Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

Area forecast discussion, Jul 11, 6:28 AM EDT, 8 hours 35 minutes before
AREA FORECAST DISCUSSION..FINAL LT MID SHIFT.. NATIONAL WEATHER SERVICE TAUNTON MA 628 AM EDT TUE JUL 11 2006 ...POTENTIAL EXISTS FOR ISOLATED TO SCATTERED SEVERE THUNDERSTORMS TODAY AND THE POSSIBILITY FOR HEAVY RAIN/SEVERE WEATHER WEDNESDAY AFTERNOON AND NIGHT AND THEN A 3 TO 5 DAY HEAT WAVE SEEMS TO BE DEVELOPING FOR PARTS OF THE CONNECTICUT RIVER VALLEY CENTERED ON THIS WEEKEND... .SHORT TERM /TODAY THROUGH WEDNESDAY/... ONE COMPLEX OF SHOWERS AND THUNDERSTORMS ALREADY IN CENTRAL NEW YORK STATE WILL BE KNOCKING ON THE DOOR OF OUR WESTERN ZONES BETWEEN 5 AND 7 AM. THE BRUNT OF THIS ACTIVITY LOOKS TO AFFECT NORTHWEST MA AND SOUTHWEST NH WHERE WE WILL GO WITH CATEGORICAL POPS. HOWEVER...THE FRONT IS STILL TO THE WEST OF BUFFALO AND THE GFS SHOWS PLENTY OF 700 MB OMEGA/RELATIVE HUMIDITY EVEN AT 18Z. THEREFORE...WE EXPECT OTHER SHOWERS AND THUNDERSTORMS TO REFIRE. WILL CARRY LIKELY POPS FOR THE REST OF THE REGION NORTHWEST OF I-95 QUICKLY TRIMMING THEM TO SLIGHT CHANCES ON THE CAPE AND ISLANDS BECAUSE OF THE MARINE INFLUENCE. DESPITE A LOT OF CLOUD DEBRIS FROM THE INITIAL COMPLEX...WE SHOULD SEE SOME SUN AT TIMES OVER PORTIONS OF THE AREA ALLOWING FOR THE ATMOSPHERE TO DESTABILIZE. DEWPOINTS CLIMBING INTO THE MID TO UPPER 60S WILL RESULT IN CAPE VALUES OF AROUND 1500 J/KG WITH EXPECTED HIGHS IN THE 80S. WIND FIELDS ARE BETWEEN 30 AND 40 KNOTS FROM JUST OFF THE DECK THROUGH 500 MB. WITH ALL THAT SAID THERE IS THE POTENTIAL FOR SOME ISOLATED TO SCATTERED SEVERE THUNDERSTORMS...WITH THE MAIN THREATS BEING LARGE HAIL AND DAMAGING STRAIGHT LINE WINDS. WILL INSERT ENHANCED WORDING INTO THE ZONES AND ISSUE A SPECIAL WEATHER STATEMENT. SEVERE WEATHER POTENTIAL TODAY WILL DEPEND UPON IF WE CAN GET ENOUGH HEATING. MID LEVELS RAPIDLY DRY OUT THIS EVENING AND EXPECTING A RATHER QUIET NIGHT. COULD SEE AN ISOLATED SHOWER OR THUNDERSTORM POP WITH THE LOW LEVEL JET BUT EVEN IF THIS OCCURS AREAL COVERAGE SHOULD BE VERY LIMITED. WILL JUST GO WITH 15 TO 20 POPS. ALSO EXPECT LOW CLOUDS TO FORM ACROSS PORTIONS OF THE REGION AS LOW LEVEL MOISTURE INCREASES. ON WEDNESDAY...NUMEROUS SHOWERS AND THUNDERSTORMS WILL BE ON GOING EARLY IN THE MORNING ACROSS PORTIONS OF NEW YORK AND PENNSYLVANIA. THIS ACTIVITY SHOULD SLIDE INTO OUR WESTERN ZONES WEDNESDAY AFTERNOON. THE ATMOSPHERE WILL BE REALLY JUICED WITH DEWPOINTS POSSIBLY EXCEEDING 70. THERE IS SOME DISAGREEMENT ON THE WIND DIRECTIONS/SPEEDS BECAUSE OF THE CONVECTION. IF AND HOW MUCH SUN DEVELOPS ON WEDNESDAY IS UNCERTAIN BECAUSE