...Synopsis...
A midlevel shortwave trough is moving over the Lower Great Lakes
now, and subtle veering of flow this afternoon will result in
shorter over-lake fetches and reduced depth/organization to the lake
effect snow bands.  Given the marginal thermodynamic profiles for
charge separation, the threat for isolated lightning flashes is
expected to diminish through the afternoon.  Farther west, a
midlevel low will move slowly eastward toward the central/northern
CA coast by early Wednesday.  There may be sufficient
cooling/moistening of profiles for weak buoyancy and isolated
lightning flashes near the end of the period along the coast.
