Can’t rule out a stray lake effect shower, from 407 and parts north this afternoon or evening and perhaps a flurry in those same locations for tonight. Mainly dry conditions are likely for Wednesday morning into the early afternoon. Models are indicating the risk of snow developing Wednesday evening through the overnight into Thursday. Right now snowfall amounts are low confidence due to temperatures and forecast track. However there is at least the risk of this seasons first accumulating snowfall, though road temperatures will remain just above freezing, so any accumulation 1-3cm at most will be on grassy and elevated surfaces.
