A cooler and wetter start to the forecast today as we head into a fairly chilly first day of Spring. Temperatures may only reach the upper 40s or lower 50s this afternoon under some widespread cloud coverage though the early rain chances will largely drop out after the lunch hour. Showers will linger a bit longer along the Central Coast, but for the most part we can expect a drying trend towards the end of the day.

Drier skies will linger into Tuesday with temperatures attempting to rebound a bit into the afternoon. Morning lows, however, will drop to near-freezing and, combined with some early fog cover, could make for a bit of a rough start to the first full day of Spring. Fast-forward to Tuesday afternoon, and temperatures could climb to the mid to upper 50s though that warming trend will be short-lived.

By the end of the week, thanks to more of a northwesterly flow in the forecast, cooler temperatures are set to settle in across the region. Afternoon highs will fall to the 40s and overnight lows could fall to near-freezing towards the weekend. That will help to drop the snow-line down to around 1,000 - 1,500 feet and could make for some snowflakes in the forecast at lower elevations than we have seen in a while.
