Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0255 PM CDT Tue Apr 26 2022
Valid 262000Z - 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 remain possible late this afternoon
across southern/eastern Virginia and parts of the Carolinas and
eastern Georgia.
...20Z Update...
The primary changes to the outlook at 20Z are to clear severe
probabilities behind the cold front across parts of the Southeast
and Mid Atlantic, and to restrict the 5% hail area to parts of
southeast VA, where a few stronger discrete cells remain possible.
Damaging wind and localized hail remain possible across southeast VA
through the remainder of the afternoon, with a more isolated
damaging-wind threat extending further southward into the Carolinas.
See WW 155 and the previous outlook discussion below for more
information.

.PREV DISCUSSION... /ISSUED 1129 AM CDT Tue Apr 26 2022/
...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.
