The episode as NWS OUN wrote it up.
A moist, tropical air mass was in place across Oklahoma, with several days of moderate to heavy rainfall over many areas. In additional to the influx of rich, Gulf moisture, the remnants of tropical storm Alex moved over the western half of Oklahoma. Some increase in low-level wind shear moved with the precipitation, with a weak tornado developing near I-40 in Caddo county. No damage was reported with the tornado, with it dissipating shortly after developing.
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 3, 1:34 PM CST, 3 hours 11 minutes earlier.
AREA FORECAST DISCUSSION...CORRECTED NATIONAL WEATHER SERVICE NORMAN OK 234 PM CDT SAT JUL 3 2010 .DISCUSSION... THE AIRMASS ACROSS THE REGION REMAINS VERY MOIST THROUGH A DEEP LAYER OF THE ATMOSPHERE WITH PRECIPITABLE H20 WELL ABOVE AVERAGE AS IT WAS COMPUTED TO BE NEAR 2.4 INCHES IN THIS MORNING'S 12Z OUN SOUNDING. WITHOUT THE PRESENCE OF A LOW-LEVEL BOUNDARY TO FOCUS PRECIPITATION... RAINFALL AMOUNTS THUS FAR HAVE BEEN GENERALLY MODERATE AS THE PRECIPITATION HAS BEEN MOVING ALONG... ALTHOUGH THERE HAVE BEEN SOME POCKETS OF HEAVY RAIN. FOR TONIGHT... THE MODELS SHOW A GENERAL AGREEMENT WITH MOVING A QPF MAXIMA ACROSS PARTS OF WESTERN OK AND FAR WESTERN NORTH TX. THIS FEATURE MAY BE PART OF THE REMNANT OF ALEX. WHILE SHOWERS WILL CONTINUE TO BE A GOOD BET OVER MOST OF THE CWA OVERNIGHT... WE WILL PLAY THE HIGHEST POPS AND QPF ACROSS THE WEST. IN SPITE OF A LACK OF A REASONABLY WELL-DEFINED BOUNDARY ACROSS THE AREA TONIGHT... SOME LOCALLY HEAVY RAINFALL AMOUNTS COULD OCCUR IN ASSOCIATION WITH THE SYSTEM MOVING ACROSS THE WESTERN PART OF THE CWA. MOST OF THIS AREA HOWEVER... MISSED OUT ON THE HEAVIER RAINS THAT OCCURRED LAST NIGHT AND TODAY IN PARTS OF WEST TX AND CENTRAL OK. THAT SAID... WE WILL CONTINUE TO MONITOR FOR THE DEVELOPMENT OF A MECHANISM THAT COULD RESULT IN EITHER STATIONARY RAIN AREAS... OR FOCUSES REDEVELOPMENT IN THE SAME AREA... WHICH COULD LEAD TO EXCESSIVE RAIN TOTALS GIVEN THE EXCEPTIONALLY HIGH WATER CONTENT IN THE AIR. RAIN CHANCES WILL CONTINUE TO BE RELATIVELY HIGH ON MONDAY DUE TO ONGOING MORNING ACTIVITY. ADDITIONAL DEVELOPMENT IS ALSO POSSIBLE LATER IN THE DAY AS THE SOUTHERN PART OF AN UPPER WAVE MOVING THROUGH THE CENTRAL PLAINS BRUSHES THE AREA. THE GFS DOES DEVELOP A SURFACE LOW OVER SOUTHWEST OK MONDAY NIGHT WHICH COULD ENHANCE LOW LEVEL CONVERGENCE IN THE AREA... HOWEVER... THIS APPEARS TO BE A CONVECTIVELY-INDUCED FEATURE CONFINED TO THE GFS... WHICH RESULTS IN A LOWER CONFIDENCE IN THIS SOLUTION. IN THE LONGER TERM... THE CONTINUED PRESENCE OF DEEP MOISTURE... ALONG WITH WEAK WAVES MOVING THROUGH THE AREA... WILL MAINTAIN THE CHANCE FOR SHOWERS INTO MUCH OF THE UPCOMING WEEK. THE GFS ALSO INDICATES THE POSSIBILITY FOR ADDITIONAL LOW-LEVEL FORCING TOWARDS THE END OF THE WEEK AS A WEAK COLD FRONT IS FORECAST TO DRIFT SOUTH INTO THE AREA. CLOUD COVER... HIGH HUMIDITIES AND SCATTERED PRECIPITATION WILL RESULT IN A RATHER NARROW RANGE IN TEMPERATURES INTO MONDAY... WITH A GRADUAL WARM-UP TO NEAR NORMAL VALUES BY THE MIDDLE OF THE WEEK. && .PRELIMINARY POINT TEMPS/POPS...