OF TIMING ISSUES. IF WE ARE ABLE TO DESTABILIZE THERE IS THE POTENTIAL FOR SEVERE WEATHER WITH THE MAIN THREAT BEING WET MICROBURSTS. JUST GOT A LOOK AT THE 00Z ECMWF/6Z NAM WIND FIELDS AND THEY ARE IMPRESSIVE. THEY SUGGEST THE POTENTIAL FOR A FEW SUPERCELL THUNDERSTORM IF WE CAN GET ENOUGH SUN AND INSTABILITY. THIS REMAINS UNCERTAIN BUT DEFINITELY SOMETHING TO WATCH. IN ADDITION...THE POTENTIAL FOR THESE THUNDERSTORMS TO PRODUCE TORRENTIAL RAINFALL AND POSSIBLY SOME URBAN TYPE FLASH FLOODING. THERE IS STILL SOME UNCERTAINTY THOUGH WITH THE TIMING AND WE BELIEVE THE GFS IS A BIT FAST. THEREFORE...KEPT THE COAST JUST IN CHANCE POPS THROUGH 00Z AS THE GFS LOOKS A BIT FAST. && .LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/... PATTERN...HUGE 500 MB RIDGE DEVELOPS ACROSS THE E 2/3RDS OF THE USA INTO S CANADA...POSSIBLY RELATED TO A HUGE PLUNGE IN THE PNA FROM FROM ITS CURRENT +2 SD TO NEUTRAL BY SATURDAY AND THEN POSSIBLY STEPPING DOWN INTO NEG TERRITORY SHORTLY THERE AFTER. THAT SPREADS HEAT EMANATING IN MONTANA EWD ACROSS S CANADA AND THEN SEWD INTO SNE. THIS HAS +2SD 850 TEMPS MODELED ACROSS S E CANADA AND +1SD INTO AREA OVER THE WEEKEND ESP SUN-MONDAY. BACKDOORING IS NOT IN THE CARDS THIS WEEKEND. INSTEAD...THE PROMINENCE OF HEAT MAY BE DELAYED A DAY OR SO DUE TO THE STRENGTH OF THE RIDGING OCCURRING NORTH OF OUR AREA. HEAT WAVE POTENTIAL...A 3 TO 5 DAY HEAT WAVE IS POSSIBLE FOR THE CT RIVER VALLEY BEGINNING FRIDAY OR SATURDAY. 06Z GFS IS BACK ON LINE FOR RAPID WARMING FRIDAY AND 90 MAY STILL BEGIN AT BDL-CEF-BAF REGION FRI AFTN. 97F IS POSSIBLE IN THIS PATTERN WITH FULL SS AND WLY SFC WIND CT RIVER VALLEY. TEMPS: CONTINUES WARMER THAN NORMAL THROUGH AT LEAST TUESDAY OF NEXT WEEK. THAT SAID...THIS LOW PASSING THROUGH NEW ENGLAND WED NIGHT MAY LEAVE ENOUGH COOL MARITIME AIR BEHIND TO ALLOW THURSDAY TO BE AT OR JUST BELOW NORMAL. PCPN: AFTER THE LATE WED-THU PROBABLE HEAVY RAIN EVENT AS SEEN IN THE 00Z/11 UKMET OP RUN AND 00Z/11 GFS ENS /MULTIPLE CONSECUTIVE GFS ENS CYCLES OF HEAVY RAIN HERE IN SNE SINCE DEPARTING FROM ITS DRY 18Z/8 WEDNESDAY ENS RUN...WE COULD BE RAINFREE FROM THU NIGHT THRU AT LEAST NEXT MONDAY THE 17TH. THE DAILIES... WEDNESDAY NIGHT...GFS/UKMET/ECMWF MERGED WITH A HEAVY RAIN VENT PROBABLE. HPC QPF WAS USED AS THE BASIS FOR THE FCST GENERATING HEAVY SHOWERS. TEMPS WERE 00Z/11 GFS MAV MOS...AND CLOSE TO THE PREV FCST. CONFIDENCE ABOVE AVG ON HEAVY RAIN...THOUGH THE PRIMARY AXIS MAY BE A BIT FURTHER NORTH THAN MODELED IN THE GFS ENS. HOWEVER FOR NOW...THE AXIS OF MAX RAINFALL IS PREDICTED TO BE IN MASSACHUSETTS. CONFIDENCE BELOW AVG ON WIND DIRECTION