Forecasters said a persistent marine layer will keep coastal areas cooler, bringing morning low clouds and fog to parts of the coastal plain while inland communities experience significantly warmer conditions.
The National Weather Service warned that the combination of hot temperatures, low humidity, gusty winds and dry vegetation is increasing fire weather concerns across interior sections, including foothills, mountains and desert areas. Elevated-to-brief critical fire weather conditions are expected through Tuesday.
Relative humidity levels are forecast to range from 6% to 20%, while south to southwest winds could gust between 25 and 45 mph. Officials said these conditions could contribute to rapid fire spread in areas with dry vegetation.
Conditions are expected to moderate later in the week. From Wednesday through Friday, temperatures will cool and humidity levels will increase, reducing fire weather concerns.
For the Greater Pasadena area and San Gabriel Valley, Monday is forecast to be sunny with a high near 93 degrees. Winds are expected to remain light before turning southerly in the afternoon. Monday night will bring increasing clouds and lows around 59.
Tuesday is expected to be mostly sunny with a high near 83, followed by patchy fog Tuesday night and lows near 55.
By Wednesday, patchy morning fog is expected before skies clear to mostly sunny conditions with highs near 79. Temperatures will remain mild through Thursday and Friday, with sunny skies and highs in the mid to upper 70s.
