SYNOPSIS

A warmer day will occur across the region today. The weather will continue to be fairly benign and unchanged from day to day this week with marine layer clouds making an appearance each evening and morning along the coast into far western valleys. Slight cooling may occur by next week as a low pressure system brushes by to the north.

..Updated Aviation / Marine Discussions

A low pressure system across the intermountain west continues to push eastward, allowing the flow aloft to become more zonal over Southern California. This will bring in warmer weather to the area compared to yesterday with highs generally 3-7 degrees higher.

The flow generally remains zonal, weakly ridging through the upcoming work week. This will lead to minor day to day changes in the tranquil weather pattern across the region. Onshore flow will keep most areas similar each day. Desert areas will warm slightly each day, peaking around Wednesday as an area of high pressure over the East Pac tries to expand over the region. Areas along and west of the mountains will be near average for the week with highs in the deserts in the 90s and lower 100s. The marine layer will maintain a similar depth, bringing in low clouds each evening and morning to the coast and far western valleys.

An area of low pressure is expected to move into the Pacific Northwest sometime around Friday, moving across the western part of the country by next weekend. Models continue to show some discrepancies on the timing and depth of this system. Depending how strong and how far south this system goes, will depend on how cool we become; all in all though, another nice weekend is on tap as we head into the month of June.
