Weather could reach severe levels come Friday morning as a large system being fueled by moisture from the gulf of Mexico rides up a sharp cold front that will slice through the province starting overnight Thursday. Environment Canada has already issued a rainfall warning for the city and area. Behind the front is a pocket of much colder air. It’s that mix of cold air slamming into moist humid air that will leave us wet and then much colder once the front passes. Strong winds could also be associated with the passage of the front.
Rainfall warning in effect for:
Agawa – Lake Superior Park
Sault Ste. Marie – St. Joseph Island
Searchmont – Montreal River Harbour – Batchawana Bay
A low pressure area originating from Texas will cross Missouri this evening and will strengthen as it approaches the Great Lakes overnight. Although some rain has been affecting areas near Lakes Huron and Superior today, more organized heavier rain associated with this system will begin later this evening or overnigh. Current indications suggest this developing system will deliver in excess of 50 mm in the warned regions by late Friday, with some localized areas receiving up to 75 mm. The heavier rain is expected to taper off Friday evening.
Localized flooding in low-lying areas is possible.
Rainfall Warnings are issued when significant rainfall is expected.
