Fall heat wave expected to bake San Luis Obispo County this weekend

A major fall warm-up is expected to heat up the Central Coast this weekend.

Local meteorologist John Lindsey says high temperatures will start rising Saturday. San Luis Obispo's expected high Saturday will be 84 degrees and then jump to 92 on Sunday. In Paso Robles, the high will rise to 94 on Sunday and 100 on Sunday.

"Gentle to moderate (8-to-18-mph) and at times gusty northeasterly (offshore) winds are forecast during the night and morning hours starting Saturday night through Monday," said Lindsey in his daily forecast. "These offshore winds will produce compressional heating in the coastal valleys and along the beaches."

The heat wave will extend into Monday, Lindsey said. "All of the beaches of San Luis Obispo County should see temperatures reach the low 80s as the marine layer is driven out to sea by the offshore winds. Monday appears to be the warmest day of the forecast period."

By Tuesday, fog will redevelop along the coast and conditions will cool down, Lindsey said. A storm system offshore will direct subtropical moisture overhead, with the possibility of cloudy skies and scattered showers.
