Last night's winter precipitation was highly variable across the Quad State, resulting in highly variable road conditions. The bulk of the problems will be focused bridges, untreated roads, and sidewalks. Temperatures are expected to climb to the freezing mark or a few degrees higher, which should lead to some improvement of road conditions. Any moisture that is left on road surfaces this evening will freeze, resulting in black ice tonight into Wednesday morning.
Well below normal temperatures will continue throughout the Quad State for the next week. The forecast is mostly dry, with no major weather systems expected. A reinforcing shot of cold air will arrive Wednesday night with the coldest air of the week expected Thursday. Wind chills Thursday morning will be in the single digits in some locations, and most areas will struggle to climb up to freezing that afternoon.
