Rain relief finally on the way for drought-stricken Ontario

Some much-needed precipitation is on the way later this weekend

Some much-needed rain is on the way to Ontario to round out this weekend as a low-pressure system moves across the Great Lakes.

Expect the rain to build through the latter half of Sunday, and plan for a wet morning commute to kick off your Monday.

DON’T MISS: More dangerous than snow: Why driving in the rain can be a bigger hazard

We’ve seen a very dry stretch of weather across most of southern and central Ontario. Many communities were mired in a moderate drought or worse as of the end of August, with conditions only worsening through the first few weeks of September.

A little bit of relief is (finally!) on the way.

Ontario precipitation Monday morning

During the day Sunday, we’ll watch a low-pressure system cross the border into the Great Lakes region.

Rainfall chances will begin Sunday afternoon throughout northeastern Ontario, spilling into southern Ontario by Sunday evening.

Folks throughout the Greater Toronto Area can expect a wet Monday morning commute. Locally heavy rainfall and some embedded rumbles of thunder are possible as enhanced atmospheric moisture and some instability move into the region.

Ontario rainfall forecast

We’re not looking at blockbuster rainfall totals, but anything is a step in the right direction. General totals on the order of 10-30 mm are in the forecast, with the highest totals in the southwest toward Windsor and London.

How bad is the rainfall deficit? Toronto-Pearson has only recorded 19.3 mm of rain so far this month, a far cry from the airport’s average September rainfall of 69.4 mm.
