...New UPDATE...
.KEY MESSAGES...
Updated at 657 PM CDT Sun Jun 7 2026
- Periodic showers and thunderstorms this week with low severe
storm chances.
- Biggest concern this week revolves around a medium flash
flooding potential. A Flash Flood Watch is in effect for Monday
from 6 am to 8 pm.
- Hot and humid conditions this week as heat indices reach the

.UPDATE...
Issued at 657 PM CDT Sun Jun 7 2026
Rain continues to pivot into our area this evening. Very little
lightning with these showers, and that threat should continue to
decrease overnight. Forecast remains on track.
&&
.SHORT TERM...
(Rest of today through Monday)
Issued at 1124 AM CDT Sun Jun 7 2026
A wet pattern is underway today as high pressure shifts offshore
and a surface boundary develops across the region, supported by a
trough to the west. Showers and thunderstorms are ongoing S of
I-65 and will continue to push N through Middle TN this afternoon
and evening. The overall risk of severe weather remains low. Any
isolated stronger storms could bring gusty winds, lightning, and
heavy rainfall. Heavy rainfall is the primary concern due to high
PWAT values, which could lead to localized flooding in heavier
downpours.
Highs today reach the mid to upper 80s, with overnight lows in the
low to mid 70s. Monday looks similar, with showers and thunderstorms
likely, with highs in the low to mid 80s. There is a low chance for
severe weather W of I-65 during this time. Main threats will be
heavy rain and the potential for strong damaging winds. Localized
flash flooding will once again be the main concern.
&&
.LONG TERM...
(Monday Night through next Sunday)
Issued at 1124 AM CDT Sun Jun 7 2026
Unsettled conditions persist into early next week before
transitioning to a more typical summertime regime. Monday night
into Tuesday will feature continued showers and thunderstorm
chances, with highest activity through the morning and afternoon.
Temperatures warm as highs climb into the upper 80s to low/mid
90s by Wednesday through Saturday (some 90+ days). Dew points
remain elevated, pushing heat indices into the mid to upper 90s
and potentially near 100 at times by mid week.
&&
.AVIATION...
(00Z TAFS)
Issued at 630 PM CDT Sun Jun 7 2026
VFR conditions expected for a few more hours before MVFR, then IFR
cats move into mid-state terminals. IFR should last through mid-
morning Monday, then improve to MVFR after additional shower and
TS opportunities. Another chance for afternoon showers and storms
covered with PROB30 at this time.
