Pittsburgh is expecting a bit of a weather seesaw this week, with temps set to climb before diving back into the chilly depths, accompanied by some winter precipitation. According to the National Weather Service Pittsburgh PA, dry conditions and a warming trend in temperatures are expected over the next couple of days, with widespread rain returning late Thursday before changing over to snow Friday morning.
This Tuesday morning kicked off with a bite, as frosty single digits and low teens took hold under clear skies. As the day progresses, sunshine should nudge temperatures upward yet remain well below normal for this time of year. Tonight through Wednesday night, we're looking at continued dry weather and a warming trend. The high pressure making this possible will scoot eastward, making way for low pressure from the Great Lakes later in the week.
Thursday promises to be the warmest day Pittsburgh's felt in some time, with highs hovering 10 degrees above the norm. An upper trough deepening over the midwestern states will amp up southwesterly flow and warm advection, reports the National Weather Service. But don't get too comfy in your autumn jacket – Friday will see a quick cold shot, taking us straight back to winter.
For those looking skyward, aviation forecasts expect VFR with dry weather through the majority of the TAF period. There's some uncertainty after 21z with a potential 40-60% probability of sub-3kft ceilings. Come the weekend, another low-pressure wave could spell rain for the region, particularly north of Pittsburgh, and the start of next week looks to reset back to dry conditions with high pressure taking charge again.
