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.

The nearest sounding before it

Reno, NV (KREV), launched 12:00Z, 0.9 hours before the alert went out and 203 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

NORTHERN GREAT BASIN FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ELKO NV
300 AM PDT FRI MAY 30 2003

STORMS CONTINUE TO FIRE AT THIS HOUR OVER WESTERN NEVADA AND THE
DISORGAINZED BAND IS MOVING SLOWLY EWD. THIS AHEAD OF OPENING UPPER
LOW IN NRN CA. STRONG VORT SEEN ON WV IMAGERY ON SE SIDE OF LOW
WITH JET SUPPORT APPARENT. ONE STORM RATHER STRONG FOR THE OVERNIGHT
PERIOD NOW MOVING INTO SE ORE. MODELS HAVE INITIALIZED THIS FEATURE
WELL...AND AGREE ON TRACK...BUT BELIEVE THEY ARE A LITTLE TOO QUICK
TO SCOUR THE MOISTURE OUT. THIS IS A TYPICAL BIAS...ESP FOR NORTHEAST
ZONES.

FOR NOW...WILL CONTINUE WITH SCT ACTIVITY IN HUMBOLDT CTY TO COVER
CURRENT ACTIVITY AND SHOULD QUIET DOWN THERE AROUND NOON. BAND
SHOWLD MOVE EWD. ACTIVITY SHOULD GET STRONGER WITH HEATING. ADDED
FORCING MAY RESULT FROM DIFFERENTIAL HEATING EAST OF CURRENT BAND SO
THERE MAY BE AN EWD JUMP TO THE LINE. WILL GO WITH SCT COVERAGE I-
80 NORTH AND JUST ISO DOWN SOUTH AWAY FROM BEST FORCING. SEVERE
POTENTIAL IS THERE IN LATE MORNING TO EARLY AFTERNOON AND WILL HAVE
TO WATCH. EARLIER THINKING WAS THAT THIS WOULD BE TOO FAR NORTH...
BUT STORMS ARE GETTING STRONGER PER 88D IMAGERY ATTM. GOOD SHEAR...
BUT WITH RELATIVELY DRY LLVLS EXPECT MAINLY MICROBURST POTENTIAL ESP
WITH STORM MOTION OF 35-40 KTS.

AFTER TODAY...NOT MUCH TO TALK ABOUT AS FLOW VEERS TO THE WEST AND
SHOULD DRY ALL AREAS OUT BY MIDNIGHT. ONLY TOKEN POPS IN THE
NORTHEAST THIS EVENING AS DRYING SHOULD WORK IN QUICKLY. GENERAL
WEST FLOW UNDER FLAT RIDGE THIS WEEKEND WITH TEMPS ABOUT 10-15 DEGS
COOLER THAN PAST COUPLE DAYS BUT STILL ABOVE NORMAL.

EXTENDED...RIDGE TO AMPLIFY A BIT OVER THE WEEKEND JUST OFF THE
COAST. MAY HAVE SOME MORE NW FLOW FOR COOLER TEMPS...BUT NOT SURE.
RIDGE MAY BREAK DOWN ENOUGH FOR BAJA UPPER LOW TO PUSH MOISTURE
NORTH BUT DONT EXPECT THIS TO HAPPEN UNTIL AT LEAST NEXT WEEKEND.
