As Pittsburgh wakes up to pockets of dense fog this morning, residents should anticipate clearer skies later today. According to the National Weather Service in Pittsburgh, the early fog, which has significantly impacted visibility, especially along the southeast of a Wheeling-Pittsburgh-DuBois line, is expected to dissipate post-sunrise. Thanks to the proficient work of night-time microphysics satellite imagery, this foggy predicament has been well-documented – so much so that a dense fog advisory is in place until 9 AM EDT.
Moving into tonight, high pressure is set to maintain tranquility in the weather department. However, the peace won't last long as a shortwave trough from the northwest is projected to bring back showers and potentially severe storms, particularly north of Pittsburgh. "Scattered showers and thunderstorms are expected to develop through the day as the shortwave approaches," the NWS Pittsburgh discussion states. By the afternoon, some storms could become organized and intense, although the NAM model appears more bullish on this potent storm potential than other models or the machine learning data.
For those flying, the aviation outlook underscores clearing conditions post-12z with some lingering MVFR at higher terrains. "A series of shortwaves within the NW flow will create periodic storm chances Monday (primarily the I-80 corridor) through Wednesday (more widespread by then)," which suggests travelers should keep a keen eye on the skies as well as the flight statuses, as reported by the National Weather Service.
