Pittsburgh residents can expect a climate reset today as a weak cold front moves across the region, bringing scattered showers and thunderstorms. The National Weather Service in Pittsburgh says this front will temporarily dial down temperatures to near normal levels before they creep back up again later in the week. Cold front and associated upper trough bring scattered showers/storms this morning and afternoon, the NWS stated, suggesting a shift in the recent weather pattern.
While the morning will see ongoing bursts of showers and the occasional storm, mainly to the southwest where instability can just manage to cook up thunder, the main band with the highest rainfall is projected to stick close to the I-80 corridor. Following the departure of the front, highs are going to be slightly lower than yesterday's, nodding to an ease-off in the recent heat. For those contemplating an evening stroll, scattered rain chances are expected to peter out by this afternoon or evening, according to the National Weather Service.
As we look forward to Thursday, the forecast anticipates a mostly dry spell brought on by renewed high pressure in the region. However, it's not completely to shake off the possibility of a few sporadic showers cropping up in the afternoon. The nearby presence of Hurricane Erin might nudge in some northeastern flow, but its effects appear to be minimal at this stage.
Looking ahead to the weekend, the thermometer is expected to quickly start to creep upwards as drier and warmer conditions take hold, before another cold front brushes through. This will increase the odds for rain from Saturday into Sunday, though expected amounts remain on the modest side for most areas. Early next week, cooler weather is anticipated to make a comeback with below-average temperatures, as a persistent eastern U.S. trough settles in.
In terms of aviation, those flying in or out of Pittsburgh might face isolated showers with low chances for lightning, mainly east of the city today. Pilots should also stay sharp for possible shifts in ceiling heights, which may sway category predictions during flights. After 03z, the weather shifts, ushering in conditions that could drop to IFR levels. High pressure nudging into the region from the west will aid in gradual cig improvements toward VFR Thursday afternoon, the NWS observed, providing a sliver of hope for clearer skies and smoother flights as the week progresses.
No advisories or warnings are currently in place for Pennsylvania, Ohio, or West Virginia. For further information and updates, travelers and residents can visit the National Weather Service website.
