(Rest of tonight and Friday)
Issued at 915 PM CDT Thu Jun 4 2026

High pressure remains centered across the Southeast resulting in
tranquil conditions tonight for the Tennessee Valley. Light winds
and mostly clear skies are forecast this evening with the
exception of some high clouds streaming in from the west. With
ideal radiational cooling conditions, temperatures will fall into
the upper 50s to lower 60s. We end the workweek with a beautiful
summer day for early June. Surface high pressure remains to our
east, keeping the upper level ridge over the Southeast. Another
warm day is in store with afternoon temperatures rising into the
low to mid 80s.

.SHORT TERM...
(Friday night through Sunday)
Issued at 915 PM CDT Thu Jun 4 2026

Not much change in the local weather pattern as we head into the
weekend. With high pressure overhead and underneath the
aformentioned upper level ridge, dry and mild conditions are
forecast on Saturday. Expect afternoon highs to warm into the mid
to upper 80s and overnight lows in the mid to upper 60s. By the
second half of the weekend, the sfc high pressure will slowly
shift to the east bringing in a more moisture rich airmass off the
Gulf. As a result, diurnally driven thunderstorms return to the
forecast with low to medium chances (40-60%) on Sunday afternoon.

.LONG TERM...
(Sunday night through Thursday)
Issued at 915 PM CDT Thu Jun 4 2026

High pressure will shift east of the Tennessee Valley next week as an
unsettled pattern returns. Deep southwesterly flow will really begin
to advect in a warm, moist air mass on the western edge of the ridge.
This is evidenced by dewpoints returning to the upper 60s to lower
70s by Sunday. Diurnally driven convection will develop each day
(40-80% chance), with the greatest coverage occurring during the
afternoon and evening hours. Convection on Monday and Tuesday will
also be aided by a passing shortwave trough over the Mid-Mississippi
and Ohio Valleys that will clip our area. Given the moist environment,
all of these storms will be capable of producing locally heavy
downpours. Otherwise, warm/muggy conditions which fairly typical for
early June as daytime highs reach the mid to upper 80s each day.

.AVIATION...
(06Z TAFS)
Issued at 103 AM CDT Fri Jun 5 2026

A broken layer of Ci will spread northeastward across northern AL
early in the TAF period, but should begin to disperse later this
morning, permitting sufficient insolation for the development of
sct fair-weather Cu based arnd 4 kft. Although the presence of the
high clouds should not prevent development of patchy BR/FG near
large bodies of water, confidence in vsby reductions at either HSV
or MSL is not high enough to include in the TAFs attm. Sfc winds
will remain calm thru sunrise, but should assume a SSW component
at 5-10 kts by 16Z.
