.SHORT TERM...
(This evening through Wednesday)
Issued at 115 PM CDT TUE JUN 17 2025

A subtle 500mb trough axis is contributing to weak southwesterly
shear across Alabama today while diurnal heating and low 70s dew
points are supporting a moderately unstable air mass. A few
thunderstorms could reach severe threshold this afternoon and
evening with the primary threat being damaging wind gusts, of
which will be most likely or persistent with clustered activity.
Flow aloft weakens on Wednesday, though the same diurnally
unstable air mass will exist, supporting scattered showers and
thunderstorms.

.LONG TERM...
(Wednesday night through next Monday)
Issued at 115 PM CDT TUE JUN 17 2025

A 500mb trough swinging across the Midwest on Thursday may provide
a corridor of modest shear across northeast Alabama as conditions
become more unstable area-wide through the day. In the area of
weak shear, storms may reach severe threshold with the primary
threat being damaging wind gusts.

A ridging pattern will then take hold for several days. The
coverage of daily showers and thunderstorms should decrease,
though not vacate the region, while temperatures and the risk for heat
stress rise.

taper down some. MVFR cigs will develop/move into the area after

16-18z toward the end of the period.

A disturbed pattern will remain across the area, with showers and
thunderstorms remaining in the forecast through the weekend.

50% during this timeframe as well.
