Northern California is set for a chilly Monday morning, with temperatures near freezing and frost covering the Valley and Foothills, as reported by KCRA Meteorologist Kelly Curran. Residents are encouraged to dress in layers, as while hats, gloves, and coats are necessary in the morning, the afternoon is expected to be sunny and mild, with highs in the upper 50s and low 60s. Winds will be light across most regions, but some north breezes might occur along the western Sacramento Valley, Coastal Hills, and Delta, with gusts under 35 mph. The pleasant weather pattern is expected to continue into Tuesday and Wednesday, mirroring Monday's conditions. However, clouds will start to increase on Thursday ahead of a new storm system anticipated to bring rain and Sierra snow from Friday through Monday.

Meteorologists highlight the uncertainty surrounding the storm's timing, snow levels, and total precipitation, which will be better understood as the system approaches. The forecast indicates that this much-needed rain and snow will be a welcome addition for the region. Overall, the contrast between the cold mornings and mild afternoons serves as a reminder of the dynamic weather typical for Northern California during this time of year.
