It’s only the 12th day of September, but already much of southern Pennsylvania has received more than twice the normal rainfall for the month thanks to a battle that was waged between massive high pressure in eastern Canada and tropical moisture from the remnants of Gordon. As both of these depart to the east, weak weather features and easterly winds will lead to a mixture of clouds and sunshine with some showers for the next couple of days while eyes are fixed on hurricane Florence and possible rainfall impacts it may have on Pennsylvania early next week.

A weak disturbance along the east coast will back westward across the state bringing cloudiness and showers Thursday and Friday. High temperatures in the 70s will trend upward to the low 80s for the weekend with mainly fair skies for Saturday and Sunday, though hurricane cirrus clouds will mask the sunshine. By Monday, the remnants of Florence will begin affecting the state with tropical rainfall continuing through Tuesday until a cold front pushes it out, bringing fair and seasonable weather for the middle of next week. Florence rainfall amounts across Pennsylvania could be significant, adding more rainfall to already soggy ground, but will probably not match Gordon since there will be no existing stationary frontal boundary to enhance rainfall amounts. A lighter rainfall event is possible late next week with the passage of another cold front.

Looking farther ahead, the latter half of September is expected to trend below normal in temperature while October is expected to be above normal in temperature with near normal precipitation.
