Cold and dry weather is forecast through the weekend. A renewed chance of precipitation and breezy to windy conditions will return early next week.
An inside slider moving through the Great Basin today will bring some chances for some light snow showers over the mountains. Dry conditions are expected elsewhere. As the low moves east this evening showers will end over the mountains. Cold temperatures will remain over the region through the weekend. frosty mornings with below normal daytime highs are forecast through the weekend.
Overnight lows will mainly range from the upper 20s to mid 30s for the valley and foothills this morning then mid 20s to lower 30s this weekend. Daytime highs will mainly be in the 40s to lower 50s for the warmer spots in the valley today and Saturday.
Sunday will likely be the coldest morning for most locations in the valley while the foothills will likely see their coldest morning on Saturday.
North winds today into Saturday morning should help to dry out air near the surface and allow for more cooling in the valley on Sunday. Late Sunday night into early Monday a warmer weather system will begin to move over the far northern parts of the region.
Models and cluster analysis have indicated a much weaker system moving into the region early next week than 24 hours ago. Currently the daytime looks dry from around Sacramento south during the day with some chances of precipitation Monday night.
Extended Discussion (Tuesday through Friday)
The main part of the weather system on Monday moves east of the area on Tuesday with another shortwave moving into the region Tuesday evening. Showers will continue over the northern areas and mountains during the day.
Again the main focus of precipitation will be over the northern areas with lighter amounts possible down through Sacramento.
Overall precipitation continues to be lower than earlier forecasted, winds are a lot lower and snow a lot less with higher snow levels also now forecasted.
Thursday looks to be dry as the models now have a ridge moving over the region. Next Friday there is a lot of uncertainty with where a low pressure system may be located. Cluster analysis is indicating zonal flow over California for now with maybe some light amounts of precipitation possible.
