A warm and mostly sunny day is in the forecast for the 144th Preakness Stakes on Saturday — but there is an outside chance of an isolated shower or storm briefly dampening the festivities.

Temperatures are forecast to approach 80 degrees, with partly to mostly sunny skies. High pressure is forecast over the eastern part of the country, including across Maryland.


But a weak cold front is also forecast to be draped over the region in the lower levels of the atmosphere, and National Weather Service meteorologist Kyle Pallozzi said that means forecasters can’t rule out some scattered showers.

“I don’t anticipate a washout or anything,” he said. “We can’t completely rule out a thunderstorm, as well.”

High pressure normally means clear, sunny skies, and it is expected to discourage widespread precipitation from developing Saturday, Pallozzi said. But some leftovers of a cold front, forecast to move down from the Great Lakes on Friday, are forecast to remain in lower levels of the atmosphere through Saturday, a wrinkle that could produce some spotty showers, he said.

On Friday, meteorologists were predicting chances for isolated thunderstorms would be highest in the evening hours, from around 6 p.m. until sundown. They said isolated showers are possible from the evening through the overnight hours.

But given the expected scattered nature of any precipitation, it was difficult to predict a precise forecast for Pimlico Race Course, or anywhere else in the region, Pallozzi said.

“It’s kind of harder to pinpoint exact timing on things and exactly where things will be,” he said.

Rain and storms are also possible Sunday and Monday.

On Friday, temperatures were climbing amid sunny conditions around the region. The Inner Harbor reached 79 degrees by 1 p.m., while Baltimore/Washington International Thurgood Marshall Airport reached 77 degrees. Scattered thunderstorms are possible Friday afternoon and evening.
