Environment Canada has issued a snow squall warning for London and the surrounding region.
The snow squall warning was issued early Sunday morning, covering London, along with Eastern and Western Middlesex counties.
According to the weather agency, snow squalls have developed over Lake Huron and are extending inland over parts of Southwestern Ontario. Strong northwest winds with gusts up to 80 km/hr will accompany the snow squalls. Under the snow squall bands, visibilities will be significantly reduced due to the heavy snow combined with blowing snow, and snow will quickly accumulate.
Local snowfall amounts of up to 20 cm within 12 hours are possible in heaviest snow squalls today.
The weather service anticaptes highest amounts of 20 cm, but there is a chance that a strong snow squall off Lake Huron may become nearly stationary across the region today and tonight. If this happens, local snowfall amounts in excess of 30 cm are possible by Monday morning.
