Area forecast discussion, Jul 21, 3:40 PM CDT, 4 hours 1 minute before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DODGE CITY KS 340 PM CDT THU JUL 21 2011 .SYNOPSIS... ON THE SYNOPTIC SCALE...THE UPPER LEVEL HIGH CONTINUED TO BE CENTERED OVER THE MID MISSISSIPPI VALLEY WITH INFLUENCE EXTENDING WESTWARD TOWARD THE SOUTHERN/CENTRAL PLAINS. A JET STREAK TIED TO STRONG SHORTWAVE TROUGH WAS LOCATED OVER THE NORTHEASTERN GREAT PLAINS NOSING INTO SOUTHWEST ONTARIO. ADDITIONAL PACIFIC JET STREAM ENERGY WAS MOVING INTO THE PACIFIC NORTHWEST REGION...REINFORCING THE COOL TEMPERATURES ACROSS THIS REGION OF THE CONUS. MID LEVEL MOISTURE 500-700MB WAS FOUND EXTENDING FROM NORTHERN MEXICO INTO WESTERN ARIZONA/EASTERN NEW MEXICO AND NORTHWARD INTO COLORADO AROUND THE WESTERN PERIPHERY OF THE LARGE UPPER HIGH. A SMALL MESOSCALE CONVECTIVE SYSTEM (MCS) WAS MOVING OUT OF FAR EASTERN NEBRASKA INTO WESTERN IOWA LEAVING IN ITS WAKE A SMALL SURFACE HIGH. CONVERGENCE WAS ENHANCED IN THE LOW LEVELS SOUTH OF THIS MESOSCALE HIGH INTO NORTHERN KANSAS. THE HEAT PLUME AT THE SURFACE (WITH TEMPERATURES OF 102 TO 105F) EXTENDED FROM SOUTHWEST KANSAS NORTHEASTWARD TO THE FRONT NEAR MANHATTAN/TOPEKA KANSAS. ANOTHER CONVERGENCE AXIS...ALBEIT WEAK...EXTENDED SOUTHWEST FROM THE FRONT FROM NEAR WAKEENEY/HAYS SOUTHWEST INTO WEST CENTRAL KANSAS. AGGRESSIVE CUMULUS DEVELOPMENT WAS UNDERWAY AS OF 20Z WITH A FEW INCIPIENT THUNDERSTORMS JUST SOUTH OF INTERSTATE 70 SOUTH OF WAKEENEY AND HAYS. && .DISCUSSION... DAYS 1-2... THUNDERSTORMS WILL CONTINUE TO FORM DURING THE LATE AFTERNOON AND THROUGH THE EVENING HOURS FROM WHERE CONVERGENCE WAS MOST ENHANCED NEAR INTERSTATE 70 SOUTHWESTWARD ALONG THE CONVERGENCE AXIS. THE RUC, NAM, AND HRRR MODELS ALL SUGGEST THIS CONVECTIVE SIGNAL THROUGH THE EVENING HOURS AND CONTINUING INTO THE OVERNIGHT HOURS BEFORE DIMINISHING. WILL BE GOING WITH 30 TO 40 POPS GENERALLY NORTHWEST OF A MEADE TO DODGE CITY TO LARNED LINE. ORGANIZED COLD POOL GENERATION WILL LEAD TO ADDITIONAL STORMS THROUGH THE EVENING BEFORE DISSIPATION BEGINS AROUND 04 TO 06Z OR SO. HAVE LOWERED THE LOW TEMPERATURES INTO THE LOWER 70S IN THE NORTHERN CWA WHERE THUNDERSTORMS ARE MOST LIKELY TO IMPACT TEMPERATURES THIS EVENING/OVERNIGHT. SOUTH WINDS WILL RESUME PRETTY MUCH EVERYWHERE ACROSS THE DDC FA TOMORROW WITH REMNANT CONVECTIVE OUTFLOW BOUNDARIES WASHING OUT. ANOTHER DAY OF HIGHS IN THE 102 TO 105 RANGE IS EXPECTED AND WILL CONTINUE THE EXCESSIVE HEAT WARNING IN THE FAR EASTERN COUNTIES OF THE DDC FA (ELLIS TO STAFFORD TO BARBER COUNTIES). AM ALSO EXPECTING A REPEAT OF DIURNALLY DRIVEN CONVECTION FRIDAY LATE AFTERNOON/EVENING IN PRETTY MUCH THE SAME AREA