000 FXUS63 KDDC 250906 AFDDDC AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DODGE CITY KS 306 AM CST WED NOV 25 2009 .DISCUSSION... DAYS 1-2... THE 00Z 500 MB ANALYSIS SHOWED A CLOSED LOW OVER EASTERN IOWA AND MOVING OFF TO THE EAST AS ANOTHER VIGOROUS SHORTWAVE TROUGH WAS DIVING SOUTH SOUTHEASTWARD ACROSS THE NORTHERN HIGH PLAINS. THIS SYSTEM WAS GENERATING SOME LIGHT PRECIP ACROSS WEST CENTRAL NEBRASKA AT 08Z THIS MORNING AS SOME METAR SITES ACROSS CENTRAL NEBRASKA WERE REPORTING SOME SPRINKLES WHILE SOME LIGHT SNOW OR FLURRIES WERE BEING DETECTED FARTHER WEST. THIS WAVE WILL MOVE RAPIDLY THROUGH CENTRAL AND EASTERN KANSAS THROUGH 18Z. THINK WE WILL SEE SOME LIGHT RAIN OR SNOW ACROSS THE NORTHEAST THIRD OF THE CWA BETWEEN 12 AND 18Z. GIVEN THE RAPID MOVEMENT AND LIGHT NATURE OF THE PRECIP DO NOT EXPECT MUCH IN THE WAY OF MEASURABLE PRECIP SO WILL KEEP POPS AROUND OR LESS THAN 20 PERCENT. AS THE SYSTEM ROLLS ON THROUGH WE SHOULD SEE CLOUDS DECREASING FROM NORTH TO SOUTH BY LATE MORNING WITH SKIES BECOMING MAINLY SUNNY THIS AFTERNOON. WINDS WILL BECOME GUSTY FROM THE NORTH AT 15 TO 25 MPH THIS MORNING BUT EXPECT WINDS TO DECREASE BY MID AFTERNOON AS THE SURFACE PRESSURE RIDGE MOVES IN. SKIES WILL BE MOSTLY CLEAR TONIGHT AND WITH WINDS BECOMING LIGHT AND VARIABLE WE SHOULD SEE TEMPERATURES FALLING INTO THE LOW/MID 20S. THANKSGIVING DAY SHOULD BE A FAIRLY PLEASANT DAY ACROSS SOUTHWEST KANSAS AS UPPER LEVEL RIDGING BUILDS BACK OVER THE CENTRAL PLAINS. INCREASING THICKNESS VALUES SHOULD HELP TEMPERATURES CLIMB INTO THE UPPER 50S TO AROUND 60 WITH FAIRLY LIGHT WINDS. DAYS 3-7... THE EXTENDED FORECAST REMAINS IN PRETTY GOOD SHAPE. MAIN QUESTIONS ARE THE POTENTIAL FOR PRECIP SUN INTO MON AND THE EXTENT OF THE POSSIBLE COLD AIR INTRUSION NEXT WEEK. A TRANSIENT RIDGE WILL BE OHD ON FRI AND FORECASTED THERMODYNAMIC PROFILES WITH SUFFICIENT MIXING CONTINUE TO SUPPORT HIGHS IN THE 60S OVER SW KANSAS. THE RIDGE MOVES EAST ON SAT AS A TROF DIGS INTO THE WESTERN CONUS. TEMPS WILL BE TRICKY AS A BACKDOOR FRONT IS ADVERTISED TO MOVE THROUGH SW KS ON SAT. THE TIMING OF THE FRONT WILL BE IMPORTANT FOR TEMP FORECAST. WILL KEEP WHAT WE HAVE NOW (HIGHS IN THE 50S) BUT IT COULD BE MUCH COOLER IF THE MODELS VERIFY. SUNDAY WILL DEFINITELY BE COOLER AS THE TROF SETTLES INTO THE 4-CORNERS REGION. WE COULD EVEN SEE SOME PRECIP SUN IF THE SOMEWHAT SLOWER AND MORE CLOSED OFF EC VERIFIES. THE GFS AND GEM REMAIN DRY ON SUNDAY (AND MORE PROGRESSIVE WITH THE TROF IN GENERAL) AND WITH SUCH INCONSISTENCIES, WILL KEEP THE SLIGHT CHANCE POPS FOR SUN. MON AND TUE WILL FEATURE A TROF ACROSS THE CENTER OF THE COUNTRY AND WILL PROBABLY BE DRY OVER SW KANSAS. WHILE THIS PATTERN COULD LEND ITSELF TO A COLD AIR INTRUSION, DOWNSLOPING MAY RETARD THE COOLING. GIVEN THESE UNCERTAINTIES WILL NOT CHANGE THE NEXT WEEK FORECAST OTHER THAN MINOR COSMETIC TWEAKS. AS WE GET OUT INTO WEEK 2, THE MODELS STILL ADVERTISE A GOOD CHANCE FOR COLD AIR PLUNGING SOUTHWARD BUT, OF COURSE, THIS REMAINS TO BE SEEN. -WRIGHT && AVIATION... WE ARE WATCHING A SHORTWAVE AND ASSOCIATED BAND OF -SN MOVING SOUTH THROUGH NEBRASKA ATM. PURE RADAR EXTRAPOLATION BRINGS -SN TO KHYS BY 25/12-15Z BUT THE MODELS TEND TO DECREASE THE LIFT AS IT MOVES SOUTH. WILL MONITOR TRENDS BUT MAY HAVE TO INSERT -SN AND MVFR CIGS/VIS INTO THE TAFS AT LEAST AT KHYS IN THE NEXT HOUR OR TWO. OTHERWISE, THIS SHORTWAVE WILL PUSH THROUGH ANOTHER COLD FRONT AND REINFORCING SHOT OF COLD AIR ALONG WITH INCREASED WIND. WINDS WILL SHIFT FROM WEST TO NNW AND INCREASE AS HIGH PRESSURE BEHIND THE WAVE ARRIVES LATER THIS MORNING - PROBABLY BY 25/12Z AT KHYS AND KDDC/KGCK SHORTLY THEREAFTER. OTHER THAN THE POTENTIAL FOR -SN EARLY THIS AM, VFR CONDS LIKELY THROUGH TODAY. -WRIGHT && .PRELIMINARY POINT TEMPS/POPS...
