Above..satellite + radar.....notice rain and clouds in South pushing north....notice clouds over Great Lakes pushing south .....these 2 jet stream will likely merge forcing southern storm to intensify off Mid Atlantic Coast Saturday. HEAVY RAIN with this system from Mid Altnatic to New England...which could easily end as wet snow across the interior Saturday evening. Windy and colder behind it. Weather elsewhere and through next week....quiet. Below - animated maps - rainfall through Tuesday....and snapshot weather for Friday. Be safe.
