A cold front will move through Cleveland over the next few hours, turning the weather colder and setting up lake effect showers this evening. Northerly winds will follow the front, and the change may affect the Guardians game as temperatures slide into the upper 30s and lower 40s.
That is the part people in Cleveland are searching for today: a quick switch from milder air to a sharper, windier pattern that arrives before nightfall and lingers into the morning. The showers are expected to last through the overnight and into the early morning hours, with some mix possible in the stronger bursts.
The strongest showers should stay tied to the lake effect setup, while high pressure works in behind the front. That combination means dry air will begin filtering in during the early morning hours tomorrow, clouds should hang around through the evening, and sunshine will be ample for much of the evening as the higher pressure settles over the area. Showers are expected to gradually exit around 6 AM.
Even with that clearing, the air mass behind the front will not warm much on Saturday. Northerly winds will keep temperatures in the upper 40s and lower 50s for the entire day, which is cool enough to keep the region feeling more like late fall than midseason. The bigger problem comes after dark, when clear skies and calm conditions Saturday night into Sunday morning allow heat to escape quickly.
That is why another 19 First Alert Weather Day has been put in place for Saturday night into Sunday morning. Overnight lows are expected to drop into the upper 20s and lower 30s over a widespread area, which is the threshold that turns a cold morning into a freeze concern: air at 32 degrees or lower can freeze exposed moisture, and the forecast puts much of the region at or below that line.
There is still one wrinkle in the setup. The same system that brings the showers also leaves room for dry air and high pressure to take over fast, so the strongest rain bands may be brief even as the cold settles in. Some mix is possible in the stronger showers, but the larger story is the quick drop in temperature once the clouds thin and the wind relaxes.
By Sunday afternoon, southerly winds should send temperatures back into the 60s, and that warming trend should hold for much of next week. Even so, Cleveland’s next few hours are defined by the front moving through, the showers trailing behind it, and the freeze risk that follows before dawn Sunday.
