As the major storm continues in Pittsburgh, the area is in for a wintry travel mess through Wednesday.
The storm will bring a total of 6 to 8 inches of snow, reduced only by the period of rain or wintry mix in some areas from Tuesday evening. Higher amounts are expected to the north and east of the city.
The snow threatens to cause slow and slippery travel, including on Interstates 70, 76 and 79. Increasingly winds will blow the snow around on Wednesday, reducing the visibility for motorists and making some roads that were previously plowed snow covered once again.
Airline passengers flying to or from Pittsburgh's International Airport should prepare for delays and possible cancellations, not just from the snow locally, but also due to the ripple effect from heavy rain and wind at airports along the East coast.
While the steady snow will end by Wednesday midday, there will be bands of lake-effect snow developing during the afternoon and night. Any untreated wet and slushy areas to start the day Wednesday will freeze as temperatures fall.
The storm will depart the Northeast by Thanksgiving Day, allowing a partly sunny and cold day to unfold in Pittsburgh. However, bands of lake-effect snow and snow showers will linger across the higher terrain of western Pennsylvania.
After a bout with midweek showers and storms, Seattle will have drier, pleasant weather that will carry into Wednesday.

Cooler weather through late week in Detroit will be replaced by more seasonable temperatures and thunderstorms for the weekend.
