Forecasters expect cool and mostly dry conditions in the Portland area that will linger through the weekend, but early fog could slow early Thanksgiving travel.

Inevitably, someone somewhere in Houston will wake up bright and early on Thanksgiving morning in a cold sweat. A crucial ingredient, something that you swore you bought, will come up missing, resulting in a mad dash for the grocery store.
