Very Cold New Year’s Eve Ahead, Warmup to Start 2022

After “round 2” of lowland snow brought 1-4 inches of snow to the Lowlands, another round of cold temperatures is in store for New Year’s Eve and early New Year’s Day.

Some snow melted during the day due to temperatures briefly rising to 33-36 degrees, but as of 9:50 PM Thursday, temperatures across Western Washington are below freezing (16-32°) once again.

New Year’s Eve (Friday) will have highs below freezing, as seen in the Euro model forecast below for high temperatures on Friday. 


Temperatures barely just reach freezing in the lowlands, and reach the mid to upper 30s on the coast. It will be a sunny day, so some snow melt is possible.

Temperatures around midnight will be quite cold, as seen in the HRRR forecast below. 


Expect midnight temperatures in the upper teens to mid 20s across the lowlands, and frigid temperatures of 5-15 degrees in Eastern Washington.

However, a light northerly wind will be blowing across most of the area, producing very cold wind chills at midnight. The HRRR wind chill forecast is below.


Expect wind chills in the low teens to low 20s, even colder in some outlying areas. Eastern Washington will experience wind chills of -10 to 15 degrees.

If you are watching the fireworks at the Space Needle, expect wind chills in the low teens to around 20.

The first say of 2022 will bring some change, as a significant warmup is expected. Temperatures will continually warm from Saturday morning through Sunday. The Euro forecast for temperatures at 1 PM Sunday is below.


By this time, temperatures have reached the low to mid 40s across most of Western Washington, and near 50 degrees on the coast.

However, it is very important to note that in recent snow events, forecast models have warmed up the region much too quickly, so this forecast may change. Some forecasts show brief heavy snow Sunday night, something that will need to be monitored.

Whenever temperatures are consistently above freezing, expect very wet roads with areas of ponding and standing water. This will be exacerbated with the potential for heavy rain late Sunday.
