What happened

The episode as NWS GJT wrote it up.

A father and his two sons were struck by lightning after seeking shelter from a thunderstorm under a tall cottonwood tree. The three men were on a golf course and had sought shelter under the tree when it started to rain. Lightning struck the tree and then passed through all three men, leaving each with severe burns. One victim also suffered a head injury as he was thrown to the ground.

NATIONAL WEATHER SERVICE GRAND JUNCTION CO
222 AM MDT MON AUG 6 2001

DEEP EASTERLY FLOW OVER THE FORECAST AREA THIS MORNING ENHANCING
DRAINAGE WINDS IN MOST VALLEYS LOCATIONS.  THIS IS HELPING TO KEEP
OVERNIGHT MINS RATHER WARM SO FAR.  SOME DECREASE IN SPEEDS WL OCCUR
NEAR SUNRISE...SO WE SHOULD STILL DROP DOWN TO NEAR FORECAST
VALUES.

BIG STORY OVER THE NEXT 48 HOURS WILL BE CONVECTIVE POTENTIAL AS
MOIST EASTERLY FLOW PERSISTS THROUGH THE PERIOD. PLENTY OF STORMS
FIRED LAST EVENING WITH SOME ACTIVITY STILL LINGERING OVER THE SAN
JUANS THIS MORNING.  CLOUDY START TO DAY WILL SLOW HEATING...BUT
PROXIMITY OF SHRTWV HEADING WEST OF THE DIVIDE WL HELP TO TRIGGER
ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS THIS AFTERNOON AND
TONIGHT.  EXPECT MORE ACTIVITY NORTH OF INTERSTATE 70 AS WELL WITH
MODELS INDICATING BETTER MOISTURE MOVING INTO THAT AREA.  IN
ADDITION...MID LEVEL TEMPS NOT EXPECTED TO WARM AS MUCH AS EARLIER
RUNS WERE INDICATING...SO WE SHOULD BE ABLE TO OVERCOME THE WEAK MID-
LEVEL CAP ACROSS THE NORTH.  UPSTREAM SOUNDINGS...AND WERE TALKING
KDDC/KAMA AND KBOU THIS MORNING...SHOWING PRECIPITABLE WATER VALUES
STILL IN EXCESS OF 1 INCH. THIS COMBINED WITH THE FACT THAT STORMS
WILL BE FAIRLY SLOW MOVERS DUE TO WEAK WINDS ALOFT...RAISES THE
POTENTIAL FOR LOCALLY HEAVY RAINFALL. WL HIGHLIGHT THIS POTENTIAL
ACRS OUR SRN ZONES FOR NOW.  MODELS STILL COOLING THE FCST AREA DOWN
SLOWLY...AND WITH MORE CLOUD COVER EXPECTED...THIS LOOKS REASONABLE.
HOWEVER...WL BE LEANING TOWARD THE WARMER FAN/FWC NUMBERS AS THE MAV
NUMBERS HAVE BEEN ON THE COOL SIDE THE LAST SEVERAL RUNS.   MOISTURE
HANGS AROUND THE REGION THROUGH MUCH OF THE WEEK WITH THREAT OF
CONVECTION JUST ABOUT EVERYDAY.  CURRENT EXTENDED HAS THIS COVERED...
SO NO CHANGES.

EMERGENCY MANAGERS IN SOUTHWEST COLORADO SHOULD MAINTAIN A HIGH LEVEL
OF WEATHER AWARENESS THROUGH TONIGHT DUE TO SLOW MOVING SHOWERS AND
THUNDERSTORMS.  RAINFALL RATES OF UP TO AN INCH AN HOUR WILL BE
POSSIBLE WITH THE STRONGER THUNDERSTORMS...LEADING TO THE POTENTIAL
FOR FLASH FLOODING AND/OR ROCK AND MUD SLIDES. OTHER EMERGENCY
MANAGERS IN WESTERN COLORADO AND EASTERN UTAH SHOULD MAINTAIN A
HEIGHTENED LEVEL OF WEATHER AWARENESS THROUGH TONIGHT DUE TO
SCATTERED SHOWERS AND THUNDERSTORMS.
