From the shade of his golf cart, Al Flick watched the final teams left in the 57th annual Grandview Four-Ball tournament on Sunday.

The weather was beautiful: low humidity, 75 degrees and not so hot that it sucked moisture out of the greens, he said.

For Flick, golf season kicked off about four weeks ago — but conditions haven't been as nice as Sunday's, he said.

Ice and snow from the winter left damage on golf course greens that is just beginning to heal at the start of June, said Flick, 60, of Boiling Springs.

And that's been the case from Florida to the Carolinas, he said.

"It's all the way up the East Coast," Flick said.

Even May's weather wasn't up to par, said golfer Brad Miles, 25, of Dillsburg.

"It was colder than usual, windy, kind of wet, too," he said. "Just not typical, I guess."

But golfers shouldn't get too used to poor weather: June is here, and one long-range forecaster predicts a warm summer.

Weather woes: Grandview Golf Club has felt the chill so far this year, said Joshua Grundon, director of golf at the Dover Township club.

Last year, it opened for business in January; this year, snow delayed its opening till the middle of March, he said.

And the weather's also been wet: A little over a month ago, rains caused the nearby Conewago Creek to flood the course, Grundon said.

"It's definitely been a much rainier year this year than in years past," he said.

After Dover's dry-township status was lifted in 2011, Grandview obtained a liquor license, and the club opened up a bar this year, Grundon said.

The bar is open to the public and is an effort to stimulate a part of the club's business that isn't reliant on weather, he said.

Recap: In York, May was drier and slightly cooler than usual this year, said Rich Jaworski, a meteorologist with AccuWeather.com.

Data from York Airport in Thomasville show that this year's average May temperature — the mean of the month's high and low temps — was 61.5 degrees, 0.9 degrees below normal, he said.

May's normal rainfall is 4.19 inches, and this past May saw only 2.58 inches — about 62 percent of normal rainfall, he said.

For the year through May 31, temperatures are well below normal, Jaworski said. The average temperature so far is 39 degrees — 5.7 degrees below normal, he said.

"Really, we should be in the mid-40s," Jaworski said. "That just goes to show how cool it's been."

The weather has also been wetter overall, with 20.54 inches of precipitation through May, compared to a normal figure of 17.25 inches, he said.

"So to this date in the year, we're actually slightly above normal — about 119 percent of normal," Jaworski said.

Ahead this week: This week, York will see a chance of thunderstorms pretty much every day, said Elyse Colbert, a meteorologist with the National Weather Service.

"It's going to be warm, but unsettled," she said.

Monday will be sunny, with a high near 79 and a low around 61, the forecast says. Then the chance of thunderstorms begins.

"There's going to be a lot of little disturbances moving through," Colbert said.

Scattered showers and thunderstorms are in the forecast from Tuesday through Friday, with Tuesday and Wednesday having more "all-day" types of rain events, she said.

The week will see highs in the low to mid-80s and lows in the mid-60s, Colbert said.

Summer forecast: Looking ahead to this summer, weather patterns will vary for York, said Erik Pindrock a meteorologist and member of AccuWeather's long-range forecasting team.

In June, average temperatures will likely be within two degrees above or below the normal 71.3-degree mark, he said. Rainfall totals should also be near the monthly average of 3.62 inches, Pindrock said.

July's average temp should also be within two degrees of the normal 75.2 degrees, he said. But Pindrock is forecasting a little above the normal 4.1 inches of rainfall in July — anywhere from 120 to 140 percent of that figure.

For August, temperatures will be 2 and 4 degrees above the average temperature of 73.6, Pindrock said. The month's precipitation will be slightly below average: about 60 to 80 percent of the usual 3.43 inches, he said.
