Could Tri-Cities get NO SNOW on Christmas Day?
Even though we are currently experiencing La Niña in the Pacific Ocean, there is zero indication that the Tri-Cities area will be under snow in December. I took a look at the weather for a month out (look, I'm not an expert) and most days are expected to be in the forties, including the week of Christmas.
If you're planning to head east on I-84, you better postpone the trip. I-84 is closed both eastbound and westbound between Exit 216 (six miles east of Pendleton) and Exit 302 (near Baker City) due to severe weather with snow and ice on the road.