AND TIMING OF THE WIND SHIFTS PER TRACK OF THE SFC LOW SOMEWHERE THROUGH S OR CENTRAL NEW ENGLAND. +00Z/10 GFS ENS HAS +3SD PWAT FOR CT RI/MA. DAILY RFALL RECORDS FOR WEDNESDAY AND THURSDAY ARE GENERALLY ABOVE 2.5 INCHES AND WILL NOT BE LISTED. BOSTONS 1.00 ON 7/12/1975 IS POSSIBLY VULNERABLE TO BE EXCEEDED...AND TO A LESSER DEGREE THE PVD 1.72 INCHES SET ON 7/12/1918. ESF WILL BE ISSUED AROUND 645 AM. THURSDAY...TROF ALOFT WORKING ON LEFTOVER MOISTURE COMBINED WITH CONVERGENCE NEAR THE SFC COOL FRONT SHOULD GENERATED SMALL AMOUNTS OF NUISANCE RAIN. POPS FOR NOW RAISED TO 50 PCT MASS PIKE SWD. SMALL CHANCE OF A TSTM S OF THE COOL FRONT WHERE EVER IT IS...IF A BIT OF SUN. THURSDAY NIGHT...DRIES OUT. FOG IN THE CT RIVER VALLEY POSSIBLE DUE TO LEFTOVER BL RH AND LIGHT WIND. FRIDAY...WARMS RAPIDLY WITH DRY AIR MIXING DOWN FROM ALOFT. 850 MB TEMPS TEMPORARILY COOLED FM THE NLY FLOW IN THE WAKE OF THE DEPARTING LOW COMBINED WITH WET GROUND MAY NOT ALLOW FOR 90F IN THE CT RIVER VALLEY FRI...BUT THE 06Z GFS IS COMING BACK TO THE HEAT SOLN. DETAILS YET TO BE DTERMINED. STILL QUITE A NICE DAY IS ANTICIPATED. SATURDAY-SUNDAY...WARMING DAILY ON LIGHT WLY BL FLOW WITH SEABREEZES ON PARTS OF THE COASTAL PLAIN...DETAILS STILL TO BE DETERMINED. SHOULD BE 90 TO 95F /06Z GFS OFFERS 95F POTENTIAL/ INTERIOR...AND ACTUALLY A VERY FINE WEEKEND..IF YOU LIKE IT HOT MONDAY...CURRENTLY ANTICIPATED TO BE THE HOTTEST DAY OF THIS WARM SPELL. 18C 850 TEMPS AND W OR SW BL FLOW. TUESDAY...COULD BE WET...VERY WARM AND HUMID. && .AVIATION... LOW CLOUDS WERE DEVELOPING ALONG THE SOUTH COAST...CAPE AND ISLANDS EARLY THIS MORNING. THESE SHOULD MIX OUT WITHIN A FEW HOURS OF SUNRISE. OTHERWISE...VFR CONDITIONS WILL BE MIXED WITH IFR/LIFR IN SCATTERED THUNDERSTORMS. CONDITIONS SHOULD RETURN TO VFR FOR A TIME TONIGHT BUT LOW CLOUDS LOOK TO COME BACK WITH MORE DEEP LOW LEVEL MOISTURE ARRIVING LATE. && .MARINE... GENERALLY EXPECTING 3 TO 4 FOOT SEAS WITH WIND GUSTS TO 20 KT TODAY THOUGH WEDNESDAY. HAVE UNDERCUT WNA MODEL A BIT WITH ITS CONTINUED BIAS OF TOO MUCH MIXING OVER THE COOL OCEAN. WEDNESDAY NIGHT AND THURSDAY...SCA SEAS POSSIBLE DUE TO SW FLOW FETCH S COAST AND A POSSIBLE BURST OF NE WINDS TO 30 KTS THU MORNING IN THE NE MASS WATERS. CONFIDENCE BELOW AVG DUE TO WIND DIRECTION AND WIND SPEED ISSUES. ECMWF AND UKMET NOT AS IMPRESSIVE AS THE GFS. GREAT WEATHER FOR THE MARINER ANTICIPATED FRIDAY AND THIS WEEKEND /BARRING A BAHAMAS DEVELOPMENT/ BUT WITH RATHER LIGHT VARIABLE WIND. && .HYDROLOGY... THE POTENTIAL FOR HEAVY RAIN AND POSSIBLY URBAN FLASH FLOODING EXISTS ACROSS THE INTERIOR WEDNESDAY AFTERNOON/EVENING.

