0543 PM CDT Sun Jul 16 2017
Areas affected...northern and central Ohio
Concerning...Severe potential...Watch unlikely
Valid 162243Z - 170015Z
Probability of Watch Issuance...5 percent
SUMMARY...A few instances of downburst winds and hail will remain
possible over northern and central Ohio through early evening. Any
severe events are expected to remain too sparse and overall threat
too marginal for a WW issuance.
DISCUSSION...Isolated storms continue developing along a slow-moving
cold front and in association with lake breeze across northern OH.
Atmosphere is moderately unstable with around 1500 J/kg MLCAPE and
6.5 C/km mid-level lapse rates. The storms are embedded within
modest west-northwesterly deep-layer winds with weak effective shear
supportive of multicells. Activity is diurnally driven, and will
pose a modest risk for hail and downbursts winds as cells develop
southeast next few hours. A gradual diminishing trend should occur
by 02Z with onset of nocturnal cooling.
