SLO County weather forecast for the week of Jan. 31: More rain is on the way
After last week’s atmospheric river (AR) produced significant amounts of rain throughout the Central Coast, partly cloudy skies will continue through Monday before an upper-level low-pressure produces rain on Tuesday.
Gentle to moderate (8 to 18 mph) variable winds, partly cloudy skies, night and morning dense fog and dry weather are forecast on Sunday into Monday.
An upper-level low-pressure system (546 dm) off the Central Coast will produce moderate to fresh (13 to 24 mph) southerly winds and between 0.25 and 0.75 of an of inch of rain on Tuesday. Strong to gale-force (25 to 3 mph) northwesterly winds and mostly clear skies will follow on Wednesday.
Fair and dry weather is expected over the latter half of next week as high pressure rebuilds over the Central Coast, encouraging a gentle warming trend. Daytime highs are favored to warm into the 60s, accompanied by morning low temperatures in the low to high 30s with warmer temperatures along the immediate coast. Long-range models show dry weather continuing through next weekend, with the next chance of precipitation indicated for the following week.
