Listed are Meteorological events that happened on July 16th:
Beginning on the 15th ending on this date, North Carolina registered its record maximum 24 hour precipitation record as 22.22 inches fell at Altapass.
Lillooet and Lytton set British Columbia, Canada’s all-time high temperature mark with 112°.
An unusual tornado touched down at Churdan, IA and moved west-northwest slowly after touchdown.
The strongest and most destructive tornado known in Wyoming history struck Cheyenne. The F4 tornado initially touched down just northwest of the airport and proceeded to move east over residential areas along Buffalo Ridge. A young boy was killed while 57 others residents were injured. Approximately 140 homes were destroyed along with the local elementary school, while approximately 200 other homes were damaged. Total damage was $22 million.
Millions of dollars in damage was done by a strong microburst and blinding rain that hit the south side of Chicago, IL during the morning. Winds were estimated to be as high as 100 mph in the microburst. Further west, the same storm system produced a tornado near the town of Hampshire, destroying two silos containing 48,000 pounds of corn.
Severe thunderstorms moved rapidly across the region during the late afternoon causing widespread damage. Bensalem, PA reported a wind gust of 102 mph. Philadelphia, PA measured a sustained wind speed of 47 mph with a gust to 70 mph. Thousands of trees were uprooted or broken apart, falling on automobiles, houses and other buildings. Up to 24 people were injured, mostly the result of flying debris, such as glass from blown out windows, portions of buildings or roofs, and falling or blowing limbs or trees. Hail up to the size of golf balls fell, and heavy downpours caused up to 3 inches of rain in spots.
The overnight low in Washington, D.C. only dropped to 84°, their warmest minimum temperature reading ever.
This was a wild day across parts of northeastern South Dakota, southwestern Minnesota and northwestern Iowa as a line of thunderstorms moved southward bringing tornadoes, strong winds and hail. A trailer was destroyed by winds of 70 mph in Palo Alto County at Emmetsburg. In Jackson County of southwest Minnesota, a tornado struck two farm sites and caused minor damage to the homes and more extensive damage to the outbuildings. This tornadic cell then moved southward into Dickinson and Emmet Counties of northwest Iowa, but no damage was reported in these areas. Much of the rest of southwest Minnesota saw high thunderstorm winds and hail flatten corn and bean crops. In Sioux Falls, SD high winds gusted to 64 mph causing some tree damage. Further south in Yankton and Clay Counties winds gusted to 75 mph causing property damage to grain bins. The damage then continued across the Missouri River in Cedar and Thurston Counties of northeast Nebraska.
A plane carrying executives from Holland to Muskegon, MI crashed while landing in heavy fog. The pilot had descended below approach minimums and the plane struck two trees about two miles short of the runway. Three people were killed, including the pilot. Three others were injured.
Showers and thunderstorms in the southwestern U.S. ended a record string of 39 consecutive days of 100 degree heat at Tucson, AZ. A thunderstorm at Bullhead City, AZ produced wind gusts to 70 mph reducing the visibility to near zero in blowing dust. Southerly winds gusting to 40 mph pushed temperature readings above 100 degrees in the Northern Plains. Rapid City, SD reported a record high of 106°, following a record low of 39° just three days earlier.
Many cities in the eastern U.S. reported record high temperatures for the date. Highs of 96° at Bluefield, WV and 104° at Charleston, WV were all-time records, and afternoon highs of 98° at Binghamton, NY, 99° at Elkins, WV, and 103° at Pittsburgh, PA, tied all- time records. Highs of 104° at Baltimore, MD and 105° at Parkersburg, WV were records for July, and Beckley, WV equaled their record for July with a high of 94°. Martinsburg, WV was the hot spot in the nation with a reading of 107°.
Showers and thunderstorms developing along a stationary front drenched the Mid- Atlantic Coast States with heavy rain, causing flooding in some areas. More than five inches of rain was reported near Madison and Ferncliff, VA.
Hot weather prevailed in Texas. San Angelo reported a record high of 106°.
The Great Midwest Flood continued as all bridges across the Mississippi River between Burlington, IA and St. Louis, MO; a stretch of 212 miles were closed by the flooding and would be shut down until the 20th.
Across eastern South Dakota from the 16th through the 18th, flooding continued to wreak havoc. Rainfall amounts of 2 to 7 inches fell across portions of the northeast resulting in devastating flooding. Several dams and many roads were washed out in Marshall County. The heavy rains resulted in flooded farmland, roads, and basements. In the towns of Groton and Claremont at least 90% of the homes had water in the basements and city streets were breaking apart due to the weight of the water and water undermining the roads.
An emergency dike broke near Milbank which sent water into the town. The breach forced the evacuation of over 200 people as 120 mobile homes and over 25 houses were affected by floodwater.
A Mesoscale Convective Complex crossed the Adirondack Mountains and much of eastern New York during the early morning hours and bolted southeast, producing a very damaging derecho. The Adirondack Derecho was produced by thunderstorms which rose to heights of 70,000 feet, moved at forward speeds of 70 mph, produced winds to 106 mph and causing as many as 3,000 lightning strikes per hour. Across western New York, thunderstorm winds caused widespread damage, downing trees and wires. Hardest hit were the counties of Jefferson and Lewis where states of emergency were declared. In some cases, these structures were tossed hundreds of feet and debris was scattered over a half mile away. Permanent structures suffered considerable roof damage. Power was knocked out in all of Jefferson and Lewis counties for at least 12 hours, and in some cases, for days. The North Country was declared a disaster area by the Governor of New York State. Thousands of trees covering over one million acres were blown down in the Adirondacks. Five people were killed. Otis, MA recorded a wind gust of 92 mph. Small tornadoes were reported at Greenfield and Huntington, MA.
A dramatic and mysterious cooling of waters in the northeast Gulf of Mexico killed fish and chilled swimmers along the beaches of the Florida Panhandle. Coastal water temperatures from near the Alabama line to Panama City, FL., plunged suddenly from the upper 80s to the low 70s, the kind of surf temperatures that could be expected off of Cape Cod in mid-July. The clear, cold water killed all fish life with its extraordinarily low levels of dissolved oxygen. The best scientific hypothesis was that the cold water has up-welled from the DeSoto Canyon about 30 miles off of the Panhandle.
Death Valley/Furnace Creek, CA reached 127°. This is only one degree lower than their record high of 128° since 1913. Death Valley/Greenland Ranch had five daily maximums ranging from 129° to 134° in July, 1913, but these extremely high observations are not supported by the maximums at surrounding stations during the same period. Trustworthy readings of 128° were attained in Death Valley in July 1972, and in June 1994. In June, 1994, a park ranger measured 131° at Badwater in Death Valley with a sling psychrometer. Badwater is typically a few degrees hotter than Furnace Creek on summer afternoons. Other memorable readings from this very hot day: 126° at Bullhead City, AZ. Las Vegas, NV reached 116°, just one degree shy of its all-time maximum of 117°. Daily records: Borrego Springs, CA: 118°, Escondido, CA: 102°.
Fresno & Bakersfield, CA experienced their latest first 100-degree day on record. On the same day, Tehachapi, CA hit 100° for the first time since 7/26/1980.
Typhoon Halong twice made landfall near Tokyo, Japan but by-passed the city. The combination of winds and rains injured nine people, damaged over 150 homes and triggered landslides.
Casper, WY tied their daily record high at 104°. Denver, CO soared to a record of 102°. This record high was broken the next year.
The mercury at Valentine, NE soared to 113° establishing a new record high for the date. Denver, CO broke their high temperature record set just the previous year with 103°.
