...Severe Weather Expected Today, Heat Advisory West...

According to the latest weather forecasts, an outbreak of severe weather is likely this afternoon and evening across Kentucky. The Storm Prediction Center has a large portion of our area in a "Moderate Risk" (level 4 out of 5 severe risk). Damaging winds, very large hail (> 2+ inches in some instances), and a few tornadoes are possible.

An unseasonably strong storm system will move into the lower Great Lakes through this evening, with a surface cold front trailing from this system also approaching our region by later this evening. The strong storm system will interact with a strongly unstable airmass to develop numerous strong to severe storms. Large hail, damaging winds, and a few tornadoes are all possible along with excessive lightning and heavy rainfall. The most widespread period of storms will be from late this afternoon through late evening. The storms should be out of the area midnight. Scattered showers and storms are then possible mainly each afternoon and evening through the weekend, although aren't expected to be as strong as today.

In addition to the potential for severe weather, western sections of the state also have a Heat Advisory in effect. The heat will be the main threat for today with southern portions of the region exceeding triple digit heat index values. Livestock Heat Stress will rise into the Emergency Category in the west and Danger Category for the remainder of the state.

////////////////////////
JULY 20TH...HISTORIC WEATHER EVENTS
...1930...
The temperature at Washington D.C. soared to an all-time record of 106
degrees. The next day Millsboro reached 110 degrees to set a record for the
state of Delaware. July 1930 was one of the hottest and driest summers in
the U.S., particularly in the Missouri Valley where severe drought
conditions developed. Toward the end of the month state records were set
for Kentucky with 114 degrees, and Mississippi with 115 degrees. (David
Ludlum)
...1934...
The temperature at Keokuk IA soared to 118 degrees to establish a state
record. (The Weather Channel)
...1953...
Twenty-two inches of hail reportedly fell northeast of Dickinson ND. (The
Weather Channel)
...1986...
The temperature at Charleston SC hit 104 degrees for the second day in a
row to tie their all-time record high. (The Weather Channel)
...1987...
Thunderstorms produced severe weather across Minnesota, Wisconsin and
Michigan. Thunderstorms produced wind gusts to 87 mph at Mosinee WI, and
strong thunderstorm winds capsized twenty-six boats on Grand Traverse Bay
drowning two women. Thunderstorms produced nine inches of rain at Shakopee
MN, with 7.83 inches reported in six hours at Chaska MN. Thunderstorms in
north central Nebraska produced hail as large as golf balls in southwestern
Cherry County, which accumulated to a depth of 12 inches. (The National
Weather Summary) (Storm Data)
...1988...
The temperature at Redding CA soared to an all-time record high of 118
degrees. Showers and thunderstorms produced much needed rains from New
England to southern Texas. Salem IN was deluged with 7.2 inches of rain
resulting in flash flooding. (The National Weather Summary)
...1989...
Showers and thunderstorms in the Middle Atlantic Coast Region soaked
Wilmington DE with 2.28 inches of rain, pushing their total for the period
May through July past the previous record of 22.43 inches. Heavy rain over
that three month period virtually wiped out a 16.82 inch deficit which had
been building since drought conditions began in 1985. Thunderstorms in
central Indiana deluged Lebanon with 6.50 inches of rain in twelve hours,
and thunderstorms over Florida produced wind gusts to 84 mph at Flagler
Beach. (The National Weather Summary) (Storm Data)
