MAY OR MARCH?

A lobe of the polar vortex brought air from north of the Arctic Circle into the Northeast and Great Lakes today, colder than what we experienced around Christmastime, just in time for Mother’s Day weekend. (Only in 2020.) The cold air aloft was historic for May 8-9, where temperatures approached -40 degrees near 20,000 feet.

The temperature in Columbus dipped to 30 degrees, tying the daily record set in 1947, 1966 and 1983. Readings in Dublin, Hilliard and Marion reached 28, Lancaster and London 27, and Toledo 26 degrees.

Temperatures this afternoon struggled to approach 50, more than 20 degrees below normal. Cold air aloft brought puffy clouds that will dissipate. However, clouds will arrive from the west tonight ahead of a storm dropping southeast from the northern Plains, so widespread frost is not anticipated, except in eastern Ohio where a freeze warning is in effect early Sunday.

On Mother’s Day, an Alberta clipper, of all things, will introduce scattered showers and isolated storms, with a gusty wind potential and small hail. Chilly showers will linger Monday morning, possibly mixing with a few snowflakes, as another shot of cold air follows departing low pressure.

High pressure over Kentucky will bring fair skies Tuesday and another frost, before temperatures return to seasonal levels as the wind turns southerly midweek. We will likely finally see 70 degrees late in the week, with showers and storms.

Tonight: Some clouds, not as cold. Low 40, frost eastern Ohio
Sunday: Mostly cloudy, milder, showers, gusty storm p.m. High 57
Monday: Mostly cloudy, chilly, passing shower. High 47 (35)
Tuesday: Patchy frost, partly cloudy, cool. High 56 (33)
Wednesday: Mostly sunny. High 62 (38)
Thursday: Mostly cloudy, showers, storms. High 69 (47)
Friday: Showers, storms. High 74 (59)

Have a good weekend and Happy Mother’s Day! -Ben
