SACRAMENTO,Calif.- increasing breezes Monday foreshadow a cooler week and the potential for regional showers as a storm system approaches the West Coast.
Winds will become more noticeable throughout the day, with valley temperatures expected to reach around 83 degrees. Foothill highs will be in the low 80s with lighter winds, while the Sierra Nevada will experience the strongest breezes, peaking near 70 degrees.
The strengthening winds are a result of a trough of low pressure moving toward the California coast. While the initial front is forecast to pass early Tuesday morning, the low-pressure system is expected to stall over the state. This positioning raises the possibility of post-frontal convection, bringing showers and isolated thunderstorms to the region from Tuesday through Thursday.
The Sierra Nevada is anticipated to receive the most significant stormy activity, with a chance of showers extending into the foothills. Valley rain is less certain, though a stray shower cannot be ruled out.
High temperatures in the valleys will fall into the low 80s by midweek. The system is predicted to move eastward by Thursday, paving the way for a warmer and sunnier Friday.
