.SHORT TERM...
(Tonight through Sunday Night)
Issued at 1040 PM CDT Wed Jun 11 2025

Changes are on the way. The mainly sunny, warm, tolerable humidity
pattern we have experienced the past couple of days will be replaced
by a very muggy pattern with medium to high chances for showers and
thunderstorms each day.

An upper level low from Texas will move slowly northeast over the
next several days. At the same time, a high pressure center will
set up along the Florida east coast. The position of these
features will create a very moist southwest flow into Tennessee. A
few showers and storms will begin to pop up here and there
Thursday with coverage increasing Friday. Coverage of showers and
storms will become high area-wide for Saturday and Sunday.
Coverage and intensity each day will peak during the afternoon and
evening hours.

High precipitable water values around 2 inches will lead to some
locally heavy downpours. Not much jumps out in terms of severe wx
parameters, but there will be enough instability (1500-2000 J/kg
cape) for a few brief, localized severe storms each day. These
storms would come with torrential downpours, gusty downburst
winds, and frequent lightning. For the most part, the storms will
be poorly organized with differential heating and small scale
boundaries driving the activity. So other than "mainly afternoon
and evening" it is difficult to offer much in terms of timing for
rain or storms

.LONG TERM...
(Monday through next Thursday)
Issued at 1040 PM CDT Wed Jun 11 2025

The unsettled pattern will continue into the new work week with
mainly afternoon and evening showers and storms continuing. It
look like the coverage of rain will decrease, especially after
Tuesday. But, as rain coverage lessens, heat will build. So, we
could be dealing with very steamy conditions by mid to late week.
Highs may climb into the 90s with heat index values possibly
topping 100 in some areas.
