The heaviest rain and potential for flooding is along the Transverse Range where 4-7\u201d total may fall.  Los Angeles will see 1-2\u201d over the next 48-hours \u2014 welcome precipitation.</p><p>The low will move into the Southwest this weekend and then combine with another upper-level shortwave in the Rockies to yield our next storm system for Christmas Eve that could bring significant snowfall to Denver.</p>",