NORTHWESTERN HALF/THIRD OF THE FORECAST AREA...WITH MUCH OF THE SAME AREAS SEEING THE GREATEST CHANCE FOR STORMS AS WELL AS THE SAME GENERAL AREAS SEEING LITTLE OR NO CHANCE FOR PRECIPITATION (PARTICULARLY CLOSER TO SOUTH-CENTRAL KANSAS ALONG THE OKLAHOMA BORDER). ANOTHER HOT ONE IS EXPECTED SATURDAY AHEAD OF THE NEXT COLD FRONT PUSH MOVING INTO NEBRASKA. WILL BE GOING WITH HIGHS 105 TO 108 ACROSS MUCH OF THE FORECAST AREA AND WILL BE EXTENDING THE EXCESSIVE HEAT WARNING INTO SATURDAY AS A RESULT FOR THE FAR EASTERN DDC FA...FOR CONTINUED DAILY MEETING/EXCEEDING OF THE 105 HEAT INDEX CRITERIA. WILL BE KEEPING PRECIPITATION CHANCES BELOW 15-20 PERCENT SATURDAY WITH THE MAIN FOCUS FOR PRECIPITATION UP IN NEBRASKA ALONG THE NEXT COLD FRONT. BETTER CHANCE FOR PRECIPITATION IN THE NORTHERN COUNTIES WITH THIS NEXT FRONT WILL BE AFTER THE DAYTIME HOURS SATURDAY. DAYS 3-7... THE UPPER LEVELS OF THE ATMOSPHERE IN THE EXTENDED AN BE DESCRIBED BY A LARGE UPPER LEVEL HIGH DOMINATING MUCH OF THE SOUTHERN UNITED STATES AND A TROUGH OF LOW PRESSURE FOUND ACROSS THE WESTERN UNITED STATES. ALSO...A FEW SHORTWAVE TROUGHS ARE EXPECTED TO MOVE UP AND OVER THIS HIGH ACROSS THE NORTHERN PLAINS. TOWARDS THE SURFACE...A FRONTAL BOUNDARY WILL BE FOUND ACROSS THE KS/NE BORDER SATURDAY NIGHT BEFORE MOVING BACK NORTH AS A WARM FRONT SUNDAY. A FEW STORMS WILL BE POSSIBLE ACROSS NORTHERN KANSAS SUNDAY MORNING...OTHERWISE PARTLY CLOUDY SKIES WILL PREVAIL. SURFACE HIGH PRESSURE WILL BUILD ACROSS THE AREA SUNDAY INTO MONDAY LEAVING THE ENTIRE FORECAST AREA UNDER MOSTLY CLEAR SKIES AND DRY CONDITIONS. ANOTHER COLD FRONT IS THEN PROGGED TO MOVE DOWN FROM THE NORTHERN PLAINS TUESDAY BEFORE STALLING OUT ACROSS THE KS/NE BORDER ON WEDNESDAY. ONCE AGAIN...A FEW STORMS WILL BE POSSIBLE ACROSS NORTHERN PORTIONS OF OUR FORECAST AREA. THE REMAINDER OF OUR FORECAST AREA WILL MOST LIKELY EXPERIENCE CONTINUED DRY CONDITIONS. WINDS THROUGHOUT THE EXTENDED PERIOD WILL GENERALLY BE FROM THE SOUTH ALLOWING FOR WARM AIR TO BE PUMPED IN FROM THE SOUTH. ABOVE NORMAL TEMPERATURES WILL CONTINUE THROUGHOUT THE EXTENDED PERIOD WITH HIGHS IN THE LOWER TO MID 100S EACH DAY. MODELS ARE SUGGESTING EVEN WARMER TEMPERATURES ON WEDNESDAY WITH HIGHS REACHING INTO THE MID TO UPPER 100S IN SOME PLACES. LOWS WILL GENERALLY BE IN THE 70S WITH UPPER 70S FOUND ACROSS SOUTH CENTRAL KANSAS. && .AVIATION... A STATIONARY FRONT WILL BE FOUND ACROSS NORTHERN KANSAS THIS EVENING BEFORE MOVING BACK TO THE NORTH AS A WARM FRONT TOMORROW. THUNDERSTORMS WILL BE POSSIBLE ACROSS THE HAYS TERMINAL THIS EVENING BRINGING BRIEF MVFR CONDITIONS DUE TO LOWERED VISIBILITY. OTHERWISE VFR CONDITIONS WILL PREVAIL.
