AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WICHITA KS 245 PM CDT MON AUG 7 2000 FCST FOCUS REMAINS TEMPS AND PRECIP CHCS IN HYBRID ZONAL/NW FLOW WILL USE A BLEND OF ETA LOW LEVEL PRESSURE/DEWPOINT FCSTS WITH BLEND OF ALL MODELS FOR PRECIP DEPICTIONS. LATEST WATER VAPOR SHOWS MAIN CORRIDOR OF WESTERLIES ACROSS NEB...IA...INTO N IL/WI...WITH STRONG SHORT WAVE RACING INTO THE DAKOTAS. PRESSURE FALLS ACROSS THE PLAINS IN ADVANCE OF THIS SYSTEM ARE ALLOWING SFC WINDS TO SLOWLY VEER TO THE SOUTH ACROSS THE AREA. MEANWHILE...KS REMAINS IN MOIST SUBTROPICAL FETCH WITH WEAK VORTS ROTATING AROUND WEAKNESS IN UPPER RIDGE. MOST OBVIOUS OF THESE NOW ACROSS EASTERN NM. AT 500 MB SMALL COLD POOL OF -10C INDICATED ACROSS WESTERN KS. AT 700 MB PROFILERS SHOW 20KTS OF SSW FLOW WITH NEUTRAL ADVECTION WITH STRONG MOISTURE ADVECTION INTO THE CWA. MEANWHILE...AT 850 MB EAST-WEST AXIS OF +15C DEWPOINTS EXTENDED FROM DDC INTO SW MO. CURRENT SFC MAP SHOWS THREE DISTINCT BOUNDARIES WITH THE FIRST ACROSS SOUTH-CENTRAL KS SEPARATING SSE FLOW FROM SSW FLOW WITH LOW 70 TDS JUST NORTH OF THIS WEAK BOUNDARY SLIGHTLY ELEVATED STORMS SEEM TO BE INITIALLY DEVELOPING ALONG THIS BOUNDARY AND MOVING NE. ANOTHER SFC BOUNDARY WAS LOCATED FROM NEAR SLN EAST ACROSS TOP/MKC WHERE MID 70 TDS ARE POOLING. MEANWHILE...LATEST VIS SAT PICS SHOW SFC BASED CU DEVELOPING ACROSS MUCH OF WESTERN OK IN RELATIVELY MOIST MIXED LAYER. BASED UPON WHAT IS HAPPENING AT THIS TIME AND THE COMBINATION OF SHEARED VORT AXIS ALONG WITH CONTINUED INSTABILITY AT THE SFC THIS EVENING AND ABOVE 800 MB OVERNIGHT WILL UP POPS FOR SOUTHERN KS WITH JUST THE SLIGHTEST CHCS CENTRAL KS. WILL KEEP POPS FOR SOUTH CENTRAL AND SOUTHEAST TOMORROW WITH MID LEVEL MOIST PLUME AND WEAK VORT AXIS STILL IN PLACE ALONG WITH MID LEVEL TEMPS OF LESS THAN 12C. LOOKING AT 850 THERMAL AXIS AND FCST 1000-850 THICKNESSES FEEL THAT WARMEST TEMPS WILL RE-ORGANIZE ACROSS CENTRAL KS TOMMORROW WITH NGM GUIDANCE LOOKING LIKE IT WILL VERIFY WITHIN 3 DEGREES. BY TOMORROW NIGHT NORTHERN PLAINS SYSTEM WILL DRAG SFC TROUGH TOWARD NORTHERN/NW KS. CONVECTIVE TEMPS LIKELY WILL BE REACHED HOWEVER AREAL COVERAGE REMAINS IN QUESTION AND WILL LEAVE GOING FCST DRY FOR NOW...WITH BETTER CHC TO FOCUS IN ON THIS AREA TONIGHT AND TOMORROW. BY WEDS...UPPER RIDGE WILL AGAIN TRY TO AMPLIFY ACROSS THE ROCKIES LEAVING KS IN TRANSITIONAL UPPER FLOW WHICH WILL BECOME SOMEWHAT NORTHWESTERLY. ANY STORM CHCS FOR THE AREA SHOULD THEN SHIFT TO AN EVENING/OVERNIGHT PATTERN WITH A BOUNDARY NEAR KS/NEB BORDER. HOWEVER AS USUAL THIS TIME OF YEAR CONFIDENCE IN EXACT EVOLUTION OF ANY STORMS IS LOW AND CURRENT FCST WILL REMAIN DRY FOR THIS REASON WITH AMPLE OPPORTUNITY TO INSERT STORMS NEXT 24 HOURS IF NEEDED. AS FOR TEMPS THERMAL RIDGE REMAINS PERSISTENT IN LOCATION WITH HOTTEST TEMPS LIKELY ACROSS CENTRAL KS...AS LONG AS BOUNDARY REMAINS NORTH OF AREA...WITH AROUND 100 OR SO SOUTH CENTRAL...MID 90S SE. EXTENDED...UPPER RIDGE ACROSS THE ROCKIES WITH WEAK NW FLOW ADVERTISED BY MRF WITH DRIER AND WARMER FCST INDICATED BY THE EURO MODEL. WILL FOLLOW HPC/S LEAD AND GO WITH MRF IDEA OF WEAK BOUNDARY SAGGING INTO THE AREA THURS/FRI TIME FRAME. WILL TWEAK TEMPS DOWN SLIGHTLY SAT AND WAIT ONE MORE DAY BEFORE INSERTING POPS. CO .ICT...NONE.
