.DISCUSSION...

Hot and steamy again this morning. We're creeping up on 90 at BNA
and it's not even 10 am. The big question is whether or not anyone
will see relief from today's heat. I think the answer is no for
most everyone, however the wild card is going to be the remnants
of Danny. Currently centered over Central Alabama, radar is
showing that some northward development is finally starting. Hi-res
models haven't been handling this progression well so far this
morning, but now that we're starting to see some of this convection
in northern Alabama, I've tweaked PoPs to try and cover this
trend over the next few hours, with scattered storms starting to
spread into our southern counties over the next hour or so, and
further northward progression into the early afternoon hours.
Again, I don't expect everyone to see rain today, but definitely
more lawns will see some rain than have in the last several days.

Bigger story today will be the continued heat with Heat Indexes
closing in on 100 in many spots, especially across our northern
counties. Find some shade, take breaks and drink water out there!

.AVIATION...
18Z TAF DISCUSSION.

Mostly VFR conditions with occasional MVFR expected with passing
storms this afternoon. With only isolated showers and a few storms
around the Plateau, CSV may be able to get by without any direct
impacts. BNA, MQY, and CKV are likely to see some passing storms
with brief heavy rainfall and gusty winds between now and 01z.
Conditions will become calm overnight with scattered to broken mid
clouds.
