Voters heading to polls on Election Day will have clear, sunny and warm conditions, forecasters say, though not as hot as Monday, when two local records were set.

The high temperature at the San Luis Obispo County Regional Airport reached 96 degrees, breaking the previous record for the date of 92 set in 1949, said meteorologist John Lindsey.

The high in Paso Robles reached 90, eclipsing the record of 89 degrees, also set in 1949, said the National Weather Service.

Lindsey said a weather station he monitors in Los Osos, located on Cottontail Lane in Bayview Heights, registered 93 degrees at 1:11 p.m. That was the hottest reading Lindsey had seen in 10 years of gathering data for Los Osos.

The heat was caused by high pressure over Nevada and Utah, which creates winds that blow toward the Pacific Ocean. When the winds flow from the land to the sea, they compress as they go over the Santa Lucia Mountains and heat up.

Offshore winds will continue Tuesday morning, but won’t be as strong as days past. Tuesday’s high should be near 85 degrees in San Luis Obispo and Paso Robles, forecasts said.

Highs on Wednesday will fall back into the low to mid-70s as winds turn onshore. A storm system moving down the West Coast will arrive in San Luis Obispo County on Thursday. Daytime temperatures will lower into the 60s. Showers are expected Thursday night and will continue into Friday, Lindsey said.

Early Friday morning it will be cold enough to allow for a dusting of snow on coastal mountains if showers occur, he added. Stiff winds and cloudy skies will make Friday chilly, with highs just in the 50s to low 60s, Lindsey said.

Clearing begins on Saturday, and daytime temperatures will start to warm up.
