A moisture-laden Texas low is setting its sights on Southern Ontario.

The disturbance expected to affect Southern Ontario is currently approaching Ohio and will intensify and track across Lake Ontario Tuesday morning. Rain is now spreading across southern portions of the province and is expected to reach Georgian Bay this evening.

A significant general rainfall of 15 to 25 mm is likely over much of Southern and Eastern Ontario with the higher amounts likely closer to lakes Erie and Ontario. Rainfall warnings have been issued northeast of lakes Erie and Ontario where 25 to locally 35 mm of rain are forecast.

The rain will likely change to a heavy wet snow late this evening mainly over the higher terrain of the Dundalk and Haliburton Highlands. A significant accumulation of 5 to 10 centimetres appears likely in these areas before it tapers off early Tuesday. Locally higher amounts are possible, especially over the Bancroft through Algonquin Park areas. Snowfall warnings seem unlikely as it appears amounts will probably remain below the warning threshold of 15 centimetres.

On a more spring-like note, the warmest weather of the season is likely to begin on Thursday to the south of Georgian Bay, quickly erasing any memory of the snow on Monday night. Temperatures are expected to climb well into the teens, but will likely be more muted east of Georgian Bay.
