...Synopsis...
Relatively dry and stable conditions will be present over most of
the CONUS today, but with several small areas of some concern for
thunderstorms. These include the Pacific Northwest, Northern
Plains, Mid/Upper MS Valley, and FL.
...Florida...
A weak surface front lies across the central FL peninsula, with
strong heating and dewpoints in the 60s leading to moderate
afternoon CAPE. Similar to yesterday, scattered thunderstorms are
expected along the east-coast sea-breeze and along/south of the
front. Winds aloft are weak, but cool temperatures aloft could be
sufficient for a strong storm or two capable of hail or gusty wind.
The overall threat appears too low to warrant severe probabilities
at this time.
...IL/IN...
Visible satellite imagery shows a zone of weak low-level warm
advection over IA, spreading eastward into IL. Several model
solutions suggest the risk of some lightning activity this afternoon
in this region, although it appears to be rooted in the mid-levels
and unlikely to produce any severe risk. After dark, more active
thunderstorms may develop over eastern IL and much of IN, but weak
instability will continue to limit any organized severe threat.
