A powerful storm system is expected to develop this week and blast portions of the Northeast with heavy rain while accumulating snow is possible in the Ohio Valley and Appalachians.

Colorado could get bursts of snow in the mountains Monday night, while Denver could see a few flurries or snow showers Tuesday morning.

The heaviest precipitation is expected in Central New York and the Finger Lakes, which could see some lake effect snow or rain after the main storm moves through. Temperatures will likely be too warm for areas like Syracuse to see snow, but there’s a 50% chance that higher elevations like the Catskills will.

A series of storms is set to move across the US this week, and some of them could help bring much needed relief to areas experiencing drought.
