In the worst-case scenario, an intense storm, turns inland from the Atlantic Ocean over New Jersey and Pennsylvania early next week.
Such a scenario would deliver high winds, heavy rain and perhaps high-elevation snow. Impacts would range from travel disruptions and foiled activities to downed trees, power outages and flash and urban flooding.
If the storm fails to turn westward over the region, a period or two of rain would occur Saturday night into Monday. Snow showers could occur over the mountains by early next week with noticeably blustery, progressively colder conditions for all.
Tropical Storm Matthew has formed in the Caribbean could take a turn toward the United States as a hurricane next week.
