Just in time for the holiday, temperatures in the days ahead will be much cooler -- and appropriately gloomy -- unlike last week when record-setting temperatures sent many seeking shade. 

National Weather Service meteorologist Tom Fisher said the Central Coast now is in a period of onshore flow, which is a change from last week's conditions. In fact, last Monday was 50 degrees higher than what weather experts recorded this Monday. 

Fisher said daytime temperatures across the Central Coast this week will be in the mid-60s and in the low-50s at night -- nowhere near record-breaking. While thermometers registered temperatures in the mid-60s Monday at the Santa Maria Public Airport, they were far from the record high of 95 degrees set in 1939 or the record low of 26 degrees set in 1971, according to the National Weather Service. 

On Halloween night, trick-or-treaters in the Santa Maria Valley will experience cool temperatures and overcast skies, Fisher said.

"We expect the enhanced marine layer to move through Tuesday afternoon and expect onshore flow and overcast conditions on Halloween night," the meteorologist explained. 

The onshore flow will also enhance the marine layer into the week, pushing it further inland, he added.

Though there is a 10-percent chance of some drizzle accompanying the marine layer, Fisher said, there is a real chance for rain later in the week.

“We are forecasting a frontal passage with some sort of precipitation this weekend, sometime between Friday and Sunday. Our computer models are all over the place,” he said.

John Lindsey, meteorologist for Pacific Gas and Electric Co. at Diablo Canyon Power Plant, agrees with Fisher.

According to PG&E’s weather expert, a front will come to the Central Coast from the Gulf of Alaska, bringing cooler temperatures, winds and moisture with it.

“An associated cold front is forecast to move through the Central Coast on Saturday with fresh to strong -- 19 to 31 mph- southeasterly winds and periods of rain,” Lindsey said in his Monday forecast.
