Isaias Remnants Bring Rain to Pittsburgh This Weekend
8 Oct
Summary
- Hurricane Isaias remnants will bring widespread rain to Pittsburgh.
- Rainfall is expected over a 24-hour period, with low flood risk.
- Temperatures will rise into the low to mid-70s next week.
The U.S. Gulf Coast is experiencing Hurricane Isaias, with its remnants now forecast to impact the Pittsburgh area this weekend. Although the risk of significant flooding for western Pennsylvania is low, widespread rain is expected over approximately 24 hours. The initial signs of Isaias's influence will appear Friday afternoon as outer clouds move in.
Saturday will remain dry, but skies will become increasingly cloudy. Southeast winds will drive warmer air into the region, pushing high temperatures into the low to mid-70s. By Sunday, the storm system will merge with an upper-level low, becoming non-tropical as it enters the Ohio Valley, leading to rain starting mid-morning Sunday and lasting through Monday morning.
Most weather models predict 0.75 to 1.25 inches of rain for the Pittsburgh area, with a less likely scenario reaching 2 inches. The extended rainfall period and absence of thunderstorms should prevent excessive rainfall rates. Following the system's departure on Monday, gradual clearing will occur.
Warm air will surge into the region on Tuesday, potentially bringing showers and thunderstorms as temperatures reach the low to mid-70s again. A brief cool-down is expected Wednesday before warmer weather returns by late next week.
