Late Cold Hits North America

March-like cold is gripping much of the North American continent, with an intensification on the cards for many.

Canada

Toronto is seeing daytime hover around 10C (50F), well below the norm of 20C (68F).

The coldest May 22 on record is 9.4C (48.9F), set in 1967. Thursday is unlikely to break that record—but it has a shot.

What does make this event stand out though is it's persistence.

Environment Canada warns the stretch could well delay planting. Garden centers have already reported a sharp drop in activity. “It’s going to remain unsettled,” meteorologist Geoff Coulson said. “Dress for cold, wet conditions.”

U.S.

South of the border, the same upper-level trough is poised to bring March-like conditions to the Mid-South and Lower Midwest.

The NWS is calling for below-average temperatures through the remainder of the month across Arkansas, Tennessee, Oklahoma, and surrounding regions. Little Rock, Nashville, and Oklahoma City are expected to remain stuck in the upper 50s to low 60s (14–17C).

Albany, NY, could make history Thursday with its forecast high of 49F (9.4C). That would make for the lowest-max ever recorded there on May 22. A sub-50 day during May–Sept has only happened twice since 1961, with the average high this time of year being 73F (22.8C).

The chill will remain in place for at least the remainder of the month, particularly for central and eastern states:
