Discussion...

How hot is it? Its so hot that... never mind maybe i'll continue
that discussion on twitter.

Temperatures are on average 2 degrees warmer than we were at this
time last night. It appears we will flirt with record high minimum
temperatures once again this morning as portions of the midsouth
will likely remain in the 80s. No changes to the heat
advisory/excessive heat warning tonight. Dangerous heat indices
are expected area wide once again today, in excess of 105 degrees
with the hottest locations near or slightly above 110 degrees.

An amplifying ridge over The Rockies will translate to a
deepening trough over the Midwest resulting in cooler conditions
across the eastern half of the nation including the midsouth
tomorrow into early next week. Additionally we will see enhanced
rain chances over the next few days. However, by midweek, the
ridge over The Rockies will shift east resulting in the return of
hot and dry conditions. Guidance has trended warmer after midweek.
Unfortunately it looks like we may be dealing with heat advisory
conditions once again by Wednesday.
