Ruh roh...paging @Blizzard of 93 straight from MU's warminsta himself!
(1/2) A weak disturbance near the base of an upper-level trough over southeastern Canada will pivot through NY and PA on Wednesday. Expect isolated showers to erupt during the afternoon/evening hours, and I can't even rule out some #graupel due to the presence of cold air aloft..
(2/2) The freezing level on Wednesday will only be about 5,000 ft. above the ground, and rapidly ↓ temps with ↑ height indicate an unstable atmosphere. Graupel forms when supercooled water droplets accumulate and freeze on falling snowflakes and will be most likely N/W of I-81.
