Looks like a severe thunderstorm watch will be coming soon. Guess we'll have to see if we actually get anything severe with a watch this time, or if the streak of having more severe weather around here without a watch continues.
Mesoscale Discussion 0909
NWS Storm Prediction Center Norman OK
1107 AM CDT Fri May 31 2019
Areas affected...western portions of VA/NC and the VA/NC Piedmont
Concerning...Severe potential...Severe Thunderstorm Watch likely
Valid 311607Z - 311800Z
Probability of Watch Issuance...80 percent
SUMMARY...Isolated to widely scattered thunderstorm development is
forecast over the next 1-2 hours (12pm-2pm EDT) near the higher
terrain over western NC and western/southwestern VA. Isolated
storms may also develop over the Piedmont by 2pm EDT.
DISCUSSION...Late morning water vapor imagery loop shows a mid-level
shortwave trough over KY/TN and this feature is forecast to reach
the southern Appalachians by mid afternoon. Visible satellite
imagery shows a swelling cumulus field over the southern
Appalachians immediately east of the eastward-migrating disturbance.
Surface observations indicate temperatures have warmed to near 80
degrees F near the mountains and into the middle 80s over the NC
Piedmont. Low-level moisture increases from west to east across NC
with surface dewpoints near 60 degrees F in the west, low-middle 60s
over the Piedmont, and upper 60s to near 70 in the coastal plain.
Reflective of the low-level moisture field, buoyancy is forecast to
be highest near and east of I-95 with 2000-2500 J/kg MLCAPE expected
by late afternoon with steep 0-3km lapse rates. Strong heating will
contribute to 1500-2000 J/kg MLCAPE farther west near the I-77
corridor by early afternoon. A belt of 30-35kt westerly 500mb flow
will act to organize updrafts this afternoon beneath 60-80kt
upper-level westerly flow. Despite weak low-level flow, elongated
hodographs will favor the potential for splitting supercells and
severe multicells capable of large hail and severe gusts (60mph).
The propensity for wind damage will likely increase coincident with
richer low-level moisture as storms move/grow upscale from
west-central into east-central portions of NC later this afternoon
into the early evening.
