AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DODGE CITY KS 315 PM CDT FRI SEP 11 2009 .DISCUSSION... DAYS 1-2... A VERY COMPLEX, BLOCKY FLOW REGIME WILL PREVAIL ACROSS THE CENTRAL UNITED STATES INTO EARLY NEXT WEEK. THE BIGGEST FORECAST CHALLENGES ARE EXTENT OF THUNDERSTORMS TONIGHT AND EVOLUTION OF LIGHT RAIN/DRIZZLE IN PERSISTENT WEAK ISENTROPIC LIFT BEHIND THE FRONT SATURDAY. EVOLUTION OF WEAK UPPER LEVEL TROUGHS ROTATING AROUND THE SOUTHERN PLAINS GYRE ADDS UNCERTAINTY TO TIMING AND COVERAGE OF RAINFALL ON SUNDAY. TEMPERATURES WILL BE HEAVILY DEPENDENT ON CLOUD COVER AND PRECIPITATION. COOL AIR SPILLED SOUTHWARD MORE QUICKLY THAN FORECAST BY THE MODELS IN THE LEE OF THE ROCKIES THIS MORNING. A SURFACE LOW PRESSURE SYSTEM SOUTHWEST OF ELKHART HAS MAINTAINED A SHARP PRESSURE GRADIENT ACROSS EASTERN COLORADO. THE MAY BE AIDED BY WEAK DIVERGENCE IN THE ENTRANCE REGION OF THE VERY MODEST JET STREAK EVIDENT ON SATELLITE IMAGERY FROM NORTHEAST COLORADO INTO SOUTHEAST NEBRASKA. THE CYCLONE MAY BE PARTIALLY THERMAL IN CHARACTER, AS WELL. THE MID LEVEL WARM PLUME WILL DELAY INITIATION OF THUNDERSTORMS IN THE FRONTAL ZONE IN WESTERN KANSAS THIS AFTERNOON, BUT THUNDERSTORMS SHOULD DEVELOP BY LATE AFTERNOON AND GRADUALLY PROPAGATE SOUTHEAST DURING THE EVENING AND NIGHTTIME HOURS. INSTABILITY IS MODEST ALONG THE FRONTAL ZONE, AND WINDS THROUGH THE ATMOSPHERE WILL CONTINUE TO BE WEAK. AS SUCH, THE POTENTIAL FOR ORGANIZED SEVERE WEATHER IS MINIMAL, ALTHOUGH A PULSY MARGINAL HAIL OR WIND EVENT IS NOT IMPOSSIBLE. THE NUMERICAL GUIDANCE IS IN REASONABLE AGREEMENT ON EVOLUTION OF THE BLOCKY FLOW OVER THE UNITED STATES THROUGH THE MIDDLE OF NEXT WEEK. THE GFS SEEMED TO HAVE THE BEST HANDLE ON THE MAGNITUDE OF THE COOL SURGE DOWN THE HIGH PLAINS THIS AFTERNOON AND LARGELY WAS USED FOR GRID MODIFICATIONS. THE COLD FRONT ENTERING NORTHERN KANSAS THIS AFTERNOON WILL BECOME INCREASINGLY DIFFUSE AS IT PROPAGATES SOUTHWARD TONIGHT, AND CONVERGENCE ALONG THE BOUNDARY WILL WEAKEN AS IT PROGRESSES INTO PREVAILING EAST TO NORTHEAST LOW LEVEL FLOW AROUND THE BROAD SOUTHERN PLAINS GYRE. THUNDERSTORM ACTIVITY IN THE WEAKENING FRONTAL ZONE LIKELY WILL DIMINISH BY LATE EVENING IN WESTERN KANSAS. THE UPPER LEVEL CYCLONE OVER NORTH DAKOTA THIS AFTERNOON WILL MOVE INTO EASTERN WYOMING BY SATURDAY EVENING AND GRADUALLY MOVE BACK NORTHWARD INTO SOUTHWEST SASKATCHEWAN BY MONDAY MORNING. PRESSURES WILL FALL IN THE LEE OF THE ROCKIES AS THE UPPER LEVEL CYCLONE MOVES BACK TO THE WEST...AND EASTERLY UPSLOPE LOW LEVEL FLOW WILL PREVAIL ACROSS KANSAS SATURDAY AND SUNDAY. ISENTROPIC LIFTING OF THE SATURATED POST FRONTAL AIR OVER THE DOME OF COOL AIR IN THE HIGH PLAINS WILL SUPPORT WIDESPREAD LIGHT RAIN AND DRIZZLE SATURDAY...ESPECIALLY FROM DODGE CITY WEST TO THE COLORADO BORDER. TEMPERATURES MAY NOT RISE ABOVE THE LOWER 60S IN WEST CENTRAL KANSAS SATURDAY AFTERNOON. LOW LEVEL WINDS WILL VEER MORE TOWARD THE