A burst of arctic air will plunge temperatures in San Luis Obispo County this week, reaching 20 degrees and possibly even teens in parts of the northern county.

Temperatures are expected to drop Tuesday evening to 38 degrees at Arroyo Grande and Grover Beach, 39 degrees at San Luis Obispo, 34 degrees at Atascadero and 33 degrees at Paso Robles, with snow forecast as low as 1,500 feet overnight.

But this is only the beginning. It will be even colder on Wednesday with overnight lows forecast to reach 23 degrees early Thursday morning in Paso Robles.

On Tuesday, the National Weather Service issued a winter weather advisory for the interior valleys of SLO County, including Paso Robles and Atascadero, in effect until noon Wednesday.

“This will be the coldest storm we have seen so far this winter season, with the potential for widespread impacts from snow and ice on many of our lower elevation passes, which could make travel difficult with potential delays or road closures.” Weather Service said in its notice. “Major roads likely to have snow/ice impacts include Highways 41, 46, and 58. Interior portions of Highway 101 may also experience a light dusting of snow Tuesday evening.

“Snowy and icy road conditions (are) expected, with total snow accumulations a dusting 1 inch on the valley floor and 1-2 inches in the foothills. Snow levels will drop to around 1,500 feet this evening. Winds of up to 40 mph will also result in dangerous wind chill readings and locally reduced visibilities in blowing snow,” according to the weather service.

PG&E meteorologist John Lindsey told the Tribune that it’s possible temperatures in parts of North County, including Creston and Paso Robles, could hit teenagers. The cold front is expected to be mostly dry after the onset of snow and showers Tuesday evening.

“Upper level winds are around 18,000 to 20,000 feet up – coming straight out of Canada. So (the winds) are blowing this cold air mass – really more or less an arctic air mass – south into the central coast,” Lindsey said.

While the cold weather is no surprise for this time of year, Lindsey said such freezing temperatures are unusual for the Central Coast.
