Watch issuance is not expected. DISCUSSION...Latest GOES imagery and lighting data show the early stages of thunderstorm development across northeast OH into western NY within a diffuse surface trough and along developing lake breeze boundaries. Thunderstorm coverage should slowly increase through the afternoon as temperatures warm and baroclinic circulations strengthen along the lake breeze boundaries. Despite warm/moist low-level conditions, modest mid-level lapse rates should limit overall buoyancy values to around 1000-1500 J/kg. Additionally, deep-layer wind shear over the region remains fairly meager with regional VWPs and morning RAOBs sampling mid/upper-level winds of around 20-30 knots. Given weak low-level flow, this will be adequate for some degree of storm organization and persistence, but should modulate overall convective intensities. Watch issuance is not expected, but a few instances of damaging winds appear possible as storms develop through the afternoon. ..Moore/Mosier.. 07/10/2025 ...Please see www.spc.noaa.gov for graphic product...
