEST IOWA AND ALSO IN SOUTHEAST KANSAS AND EXPECT THIS TO INCREASE IN COVERAGE EARLY ON AS CONVECTIVE TEMPERATURES ARE REACHED WITH WEAK FORCING AT THE SURFACE AND ALOFT...AIDED FURTHER BY LIKELY OUTFLOW BOUNDARIES. DEPENDING ON EXTENT OF EARLY CONVECTION...MAY SEE A BREAK IN THE LATE EVENING BEFORE WEAK LOW LEVEL JET KICKS IN WITH MOISTURE CONVERGENCE CENTERED OVER THE EASTERN KS/NE BORDER. BEST CHANCES OVERNIGHT SHOULD BE HERE WITH LESSER CHANCES TO THE SOUTHEAST IN LESSER MOISTURE. PRECIPITATION CHANCES HARD TO PIN DOWN FOR FRIDAY WITH POSSIBLE OUTFLOW BOUNDARIES...LINGERING UPPER TROF...AND STILL HIGH MOISTURE LEVELS. LOW LEVELS PROGGED TO WARM FURTHER OVER MUCH OF THE AREA SO POTENTIAL WILL BE THERE FOR HOTTER TEMPS BARRING SIGNIFICANT CLOUD COVER. THIS MAY BE THE CASE IN THE NORTH WERE BACKED LOW LEVEL FLOW MAY AID IN STRATUS FORMATION...BUT THINK THIS WILL REMAIN NORTH FOR THE DAY ANYWAY. HAVE HIGHEST POPS IN THE NORTH WHERE LOW LEVEL CONVERGENCE IS LIKELY TO BE MAXIMIZED. IN THE LATER PERIODS...THE TRANSITION IN THE FLOW PATTERN APPEARS WILL BE TAKING PLACE PER HPCS EXTENDED FCST DISCUSSION. FRONTAL BOUNDARY MVG THROUGH TMRW NIGHT WILL BRING A ROUND OF CONVECTION THAT COULD CONTAIN SOME ISOLATED SEVERE STORMS AND LOCALLY HEAVY RAIN...BUT IN FOLLOWING THE NAM, WILL BE ENDING PCPN FROM NW TO SE DURING SATURDAY. SCNDRY UPPER WAVE DEPICTED ON NAM MVG INTO SRN CWA LATE SATURDAY AFTN MAY PROVIDE ENUF IMPETUS FOR LINGERING PCPN THAT AREA...IF MOISTURE PROFILE ALLOWS. OTRW WOULD TEND TO WANT TO DROP PCPN CURRENTLY FCST SATURDAY EVENING THAT PTN OF THE STATE. FOR NOW AND CONTINUITYS SAKE, WILL MAINTAIN LOW POPS SRN CWA SATURDAY EVENING BUT END BY MIDNIGHT. NO PCPN BEYOND THAT FOR REST OF FCST...ALTHOUGH WITH TRANSITION TO NWRLY FLOW, COULD BE IN LINE FOR SOME MORE CONVECTION IN ABOUT A WEEK GIVEN GFSS DEPICTION OF A WAVE TOPPING RDG AND HEADING OUR WAY BY EARLY THURSDAY. GOOD CONTINUITY ON THE WAVE BUT REMAINS TO BE SEEN WHETHER IT WILL BE A WX PRODUCER FOR US. RE. TEMPERATURES...SEE A VERY SLOW MODERATION UP IN TEMPS BY MIDWEEK AS SFC HIGH RETREATS FROM THE AREA. LOWERED DEW POINTS A BIT FROM EARLIER FCST AS HIGH SHOULD SUPPRESS HIGHER VALUES SOUTH OF THE CWA. RETURN FLOW WILL TAKE A WHILE TO RECOVER THE HIGHER DEW POINTS. TIME WILL TELL. && .TOP WATCHES/WARNINGS/ADVISORIES...NONE. &&
