As the snow tapers off in Pittsburgh, residents are looking ahead to a mix of weather conditions, including a brief dry spell followed by an anticipated weekend system and a dangerously cold arctic outbreak early next week. According to the National Weather Service in Pittsburgh, PA, Friday should remain dry due to high pressure, making a short visit to the area. However, expect changes as the weekend approaches, with rain, a wintry mix, and snow likely on the horizon for Saturday.
With Saturday's incoming system, precipitation could kick off as a mix of rain and snow due to the meddlesome warm air competing with cooler temperatures. Forecasters seem confident that the wintry mix will not include ice, as the NBM probs are giving 0% for ice potential for tonight and Saturday night. Snow probabilities reach 50% in the northern parts for accumulating over an inch by Saturday night.
Looking further out, the weather narrative shifts towards a significantly colder script. Light snow showers may persist into Sunday and Monday under a northwest flow, potentially tempered by Lake Erie's surface state as it approaches full ice coverage. Nevertheless, attention is increasingly cornered by the pending Arctic outbreak, which is forecasted to blast the region with extreme temperatures Monday through Wednesday. The mercury may well stage audacious escapes from the norms of seasonal warmth.
The anticipated deep freeze is set to pose serious challenges with extremely low temperatures and wind chill temperatures. Expressing high confidence in the severity of the cold snap, the Weather Service warns of routine hazards such as inclement conditions, such as frozen pipes, hypothermia, and frostbite times that are severely truncated to mere minutes. As if aware of their vulnerable flesh, the forecast implies a stern advisory for prep time – now. Events, especially those rooted outside, are urged to renegotiate dates with more hospitable climes.
In aviation, recent light snow and flurries have largely dissipated, paving the way for an uptick in visibility. At the same time, ceilings persist in a dogged cling to the lower margins of MVFR conditions. A measurable improvement to VFR throughout the day follows drier air ushered in by the building ridge. Meanwhile, pilots are briefed to watch for a mixed bag of conditions, as another system on Saturday could bring restrictions and rain/snow back to the area over the weekend.
