(NEW YORK) — An intensifying storm system will move out of the Ohio Valley and into the eastern Great Lakes and the northeast Tuesday, spreading rain over major cities from Washington, D.C., to Boston during the afternoon. Most areas will see approximately an inch of rain, while flash flooding is possible in some low-lying areas.
Some severe weather is possible from Richmond, Va., to Jacksonville, Fla., with gusting winds near 70 mph. A few isolated tornadoes could develop in some of the strongest storms. There is also a chance for some minor flash flooding in parts of the southeast on Tuesday.
As the system moves across Pennsylvania and New York, surface winds will increase to 40-to-50 mph with higher gusts along the coast. Wind advisories have already been issued from Delaware to Maine.
Light snow is expected on the back side of the storm, but not much for this time of the year. Areas around Detroit, Cleveland and Pittsburgh could see 1-2 inches of snow, while those near Erie, Pa., to Buffalo, N.Y., and into the Adirondacks could see 4-6 inches of snow. The highest elevations in the Adirondacks could get up to 8 inches.
The quick-moving system will be out of the northeast by mid-Wednesday morning, only to be followed by colder temps and gusting winds Wednesday afternoon.
