Today, Pittsburgh can breathe a sigh of relief from extreme weather conditions as the National Weather Service predicts relatively quiet weather with temperatures expected to warm to near normal, as reported in an early morning briefing. According to the National Weather Service in Pittsburgh, PA, the low pressure tracking across West Virginia may usher in showers for the region starting Friday, particularly from the Pittsburgh area southward.
Despite the calming weather narrative for today, a dynamic atmospheric performance is set to unfold tomorrow. The National Weather Service notes that low pressure should deepen as it moves across eastern Kentucky and West Virginia in the morning and heads for the Chesapeake Bay in the evening. This deepening low could lead to an impressive drop of about 20 millibars in 24 hours, a notable event for late May. Forecasters are confident in predicting a swath of rain producing 0.25-0.50 inches, potentially causing excessive rainfall in some southern counties after recent heavy rains.
As we head into the weekend, Pittsburgh residents should brace for a stark change. The NWS warns of cool and blustery weather on Saturday, with temperatures expected to dip roughly 10 degrees below normal. Also, anticipate showers in the morning, with a drier afternoon expected. A modest temperature rebound is projected for Sunday, but it's the lead into next week that promises a significant warming trend. The city is poised to enjoy temperatures approximately 10 degrees above the average by midweek.
Air travel today should unfold without major disruption, as the National Weather Service anticipates VFR (Visual Flight Rules) conditions post-18z following the lifting of morning fog and low clouds. Concerns loom, however, as the next low-pressure system will return rain chances and areawide restrictions Friday, especially east of I-79, according to the forecast discussion. Saturday's shift to Northwest flow could sustain periods of MVFR (Marginal Visual Flight Rules) with intermittent showers before giving way to more favorable travel conditions Saturday night and beyond.
No watches, warnings, or advisories have been issued for Pennsylvania, Ohio, or West Virginia at this time. Residents in those areas can look forward to a tranquil start to their day before gearing up for the impending shift to more unsettled weather as the weekend approaches.
