Just as Western Pennsylvania started settling into mild spring weather, a sudden weather twist is on the way. Starting Tuesday night, residents in Pittsburgh, Latrobe, and nearby areas could face a quick blast of rain and a sharp 10-degree temperature drop. So, if you were thinking about a warm evening stroll or late-night errands—you might want to think again.
From Mild to Moist: Here’s What’s Happening
The region has enjoyed a few pleasant days, but that’s about to change fast. Weather experts say a cold front is heading toward Western Pennsylvania, bringing in cloudy skies, widespread rain showers, and a noticeable chill in the air by Tuesday evening.
Forecasts show:
-
Afternoon temperatures in the upper 60s to low 70s during the day
-
Evening temps dropping quickly into the upper 50s and lower 50s
-
Rain starting by late afternoon or early evening and continuing overnight
The weather change is not dangerous, but it could catch people off guard if they’re not prepared.
What Pittsburgh & Latrobe Can Expect
In Pittsburgh, Tuesday is expected to start off fairly dry and comfortable. But don’t let that fool you—showers are expected to move in quickly after 4 PM, with steady rainfall likely during the evening hours. As the front passes, temps will slide from the 60s to the 50s, making the air feel noticeably cooler—especially with the dampness from the rain.
Latrobe will see similar conditions. The evening commute could get messy with slippery roads and reduced visibility due to light rain and cloudy skies. By night, you’ll definitely want a hoodie or light jacket if you’re out and about.
Driving or Heading Outside? Be Ready
Tuesday night could be inconvenient for commuters and anyone planning outdoor events. Here’s why:
-
Roads may become slick, especially in areas with poor drainage
-
Fog and light drizzle may reduce visibility late at night and early Wednesday
-
Morning travel on Wednesday could be slower due to damp roadways and lingering fog
So, if you have early plans, set your alarm a bit earlier and check weather updates before heading out.
What’s Causing This Change?
This shift in weather is thanks to a cold front sweeping east from the Midwest. As it moves through Western Pennsylvania, it pulls in cooler air from the north and forces out the warmer, stable air that’s been sitting over the region. These kinds of fronts are common in the spring but can still catch people off guard—especially when they hit fast and at night.
This one isn’t strong enough to bring thunderstorms, but it’s enough to shake up your plans and remind everyone that spring still has its cold snaps.
How Long Will It Last?
The cooler temperatures are expected to stick around through Wednesday, but by Thursday and Friday, things should start warming up again. Rain will likely move out by early Wednesday morning, giving way to clearer skies later in the day.
So, the good news is: this chilly, rainy spell will be short-lived, but it’s still a good idea to plan ahead.
