...Showers and T-storoms Today; Heavy Rain Possible! Excessive Heat Warning West...

It will be hot and muggy once again today, though there will be scattered storms around to provide some relief.

Excessive Heat Warning in effect through early this evening in the west and west-central along with a Heat Advisory in parts of south-central Kentucky. For the remainder of the Bluegrass state, a band of thunderstorms with very heavy rain and numerous lightning strikes will continue eastward today. Some ponding of water will be possible with these storms.

This will push the livestock heat stress index into the danger to emergency category across the west sections of the state. Livestock, horses, and pets will all be susceptible during this period. Producers are urged to take precautions.

The trend for the upcoming week is for more normal temperatures and humidity levels. Though isolated storms will be possible most days, the best chance for rain will be Thursday and Friday.

Weather History...

A weather diary kept by George Washington recorded that the center of a
hurricane passed directly over his Mount Vernon home. The hurricane crossed
eastern North Carolina and Virginia before moving into the Central
Appalachians. Norfolk VA reported houses destroyed, trees uprooted, and
crops leveled to the ground. (David Ludlum)
A two hour thunderstorm deluged Atlanta GA with 4.32 inches of rain. More
than a foot of water flooded Union Depot. Many street car motors burned out
while trying to run through flooded streets. It grew so dark before the
afternoon storm that gas lights were needed. (The Weather Channel)
Sheridan WY was drenched with 4.41 inches of rain, an all-time 24 hour
record for that location. Associated flooding washed out 20 miles of
railroad track. (22nd-23rd) (The Weather Channel)
Thunderstorms produced a record ten inches of rain in six and a half hours
at Minneapolis MN, including 5.26 inches in two hours. Flash flooding
claimed two lives and caused 21.3 million dollars damage. Streets in
Minneapolis became rushing rivers, parking lots became lakes, and storm
sewers spouted like geysers. A tornado hit Maple Grove MN causing five
million dollars damage. Baseball size hail was reported at Olivia MN. (The
National Weather Summary) (Storm Data)
Thunderstorms produced severe weather in Lower Michigan and northern Ohio,
over eastern sections of the Dakotas, and over the Central High Plains
Region. Showers and thunderstorms soaked Wilmington NC with another two
inches of rain, following six and a half inches the previous day. (The
National Weather Summary)
Morning thunderstorms in the central U.S. drenched central Oklahoma with up
to six inches of rain. Afternoon thunderstorms produced wind gusts to 85
mph at Fort Smith AR. Evening thunderstorms over Florida spawned a tornado
which touched down three times in south Fort Myers causing nearly three
quarters of a million dollars damage. (The National Weather Summary) (Storm
