Area forecast discussion, Jul 13, 6:44 PM CDT, 11 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WICHITA KS 644 PM CDT FRI JUL 13 2012 .UPDATE... UPDATED ABOUT AN HOUR AGO TO ADJUST PRECIP THIS EVENING. SMALL CLUSTER OF STORMS CONTINUES TO DIVE SOUTH OVER PORTIONS OF SOUTH CENTRAL KS. THIS AREA OF STORMS WILL CONTINUE TO DIVE SOUTH THIS EVENING AND SHOULD BE OUT OF THE AREA BY 9 PM. DID LINGER SOME ISO STORM CHANCES OVER CENTRAL KS DUE TO VIS SATELLITE STILL SHOWING SOME POCKETS OF TOWERING CU. MEANWHILE WENT AHEAD AND REMOVED POPS FOR SOUTHEAST KS. CONFIDENCE IS HIGH THAT BY 9 PM THE PRECIP WILL BE OUT OF THE FORECAST AREA. && .AVIATION...00Z TAFS KRSL/KSLN/KHUT/KICT/KCNU MAIN AVIATION CONCERN WILL BE STORM CHANCES THIS EVENING. A SMALL CLUSTER OF STORMS SOUTHWEST OF WICHITA WILL CONTINUE TO PUSH SOUTH THIS EVENING AND WILL BE OUT OF THE FORECAST AREA BY 9 PM. WITH THIS AREA OF STORMS WELL SOUTH OF KICT...WENT AHEAD AND TOOK OUT OF THE KICT TAF. THEREFORE CURRENTLY RUNNING WITH VFR CONDITIONS AREAWIDE THROUGH THIS TAF PACKAGE AS THE BULK OF THE UPPER ENERGY CONTINUES TO PUSH SOUTH AND EAST LEAVING THE FORECAST AREA HOT AND DRY. LAWSON && .PREV DISCUSSION... /ISSUED 318 PM CDT FRI JUL 13 2012/ DISCUSSION... FORECAST CHALLENGES: MAIN ISSUE FOR THIS FORECAST IS DETERMINING MAX TEMPERATURES FOR THE NEXT FEW DAYS AS MODEL GUIDANCE HAS BEEN TOO LOW THE PAST COUPLE OF DAYS. THE EXTENDED PART OF THE FORECAST IS A TOSS UP WITH ANY WEAK WAVES THAT MAY MOVE THROUGH THE AREA. SYNOPSIS: A RIDGE ACROSS THE ROCKIES WILL BEGIN ITS EASTWARD SLIDE AS A TROUGH STRETCHING FROM MINNESOTA TO LOUISIANA WILL PROGRESS TO DEVELOP A NORTHEASTWARD SLANT. THE NORTHERN PORTION OF THIS TROUGH WILL REMAIN OVER THE EASTERN CONUS FOR A GOOD PORTION OF THE FORECAST PERIOD. THIS TROUGH HAS DEVELOPED SHOWERS AND THUNDERSTORMS AS IT DRAPES THROUGH THE CENTRAL UNITED STATES. THERE IS AN ASSOCIATED DOMINO EFFECT WITH DEVELOPMENT ON THE OUTFLOW BOUNDARIES OF THESE STORMS IN THE UNSTABLE ATMOSPHERE TO THE SOUTH. TONIGHT TO TUESDAY: A TROUGH WILL CONTINUE TO DEEPEN ALONG THE WESTERN CONUS IN THIS TIME FRAME...BUT THE RIDGE SHALL REMAIN OVER THE AREA. THERE IS A SLIGHT BREAKDOWN IN THE RIDGE ON SUNDAY WHICH WILL SCRUNCH THE HIGH TO THE SOUTHEAST AND SOUTHERN PLAINS. HOWEVER THE MAIN ENERGY ASSOCIATED WITH THIS SYSTEM WILL STAY TO THE NORTHERN PLAINS AND WESTERN CONUS. TEMPERATURES SHOULD STAY ABOVE NORMAL THROUGH THE FORECAST PERIOD WITH VALUES NEAR 100. EVEN SIDING ON THE WARM SIDE OF THINGS ACCORDING TO MODEL GUIDANCE WITH LACKING GROUND MOISTURE...THIS DOES NOT ACCOUNT FOR DEVELOPMENT OF CUMULUS UPON REACHING CONVECTIVE TEMPERATURES. THERE IS SOMEWHAT OF A LIMITED MOISTURE FIELD...BUT CANNOT RULE OUT VERY ISOLATED CHANCES IN THE AFTERNOON HOURS WHICH HAS OCCURRED THIS WEEK IN THAT SAME TIME PERIOD GIVEN INSTABILITY. MODEL GUIDANCE HAS NOT HAD THE BEST HANDLE ON TEMPERATURES FURTHER COMPLICATING WHAT THE MAX TEMP WILL REACH FOR THE DAY. WEDNESDAY TO FRIDAY: THERE DOES APPEAR TO BE A BIT OF QUESTION FOR THIS TIME PERIOD AND ANY WAVES THAT MAY CREEP IN FROM THE ROCKIES OFF OF THE MAIN TROUGH MENTIONED ABOVE. THE INFLUENCE OF ANY OF THESE WAVES IS QUESTIONABLE BASED ON MODEL DISCREPANCIES. IT APPEARS THERE WILL BE A FRONTAL PASSAGE FOR THE LATTER PART OF THE WEEK...HOWEVER TIMING IS IN THE AIR. PRECIP CHANCES FOR WEDNESDAY IN SOUTHEAST KANSAS WERE DECREASED...AND IT LOOKS LIKE BETTER CHANCES WILL BE IN WESTERN KANSAS ON WEDNESDAY EVENING. THEREFORE ANY CHANCES IN THE CWA REMAIN QUESTIONABLE. TEMPERATURES WILL MODERATE AROUND 100 SIMILAR TO THE FIRST PART OF THE FORECAST. ONLY MINOR TWEAKS AND ADJUSTMENTS WERE NEEDED TO THE ONGOING FORECAST. PEARCE AVIATION... MAIN CONCERN IS THUNDERSTORM POTENTIAL THIS AFTERNOON. ISOLATED-SCATTERED STORMS CONTINUE TO DEVELOP IN THE VICINITY OF OUTFLOW BOUNDARY FROM THIS MORNINGS PRECIPITATION OVER NE KS. BEST COVERAGE HAS BEEN IN SOUTHEAST KS...AND EXPECT THIS TO PERSIST GIVEN SOME SUPPORT ALOFT. RECENTLY AMEND KCNU TO INCLUDE TEMPORARY THUNDERSTORM IN FORECAST. CHANCES TOO LOW TO MENTION AT KSLN/KICT FOR NOW. EXPECT THESE TO BE DIURNALLY MODULATED...WITH VFR CONDITION AFTER SUNSET AT ALL SITES. -HOWERTON && .PRELIMINARY POINT TEMPS/POPS...
