FXUS66 KLOX 192116 AFDLOX Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 216 PM PDT Thu Mar 19 2026 .SYNOPSIS...19/134 PM. Temperatures will remain well above normal through next week, though some cooling is expected this weekend. Areas of dense coastal fog is possible through the weekend as well. Temperatures will trend upward again next week but are not expected to be as hot as this week. && .SHORT TERM (TDY-SUN)...19/202 PM. In general temperatures today are either the same or a few degrees cooler than yesterday. Expecting one more day of similar temperatures before the current high pressure system starts shifting into AZ which will initiate a brief cooling trend over the weekend. Most areas except the far interior will experience 5-10 degrees of cooling this weekend, though that still keeps highs 10-20 degrees above normal. A shallow marine layer has begun to form over the coastal waters and many beaches will start out with dense fog the next few days and that will help cool off the coastal areas. In the meantime, it continues to be very hot with temperatures 20-30 degrees above normal Heat Advisories and Extreme Heat Warnings remain in effect through Friday. Based on the current forecast, there is only about a 30% chance of extending heat advisories into Saturday, and those would most likely be in the inland areas. .LONG TERM (MON-THU)...19/215 PM. Temperatures will slowly start to increase across inland areas Sunday and for coastal areas on Monday.
