1236 PM CDT Sun May 27 2018

Areas affected...Much of central into eastern Wyoming

Concerning...Severe potential...Watch likely

Valid 271736Z - 272000Z

Probability of Watch Issuance...80 percent

SUMMARY...Storms should increase in coverage and intensity through
the afternoon, with damaging wind and/or hail possible.

DISCUSSION...A moist air mass has spread into central WY due to east
and northeast surface winds, resulting in an unstable air mass.
Heating will persist as well, with MUCAPE in excess of 2000 J/kg
into eastern WY where moisture is most substantial. Meanwhile, lapse
rates are steep through a deep layer courtesy of the upper trough.
Although mid and upper flow is not strong, these southerlies atop
low-level northeasterlies is elongating hodographs and will be
supportive of organized storms over the entire region. Storms are
already forming near the Wind River mountains due to upslope flow,
and these storms will gradually expand southeastward toward a
developing CU field near the south central mountains of WY. Damaging
winds will be possible given the expected elongated/somewhat linear
storm mode, but embedded cells, and/or any isolated cells that may
form will be capable of large hail given the cold air aloft.

Areas affected...southeast Virginia/northeast North Carolina

Concerning...Severe potential...Watch unlikely

Valid 051833Z - 052030Z

Probability of Watch Issuance...20 percent

SUMMARY...Limited/local severe risk may evolve this afternoon across
portions of the discussion area -- mainly in the form of gusty
winds. A watch is not anticipated.

DISCUSSION...Latest surface and objective analyses across the
southeastern Virginia/northeastern North Carolina region indicate a moist/modestly unstable environment, with overall degree of CAPE
limited due to a combination of heating being tempered by broken
cloud cover, along with weak lapse rates aloft.

Ahead of the eastward-moving surface cold front -- trailing
southward from a weak northern Virginia surface low -- showers have
been on the increase over the past 1-2 hours. As heating maximizes,
a few thunderstorms are expected to evolve.

While modest CAPE should temper coverage/intensity of convection,
moderately strong west-southwest flow aloft remains across the area.
This will support fairly rapid cell motion, as well as bulk shear
sufficient for storm organization. Particularly if convection
manages to grow upscale locally, into short bands, risk for
gusty/locally damaging winds could accompany the convection.
Overall, the degree and coverage of risk should however mitigate the
need for WW issuance.
