Historical Weather And Climate Facts For Today

//////////////////////////
JULY 18TH...HISTORIC WEATHER EVENTS
...1889...
A cloudburst in West Virginia along the small creeks in Wirt County,
Jackson County and Wood County claimed twenty lives. Rockport WV reported
nineteen inches of rain in two hours and ten minutes that Thursday evening.
Tygart Creek rose 22 feet in one hour, and villages were swept away on
Tygart, Slate, Tucker, and Sandy Creeks. (The Weather Channel)
...1942...
A record deluge occurred at Smethport in northern Pennsylvania, with 30.7
inches in just six hours. The downpours and resultant flooding in
Pennsylvania were devastating. (David Ludlum)
...1986...
One of the most "photo-genic" tornadoes touched down in the northern
suburbs of Minneapolis MN during the late afternoon. The very slow moving
tornado actually appeared live on the evening news by way of an aerial
video taken by the KARE-TV helicopter crew. The tornado, unlike most, was
quite the prima donna, staying visible to tens of thousands of persons for
thirty minutes. It was moderate in intensity, with winds of 113-157 mph,
and caused 650 thousand dollars damage. (Storm Data)
...1987...
Cool weather prevailed in the western U.S. Seven cities reported record low
temperatures for the date, including Alamosa CO with a reading of 38
degrees. The low of 52 degrees at Bakersfield CA was a record for July. Up
to eight inches of snow covered the Northern Sierra Nevada Range of
California from a storm the previous day. During that storm, winds gusting
to 52 mph at Slide Mountain NV produced a wind chill reading of 20 degrees
below zero. Susanville CA reached 17 degrees that previous day, Blue Canyon
CA dipped to a July record of 36 degrees, and the high of 44 degrees at
Klamath Falls OR smashed their previous record for July by ten degrees.
(The National Weather Summary)
...1988...
Sweltering heat continued in California, with record highs of 111 degrees
at Redding and 112 degrees at Sacramento. Death Valley CA hit 127 degrees.
Late afternoon and evening thunderstorms in the Central Plains Region
produced baseball size hail at Kimball NE, wind gusts to 79 mph at Colby
KS, and six inches of rain near Lexington NE. (The National Weather
Summary) (Storm Data)
...1989...
Thunderstorms produced severe weather in Oklahoma, northern Texas and
Arkansas during the afternoon, and into the night. Thunderstorms produced
baseball size hail at Stamford TX, and wind gusts to 92 mph near
Throckmorton TX. Record heat continued in the southwestern U.S. Phoenix AZ
reported a record high of 115 degrees, and a 111 degree reading at Midland
TX was second only to their all-time record high of 112 degrees established
sixteen days earlier. (The National Weather Summary)