SOUTHEAST IN WESTERN KANSAS SATURDAY NIGHT, WHILE NORTH TO NORTHEAST WINDS AROUND THE TEXAS CYCLONE CONTINUE. THE RESULT WILL BE DEVELOPMENT OF WEAK LOW LEVEL DIVERGENCE AND SUBSIDENCE IN WESTERN KANSAS. RAIN CHANCES WILL DIMINISH BY SATURDAY EVENING, AND THERE MAY EVEN BE SOME BREAKS IN THE CLOUD COVER. IF CLOUDINESS DOES DECREASE, FOG MAY DEVELOP LATE SATURDAY NIGHT INTO SUNDAY MORNING IN WESTERN KANSAS. A MINOR UPPER LEVEL TROUGH EVIDENT ON SATELLITE IMAGERY NEAR THE EAST TEXAS GULF COAST WILL ROTATE AROUND THE SOUTHERN PLAINS GYRE AND APPROACH SOUTH CENTRAL KANSAS BY SUNDAY MORNING. WEAK UPWARD VERTICAL MOTION IN ADVANCE OF THE UPPER LEVEL TROUGH SHOULD BE SUFFICIENT TO SUPPORT SCATTERED SHOWERS IN SOUTH CENTRAL KANSAS SUNDAY MORNING, AND THE SHOWERS WILL SPREAD WESTWARD DURING THE DAY SUNDAY. RAIN CHANCES WILL REMAIN LOW IN FAR WESTERN KANSAS WHERE GENERALLY DIVERGENT LOW LEVEL FLOW WILL CONTINUE. TEMPERATURES SUNDAY WILL BE COOLEST IN THE EASTERN PART OF THE FORECAST AREA, WHERE CLOUD COVER WILL BE MOST PERSISTENT. DAYS 3-7... THE LATER PERIODS WILL BE CHARACTERIZED BY WEAKNESS IN THE UPPER FLOW. ONE FORECAST ISSUE WILL BE THE UPPER SYSTEM OVER CENTRAL AND SOUTHEAST TEXAS THAT IS PROGGED TO DRIFT NORTH AND A LITTLE WEST. JUST HOW FAR WEST IT GETS WILL PLAY A HUGE ROLE ON THE SENSIBLE WEATHER ACROSS AT LEAST MY SOUTHEAST CWA. THE LATEST ECMWF APPEARS TO BE THE FARTHEST WEST. I HAVE KEPT SOME LOW POPS OR MONDAY ACROSS THE SOUTHEAST 1/2 OF MY AREA BUT IF THE SYSTEM IS A LITTLE FARTHER WEST THESE WILL HAVE TO BE RAISED BY SUBSEQUENT SHIFTS. TEMPERATURES, ESPECIALLY ON MONDAY WILL BE INFLUENCED BY THE PROXIMITY OF THIS SYSTEM AND HAVE OPTED FOR MID 70S ACROSS MOST OF THE AREA. BY MID WEEK THE UPPER RIDGE BUILDS THROUGH THE ROCKIES INTO CANADA AS FAIRLY STRONG FLOW ENTERS THE PACIFIC NORTHWEST. EVENTUALLY THERE SHOULD BE A STRONG DIGGING SYSTEM INTO THE GREAT LAKES THAT WILL UNLEASH A SIGNIFICANT COLD AIRMASS (RELATIVELY SPEAKING) AND THIS MAY BE AS EARLY AS THE WEEKEND, WHICH WOULD ALSO BE THE NEXT DECENT CHANCE FOR PCPN AFTER THE FIRST OF THE WEEK. MOST OF THE MODELS, BOTH DETERMINISTIC AND ENSEMBLE MEANS, HINT AT THIS SCENARIO. THERE IS ALSO A POSSIBILITY OF ANOTHER UPPER LEVEL SYSTEM CUTTING UNDERNEATH THE AMPLIFYING RIDGE AND DRIFTING OUT OF THE CENTRAL ROCKIES. IF THIS DOES HAPPEN IT WOULD BE LATE IN THE WEEK BUT AT THIS POINT I WONT DO MUCH TO FORECAST...ITS JUST SOMETHING THAT COULD IMPACT THE WEATHER LATER IN THE FORECAST PERIOD. && AVIATION... THE ADVERTISED FRONT WILL BE LITTLE DELAYED AS THE PROGRESS HAS SLOWED CONSIDERABLY THIS AFTERNOON. THERE STILL APPEARS TO BE A DECENT CHANCE FOR TSRA DEVELOPING ALONG THE FRONT BY EVENING BUT THE GCK TERMINAL MAY BE THE LOCATION WITH THE GREATEST CHANCE. OTHERWISE, CLOUDS WILL CONTINUE WITH CIGS GENERALLY IN THE MVFR RANGE. AT THIS TIME THE CHANCE FOR LOW VSBYS UNDER 5SM DO NOT APPEAR LIKELY. && .PRELIMINARY POINT TEMPS/POPS...
