AVIATION

140930Z....Coast/Valleys...Patchy intermittent low clouds continue with bases 1,800-2,000ft MSL along coastal locations as higher clouds around 25,000ft MSL make their way east. As higher clouds push east, low clouds will increase in coverage and push inland over the next few hours. Low clouds are expected to slowly fill into the Inland Empire, eventually filling most of the coastal basin by 12- 14Z. Low clouds lift near 2,500ft MSL and scatter out of inland areas 16-18z, but may linger into the early afternoon for coastal areas, particularly near KSAN. The south San Diego coast has a 50-70 percent chance of staying under low cloud cover with bases 2,000- 2,500ft MSL through the TAF period. Low clouds with similar bases will increase and fill into the San Diego valley 01-04Z Saturday, spreading north into Orange County 06-09Z Saturday.
