According to the National Weather Service in Pittsburgh, PA, residents can anticipate a cool spell with dry conditions. Temperatures are projected to fall below average starting today and extending into tomorrow. Highs may struggle to reach the 70-degree mark, especially for areas south of the city, with a 30-50% probability of hitting that threshold.
The forecast for today indicates a potential for drizzle in regions north of Pittsburgh, where probabilities sit between 5-10%, but the chances remain low. Moving into Monday night, cooler temperatures will continue thanks to a clearing sky and diminished winds near the surface. You might want to grab that extra layer for those out late, as the thermometer dips even further.
However, changes are on the horizon as a low-pressure disturbance is set to introduce precipitation to the area from late Tuesday into Wednesday. "Probability of rain increase late Tuesday into Wednesday as this disturbance advances east, phases with a noted weak low over the Great Lakes, and becomes an open wave," reported the National Weather Service. Rainfall could tally up to an inch, with a 40-50% chance for the southern parts of Pittsburgh and along the ridges, though the probability of a two-inch downpour is below 20%.
Don’t put away those umbrellas just yet, as light rain is slated for Thursday through Friday, albeit without the risk of excessive rainfall. The weather system responsible is expected to push eastward, leaving New England by the end of the week. Meanwhile, cooler-than-usual temperatures persist, marked down by about five degrees from the norm,
For those with eyes to the sky or flight plans, the aviation forecast from the National Weather Service indicates a broken VFR cumulus/stratocu layer should develop by midmorning today. Beware of gusty winds throughout the day, but rest assured, they should wind down as evening falls. "Gusty wind will continue, especially during the daytime, with mixing and a tight pressure gradient." VFR conditions return Monday under high pressure before restrictions and showers potentially disrupt from Tuesday through Thursday alongside the incoming low pressure.
