Chris Rosier has a cool plan for working in the summer's heat.

"I take a lot more breaks and take in plenty of water and fluids, like the ones with electrolytes," said Rosier, who owns Dover Mower with his wife, Shauna Rosier. "Don't go fast, don't go hard, just pace yourself. You don't want to put stress on yourself in the heat."

With summer's start Friday, the temperature is expected to be in the upper 80s throughout the weekend, said Greg DeVoir, senior forecaster with the National Weather Service.

"It's going to feel summer-like, no chances for precipitation Saturday and Sunday," he said. "And you'll have upper 80s on Monday and Tuesday with increasing humidity throughout the weekend and in early next week."

Rosier said he expects to get a lot of lawn care business as the weather gets hotter.

"(Customers) can no longer do outside maintenance because of the excessive heat and they don't want to be bothered with it, so they call us," he said.

Darrell Hoover, owner of Alexander's Lawn Care in Dallastown, said he got a lot of customer calls during the spring, as grass grew in the season's cooler-than-normal weather.

"People also wanted planting done," Hoover said. "Summer is not a good time for new planting or new growth, so you do it earlier. The spring treated us pretty well."

Spring this year was cooler than last year and drier than 2011, said Jack Boston, expert senior meteorologist with AccuWeather.com.

In March this year, the average high temperature was 49.3 degrees, while the normal temperature is 54, he said. There were 2.39 inches of precipitation. The normal amount is 3.68, according to Boston.

April's high temperature was 1.4 degrees lower than the normal high of 66 degrees. However, there were close to 1.5 inches of rain, compared to April's norm of 3.5 inches.

For May, the average high temperature was near 74, two degrees lower than the month's normal high temperature. There were 2.77 inches in rainfall, compared to the normal 4.19 inches, Boston said.

For the first 20 days of June, the high temperature was about one degree cooler than the normal high of 83, he said. However, with 4.3 inches of rainfall, the month was wetter than the norm of 2.39 inches, he said.

"Good news," Boston said. "We're not expecting any rain this weekend, with exception of maybe a thunderstorm here or there on Sunday afternoon, but it should be mainly dry."
