CLEAR SKY EXPECTED MOST OF THE DAY...WITH HIGH-BASED CUMULUS DEVELOPING AROUND KDHT AROUND 21Z WEDNESDAY. COCKRELL && .PREV DISCUSSION... /ISSUED 349 PM CDT TUE SEP 2 2014/ DISCUSSION...TONIGHT THROUGH NEXT TUESDAY NO OVERWHELMING CHANGES WERE MADE TO THE FORECAST AS UNCERTAINTY CONTINUES TO ABOUND LATER IN THE PERIOD. ONE OF THE MAIN SOURCES OF UNCERTAINTY CONTINUES TO BE THE TROPICS AS TS DOLLY IN THE WRN GULF AND TS NORBERT IN THE ERN PACIFIC WILL CERTAINLY CONTRIBUTE MOISTURE TO THE PATTERN EVENTUALLY. THESE SYSTEMS WILL ALSO AFFECT THE OVERALL UPR AIR PATTERN EVOLUTION IN WAYS THAT WILL NOT BE WELL MODELED. TONIGHT THROUGH THURSDAY... PRECIP CHANCES WILL BE MINIMAL DURING THIS PERIOD. AFTER THE LIGHT WINDS THIS AFTERNOON...WED AND THU WILL BE MUCH BREEZIER DAYS AS SSW WINDS PICK UP. THURSDAY NIGHT... INCREASED RAIN CHANCES IN THE WRN OK PANHANDLE THIS PERIOD AS MODELS HAVE COME INTO FAIR AGREEMENT WITH A COLD FRONT SLIPPING IN AND ERLY UPSLOPE FLOW DEVELOPING IN ADVANCE OF A WEAK SHRTWV. FRIDAY THROUGH MONDAY NIGHT... TRIED VERY HARD TO PIN DOWN A TIME PERIOD OR LOCATION WHERE PRECIP CHANCES WILL BE HIGHEST BUT WEAK FORCING IN THE PRESENCE OF DEEP MOISTURE MEANS CONVECTION WILL BE DIFFICULT TO FORECAST.
