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 Quad Cities, IA wrote its last area forecast discussion before the first event at Jul 8, 5:32 PM CST, 2 hours 28 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE QUAD CITIES IA IL 632 PM CDT MON JUL 8 2013 .SYNOPSIS... ISSUED AT 330 PM CDT MON JUL 8 2013 UPPER LEVEL WAVE IS SEEN MOVING INTO SOUTHWEST IA THIS AFTERNOON... WITH FRONTAL BOUNDARY ROUGHLY ALONG HIGHWAY 30 ACROSS IA. AN APPARENT SURFACE BASED STORM IS SEEN IN WEST CENTRAL IA ON NORTHERN FRINGE OF WAVE AND FRONTAL BOUNDARY INTERSECTION. ACROSS THE DVN CWFA CU FIELD IS SEEN ACROSS NORTHERN THIRD WITH CONVECTIVE DEBRIS CLOUDINESS ACROSS SOUTHWESTERN THIRD/HALF. WIDELY SCATTERED LIGHT RAIN SHOWERS CONTINUE TO MOVE SOUTHEASTWARD ACROSS SOUTHERN HALF OF CWFA. TEMPERATURES ARE IN THE MIDDLE 80S TO 90 DEGREES. && .SHORT TERM...(THIS EVENING THROUGH TUESDAY) ISSUED AT 330 PM CDT MON JUL 8 2013 ALTHOUGH TIMING AND PLACEMENT DETAILS AREA STILL UNCERTAIN...MODELS ARE INDICATING THAT SOME NOCTURNAL CONVECTION WILL DEVELOP ACROSS NE/SD WITH A SW TROUGH AND MOVE EASTWARD ACROSS IA DURING THE NIGHT AND THEN EAST SOUTHEAST AS IT APPROACHES EASTERN IA TOWARD DAYBREAK. CURRENT TIMING OF STORMS INTO THE DVN CWFA WOULD NOT BE INDICATIVE OF WIDESPREAD SEVERE WEATHER. MAIN THREATS WOULD BE WITH WIND DAMAGE AND HEAVY RAINS AND FLOODING FROM REPEATED STORMS. THIS EVENING WILL BE RATHER QUIET WITH CONTINUED WARM AND HUMID CONDITIONS AND A SLIGHT CHANCE FOR SOME SHOWERS. MORE WIDESPREAD CONVECTION WILL BE FOUND OVERNIGHT AND THROUGH THE DAY TUESDAY...AS THE SHORT WAVE MOVES ACROSS THE IA/MN BORDER. SLIGHT CHANCES THOUGH ABOUT MIDNIGHT...WITH HIGHEST LIKELY POPS ALONG AND NORTH OF I80 TOWARD DAYBREAK. LOCALLY HEAVY RAINFALL WILL BE A CONTINUING THREAT GIVEN PWATS HAVE BEEN ON THE INCREASE...WITH THE 12Z DVN SOUNDING INDICATING 1.86 INCHES. NEEDLESS TO SAY MUGGY LOWS TONIGHT MAINLY IN THE LOWER TO MIDDLE 70S...WITH HIGHS TUESDAY IN THE MID 80S TO LOW 90S. IF SUN BREAKS OUT DURING THE MID AM TO EARLY PM TIME FRAME... POSSIBLE MORE ROBUST STORMS WILL BE POSSIBLE FOR THE MID TO LATE AFTERNOON. .LONG TERM...(TUESDAY NIGHT THROUGH MONDAY) ISSUED AT 330 PM CDT MON JUL 8 2013 THE KEY TO THE WEEKEND AND EARLY NEXT WEEK WILL BE WHERE DOES THE NEW CUT OFF LOW DEVELOP OVER THE EASTERN CONUS AND WHERE DOES IT RETROGRADE TO. IF THE CUT OFF LOW PLACES ITSELF IN THE TENNESSEE OR DEEP SOUTH THEN THE AREA WOULD REMAIN VERY WARM AND DRY. IF THE CUT OFF LOW IS ALONG THE GULF COAST THEN THE AREA WOULD BE ON THE NORTHERN EDGE OF THE RING OF FIRE. WHAT OCCURS DURING THE DAY TUESDAY WILL DICTATE WHAT OCCURS TUES NIGHT/WED. THE MODELS AGREE THAT A RESPECTABLE SHORTWAVE AND FRONT WILL SWEEP THROUGH THE AREA LATE TUES NIGHT/WED MORNING. CONVECTION THAT DEVELOPS TUES AFTERNOON SHOULD REMAIN SCATTERED INTO THE EVENING PRIOR TO THE FRONT. ALTHOUGH THE FORCING IS NOT GREAT... THE CONVECTION MAY EVOLVE INTO A LOOSELY ORGANIZED MCS ALONG THE FRONT. DOWNWARD MOTION IMPLIED BY THE MODELS BEHIND THE FRONT SHOULD THEN END THE RAIN THREAT A FEW HOURS AFTER FRONTAL PASSAGE. THUS RAIN WILL END FROM ROUGHLY NORTHWEST TO SOUTHEAST FROM LATE TUES NIGHT THROUGH EARLY WED AFTERNOON. LATE WED AFTERNOON LOOKS TO BE DRY ACROSS THE ENTIRE AREA. QUIET AND DRY CONDITIONS WILL BE SEEN ACROSS THE AREA WED NIGHT AND THURSDAY AS THE NEXT CANADIAN HIGH PRESSURE BUILDS INTO THE MIDWEST. THURSDAY NIGHT ON... THE MODEL CONSENSUS HAS DRY CONDITIONS FOR THURS