An upper-level low pressure system is bringing rain, wind and cold daytime highs to the Central Coast. Most of the early morning temperatures will be around the 40s and temperatures are only expected to go up an additional 10-15 degrees from there, reaching the mid to upper 50s for peak daytime highs.
As for the rain, overnight showers brought close to 0.25'' of rain for areas like San Luis Obispo, and just over that for Los Osos. Rainfall will be showery and heavy at times throughout most of Wednesday, but still rainfall totals are expected to stay around 0.50'' through Thursday. Snow levels are still going to drop to about 3,000 feet, which could result in hazardous driving conditions for those commuting through the I-5 corridor. Otherwise, it's still possible that parts of the deep interior valleys in San Luis Obispo and Santa Barbara Counties could see light snow by Thursday.
Southerly winds will be mild through the morning commute Wednesday, but by the afternoon conditions could be gusty. Wind gusts will shift out of the northwest by the afternoon and have the potential to reach 25-30 miles per hour.
The weekend will bring mostly clear skies and warmer temperatures that could get fairly close to the 70s.
