If you expected Memorial Day weekend to bring backyard cookouts, poolside afternoons and summerlike heat, think again.

After Pittsburgh came within striking distance of a record high Monday, the National Weather Service says the holiday weekend forecast is shaping up to look much different, with cooler temperatures and the potential for thunderstorms.

“It’s going to be a little damp,” said Shannon Hefferan, a meteorologist at the National Weather Service in Moon.

Friday’s forecast calls for a chance of rain after 2 p.m. The weather will be mostly cloudy, with a high near 69 degrees. Friday night, more rain is likely, with the possibility of thunderstorms after 2 a.m. and lows around 52 degrees.

Rain and possible thunderstorms are also predicted for Saturday. Temperatures are forecast to reach a high near 66 degrees during the day before dropping to around 57 overnight.

During the week, the National Weather Service posted multiple reminders for the public about thunderstorm and lightning safety.

“A lot of us will be outdoors a lot this Memorial Day weekend, so remember: Thunderstorms can produce deadly lightning strikes up to 10 miles away,” the post said.

“Lightning strikes can result in death or serious injury. If you hear thunder or see lightning, take shelter in an enclosed building or a hard-topped vehicle with the windows rolled up,” another post said.

Hefferan said that while Sunday temperatures are expected to warm to the low 80s, showers and thunderstorms are possible after 2 p.m. Lows will be around 63 degrees.

Temperatures are also expected to reach the low 80s on Monday before dropping to around 62 in the evening.

Hefferan said the Pittsburgh area will not see particularly high winds nor is the weather service forecasting any severe storms.
