Scattered showers and mountain snow will continue today. Drier and milder conditions return this weekend and continue through most of next week.
The central part of the trough will move over Nevada this morning with the back end of the trough still over the region. Showers are expected to continue but should gradually taper during the day ending in the evening. Best chances continue to look to be over the eastern side of the valley and adjacent foothills and mountains. Only minimal additional snow accumulations are expected today.
Saturday a ridge of high pressure will start building over the region and will warm temperatures back to near seasonal normals with mid 70s expected for the valley and mainly 50s in the mountains. Continued warming is expected both Sunday and Monday with highs warming mostly into the lower 80s for the valley to mainly the 60s for the mountains.
Extended Discussion (Tuesday through Friday)
A ridge of high pressure will begin to flatten out Tuesday as a trough begins to move into the Pacific Northwest. The weak dry trough will move over California with some slight cooling each day on Tuesday and Wednesday and valley temperatures cooling back into the 70s. The far northern part of the state including the north end of the valley may have a chance to see a little bit of precipitation from the tail end of that trough but conditions continue to look mostly dry and breezy for both days. A deeper trough will move over the region next Thursday and will bring a better chance for some showers over the mountains and north end of the valley. The trough will move east of the area by next Friday with only some residual chances for some mountain showers left over the region.
