The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Norman, OK wrote its last area forecast discussion before the first event at Jul 11, 2:13 PM CST, 32 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORMAN OK 313 PM CDT THU JUL 11 2013 .DISCUSSION... THE FORECAST IS SOMEWHAT MUDDLED THIS PERIOD. WE CONTINUE TO SEE ISOLATED TO WIDELY SCATTERED SHOWERS AND STORMS THIS AFTERNOON. DESPITE MODERATE MID LEVEL RIDGING ALOFT...APPRECIABLE LOW LEVEL MOISTURE AND SURFACE HEATING...IN ADDITION TO SEVERAL WEAK SFC BOUNDARIES HAVE ALLOWED FOR STORM DEVELOPMENT. THIS WILL CONTINUE INTO THIS EVENING BEFORE DISSIPATING BY 9 PM. EXPECT THE STRONGER STORMS TO CONTAIN GUSTY WINDS OF 40 TO 50 MPH...BUT SEVERE STORMS WILL BE UNLIKELY. SHOULD A SEVERE WIND GUST OCCUR...IT WOULD BE MOST LIKELY OVER SOUTHWEST OKLAHOMA AND WESTERN NORTH TEXAS...WHERE LARGER TEMP-DEWPOINT SPREADS ARE APPARENT FROM RECENT MESONET OBS. HEIGHTS WILL GRADUALLY RISE OVERNIGHT INTO TOMORROW AS THE MID LEVEL RIDGE MOVES EAST INTO THE CENTRAL PLAINS. THIS SHOULD PREVENT MUCH IN THE WAY OF SHOWER/STORM ACTIVITY...AND AMPLE SUNSHINE SHOULD ALLOW FOR MORE WIDESPREAD TRIPLE DIGIT TEMPS THAN TODAY. ALTHOUGH HOT TEMPERATURES REMAIN IN THE FORECAST THROUGH THE WEEKEND...HEAT INDICES LOOK TO REMAIN MARGINAL FOR HEAT ADVISORY CRITERIA. THUS...HAVE OPTED TO DROP THE HEAT ADVISORY THAT WAS IN EFFECT FOR NORTHERN/CENTRAL AND SOUTHERN OKLAHOMA THROUGH FRIDAY NIGHT. STILL...PERSONS ARE ENCOURAGED TO FOLLOW HEAT SAFETY GUIDELINES AS VERY HOT CONDITIONS ARE EXPECTED TO CONTINUE. WILL KEEP THE FORECAST DRY FROM TOMORROW THROUGH SUNDAY AFTERNOON. BY THAT TIME...MODELS ARE IN GENERAL AGREEMENT IN SHOWING A RETROGRADING UPPER LOW. THIS LOW WILL ORIGINATE IN THE NORTHEAST...AND MOVE RELATIVELY QUICKLY WESTWARD INTO THE SOUTHEAST...AND EVENTUALLY SOUTHERN PLAINS BY MID WEEK. THIS WILL ALLOW FOR FALLING HEIGHTS FOR THE EARLY TO MIDDLE PART OF THE COMING WEEK...AND RESULT IN INCREASED RAIN CHANCES OVER MOST OF THE AREA. FOR NOW...WILL INTRODUCE SLIGHT CHANCE POPS BEGINNING SUNDAY AND LASTING THROUGH AT LEAST TUESDAY. CONFIDENCE IS STILL RELATIVELY LOW REGARDING THIS SCENARIO...AS WESTWARD PROPAGATING UPPER LOWS OF THIS MAGNITUDE ARE FAIRLY UNCOMMON. STILL...WITH ADEQUATE MOISTURE AND BROAD BUT PRESENT UPPER FORCING...EXPECTATIONS ARE THAT SOME BENEFICIAL RAIN WILL ARRIVE BY NEXT WEEK. THIS FEATURE WILL ALSO PUT A DING IN AFTERNOON HIGHS...WHICH SHOULD FALL FROM NEAR 100 OVER THE WEEKEND...TO NEAR 90 FOR THE FIRST HALF OF NEXT WEEK. BEYOND TUESDAY...LONG RANGE GUIDANCE BECOMES VERY UNCLEAR WITH RESPECT TO THE WESTWARD MOVING LOW. THUS...WILL REMOVE POPS FROM WEDNESDAY ONWARD AND KEEP TEMPERATURES NEAR CLIMO FOR MID JULY. && .PRELIMINARY POINT TEMPS/POPS...
