Key Points

Pittsburgh is only 1.66 inches short of its annual average rainfall total of 39.61 inches, and through Sept. 20 it was on pace for the city’s fifth-fastest year for precipitation.
2
In the Pittsburgh area, the greatest flood threat is expected during the morning hours, while afternoon showers and drizzle are forecast to have rain rates too low to cause significant additional flooding; Tuesday could bring heavier rain from roughly midnight to 5 a.m.
3
A stationary front south of Pennsylvania is expected to keep shower chances in the region through Thursday, with forecast highs ranging from near 60 to the low 60s on Tuesday through Thursday in parts of eastern Pennsylvania.
4
The Philadelphia region could see an early-afternoon break in the rain before showers return, while heavier pockets and thunderstorms are possible near Delaware and South Jersey Sunday night; most of that rain is expected to clear by midnight.
5
The National Weather Service attributed the incoming rain to a fast-moving low-pressure system traveling east from the central states across Pennsylvania, while high pressure building south from Quebec could make Monday the week’s most favorable day for outdoor activities.
Rain and thunderstorms will drench Pennsylvania this week, with the heaviest downpours expected overnight and through Tuesday morning, according to NBC Philadelphia. Pittsburgh is especially vulnerable to flooding — the city has already received 37.95 inches of rain this year and needs just 1.66 more inches to match its annual average of 39.61 inches, NBC Philadelphia reports. Scattered showers will continue through Thursday as cooler air keeps temperatures stuck in the 60s.
Pittsburgh Bracing for Flood Risk From Relentless Rain
Pittsburgh is on pace for its fifth-wettest year on record, according to NBC Philadelphia. The city's morning hours pose the greatest flood danger as heavy rain develops. Afternoon showers will bring lighter rain that poses less flooding concern. But by Tuesday, between midnight and 5 a.m., heavier rain could return and renew flood threats in low-lying areas.
A Stationary Front Keeps Rain In The Forecast Through Thursday
A stationary front camping south of Pennsylvania will fuel repeated showers and possible thunderstorms through Thursday, NBC Philadelphia reports. Temperatures will lag behind normal, with highs in eastern Pennsylvania staying near 60 to the low 60s. A fast-moving low-pressure system traveling east from central states will deliver much of the rain. Philadelphia may get a brief dry break in the early afternoon before showers return later.
Drying Trend and Warmer Weather Return by Weekend
High pressure building south from Quebec will make Monday the best day this week for outdoor plans, NBC Philadelphia reports. The region will gradually dry out from Wednesday onward as the stationary front weakens. Warmer, sunnier conditions are expected next weekend, offering a welcome reprieve from the wet, cool stretch. Temperatures should climb closer to normal as drier air pushes in.
