...Hot And Very Humid Into The Weekend!...

As of 4 PM, the majority of the state is in the low to middle 90s with heat indices over 100. Some in Western Kentucky have heat indices approaching 110. More of the same is expected tomorrow. This will push the livestock heat stress index into the danger to emergency category. Livestock, horses, and pets will all be susceptible during this period. Producers are urged to take precautions. Stay cool!

After isolated chances of showers and storms in the forecast tomorrow, better chances return Sunday and into early next week with the passage of a cold front.

...1896...
Shelbyville, Kentucky's wettest day on record, with 7.15 inches of rain.

persons homeless, and caused an estimated 25 million dollars damage. (David
Ludlum)
...1987...
Thunderstorms produced severe weather from Utah to North Dakota, spawning a
dozen tornadoes in North Dakota. Thunderstorms in North Dakota also
produced baseball size hail at Clifford which caused four million dollars
damage, and high winds which toppled a couple of eighty foot towers cutting
off power to the town of Blanchard. (The National Weather Summary) (Storm
Data)
...1988...
While cool air invaded the central U.S., unseasonably hot weather continued
over the western states. The temperature at Spring Valley NV soared from a
morning low of 35 degrees to an afternoon high of 95 degrees. Fallon NV
reported an all-time record high of 108 degrees, and Death Valley CA
reported their sixth straight day of 120 degree heat. (The Weather Channel)
(The National Weather Summary)
...1989...
Afternoon thunderstorms over Florida produced wind gusts to 92 mph at
Jacksonville, damaging thirteen light planes at Herlong Field. Five cities
in Texas reported record low temperatures for the date. Corpus Christi TX
equalled their record low for the date with a reading of 71 degrees, and
then tied their record high for the date that afternoon with a reading of
97 degrees. (The National Weather Summary) (Storm Data)

After two week's of very hot weather conditions in Kentucky, cool air from
Canada moved into the Bluegrass state and provided temperatures in the upper 70's
and low 80's. (UKAWC)
