When high school practices start this week, the unusually cool August weather will be at least one respite from the sore muscles that accompany two-a-day practices and shaking off the summer hiatus.

The cooler temperatures continue the streak of not-so-summer weather, caused by an influx of cool Canadian air drifting south farther than normal.

A cold front moving into the York area Monday and lingering for much of the week means that temperatures aren't expected to rise much past 80 degrees, said Paul Walker, senior meteorologist for AccuWeather.

The front, moving in from the west, will bring scattered showers and a possible thunderstorm Monday, Walker said. Thunderstorms and showers are more likely Tuesday as the system moves through the area, with the last of scattered rain on Wednesday, he said.

Monday is expected to be the warmest day of the week with a high of 84 degrees. The rest of the week won't get above 80 degrees, with highs between 77 and 79 degrees.

"That's certainly below normal," Walker said, adding temperatures during this week are often in the mid-80s.

The average high temperature for the month of August is 83.4 degrees, said Kevin Fitzgerald, a meteorologist with the National Weather Service.

Humidity will peak Tuesday, but "things will dry out for the second part of the week," he said.


Summer weather: For people longing for August's normal heat and humidity, Walker said weather models for the rest of the month show the possibility for temperatures more in line with past years.

"It looks like closer to normal for the latter part of August in southcentral Pennsylvania," Walker said. "It will feel warm after these cool days that we're experiencing."

The cool winds from the north are absent during normal summers, Walker said. Any air movement typically comes from the south or southwest, bringing warm, humid air.

Those patterns are likely to start again later in the month, Walker said, increasing the chances for a few last humid days before Labor Day.
