Concerning…Severe potential…Watch unlikely
Valid 051712Z – 051945Z
Probability of Watch Issuance…5 percent
SUMMARY…A few strong storms are possible this afternoon. Isolated
damaging wind is expected to be the primary threat, along with hail
approaching severe limits.
DISCUSSION…A couple of storms have recently developed along a cold
front across northeast OH. Modest heating of a relatively moist
environment will support moderate destabilization (MLCAPE generally
1000-1500 J/kg) along/ahead of the cold front this afternoon. While
stronger ascent associated with a shortwave trough over parts of
Ontario and Quebec will stay north of the region, weakening CINH
will support some increase in storm coverage with time.
With only modest midlevel flow across the region, effective shear is
expected to remain relatively weak (generally 20-25 kt), and storms
will likely struggle to become organized. However, a few stronger
multicells could eventually evolve with time. Locally gusty winds
will be possible with the stronger cells, especially where stronger
heating occurs this afternoon. Also, despite the weak deep-layer
shear, moderate buoyancy and relatively cool temperatures aloft will
support potential for small to near-severe hail.
