Low pressure systems keep San Diego temperatures cool

SAN DIEGO (KUSI) — A trough of low pressure is taking control of the western states Monday, keeping temperatures below average for this time of year.

Two low pressure systems follow the trough of low pressure this week. The first system won’t bring many weather changes. It will create a thicker marine layer with slight chances of drizzle overnight Monday. Any drizzle is not expected to be widespread though.

The second low pressure system is expected to be stronger. It may bring some instability for the mountains. Strong onshore flow will create gusty winds for the mountain and desert areas beginning overnight Tuesday. The system will generate slightly stronger sprinkles with chances of thunderstorms in the mountains.

Temperatures are expected to be cool Monday. They remain below average for this time of year and are not expected to change much throughout the week. Highs are expected to be 65 degrees along the coast, 67 degrees inland, 57 degrees in the mountains and 87 degrees for the deserts.
