The streak is over! We only reached 93 yesterday, breaking 3 days in 
a row of record tying high temperatures. Fortunately, it looks like 
the next few day's records are also safe as we should remain a 
couple of degrees below them. It'll still be hot with low 90s each 
of the next 3 days. This persistence also pertains to the rain. The 
upper ridge responsible for these hot temperatures will start to 
weaken a little each day and by Wednesday, we should be into a 
southwesterly flow aloft. This could open the door for a diurnal 
thunderstorm, but I'm going to maintain the dry forecast as the 
subsidence should win out one final day.

Thursday is the day when I think the subsidence will finally be 
overcome and we'll get a slight airmass change. A low pressure 
system is expected to develop near Oklahoma and push northeastward 
into the Ohio River valley Wednesday night. By Thursday 
afternoon, a weak, diffuse frontal system should reach Middle TN 
and we should see some scattered thunderstorms. Helicities are 
still very low, but with a (meager) forcing mechanism, plenty of 
instability and 40 kts of deep layer shear, we should be able to 
squeeze out a few spots of convection. I'm less impressed with 
Thursday's forecast soundings than I was last night, so we're just
talking about general thunderstorms for now.

This "front" should washout as it makes it over to the Cumberland 
Plateau Thursday evening and going into Friday, we completely lose 
the influence of the upper level ridge. A very zonal pattern sets up 
and should be with us into the weekend. I'm of the belief that this 
will create the opportunity for diurnal convection each 
afternoon/early evening starting Friday, but the models are 
showing an extremely muddled mix of QPF both day and night. I'll 
mold the extended PoP forecast around the thoughts of the diurnal 
activity and we'll adjust throughout the week. Hopefully we can 
get a better signal by mid-week. Either way, this new upper level 
pattern should allow us to only top out in the upper 80s next 
weekend and into the start of next week.

A massive tornado struck Saint Louis MO killing 306 persons and causing
thirteen million dollars damage. The tornado path was short, but cut across
a densely populated area. It touched down six miles west of Eads Bridge in
Saint Louis and widened to a mile as it crossed into East Saint Louis. The
tornado was the most destructive of record in the U.S. up until that time.
It pierced a five-eighths inch thick iron sheet with a two by four inch
pine plank. A brilliant display of lightning accompanied the storm. (David
Ludlum) (The Weather Channel)

A tornado struck Louisville, with terrific lightning. (NWS Louisville)

Severe thunderstorms in West Texas produced baseball size hail at Crane,
hail up to three and a half inches in diameter at Post, and grapefruit size
hail south of Midland. Five days of flooding commenced in Oklahoma.
Thunderstorms produced 7 to 9 inches of rain in central Oklahoma. Oklahoma
City reported 4.33 inches of rain in six hours. Up to six inches of rain
caused flooding in north central Texas. (The National Weather Summary)
