Weather Outlook for July 1, 2014

Tags:

Posted: July 1, 2014

A mix of humid, humid weather days and cooler, drier weather is expected in the upcoming forecast.

As June ended, rainfall across the state had tallied at or above normal levels in all but about a dozen counties, mainly concentrated over the northern Poconos. The wettest region was on the western side of the Allegheny Plateau where upwards of 10 inches fell in parts of Jefferson and Clarion counties. Temperatures averaged slightly above seasonal levels, between 0.5 and 1.5°F, though a few pockets in the northern tier were very close to the long-term average. There are very few signs of stress on any crops in Pennsylvania. The week ahead will begin with two cold fronts crossing the Commonwealth accompanied by a scattered to broken line of thunderstorms, mainly in the western half on Wednesday and the eastern half on Thursday. The developing Tropical Storm Arthur near Florida's east coast will be drawn northward ahead of the cold fronts. The main effect in Pennsylvania of the storm's expected offshore track is to delay the cold front causing clouds to linger across the eastern counties into Friday with showers possible in the lower Delaware Valley. Cool and much drier weather will ensue for later on Independence Day with chilly readings (perhaps even a few 30's) in the northern tier at daybreak on Saturday. The air mass will steadily moderate during the weekend as a surge of hot, humid air is expected for the first half of the next work week. Clouds will return late Sunday in the west and a few thundershowers are possible on Monday in the northern tier as very humid air arrives. Tuesday will likely be the peak of a 3 day heat spell as another cool front will arrive with more thundershowers on Wednesday. There is a chance that this front will stall just south of the state later next week keeping clouds and showers nearby.
