When it was near Moore, OK, a truck-mounted Doppler radar measured a wind speed of 318 mph, the highest ever observed in a tornado and close to being the first F6 ever officially recorded.

Opryland Hotel has a foot of water in it and Briley Parkway is completely flooded between McGavock Pike and Two Rivers exit. The entire MetroCenter area, which houses the Titan's practice facility among other businesses, has been evacuated. Nashville mayor, Karl Dean, is calling for residents to curtail use of water as much as possible.

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. 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. Many homes had basement walls collapse. The overwhelming load on the drainage systems caused sewage to back up into many homes across the region. 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. Locations with 6 or more inches of rain included, 6 inches in Langford, 6.33 inches in Gann Valley, 6.72 inches in Clark, 7.41 inches in Ashton, 7.49 inches in Stratford, 7.55 inches near Mellette, 7.97 inches in Aberdeen, 8.02 inches in Redfield, 8.73 inches in Columbia, and 8.74 inches in Groton. The 8.74 inches of rainfall in Groton set a new 24 hour state rainfall record.

As a mother and daughter were driving to a more substantial shelter from their mobile home in Logan, IA when a tornado began to overtake their car. They followed the old advice of seeking shelter in a ditch. As they huddled in the ditch, a large piece of farm equipment and a car fell on them, killing the daughter and injuring the mother.

THIS IS THE WORST FLOOD RICHMOND HAS EVER HAD IN ITS LONG HISTORY !!Floodwallpic.jpg
A wall of water came roaring down the James River valley following ten to twelve days of intensive rain. As water swept through Richmond, buildings, boats, animals, and vegetation were lost. About one hundred fifty people were killed as the river reached a flood stage of forty-five feet above normal. A monument to the flood was inscribed by Ryland Randolph, of Curles, in 1771-72: " ... all the great rivers of this country were swept by inundations never before experienced which changed the face of nature and left traces of violence that will remain for ages." There is a recent publication that discusses the1771 flood. The book is entitled Historical Climate Variability and Impacts in North America and edited by Lesley-Ann Dupigny-Giroux and Gary J. Mock. This book has a 26 page chapter about the 1771 Flood. The chapter is entitled "The Great Flood of 1771: An Explanation of Natural Causes and Social Effects".

On the evening of May 27, 2017, a thunderstorm approached the Springfield Park area from the west southwest coming roughly down Route 64. At 5:36 PM Glen Allen had a wind gust to 29 mph that was followed by the beginning of small hail that was approximately 0.5 inches in diameter and lasted for about one minute. At 5:38 PM large hail began to fall that was approximately 1.25 to 1.5 inches in diameter. Note the time on the radar capture image is 5:38 PM and you can see the area of hail at its maximum diameter here was bounded by Nuckols Road on the north, Springfield Road on the east, Broad Street on the south, and Innsbrook on the west. The Springfield Park Glen Allen station is located at the center of this perimeter. Some of the hailstones were flat like platelets about three quarters of an inch thick and they were even larger some upwards to 2 inches. See image three. Our area was fortunate however because the large hail soon tapered back to inch in approximately 1 minute. The hail stopped by 5:40 PM and only the rain continued. The rain ended at 6:25 PM but was soon followed by a second thunderstorm giving rain from 6:35 PM and ended at 11:35 PM as the second thunderstorm was followed by general area of rain. Pictures G1 through G3 show the distribution of hailstones during this three minutes. But all three of these images were taken approximately 5 minutes after the hail stopped. The largest hailstones were about the size of a golf ball. Number 4 was more spherical, what most people would think of when envisioning hailstones and about an inch and a half in diameter. Number 5 is also rather spherical but had jagged points and was also about 1.5 inches in diameter. Number 6 was only about 1.25 inches in diameter but was one of the more interesting disks as it had a white core, an area that was rather clear and a very clear perimeter. Number 7 was very similar to 5 but a different hailstone. Number 8 was about 1.5 inches in diameter and again seems to form from hailstones coalescing into a conglomerate. Number 9 showed the clearest premature circle of ice which meant that it had fallen through some super cooled air and water coating the stone and froze more slowly giving the clear ice. The 9 hailstones shown gives one an idea of how their shapes varied. This was the largest hail that the Glen Allen Station has recorded in its past 8 years of existence.
