The Pittsburgh area is gearing up for a chilly dose of reality as an Arctic cold front moves in, bringing with it light snow and the potential for record-low temperatures tonight. The National Weather Service Pittsburgh PA issued its forecast early this morning, and it's looking like it's time to layer up and tread carefully.
As the front sweeps through the region, residents can expect peak snow accumulation rates of 0.25" an hour or so during the dreaded morning commute. Despite being generally less than an inch, these snow showers could make roads treacherous, with a Special Weather Statement already highlighting potential impacts to road travel. A light taper to spotty freezing drizzle isn't out of the question, and while it isn't expected to be the main event, it's something to watch for, especially given that it's subfreezing temperatures.
Following the snow's curtain call in the afternoon, what awaits is a scene of mostly clear conditions and a biting tale of cold. The National Weather Service foretells temperatures in the upper 20s to lower 30s in the morning and midday, which will dip later, aided by gusty winds. It seems like thermometers are in for a bit of a rollercoaster ride, and Pittsburghers will feel that chill with wind chill values potentially dropping through the teens.
At least four of our climate sites have a chance to challenge record low temperatures for December 5 on Friday morning, the forecast notes. This icy performance is anticipated thanks to a mostly clear sky, diminished wind, and a cozy snowpack to seal the deal. Some areas could see single-digit lows, which would be enough to nudge those decades-old records out of their top spots. The stage is set for a cold act indeed – whether any records will get a standing ovation or just a polite clap, remains to be seen.
As for the traveling types, aviators should keep their eyes peeled for "IFR below cigs expected/vis possible with heavier snow showers, through the morning until the front moves out. According to the forecast, VFR conditions may swoop back in by 06Z tonight, but don't toss those de-icers just yet; more restrictions could pop up over the weekend with a new cold front.
For those looking further ahead, the elongated act of below-normal temperatures promises an encore early next week. A few more snow showers could make a guest appearance from Saturday through Monday. So, whether you're bundling up at home or braving the cold, Pittsburgh is scripting its own winter weather saga, note by frigid note.
