High pressure will dominate the middle part of the week with dry and seasonal temperatures across the state of Pennsylvania. Beginning on Friday, much warmer air and more humid conditions will enter the region in advance of the remnants of Hurricane Isaac. By the end of the day on Saturday, showers and thunderstorms will overspread western portions of the state, with the remainder of Pennsylvania seeing rain by the end of Sunday. Tropical moisture will continue to produce periods of rain across the state through the early part of next week. Isaac’s remnants will be particularly beneficial for western portions of Pennsylvania where the risk for drought still exists. Although difficult to indicate specific parts of the state, some areas will see upwards of a couple inches of rain over the 5-day period from Saturday-Wednesday. Following Isaac, cooler and drier conditions will occur for the remainder of the week.
