...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS OVER PARTS OF
FLORIDA...SOUTHERN GEORGIA AND ALABAMA...AND INTO CENTRAL MONTANA...

...SUMMARY...
Strong thunderstorms may impact parts of northern and central
Florida and adjacent southern Georgia and Alabama on Saturday.
Additional strong thunderstorms may impact parts of western into
central Montana.

...Synopsis...
An upper cyclone will remain over the Sabine Valley, with cold air
aloft extending from TX toward the northern Gulf Coast. At the
surface, low pressure will move from the northern Gulf into LA/MS,
with a stationary front over southern AL and GA. A moist and
unstable air mass will exist south of this boundary, supporting
bouts of thunderstorms.

To the west, strong southwest winds aloft will spread across the
Pacific Northwest and into ID and western MT late. Heating within a
surface trough over western MT combined with cooling aloft may
support scattered high based storms.

...FL into far southern GA/AL...
Numerous storms are forecast over parts of the Gulf Of America and
extending from southern AL into the FL Panhandle during the day.
Associated outflows may be strong given the amount of convection.
Veering winds with height in the low levels may support rotation at
times, and a brief tornado cannot be ruled out along the stationary
front.

During the afternoon, strong heating will lead to storms from
central FL into southern GA, and cool temperatures aloft may favor
sporadic hail.

...West-central MT...
Scattered fast-moving storms are forecast after about 21Z along the
ID/MT border and spreading from western into north-central MT. While
high based, steep lapse rates along with favorable mean winds/deep
shear will support both strong to severe gusts and marginal hail.
