NZUS51 KCTP 011958 WRKMIS A cold front will move west to east across the airspace tonight. Showers and thunderstorms ahead of the front have, for the most part, moved east of the area, though an isolated storm or two could cause temporary reductions in visibilities and cigs through 01/22Z. A second area of pcpn developing now over northeast Ohio will move into and produce reduced conds over western PA later this afternoon and this evening. Gusty northwest winds will overspread the region behind the cold front passage tonight and persist into Thursday. Isolated to scattered snow showers will develop over the northern mountains and possibly the Laurels late tonight into Thurday with VFR expected elsewhere.
