As Pittsburgh basks under the influence of high pressure from the northern Great Lakes, forecasted a stretch of dry weather extending through the coming weekend. In a report by the National Weather Service in Pittsburgh, published this morning, meteorologists predict seasonably cool temperatures culminating in a moderate climb toward normal by the weekend and into next week. For those yearning for a respite from any summer swelter, this forecast might be seen as a brief sigh of relief.
Wednesday's outlook, outlined by the National Weather Service, called for "Mainly clear skies under high pressure," which will set the stage for temperatures to dip below seasonal norms. The crisp air is not without its geographical nuances – those settled in the urban cores might not feel the chill as deeply as their suburban neighbors. As high pressure continues its southeast journey today, northerly winds will keep the mercury reading restrained, with areas northeast of Pittsburgh having slim chances – "a 0% to 20% chance of warming above 70 degrees".
Moving toward the weekend, the weather's storyline remains staunchly undramatic. The aforementioned high-pressure system is expected to slide southeast and set up over the Upper Ohio Valley by Thursday and Friday, the Weather Service added, cinching an end to the cooler air's intrusion. Thursday will likely persist with below-normal temperatures; however, forecasters anticipate a return to standard warmth by Friday. As the upper ridge shifts eastward, the region is set to once again acquaint itself with the routine August heat.
Aviation forecasts, another key component, echo the ground-level tranquility with High confidence in VFR and light wind as high pressure dominates the weather regime into next weekend. Flight paths over Pittsburgh should experience minimal meteorological turbulence, with early morning river valley fog the only mild impediment, which is expected to clear rapidly after sunrise.
