Exeter weather RADAR shows a few snow squalls coming off Lake Huron to all shorelines from just west of Grand Bend and northward with a broader area of moderate snowfall extending southeast of London. These snow squalls should get more intense today, however, they will become more isolated by this afternoon.
Intense snowfall rates may be possible for several hours this morning before the band shifts north of Grand Bend this afternoon. Travel could be dangerous due to low visibilities.
Snow squalls cause weather conditions to vary considerably; changes from clear skies to heavy snow within just a few kilometres are common. Visibility will be suddenly reduced to near zero at times in heavy snow and blowing snow. Travel is expected to be hazardous due to reduced visibility in some locations. Road closures are possible.
