Rain is on its way to San Luis Obispo County, forecasters say

It has been nearly two months since San Luis Obispo County got significant rainfall, but the area is about to enter a week of wet, cold weather, forecasters predict.

The National Weather Service is even calling for a chance of snow to fall in the inland areas of the North County on Monday night.

Skies will be cloudy today and remain so through Sunday as a storm system develops over the Pacific Northwest and starts moving southward. By Sunday night, rain is expected across the county, with showers continuing into Monday.

“The Pacific storm conveyor will start hurtling storms into California and the rest of the Southwest,” said John Kocet, a senior meteorologist with AccuWeather.com, a forecasting service based in State College, Pa. “That means significant rain will finally get into Central and Southern California.”

Between a quarter to a half inch of rain could fall Sunday night into Monday, according to the National Weather Service. Higher amounts could fall in the mountains.

Rain is likely to last through Monday and into Monday night, with an inch or more possible. The overnight low in Paso Robles on Monday night is expected to be 31 degrees, and the Weather Service forecast noted that regions of the Central Coast that are “vulnerable to the snow include interior San Luis Obispo County.” Lows elsewhere in the county will be in the upper 30s.

Showers will linger into Tuesday, then a second storm system arrives on Wednesday.

“This second system looks to be even wetter than the first, with a subtropical feed of moisture that originated from what used to be Typhoon Nida in the western Pacific,” the weather service said.

There is a chance of a third storm system reaching the Central Coast next weekend.

The gray skies will mean cool daytime temperatures — the high temperature in San Luis Obispo will stay in the 50s all week. Overnight lows will range from the low 30s in the North County to near 50 at the coast.

The last significant local rain fell on Oct. 13, the result of remnants of another typhoon that moved across the Pacific. More than seven inches were recorded in San Luis Obispo that day, and the storm shattered all-time records for a single day in the month of October.
