What happened
The episode as NWS OTX wrote it up.
A thunderstorm containing brief heavy rain went through Lewiston resulting in urban flooding. During the height of the storm, water was four to five inches deep flowing down Lewiston Orchards streets. On Bryden Avenue, water flowed out of manhole covers and sent two by four's and garbage cans floating down the street. Standing water was observed to the height of sidewalks for a few hours after the rain. From 1:43 PM PST through 1:54 PST, the ASOS at the airport in Lewiston picked up 0.54 inches of rain.

Area forecast discussion, Jun 9, 1:27 PM PST, 8 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPOKANE WA 227 PM PDT WED JUN 9 2010 .SYNOPSIS... A CLOSED UPPER LEVEL LOW WILL MOVE INTO THE REGION TONIGHT AND REMAIN OVER THE AREA THROUGH FRIDAY. SHOWERS...THUNDERSTORMS AND COOLER TEMPERATURES CAN BE EXPECTED THE REST OF THE WORK WEEK. HIGH PRESSURE BEGINS TO NOSE INTO THE AREA LATE FRIDAY...THEN STRENGTHENS THROUGH THE WEEKEND. TEMPERATURES WILL WARM ABOVE SEASONAL NORMS. WARM AND DRY CONDITIONS WILL ONCE AGAIN BE FOLLOWED BY A WEATHER SYSTEM TUESDAY FOR COOLER TEMPERATURES AND MOUNTAIN SHOWERS. && .DISCUSSION... TONIGHT...ONLY MINOR CHANGES WERE MADE TO THE FORECAST FOR THIS EVENING. THE UPPER LEVEL LOW IS SLOWLY TRACKING INTO THE REGION MUCH AS THE MODELS HAD FORECAST. THE STRATIFORM PRECIPITATION FROM THIS MORNING HAS TURNED CONVECTIVE AS THE ATMOSPHERE HAS DESTABILIZED BEHIND THE ASSOCIATED COLD FRONT. CLEARING SKIES IN COMBINATION WITH THE APPROACHING COLD CORE HAS RESULTED IN SURFACED BASED CAPE VALUES BETWEEN 500-1000J/KG...WITH LAPSE RATES EXPECTED TO BE BETWEEN 7-9 C/KM . SCATTERED SHOWERS HAVE BEEN ONGOING SINCE 18Z AND THUNDERSTORMS WILL HAVE NO PROBLEM DEVELOPING THROUGH THE REMAINDER OF THE AFTERNOON. 0-6KM SHEAR VALUES ACROSS MY SOUTHEAST ZONES FROM THE BLUE MOUNTAINS NORTHEAST TO SOUTHERN SHOSHONE COUNTY RANGE FROM 40-50KT FROM LATE THIS AFTERNOON AND EARLY EVENING AND THIS WOULD BE THE AREA THAT HAS THE BEST POTENTIAL FOR SEVERE THUNDERSTORMS THROUGH SUNSET. THE FOCUS FOR THIS EVENING AND OVERNIGHT WILL BE THE AFOREMENTIONED WAVE CLEARLY SEEN ON SATELLITE IMAGERY MOVING INTO THE AREA. THIS WILL PROVIDE THE LIFTING MECHANISM TO TAP INTO THE MID LEVEL INSTABILITY WELL AFTER SUNSET. WITH THAT IN MIND THE CHANCES FOR SHOWERS AND THUNDERSTORMS WERE KEPT HIGH EAST OF AN AREA FROM ABOUT OMAK TO PASCO...THEN SLOWLY DECREASING FROM THE WEST AFTER 06Z. /TOBIN THURSDAY THROUGH FRIDAY NIGHT...AN UPPER TROUGH WILL CONTINUE TO BRING COOL AND UNSETTLED WEATHER TO THE REGION...BEFORE A SHORT- WAVE RIDGE STARTS TO BUILD IN AT THE END OF THE PERIOD. ON THURSDAY MORNING THE MEAN TROUGH AXIS BISECTS THE PACIFIC NW...AND GRADUALLY SHIFTS TOWARD THE ROCKIES BY THURSDAY NIGHT AND FRIDAY. LOBES OF VORTICITY WILL BE EMBEDDED IN FLOW AROUND THE TROUGH. ONE WILL BE IN