.SHORT TERM...
(Rest of today through Tuesday)
Issued at 1145 AM CDT Mon May 4 2026

We`re in a broad split-flow aloft today, and relatively zonal, as
we transition in the upper-levels through tomorrow. This
coincides with a low-level ridge building off to our southeast
which is promoting a strengthening southerly breeze and warmer
temperatures this afternoon.

By tomorrow morning a cold front will move southeast from the
Upper Midwest toward the Ohio Valley. Continued southerly to
southwesterly low-level flow is expected across Middle Tennessee
which will raise tropospheric moisture values and humidity at the
surface. PWs in the 1.4" to 1.6" are expected to move in from the
west. Meanwhile, a weak surface low is forecast to propagate east
along the stalling front throughout the day. This should bring
scattered convection closer to Middle Tennessee, near the moisture
axis. This is good news considering we need any rain we can
possibly get. We don`t expect any severe weather or flooding with
this initial round of rain/storms.

.LONG TERM...
(Tuesday Night through next Monday)
Issued at 1145 AM CDT Mon May 4 2026

It looks like the best overall chances for rain and storms will be
tomorrow night into Wednesday as the front gradually moves closer
to Middle Tennessee with subsequent shortwave disturbances aloft
expected. These will encourage additional convective development
along the moisture/instability axis. There`s still some
uncertainty about storm evolution on Wednesday as showers and
storms will be possible along the stalled front, but it`s unclear
how much recovery can occur along/south of the front to foster
strong to severe storms. Best overall chances for a severe storm
will be south of I-40 on Wednesday. We`ll also watching for any
training storms that may produce locally heavy rainfall and
flooding. This would be an isolated occurrence given that ongoing
drought is a big inhibitor to any organized flooding concerns.
However, any high rainfall rates, especially in urban or poor-
drainage areas, could result in minor flooding.

This front will finally be nudged out of the region on Thursday
with a large dip in the Polar jet swinging through. We`ll have a
period of cooler, stable weather to finish off the week, though
low rain chances are back in the forecast early next week.
