Mesoscale Discussion 0146
NWS Storm Prediction Center Norman OK
0622 AM CST Wed Mar 05 2025
Areas affected...much of central South and North Carolina
Concerning...Severe potential...Watch likely
Valid 051222Z - 051445Z
Probability of Watch Issuance...80 percent
SUMMARY...The environment is beginning to rapidly change, and a ramp
up in severe storm potential is likely. Damaging winds and brief
tornadoes may develop through midday.
DISCUSSION...A strongly forced line of convection continues to push
east across the western Carolinas and southeast GA this morning,
with strong gusts on the order of 40 kt common with this wind shift.
Although bulk CAPE values are currently low, this will likely change
over the next few hours, as low-level moisture streams in from the
south. Local radar indeed shows showers now evident in a north-south
streamer off the ocean.
As the front interacts with the moistening air mass, conditions will
continually become more favorable for rotation within the line, with
brief tornadoes and damaging winds expected. Shear is extremely
strong with 0-1 SRH over 500 m2/s2 over the entire region.
Further, as pockets of heating develop, additional more discrete
supercells may develop, most likely during the afternoon and perhaps
to the east of this early day regime.
