As the golden sun casts a warm glow over Pittsburgh, residents can expect a reprieve from the rain today, with the forecast predicting "quiet weather" under the shield of high pressure, according to the National Weather Service. But don't get too comfortable in that summer breeze, this tranquility is merely the calm before the storm. A warm front is on the horizon, poised to deliver showers and thunderstorms tonight and Saturday.
The weather pivot begins tonight, as Pittsburgh transitions from the day's dry warmth, approximately "5 degrees above normal," to an atmosphere ripe with rain potential, propelled by an "approaching low pressure system." as detailed by National Weather Service. The serene southerly flows will yield increasing moisture, refilling the skies with clouds and chances of rain that had been momentarily chased away.
For those making plans for the weekend, Saturday might require a second look. The forecast from the National Weather Service warns of a "potential severe weather day across the region," replete with hazards that include "damaging winds, hail, and possibly a few tornadoes." Pittsburghers are advised to remain vigilant, as these storms could bring not only tempestuous winds but also flash flooding, owing to "torrential downpours." The Weather Prediction Center has cast a wary eye on the area, indicating a marginal risk for excessive rainfall that could lead to flooding.
But let's not forget, after the storms comes a respite — drier times ahead. The tail end of the weekend will see "a slight cool down Sunday and Monday," ushering in skies scrubbed clean by a cold front that will sweep away the rain. A "drier airmass" will move in, as stated by the National Weather Service, heralding a period of calm that should last until mid-week. However, don’t stash your umbrellas too far out of reach; another round of showers and thunderstorms is expected to make a comeback on Thursday as a new low-pressure system rolls in.
Pilots and passengers be advised, that aviation forecasts for Friday through Tuesday suggest potential visibility restrictions due to the anticipated weather conditions. Saturday, in particular, could see restrictions with showers and thunderstorms ahead of and along a crossing cold front, though a return to "VFR" (Visual Flight Rules) is expected by Sunday under the vigilant watch of high pressure.
