Tuesday - November 18, 2025 @ 530 AM EST: A weak ridge of high pressure over the Commonwealth will bring a brief period of clearing early today before clouds thicken up from the west later this morning through the afternoon, well ahead of low pressure located over Missouri at daybreak. This weather feature will spread a shield of chilly, steady rain across the southwestern third of Pennsylvania this afternoon and evening. As the precipitation drifts north toward the Interstate 80 corridor this evening, the air will be cold enough to allow a mixture of rain and wet snow to occur. There could be a light coating of snow on the highest ridge tops of Central PA overnight.
