Listed are Meteorological events that happened on May 5th:
Ever wonder how far a lightning discharge can travel? If the lightning is a cloud-to-ground bolt, then the travel distance is limited by the distance from the inside of the cloud to the ground, which is usually less than 10 miles, but a distance of up to 20 miles is not unheard of. Cloud-to-cloud or intracloud discharges my reach for 100 miles or more in rare cases.
This is the average day of the first 100 degree reading at Needles, CA.
A group of tornadoes in Virginia killed three people. The twisters carved a path from near Victoria to south of Petersburg to just south of the James River. The damage path was reportedly one mile wide in places.
The same storm which a day earlier produced eight inches of snow in the Texas panhandle produced over a foot of snow at Denver, CO, their heaviest snow on record for the month of May. 12 inches fell on this date and the greatest 24 hour snowfall for May. Along with the record snow came record low temperatures of 27° on this date and 23° on the 6th.

A line of severe thunderstorms moved through Dade County in south Florida causing extensive tree and power line damage. Several trees fell onto parked cars. This was associated with the same frontal system that moved through northern and central Florida the day before producing many tornadoes, leaving three dead, over 100 injured, and more than $8 million dollars in damage. The hardest-hit areas in Dade County were Coconut Grove, Coral Gables, Kendall and South Miami. More than 75 power lines were broken by falling tree limbs and flying debris.

Flooding also occurred in north Texas, where several roads in Wichita, Clay, and Archer Counties were closed by high water that spilled over the banks of area creeks.
Fresno, CA received 0.01 inch of rain. This was the latest measurable precipitation received for the water season pushing the total to 23.57 inches, the wettest water season on record.

Five tornadoes in North Carolina accounted for five deaths, 88 injuries, and $60 million dollars damage. Thunderstorms also produced baseball size hail at Lake Murray, SC, and wind gusts to 78 mph at Brooklyn, MD.
A strong Pacific cold front moving rapidly inland caused weather conditions at the east end of the Strait of Juan de Fuca in Washington State to quickly change from sunny and calm to westerly winds of 60 mph and 10 foot waves. Three recreational fishing boats capsized in heavy seas off Port Angeles resulting in five deaths.
In California, temperatures soared above 90° across much of the state. The high of 101° in downtown Los Angeles was eight degrees hotter than their previous record for the date. Bakersfield, CA hit 100° and Fresno topped out at 99° to set daily high temperature records.
A four-day sandstorm raged across Mongolia and Northwestern China with hurricane-force winds. Reports of 47 deaths came from Sansu Province in China. As many as 300,000 head of livestock died in Inner Mongolia.
A heavier precipitation supercell thunderstorm rapidly developed just ahead of a fast moving bow echo squall line and blasted Tarrant County, Texas. Large hail up to 5 inches in diameter, driven by 80 mph winds, caused a tremendous amount of damage. 10,000 people were caught out in the open at Mayfest in downtown Forth Worth, resulting in 109 injuries from the large hail. Torrential rains of up to 3 inches in 30 minutes and 5 inches in one hour across Dallas caused unprecedented flash flooding, resulting in 21 deaths and 510 injuries. Total damage in Forth Worth alone was estimated at $2 billion dollars, making this the costliest thunderstorm event in U.S. history. This was the third severe hailstorm to strike the area in only a little over a month.
The Japanese Meteorological Agency named the first typhoon of the season Damrey, using a new multi-national naming list that not only included people's name, but names of animals, astrological signs, fish and even an airport. Damrey is Cambodian for elephant.
On a scary note, a convoy of experienced storm chasers, including Matt Sellers and Shane Adams, had a near-miss with a tornado which touched down nearly on top of them near Lakeview, TX as they were following the storm that had earlier struck the town of Happy. No chasers were injured during the encounter, but several had damage to their vehicles.

A severe thunderstorm struck the Brahmanbaria District of eastern Bangladesh claiming at least 22 lives. Winds gusted as high as 75 mph accompanied by hail and heavy rain, flattened hundreds of mud houses.
A large upper low pressure area over the southwest United States spun off a strong upper level trough into the northern plains. This trough lifting over the region along with a north to south frontal boundary, powerful low level winds, and abundant gulf moisture resulted in training thunderstorms across parts of central and northeast South Dakota. The training thunderstorms produced torrential rains from 3 to over 10 inches resulting in widespread flash flooding across Brown, Buffalo, Hand, Spink, Clark, Day, Marshall, and Roberts Counties. The counties of Brown, Buffalo, Clark, Day, Marshall, and Spink were declared disaster areas by President Bush. The Governor also declared a state of emergency for the flooded counties. Dozens of cities were affected by the flooding with several hundred homes, businesses, and countless roads affected and damaged or destroyed by the flooding. Aberdeen received the most extensive damage, especially the north side of Aberdeen. 75% percent of the homes in Aberdeen received some water in their basements. Basement water levels ranged from a few inches to very deep water all the way up to the first floor of homes. Many homes had basement walls collapse. The overwhelming load on the drainage systems caused sewage to back up into many homes across the region. Also, many vehicles stalled on the roads with many others damaged by the flooding. Power outages also occurred across the area. Many families were displaced from their homes with many living in emergency shelters. Countless homes were condemned across the region with many considered unlivable. Thousands of acres of crops were also flooded and damaged with many seeds and large quantities of fertilizer washed away. Rainfall amounts from this historic event included, 3.65 inches in Miller, 3.82 inches in Britton, 4 inches in Eden, 4.47 inches in Andover, 4.90 inches in Webster, 5.68 inches west of Britton, 5.7 inches in Garden City, and 5.82 inches in Conde.
