Rain showers on your Sunday will slowly taper off from north to south as we move into evening. But it won't stay dry for long!
On Monday a stronger storm moves in. This storm will sweep across the region with moderate amounts of rain and most valley areas getting .50-1.00" of precipitation. The big story with this Christmas Eve weather system is snow. Snow levels will start out near 6000 feet but drop to 5000 feet or lower near the end of the storm. Most areas above 6000 feet will get a foot of snow or more from this storm and some locations could get nearly two feet! Chains will be required for most mountain drives and there could be delays and/or road closures.
On Tuesday, Christmas Day rain and snow showers will taper off very early in the morning leading to a mostly sunny, breezy and chilly day for your holiday. Temperatures will be cool.
Meanwhile the rest of the week after Christmas looks dry at this time except for some isolated very light showers at times in the mountains.
