Fair and warm weather again today will be transitioning to cooler conditions on Monday as an upper-level low pressure system drops south over the deserts. The low will intensify over northwest Mexico on Tuesday, resulting in some gusty northeast winds over the San Bernardino Mountains and Inland Empire. Warmer in the valleys on Tuesday due to offshore flow. Some clouds and moisture will wrap westward around the low on Wednesday, sparking a small chance for showers. Much cooler with more marine clouds for the remainder of the week as a large trough settles in over the West with gusty onshore flow and a chance of early season showers along and west of the mountains.

The autumnal equinox is Monday, September 23rd at 12:50am.
