.KEY MESSAGES...
Updated at 1201 PM CDT Fri May 2 2025

- Strong to severe thunderstorms possible this afternoon and

  concerns. Tornado and flooding threat is low.

.SHORT TERM...
(Rest of today through Saturday)
Issued at 1047 AM CDT Fri May 2 2025

A line of strong to severe storms is nearing the Tennessee River,
with a second line of equally potent storms currently pushing
through eastern Arkansas. So it could be a long afternoon and
evening across Middle Tennessee. The environment across the area
is definitely unstable. CAPE values well in excess of 2,000 J/kg
cover the entire mid state, and the morning sounding from OHX
showed a 700-500 mb lapse rate of 7.3C/km. So the potential for
strong updrafts is definitely there, even if shear values and
helicities are relatively weak. It is possible that the existing
severe thunderstorm watch could be extended beyond the current
expiration time of 22Z, especially for eastern portions of Middle
Tennessee, if the storms maintain their strength. At any rate, a
cold front will come through the area tomorrow morning, so rain
and storms chances will taper off by the afternoon. Still, most of
Middle Tennessee remains under a marginal risk of severe storms
on day 2, but the risk is much lower than today. With the fropa
occurring on Saturday, cooler temperatures will spread across the
region tomorrow, as well.

&&

.LONG TERM...
(Saturday Night through next Friday)
Issued at 1047 AM CDT Fri May 2 2025

Interestingly, the upper low associated with our weekend weather
system will stay in place just to our north into the early part of
next week. This will help keep cooler air locked in across Middle
Tennessee until about Tuesday, when temperatures will begin a slow
warming trend. Still, values next week will stay close to seasonal
normals. Rain chances will return to the forecast beginning
Tuesday night and Wednesday and lasting through the week.

&&

.AVIATION...
(18Z TAFS)
Issued at 1201 PM CDT Fri May 2 2025

It's going to be an active afternoon and evening across Middle
Tennessee as multiple lines of storms track across the mid state.
We've used TEMPO groups to highlight peak times for convective
activity, although there is less confidence in the timing and
strength of the second line of storms that is just now crossing
the Mississippi River. Rain chances will linger through the night
and into tomorrow, and we expect ceilings to gradually lower to
MVFR and IFR later this evening and into tomorrow morning.
