LONG TERM (FRI-MON)

19/1226 AM.

May Grey will return during the xtnd period. At the upper levels there will be fairly weak flow. At the sfc there will be steadily increasing onshore flow. By the weekend there will be moderate to strong onshore flow.

A more robust marine layer will likely develop each night through morning. The clouds will push a little deeper into the vly each day as well. By the weekend some beaches will struggle to clear. The increased onshore flow to the east will produce moderate southwest winds across the Antelope Valley and foothills during the weekend.

Fridays will see the biggest drop in temps with most areas falling by 4 to 6 degrees. A few more degrees of cooling are slated for Saturday and then little change is forecast for Sunday and Monday's temps. Highs over the weekend will range from the upper 60s to mid 70s across the csts with upper 70s to mid 80s for the vlys. As is typical with strong onshore flow, the csts/vly temps will be below normal while the interior temps will be a few degrees over normal.
