Day 1 Convective Outlook 
NWS Storm Prediction Center Norman OK
1129 AM CDT Tue Apr 26 2022

Valid 261630Z - 271200Z

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS SOUTHEAST
VIRGINIA...

...SUMMARY...
Sporadic damaging winds from locally strong gusts and small to
marginally severe hail will be possible this afternoon across
southern/eastern Virginia and parts of the Carolinas and eastern
Georgia.

...Southeast Virginia and Carolinas/eastern Georgia...
Ample insolation is occurring across the region in Piedmont/coastal
areas and east of the Blue Ridge with an expanding/deepening cumulus
field coincident with temperatures reaching 80F in many locations by
late morning. A late-morning increase in thunderstorms has already
been noted near the eastward-advancing front, which largely
parallels the mountains/Blue ridge at midday.

As storms further develop/intensify, a well-mixed boundary layer
with steep low-level lapse rates in conjunction with moderately
strong southwesterly mid-level winds will support some stronger
multicells capable of isolated wind damage and possibly some hail
through late afternoon/early evening. That said, it appears that a
more focused potential for wind damage/some hail will exist across
southeast Virginia this afternoon. This will be in vicinity of a
weak surface wave and the remnant wedge front/effective warm front.
This corridor will also be under the influence of somewhat stronger
cyclonically influenced low/mid-level flow.