THE PROCESS OF PASSING THROUGH ERN WA/NRN ID EARLY THURSDAY. A SECOND SKIMS BY THE SOUTH/EAST CWA BY LATE MORNING TO AFTERNOON. THEN BY THURSDAY NIGHT INTO FRIDAY THE FLOW TURN NNW...WHICH BRINGS A COUPLE WEAKER VORTICITY STRAND BY THE NORTH TO EASTERN CWA. WITH SOME MOISTURE STILL WRAPPED-UP IN THE TROUGH AND AT LEAST LOW-GRADE CONVECTIVE INSTABILITY PRESENTING ITSELF DURING EACH AFTERNOON...THESE VORT LOBES WILL KEEP SHOWER CHANCES GOING. HOWEVER THE PRIMARY SHOWER CHANCES WILL SHIFT TOWARD THE EASTERN/SOUTHEAST CWA BY FRIDAY AS THE FLOW SHIFTS. WILL KEEP A SLIGHT CHANCE OF THUNDERSTORMS GOING ON THURSDAY AFTERNOON GIVEN THE DEPICTED CONVECTIVE INSTABILITY AND FORCING. HOWEVER WITH 0-6KM SHEAR WEAKENING WITH THE JET AXIS MOVING SOUTH THE STORMS THAT MAY DEVELOP ARE NOT PROJECTED TO BE ORGANIZED OR VERY STRONG. WHILE THERE IS SOME CONVECTIVE INSTABILITY FOR FRIDAY AFTERNOON...THE LACK OF STRONG FORCING OR SHEAR LEADS ME TO KEEP ANY MENTION OF THUNDER OUT. BY FRIDAY NIGHT SOME DRIER AIR STARTS TO MOVE IN...FURTHER PUSHING THE SHOWER THREAT INTO THE PANHANDLE MOUNTAINS WHERE THEY WANE INTO THE OVERNIGHT. /JCOTE SATURDAY THROUGH WEDNESDAY...EXTENDED MODELS ARE IN GOOD AGREEMENT THROUGH MONDAY...THEN BEGIN TO SHOW DIFFERENCES FOR TUE/WED. WARMER TEMPERATURES AND DRY CONDITIONS WILL OCCUR OVER THE WEEKEND AS AN UPPER RIDGE MOVES OVER THE AREA WITH HIGH TEMPERATURES WARMING TO ABOVE NORMAL READINGS WITH SUNDAY THE WARMEST DAY. THE RIDGE THEN FLATTENS ON MONDAY IN RESPONSE TO AN UPPER TROUGH DROPPING SOUTH FROM CANADA. THE GFS MODEL THEN TRACKS THE UPPER TROUGH ACROSS SOUTHERN BC ON TUESDAY WHICH SENDS A DRY COLD FRONT ACROSS THE AREA...FOLLOWED BY DRY WESTERLY FLOW ON WEDNESDAY. THE LATEST 12Z ECMWF AND CANADIAN MODELS DIG THE TROUGH MORE AGGRESSIVELY OVER THE PACIFIC NW WITH THE ECMWF SHOWING A CLOSED LOW OVER WASHINGTON ON TUESDAY MOVING INTO MONTANA ON WEDNESDAY. THIS WOULD GIVE AT LEAST THE MTNS A GOOD CHANCE FOR SHOWERS. GIVEN THAT PREVIOUS ECMWF SUPPORTED THE GFS OPTED TO MAKE VERY FEW CHANGES TO THE FCST WHICH FAVORS THE DRIER GFS. HOWEVER THIS PART OF THE FORECAST MAY CHANGE IF THE GFS TRENDS TO THE ECMWF/CANADIAN. REGARDLESS OF THE DETAILS OF THE TROUGH PASSAGE...CONFIDENCE IS HIGH OF TEMPERATURES COOLING TO AT LEAST SLIGHTLY BELOW NORMAL TUE/WED. JW && .AVIATION... ALL LOCATIONS WILL BE SUBJECT TO SCATTERED SHOWERS AND EMBEDDED THUNDERSTORMS THROUGH SUNSET...WITH THE FOCUS SHIFTING TO EAST OF SPOKANE AFTER SUNSET. THE AREA OF MOST CONCERN WILL LIKELY OCCUR OVER SOUTHEAST WASHINGTON AND NORTH CENTRAL IDAHO WHERE THE BEST SHEAR WILL BE AVAILABLE STRONGER CONVECTION AND THIS WILL IMPACT KLWS. ALL THUNDERSTORMS WILL HAVE THE POTENTIAL TO CONTAIN GUSTY WINDS AND SMALL HAIL. THUNDER CHANCES WILL DECREASE BY MIDNIGHT...BUT EXPECT SHOWERS TO REMAIN ACTIVE THROUGH THE NIGHT. /TOBIN && .PRELIMINARY POINT TEMPS/POPS...
