AUGUST 6TH, 1959 |
A bucket survey showed that thunderstorms dropped 16.70 inches of rain on parts of Decatur County IA. The total was accepted as Iowa's 24 hour rainfall record. |
AUGUST 6TH, 1918 |
Unusually hot weather began to overspread the Atlantic Coast States, from the Carolinas to southern New England. The temp- erature soared to an all-time record high of 106 degrees at Washington D.C., and Cumberland and Keedysville hit 109 degrees to establish a state record for Maryland. Temperatures were above normal east of the Rockies that month, with readings much above normal in the Lower Missouri Valley. Omaha NE reached 110 degrees. |
AUGUST 5TH, 1843 |
A spectacular cloudburst near Philadelphia turned the small creeks and streams entering the Delaware River into raging torrents. As much as sixteen inches of rain fell in just three hours. Flooding destroyed thirty-two county bridges, and caused nineteen deaths. It is believed that several small tornadoes accompanied the torrential rains, one of which upset and sank more than thirty barges on the Schuylkill River. |
AUGUST 5TH, 1961 |
The temperature at Ice Harbor Dam WA soared to 118 degrees to equal the state record established at Wahluke on the 24th of July in 1928. The afternoon high of 111 degrees at Havre MT was an all-time record for that location. |
AUGUST 4TH, 1882 |
A vivid aurora was visible from Oregon to Maine, down the east coast as far as Mayport FL, and inland as far as Wellington KS. Observers at Louisville KY noted "merry dancers" across the sky, and observers at Saint Vincent MN noted it was probably the most brilliant ever seen at that location. |
AUGUST 4TH, 1930 |
The temperature at Moorefield WV soared to 112 degrees to establish a state record, having reached 110 degrees the previous day. Widespread drought after April of that year caused some towns to haul water for domestic use, and many manufacturing plants were barely operational. |
AUGUST 3RD, 1970 |
Hurricane Celia comes ashore in the Corpus Christi area with wind gusts to 161 mph, causing 11 deaths and property losses totaling $454 million. |
AUGUST 3RD, 1885 |
A tornado hit Philadelphia and Camden along its eight mile path. |
AUGUST 2ND, 1975 |
It's a hot time in eastern New England as all time heat records are broken. Massachusetts sizzles as the mercury soars to 107 F (42 C); Maine and New Hampshire swelter at 105 F (41 C) and Rhode Island bakes at 104 F (40 C). |
AUGUST 2ND, 1954 |
Severe thunderstorms produced golf ball size hail for thirty minutes in north central Kansas. One drift measured 200 feet long, seventy feet wide and three feet deep. |
AUGUST 1ST, 1985 |
A nearly stationary thunderstorm deluged Cheyenne WY with rain and hail. Six inches of rain fell in six hours producing the most damaging flash flood of record for the state. Two to five feet of hail covered the ground following the storm, which claimed twelve lives, and caused 65 million dollars property damage. |
