SYNOPSIS

11/913 AM.

Gusty Santa Ana winds will continue into much of next week, mainly across Los Angeles and Ventura Counties. There will be a warming trend into next week with near record temperatures possible.

LONG TERM (WED-SAT)

11/303 AM.

Light to moderate offshore flow with warm weather and clear skies is expected through the forecast period. Above normal heights will combine with these gradient values best on Wednesday and Thursday. Records for coast and valleys generally range from the mid 80s to low 90s during this period and could be challenged. In any case, highs will be around 10-15 degrees above normal most of the week. Upper-level support looks anemic during this period, but areas favored for northeast winds will likely be breezy overnight into the morning hours.

AI mdls indicate a small signal for rain after the 21th of Jan.