NIGHT THROUGH FRIDAY NIGHT AS DRY AIR REMAINS ACROSS THE AREA AS THE CANADIAN HIGH MOVES INTO THE GREAT LAKES. INTERNALLY...THE MODELS ARE SUGGESTING A RESPECTABLE MCS DEVELOPING IN THE PLAINS FRIDAY EVENING THAT SHOULD BE JUST WEST OF THE CWFA AT SUNRISE SATURDAY MORNING. IF THE MCS DEVELOPS AS SUGGESTED FRIDAY NIGHT...THEN THE REMNANTS OF IT WILL SPREAD INTO THE WESTERN CWFA ON SATURDAY BEFORE DISSIPATING. THE MODELS ARE VARIED ON THEIR RESPECTIVE SOLUTIONS AND CURRENTLY ONLY GIVE SCHC POPS ON SATURDAY. THE MODELS SUGGEST ANOTHER MCS DEVELOPING SATURDAY NIGHT BUT NOT ARRIVING INTO THE WESTERN CWFA UNTIL AROUND DAWN AND THEN SLOWLY DISSIPATING ACROSS THE CWFA ON SUNDAY. THIS PATTERN IS SUGGESTED AS REPEATING AGAIN SUNDAY NIGHT INTO MONDAY AS THE RING OF FIRE BECOMES ESTABLISHED. AS SUCH...THE MODEL CONSENSUS YIELDS MAINLY SCHC POPS FOR THE SATURDAY NIGHT THROUGH MONDAY TIME FRAME. ..08.. && .AVIATION...(FOR THE 00Z TAFS THROUGH 00Z TUESDAY EVENING) ISSUED AT 631 PM CDT MON JUL 8 2013 A SERIES OF UPPER LEVEL DISTURBANCES WILL KEEP THUNDERSTORM CHANCES OVER THE REGION TONIGHT THROUGH TUESDAY NIGHT. THIS EVENING...ISOLATED ACTIVITY IS EXPECTED TO BE AT LEAST IN THE VICINITY OF THE BRL AND DBQ TERMINALS...WITH MAINLY VFR CONDITIONS ELSEWHERE. MORE ORGANIZED SHOWERS AND THUNDERSTORMS WILL LIKELY MOVE THROUGH THE AREA WELL AFTER MIDNIGHT...WHEN PROB30 GROUPS ARE UTILIZED...TRANSITIONING TO TEMPO OR CATEGORICAL MENTION AROUND SUNRISE. THERE WILL LIKELY BE A LULL BETWEEN SYSTEMS FROM LATE MORNING THROUGH MUCH OF TUESDAY AFTERNOON...BUT ANOTHER ROUND OF THUNDERSTORMS IS LIKELY WITH AN APPROACHING COLD FRONT TUESDAY NIGHT...JUT BEYOND THE FORECAST PERIOD. && .DVN WATCHES/WARNINGS/ADVISORIES...

LIGHTNING AND LOCALLY HEAVY RAINFALL WILL BE THE MAIN HAZARDS WITH THESE STORMS. HEAT INDEX READINGS MAY APPROACH THE UPPER 90S TO 100 DEGREES THIS AFTERNOON. LATER THIS AFTERNOON AND TONIGHT...ADDITIONAL THUNDERSTORMS ARE EXPECTED TO DEVELOP OVER THE OUTLOOK AREA. AN ISOLATED SEVERE STORM WITH DAMAGING WINDS WILL BE POSSIBLE. HOWEVER...THERE IS SOME POTENTIAL FOR A COMPLEX OF STORMS WITH A MORE WIDESPREAD WIND DAMAGE THREAT TO DEVELOP OVER THE DAKOTAS. SHOULD THIS OCCUR THEN THESE STORMS WOULD LIKELY MOVE INTO THE OUTLOOK AREA LATER TONIGHT...ESPECIALLY NORTH OF INTERSTATE 80 AND CONTAIN A MORE WIDESPREAD DAMAGING WIND THREAT. IN ADDITION...ANY THUNDERSTORMS WILL ALSO PRODUCE LOCALLY HEAVY RAINFALL. .DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY MORE ROUNDS OF THUNDERSTORMS ARE EXPECTED TUESDAY AND TUESDAY NIGHT. CURRENT INDICATIONS SUGGEST THUNDERSTORMS ARE MORE LIKELY NORTH OF INTERSTATE 80 TUESDAY MORNING THROUGH MIDDAY. HEAVY RAIN AND ISOLATED SEVERE STORMS WOULD BE POSSIBLE WITH THIS ACTIVITY. THEN THE ENTIRE OUTLOOK AREA WOULD BE AT RISK OF STRONG TO SEVERE THUNDERSTORMS LATE TUESDAY AFTERNOON AND NIGHT. DAMAGING WIND GUSTS ARE THE PRIMARY SEVERE WEATHER THREAT WITH THESE LATE DAY STORMS. LOCALLY HEAVY RAIN WILL ALSO CONTINUE TO BE PROBABLE WITH ANY STORM COMPLEX TUESDAY NIGHT ALONG WITH THE CHANCE FOR SOME URBAN AND SMALL STREAM FLOODING. THE STORM PREDICTION CENTER HAS PLACED THE ENTIRE OUTLOOK AREA IN SLIGHT RISK FOR SEVERE WEATHER TUESDAY. HEAT INDEX READINGS MAY APPROACH THE UPPER 90S TO 100 DEGREES IN SOME AREAS ALONG AND SOUTH OF INTERSTATE 80 TUESDAY AFTERNOON. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION MAY BE NEEDED FOR PORTIONS OF THE OUTLOOK AREA TONIGHT AND AGAIN ON TUESDAY.
