A new low pressure system approaches the Oregon coast Tuesday evening and into Wednesday bringing a rather warm front into the metro area for Wednesday. Most of Wednesday’s rain will fall in the later afternoon with heavy showers at times through Wednesday night. The high will be warm for the season at 57 degrees.

This warm air mass will raise the snow levels well above the Cascade passes. Generally, ski areas will see damp conditions and even rain on Wednesday.

Colder air will move in behind the front Thursday and snow levels will lower down to the Cascade passes for the remainder of the week.

A little milder this afternoon, but Arctic air is diving south and will arrive tomorrow. Lows in the 20s and highs in the 40s, but warmer by the weekend! #gawx #scwx @WSAVKrisA @wsavleeh @wsavariellas pic.twitter.com/gxpucPnfJe — Kyle Dennis (@KyleDennisWx) January 16, 2018
