For overnight
Mesoscale Discussion 0321
NWS Storm Prediction Center Norman OK
1150 PM CDT Wed Apr 08 2020
Areas affected...West Virginia into western Virginia
Concerning...Severe potential...Watch possible
Valid 090450Z - 090645Z
Probability of Watch Issuance...40 percent
SUMMARY...A line of severe storms may still be severe as it
approaches the eastern parts of Tornado Watch 93.
DISCUSSION...A strongly forced line of storms with history of
damaging winds continues rapidly eastward at over 50 kt. VWPs ahead
of the line indicate modest southwesterly winds just off the
surface, which is helping to increase moisture and instability
values to the east, and despite relatively cooler surface
temperatures. Despite marginal instability, the high level of
organization suggests some chance of continued severe wind threat as
the line approaches eastern WV and possibly across the VA border.
Trends will continue to be monitored, and another watch may need to
be considered.
