.NEAR TERM...
(Today)
Issued at 200 AM CDT Fri Jul 4 2025

A clear and calm night was underway. Patchy fog has developed in
parts of north MS and southern middle TN, but thus far has avoided
our forecast area. A few local spots may experience fog this
morning, but those will be far and few between. A sunny and hot
July 4th is forecast with highs of 90-95 in valley areas, and
upper 80s atop the higher elevations of the Cumberland
Plateau. A weak 5h trough will be drifting south through the area
today, while an inverted surface/8h trough axis shifts west from
GA into AL. A few cumulus are expected with this feature, and CAMS
are showing isolated cells developing. At this point, the chance
of precipitation will be less than 10%, so have left a dry
forecast, but will advise the day shift to make a reassessment
this morning.

.SHORT TERM...
(Friday night through Sunday)
Issued at 1047 PM CDT Thu Jul 3 2025

We will maintain a dry but hot forecast through the weekend under
the influence of high pressure as there is little change in the
overall synoptic pattern. Highs will reach the low to mid 90s each
day and the biggest impact will be afternoon heat indices near or
just above 100 degrees. With overnight lows in the lower 70s,
this will provide very little relief from the heat during the day.
While it does not look like Heat Advisory criteria will be met at
this point, that could change. 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...
(Sunday night through Thursday)
Issued at 1047 PM CDT Thu Jul 3 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.
