Get ready to bring out those umbrellas, Pittsburgh, because the National Weather Service says rain is coming. According to their latest Area Forecast Discussion, today's calm before the storm will give way to a week of showers and possible thunderstorms as a low-pressure system treks across several states before its grand arrival in Ohio on Wednesday.
Today, northerners can bask in a bit of warmth and sunlight before the clouds start rolling in. The official forecast says that clouds are increasing in central and southern areas, but sunshine keeps things warm in the I-80 area to the north. Further south, however, those showers are not shying away. They're expected to pop up by midday and keep temperatures in a more modest mid-70s range.
Tonight through Wednesday night, the forecast is mixed. The forecast warns of locally heavy rain possible this afternoon and tonight over Preston and Tucker Counties, WV, and area-wide Tuesday, especially over the ridges. The potential for thunderstorms will continue through Wednesday with an upsurge in intensity during the afternoon and evening hours, so it might be wise to squeeze outdoor activities in the morning if you’re looking to stay dry.
Later in the week, prepare for a spike in temperatures as the mercury is set to soar 15- 20°F above normal, especially Thursday and Friday. With this heat comes the prospect of strong to severe thunderstorms: Thursday night into Friday has the potential for strong to severe thunderstorms, the advisory cautions. Despite the impending wetness, at least there's a silver lining for sun seekers, with a prediction of a sunnier Thursday on the cards.
Aviation-wise, the skies may start clear, but don’t let that fool you. Pilots and travelers should anticipate disruptions starting this afternoon as showers develop after 18Z for the southern terminals and then move further north, affecting the rest of the terminals by 21Z to 00Z, leading to potential MVFR/IFR conditions. With the weather system inching forward, watch for updates on those arrival and departure boards.
In the overarching view, no severe weather warnings or advisories are currently in place for Pennsylvania, Ohio, or West Virginia, according to the National Weather Service Pittsburgh branch. But with the weather being as fickle as it is, it wouldn't hurt to stay tuned for any changes.
