here's meteorologist tyler malden. >> the weather map behind me is extremely busy. so let me show you the two systems at play over the next 72 hours. system number one is the cold front that pushed offshore the east coast yesterday. behind it, lake effect snow and we could see up to 6 inches of lake effect snow up here across the great lakes and on into the northeast. but then we have a series of weather makers pushing across the northern rockies and the northern plains. this system could create north of 10 inches of snow across the highest elevations and also extremely heavy rainfall across the coast of oregon and washington. that system is on the move to the east. it's the one that's going to impact our travel on wednesday. it's going to impact our thanksgiving and it's also going to impact black friday, too. in terms of thanksgiving itself, trouble spots will be seattle, and then also houston all the way up through st. louis on to chicago as well as the areas around the great lakes. christine, paula, back to you.
