Warm weather lovers in Pittsburgh can rejoice for another day of summer-like temperatures before the fall chill settles in. The National Weather Service Pittsburgh, PA, predicts highs in the upper 70s to the lower 80s today, flirting with record highs set over a century ago.
Today's weather is buoyed by a high-pressure system stretching across the Southeastern United States to the Upper Ohio Valley and Lower Great Lakes. According to the morning soundings, it is forecasted to peak at 588 to 591 dams. This dry and warm weather continues with record or near record highs in some locations, as the expanding mercury columns in our thermometers testify. These conditions embody the changing climate patterns with which we are all becoming ever more familiar.
However, the heat wave is set to break by Thursday evening as a cold front approaches, bringing with it the return of showers and a sharp departure from the near-record-setting temperatures. Showers are expected to overspread the region from W-E late Thursday and Thursday night with the approach and passage of the front, forecasting light rainfall amounts.
Looking to the skies for the weekend shows promise for clear conditions and light winds for the Pittsburgh area. According to aviation forecasts, ensembles favor high-pressure redeveloping over the region by Friday afternoon through the weekend to promote VFR and light wind conditions. For weather buffs and laypersons alike, this signals smooth flying and serene autumn days ahead.
And for the record chasers, Wednesday could bring record-tying warmth to Pittsburgh and surrounding locales. "A few locations could approach, or break, record high temperatures through Thursday," the National Weather Service indicates.
