The briefing ended up lasting 20 minutes. The difficulty was a trough lying over the destination and, between him and it, an occluded front. A large area of IFR and marginal VFR weather blanketed northern Ohio and much of Pennsylvania, with patches of snow, freezing rain and drizzle. The temperature profile was complicated, with a couple of inversions, a freezing level at 4,000 feet and a high likelihood of snow and moderate rime icing in clouds up to 7,500 feet. Cloud tops were mostly around 6,500, and winds were out of the west, 45 knots at 4,500 feet and more than 50 knots at 7,000. Low-level wind shear was probable.
