High pressure that is currently building across the Ohio Valley and into the mid-Atlantic states early morning is going to provide the Greater Baltimore Area with a good deal of sunshine Friday, and temperatures will wind up close to 50 Friday afternoon. While there will be a bit of a breeze, it should average less than 15 mph.
Friday night will be chilly, and then some sun Saturday will begin to fade behind increasing clouds. A storm that is currently deepening in the Plains states is causing a raging snowstorm in the Denver Metro early Friday morning, as well as triggering some severe thunderstorms in Kansas and western portions of Oklahoma.
During the next 24-36 hours, moisture originating from this entity will begin to spread out across the Tennessee Valley and the southern Appalachians. Eventually, this will be causing some rain to move out across the Smoky Mountains and into Virginia by the end of the day Saturday. Then late Saturday night and early Sunday morning, the Greater Baltimore Area should see some of this rain. While the rain may briefly mix with some wet snowflakes, there should be little or no snowfall accumulation on Sunday.
