Pattern Shifts in Southern California

February started off very warm for Southern California, with many record highs tied or broken over the last week. We have also seen the typical set-up for warm, offshore winds known as Santa Ana winds, which heightened fire danger for the weekend.  The Red Flag Warning for critical fire weather conditions continues through Sunday evening before we see a big pattern change to kick off the new workweek. Surface low pressure will be cut off or stalled as we get into the beginning of the week. This will help bring in more moisture from the Pacific Ocean and much cooler air, which will drop temperatures during the week and lead to chances of rain back in the forecast during the week.
