Area forecast discussion, Aug 9, 3:39 PM CDT, 1 hour 23 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DODGE CITY KS 339 PM CDT SUN AUG 9 2009 .DISCUSSION... DAYS 1-2... A SHORTWAVE TROUGH WAS PASSING ACROSS THE NORTHERN AND CENTRAL PLAINS TODAY. A FEW THUNDERSTORMS WERE DEVELOPING JUST EAST OF DODGE CITY THIS AFTERNOON ALONG THE TRAILING COLD FRONT. THE MODELS DEVELOP AN MCS IN THE RIGHT REAR QUAD OF A JETLET TONIGHT AS THE LOW LEVEL JET STRENGTHENS ACROSS THE PANHANDLES INTO SOUTHWEST KANSAS. THE BEST CHANCE OF PRECIP SHOULD BE NORTH OF DDC. THE OUTFLOW BOUNDARY/COLD FRONT SHOULD BE NEAR OR SOUTH OF DDC BY MONDAY AFTERNOON. FAIRLY COLD UPPER LEVEL TEMPS ALONG WITH MOISTURE CONVERGENCE ALONG THE FRONT IN THE RIGHT REAR QUAD OF ANOTHER JETLET SHOULD ALLOW FOR MORE THUNDERSTORMS, ESPECIALLY IN THE AFTERNOON AND EVENING. THIS ACTIVITY WILL PROBABLY LINGER INTO MONDAY NIGHT, ESPECIALLY EAST OF DDC. THE OUTFLOW BOUNDARY/ RONT IS ADVERTISED TO PUSH INTO OKLAHOMA BY TUESDAY. LIGHT UPSLOPE FLOW IN OUR WESTERN COUNTIES AND INTO EASTERN CO MAY ALLOW FOR SOME STORM DEVELOPMENT IN OUR FAR WEST BY TUESDAY EVENING. THE WARMEST TEMPS WILL BE IN OUR SOUTHERN COUNTIES MONDAY WITH SOME PLACES REACHING NEAR 100F. EASTERLY UPSLOPE FLOW FURTHER NORTH AND SOME CLOUD COVER OUGHT TO KEEP TEMPS COOLER THERE. A FAIRLY UNIFORM AIRMASS WILL ARRIVE BY TUESDAY LEADING TO HIGHS IN NEAR 90 MOST PLACES. DAYS 3-7... INHERITED FORECAST IS IN PRETTY GOOD SHAPE FOR THE PERIOD TUESDAY NIGHT THROUGH THE EARLY PART OF NEXT WEEKEND. AM GENERALLY FOLLOWING THE ECMWF, CANADIAN AND 06Z GFS DETERMINISTIC SOLUTIONS FOR THIS FORECAST. THE 12Z GFS WAS LARGELY DISCOUNTED AS IT WAS SHOWING A TOTALLY DIFFERENT PATTERN FOR THE END OF THE WEEK VERSUS ITS PREVIOUS RUN AND THE ECMWF/CANADIAN. THE 12Z GFS TOTALLY LOSES THE PACIFIC NORTHWEST/NORTHERN ROCKIES AND PLAINS DEEP TROUGH SCENARIO. AM LEERY OF SUCH A RADICAL DEVIATION FROM APPEARED TO BE AN OTHERWISE RATHER CONSISTENT MID-UPPER HEIGHT/KINEMATIC PATTERN FROM THE OTHER GLOBAL SPECTRAL MODEL SOLUTIONS. IN THE DAILIES...WILL SEE A GRADUAL WARM-UP FROM WEDNESDAY TO SATURDAY. THE ONLY CHANGE OF NOTE WAS TO INCREASE OVERNIGHT LOWS AT THE END OF THE WEEK TO NEAR 70/LOWER 70S GIVEN THE LIKELIHOOD OF INCREASED NOCTURNAL SOUTHERLY WINDS AS A DEEP LEE TROUGH DEVELOPS IN ADVANCE OF ANOTHER DECENT UPPER LEVEL TROUGH. AM GOING WITH 15 TO 20 POPS ACROSS MAINLY WESTERN 6 DDC FA COUNTIES EACH EVENING TUESDAY-THURSDAY AS THERE SHOULD BE THE TYPICAL EASTERN COLORADO SHOWER/THUNDERSTORM DEVELOPMENT ON SOUTH-SOUTHEASTERLY LOW LEVEL FLOW AND MEDIOCRE WEST-NORTHWEST OR NORTHWEST FLOW IN THE MID AND UPPER LEVELS. THE ECMWF SUGGESTS A WEAK UPPER LEVEL JET STREAK ROUNDING THE CENTER OF THE MID LEVEL RIDGE WHICH MAY ENHANCE CONVECTIVE DEVELOPMENT WEDNESDAY AND/OR THURSDAY LATE AFTERNOON/EVENING ACROSS HIGH PLAINS. THE BIG TROUGH THEN BEGINS TO SHOW UP BY FRIDAY WITH SOUTHWESTERLY FLOW ALOFT DEVELOPING SOUTHWARD DOWN THE ROCKIES IN ADVANCE. THIS WOULD ACTUALLY ARGUE FOR A HOTTER/DRIER COUPLE OF DAYS FRIDAY/SATURDAY DEPENDING ON HOW FAST AND DEEP THE SYSTEM DEVELOPS WELL TO THE NORTHWEST. WILL NOT BE CARRYING ANY POPS YET IN THE DAY 5-7 PERIOD...HOWEVER A FRONT SHOULD WORK ITS WAY SOUTH AS THIS TROUGH SHIFTS EAST...WHICH WOULD INCREASE CHANCES FOR PCPN AT THE END OF THIS FORECAST PERIOD. && .PRELIMINARY POINT TEMPS/POPS...
