Wind Advisory Issued for Susquehanna Valley: Strong Gusts Expected Sunday
A Wind Advisory is in effect from 9 AM Sunday, November 16, 2025, through 12 AM Monday, November 17, 2025, for the entire Susquehanna Valley, as a powerful cold front sweeps through the region. Residents should prepare for sustained winds of 15-25 mph and gusts potentially reaching 40 to 50 mph, particularly in higher elevations.
Scattered showers and isolated thunderstorms are currently moving across the area as of late Saturday night, November 15, 2025, according to local storm trackers. Radar indicates activity concentrated towards northern portions of Mifflin and Lebanon counties, extending into Franklin County communities like Chambersburg and Shippensburg. While these showers are expected to diminish overnight with the passage of the cold front, the subsequent shift in weather patterns will bring significantly increased wind speeds.
“Hold on to your hats,” one meteorologist warned, anticipating the dramatic change. The strongest winds are forecast to occur around lunchtime and into the afternoon on Sunday. These gusts pose a threat to unsecured objects, potentially causing rolling debris, downed tree limbs, and isolated power outages. Motorists, especially those operating high-profile vehicles, are advised to exercise extreme caution. Securing outdoor decorations and furniture is strongly recommended.
Sunday’s temperatures will start in the low to mid-50s before falling into the 40s as the afternoon progresses, accompanied by a mix of clouds and sunshine. Monday will remain blustery and cooler, with highs in the mid to upper 40s and continued west-northwesterly winds of 15-25 mph, gusting to 30 mph.
Looking ahead, Tuesday will be largely dry until evening, when a system passing to the south may bring a few showers. Temperatures will remain cooler than average, in the mid to upper 40s, with lighter winds. By the end of the week, temperatures are expected to moderate into the low to mid-50s, with the next chance for showers arriving Friday into Saturday.
A warm front preceding the cold front has already begun to raise temperatures, with readings in the 40s in areas like Lewistown, Selinsgrove, and Harrisburg, and climbing into the 60s near Chambersburg. This warm front is also contributing to the current scattered showers and severe thunderstorm warnings further west in West Virginia. The passage of the cold front will usher in significantly cooler and windier conditions, with a possibility of rain or even snow showers in the far northwestern communities, especially Sunday and potentially into early Monday.
Residents are encouraged to stay informed and take necessary precautions as the Susquehanna Valley braces for a windy and potentially disruptive Sunday.
