Day 3 Convective Outlook

1253 PM CST Tue Feb 25 2025

Valid 271200Z - 281200Z

....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Isolated to scattered thunderstorms are possible across parts of the
southern Appalachians, Carolinas, and southern Virginia on Thursday.
 A few thunderstorms will also be possible across parts of northern
California.

....Discussion...
An amplifying mid-level trough will continue to sweep eastward
across the eastern U.S. on Thursday.  Cold air/steep lapse rates
aloft accompanying the system may support sufficient instability to
permit isolated convective development -- and possibly a few
lightning flashes.  Greater potential for convection -- and
associated lightning chances -- will remain offshore over the Gulf
Stream.

Meanwhile, a mid-/upper-level low will move eastward into northern
and central California overnight.  Cold mid-level temperatures/steep
lapse rates may be sufficient to support sporadic lightning, from
within the broader area of convective precipitation.

Elsewhere, thunderstorms are not expected.
