AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WICHITA KS 328 PM CDT FRI SEP 25 2009 .SYNOPSIS... CUT-OFF MID-UPR LOW THAT HAS BEEN CAMPING OUT OVER WRN NEBRASKA & NW KS THIS WEEK CONTINUES TO SPIN OVER THESE SAME AREAS THIS AFTERNOON. A MID LVL VORT LOBE ROTATING E AROUND SRN PERIMETER OF THE LOW IS PUSHING COLD FRONT E/SE TOWARD CNTRL KS...ALONG WHICH AREAS OF -SHRA & A FEW EMBEDDED TSRA DEVELOPED & ARE SPREADING E/NE ACROSS CNTRL & SC KS. SHRA/TSRA HAVE PRODUCED 0.10 TO 0.25 INCH RAINFALLS ALONG SW CORRIDOR OF KICT COUNTRY SINCE LATE THIS MORNING. .DISCUSSION... TONIGHT: PRIMARY FOCUS IS ON BEHAVIOR OF THE AFORE-MENTIONED MID-UPR LOW AS SHORT RANGE MODELS STILL ATTEMPT TO MOVE THE FEATURE SLOWLY E ACROSS NRN KS AS IT EVOLVES INTO AN OPEN WAVE SAT MORNING. WITH A NEARLY W-E ORIENTED UPR RIDGE PUNCHING E TOWARD THE NRN ROCKIES AM THINKING SHORT-RANGE MODELS MAY BE A BIT OPTIMISTIC WITH OPENING THIS UPR-DECK WAVE. REGARDLESS...AM CONFIDENT THAT WITH A DEEPENING SWLY FLOW ASSUMING A W/NW COMP THAT MUCH DRIER AIR WILL SURGE E ACROSS KICT COUNTRY TONIGHT & EARLY SAT. AS SUCH BEST CHANCES FOR MEASUREABLE RAINFALL THIS WEEKEND WILL OCCUR TONIGHT AS THE COLD FRONT SHOULD VACATE THE SE KS SAT MORNING. LEAVING A FAIRLY DRY AIRMASS IN ITS WAKE NICE WEATHER IS SLATED FOR THE REST OF THE WEEKEND WITH WARMING TREND COMMENCING SAT. ON SUN...A SUBTLE MID-LVL SHORTWAVE SHOULD CROSS KS BUT WITH A DRY AIRMASS IN PLACE NO MORE THAN A WINDSHIFT SHOULD SIGNAL THE PASSAGE OF THE ATTENDANT COLD FRONT. MOST CHALLENGING FACET OF THIS WEEKENDS FORECAST WILL BE DEGREE OF WARMUP ON SUN AS THE COLD FRONT APPROACHES. FOR NOW HAVE ASSIGNED 85-90F TO ALL AREAS WITH WARMEST/HOTTEST MAXES ASSIGNED TO SW CORRIDOR WHERE COMPRESSIONAL WARMING TO BE GREATEST. MON-TUE: ITLL BE A STELLAR START TO THE WORK-WEEK AS A STRONG RIDGE AXIS MOVES E ACROSS THE PLAINS...THEREBY RESULTING IN CLEAR-MOSTLY CLEAR WEATHER OVER ALL OF KICT COUNTRY. COOLEST LOWS ARRIVE TUE MORNING AS LOWS SETTLE INTO THE UPR 40S. WARMING TREND COMMENCES TUE AS SFC TROF DEVELOPING NEAR THE CO/KS BORDER INDUCES LWR-DECK FLOW TO ASSUME SE COMPONENT. WED-THU: WARM/WINDY WEATHER SLATED FOR ALL AREAS WED AS INTENSIFYING MID-UPR TROF MOVES E ACROSS NRN/CNTRL ROCKIES...THEREBY INDUCING PRE-FRONTAL SFC TROF TO DEEPEN CONSIDERABLY. WITH SUCH A PATTERN EVOLVING...THE RESULTING SLY FLOW WILL PROMOTE A VERY RICH MOISTURE SURGE APPEARING TO BE INJECTED WITH A HYPODERMIC. THIS HIGH-OCTANE FUEL WILL SET THE STAGE FOR ANOTHER ROUND OF STRONG-POTENTIALLY SVR TSTRMS FROM LATE WED NIGHT THRU THU EVE. CONSIDERING THE STRENGTH OF THE EVOLVING MID-UPR PATTERN...AM BIASING TOWARD THE FASTER GFS SOLUTION FOR THESE LATER PERIODS...WHICH DICTATES RAISING POPS INTO THE 30-40% RANGE FOR MOST AREAS THU & THU NIGHT. && .AVIATION...18Z TAFS KRSL/KSLN/KHUT/KICT/KCNU MAIN AVIATION CONCERN IS THE TIMING OF SHOWERS AND THUNDERSTORMS THIS AFTERNOON AND EVENING. UPPER LEVEL LOW CONTINUES TO SPIN IN NORTHWEST KANSAS. AS IT BEGINS TO BE PUSHED OUT OF THE AREA SHOWERS AND THUNDERSTORMS WILL DEVELOP. CURRENT WATER VAPOR IMAGERY IS SHOWING A PV ANOMALY IN NORTHWEST KS AND WILL BE SPINNING ITS WAY ACROSS THE AREA. THIS PV ANOMALY IS CURRENTLY CAUSING SHOWERS AND THUNDERSTORMS IN WESTERN AND SOUTH CENTRAL KANSAS. THESE STORMS ARE EXPECTED TO FORM FROM A KSLN TO KICT LINE AND WILL EFFECT THE TAF SITES WITHIN THE NEXT COUPLE OF HOURS. WITH DAY TIME HEATING AND THE PV ANOMALY SPINNING AROUND EXPECT THUNDERSTORMS AT KCNU AFTER 00Z. CEILINGS WILL REMAIN VFR FOR ALL SITES AND DUE TO NATURE OF THUNDERSTORMS KEPT WINDS AT VARIABLE.