SOUTHERN RHODE ISLAND AND RHODE ISLAND COASTAL WATERS. .DAY ONE...TODAY AND TONIGHT AN INITIAL BAND OF SHOWERS AND STRONG THUNDERSTORMS AT 6 AM WAS ALREADY ENTERING EXTREME WESTERN NEW ENGLAND. THIS ACTIVITY WILL MOVE INTO SOUTHERN NEW HAMPSHIRE AND MUCH OF WESTERN MASSACHUSETTS EARLY THIS MORNING. ALTHOUGH THESE THUNDERSTORMS ARE NOT SEVERE THEY CONTAIN DANGEROUS CLOUD TO GROUND LIGHTNING. AWAY FROM THIS INITIAL BAND OF THUNDERSTORMS...THERE WILL BE PARTIAL SUNSHINE TODAY. THIS SHOULD ALLOW TEMPERATURES TO CLIMB INTO THE 80S AND RESULT IN A MODERATELY UNSTABLE AIRMASS. ADDITIONAL THUNDERSTORMS ARE EXPECTED TO DEVELOP LATER THIS MORNING AND INTO THE AFTERNOON. SOME OF THESE STORMS COULD POTENTIALLY BECOME SEVERE...PRODUCING DAMAGING STRAIGHT LINE WIND GUSTS AND LARGE HAIL. IN ADDITION...ANY THUNDERSTORM THAT DEVELOPS WILL BE CAPABLE OF PRODUCING DANGEROUS CLOUD TO GROUND LIGHTNING AND LOCALLY HEAVY RAINFALL. .DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY NUMEROUS SHOWERS AND THUNDERSTORMS ARE EXPECTED TO DEVELOP OVER THE INTERIOR WEDNESDAY AFTERNOON AND REACH THE COAST BY EARLY EVENING. THERE IS POTENTIAL FOR SEVERE WEATHER IF WE CAN GET ENOUGH SUNSHINE. THE PRIMARY THREATS WILL BE DAMAGING STRAIGHT LINE WIND GUSTS AND POSSIBLY LARGE HAIL. THERE IS EVEN A CHANCE FOR A FEW SUPERCELL THUNDERSTORMS. SEVERE WEATHER POTENTIAL ON WEDNESDAY WILL DEPEND ON JUST HOW MUCH SUNSHINE WE GET AND WE WILL KNOW MORE LATER THIS AFTERNOON. IN ADDITION...ANY THUNDERSTORM THAT DEVELOPS ON WEDNESDAY WILL BE CAPABLE OF PRODUCING TORRENTIAL RAINFALL. THIS MAY RESULT IN SOME URBAN FLASH FLOODING. SHOWERS AND STRONG THUNDERSTORMS WILL CONTINUE INTO WEDNESDAY NIGHT. TOTAL RAINFALL FROM NOON WEDNESDAY TO DAYBREAK THURSDAY IS LIKELY TO AVERAGE 1 TO 2 INCHES IN SOUTHERN NEW ENGLAND WITH ISOLATED 4.5 INCH AMOUNTS. TRAVEL IS LIKELY TO BE IMPACTED IN PORTIONS OF SOUTHERN NEW ENGLAND BY THE HEAVY RAINS LATE WEDNESDAY. HEAT WAVE /3 CONSECUTIVE DAYS OF 90 DEGREES OR ABOVE/ TEMPERATURES OF 90 TO 95 DEGREES ARE ANTICIPATED FOR THE CONNECTICUT RIVER VALLEY THIS WEEKEND THROUGH MONDAY BUT THE HUMIDITY SHOULD NOT BE EXCESSIVE THIS WEEKEND. THERE IS STILL A CHANCE THAT THE 90 DEGREE HEAT WILL BEGIN AS EARLY FRIDAY AFTERNOON IN THE HARTFORD SPRINGFIELD AREA. THIS DEVELOPING PATTERN MAY ALLOW FOR HEAT ADVISORY CRITERIA SUNDAY OR MORE LIKELY MONDAY. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION WILL BE NEEDED LATE THIS MORNING INTO THE AFTERNOON FOR ISOLATED TO SCATTERED SEVERE THUNDERSTORMS.
