Weather Synopsis for Sunday & Monday
A frontal system will push through the area today bringing low-elevation rain and mid and upper-elevation snow along with plenty of wind to the mountains. A warm front has lifted north early this morning with steadier precipitation near the Canadian border and more showery precipitation to the south. A cold front along the Washington coast will slide inland during the day, bringing a period of more moderate to heavy precipitation rates as it passes through the Cascades late morning/mid-day. Snow levels are slightly lower near the Cascade Passes and along the east slopes of the Cascades (2500-3500') and after the front's passage, we'll see snow levels rise to around 4000-4500' Sunday afternoon. Most areas will see moderate to strong S-SW ridgeline winds today. Mt Hood is on the southern fringe of this system and will see less precipitation relative to areas further north.
The low center associated with the frontal system will hang back and after a relative lull in precipitation rates, we should see showers increase with similar precipitation amounts and winds overnight but with slowly lower snow levels (3000-3500' by early Mon morning). Showers will stick with us through Monday morning and become more scattered in the afternoon. Sunbreaks along the eastern slopes of the Cascades along with few clouds will allow the freezing levels to bump up to 4000-4500' in the afternoon. Strong westerly winds will hang on in the Mt Hood area the longest.
