Wind-Driven Storms Surge Toward Eastern PA, Southern NY Tonight — SevereWX
A potent band of thunderstorms is racing eastward across the northern Mid-Atlantic, packing gusts up to 70 mph and hail to 1.25 inches as it nears eastern Pennsylvania and southern New York.
SPC's Mesoscale Discussion 1096 highlights this north-south oriented line of storms, currently over central PA, southern NY, and eastern WV, moving at 30-35 mph. These storms have already notched gusts over 45 mph and show potential to intensify in a juicy environment of lower 90s temps, 70s dewpoints, and steep low-level lapse rates.
By around 01Z (9 PM EDT), expect the line to plow into eastern PA and adjacent areas, including parts of NJ, MD, and DE. Unidirectional 35-kt flow near the surface bolsters the straight-line wind risk, with peak gusts of 55-70 mph most probable. Scattered damaging winds remain the headline, though quarter-size hail is possible too.
With an 80% chance of a watch issuance within the hour, folks from Philadelphia to NYC suburbs should prepare. SPC's graphic outlines the threat zone — check SPC website for details.
Stay prepared: Monitor local NWS updates, secure outdoor items, and have a severe weather plan ready. Avoid flooded roads and downed lines if storms hit.
