Forecast is still on track for a good evening/night of grilling,
outdoor activities and fireworks. A few thunderstorms have
developed late this afternoon near and east of the I-65 corridor
along a weak boundary extending from southern Alabama to near the
I-65 corridor. Abundant sunshine has allowed highs to climb to
between 93 and 96 degrees in many areas. Additional shower
activity that develops is expected to dissipate at or shortly
after sunset, leaving mostly clear skies in place. Light and
variable winds will persist, and temperatures at firework time
will be around 80 degrees.

.SHORT TERM...
(Saturday night through Monday)
Issued at 1010 PM CDT Fri Jul 4 2025

A series of shortwaves will round the ridge of high pressure in
place, weakening it through the weekend. However, it will still be
able to hold onto keeping us mostly dry and hot through the
holiday weekend. By Monday, we will see the return of diurnally
driven convection (low chances of ~20%) and a cold front will
start to slide southward into the Mid MS Valley and OH Valley that
will play a role in our weather mid week.

Highs this weekend into Monday will be in the 89 to 96 degree
range primarily (upper 80s mainly in higher elevations) while
overnight lows will in the upper 60 to lower 70s. With an
increase in moisture during this time, heat index values will
climb back up into the upper 90s to lower 100s. As for this
forecast package, seems like it will remain below Heat Advisory
criteria of 105, however trends will be monitored. Regardless,
heat safety will remain important for everyone. Enjoy your holiday
weekend but continue to practice heat safety by never leaving
people or pets in vehicles, drink water and seek shade.

.LONG TERM...
(Monday night through Friday)
Issued at 1010 PM CDT Fri Jul 4 2025

High pressure will begin to break down just of the Atlantic coast
and begin building more over the Gulf to begin the work week.
This will ultimately result in increasing chances for diurnally
driven showers and storms beginning Monday. A weak frontal
boundary may begin to approach the area as early as Tuesday into
Wednesday, with PoPs increasing to 40-60% mainly focused during
the afternoon and evening hours. Chances will increase closer to
the frontal boundary on Thursday when it appears the front will
push through the TN Valley. Although not currently outlooked for
severe weather, some of these storms could be strong especially
toward the later half of the week. Heat will continue to be a
threat as afternoon heat indices remain between 100 and 105 each
day. Flooding may have to be monitored towards the end of next
week.

.AVIATION...
(00Z TAFS)
Issued at 636 PM CDT Fri Jul 4 2025

Skies should clear quickly after sunset. There is some question if
an isolated storm could linger into the early evening hours, but
confidence is too low to include. Light winds are expected
overnight. However, advection of drier air from the east overnight
in the boundary layer should keep fog at bay. Winds will pick up
to between 5 and 10 knots with some gusts between 10 and 15 knots
possible in the afternoon. VFR conditions are expected through the
TAF period.
