California Fire Weather Concerns

A LARGE RIDGE OF HIGH PRESSURE TO THE EAST WILL GRADUALLY BUILD WESTWARD THROUGH THE WEEK...BRINGING WARMER TEMPERATURES TO THE REGION...ESPECIALLY ACROSS INLAND AREAS. TRIPLE DIGIT HEAT WILL BE CONFINED TO THE ANTELOPE VALLEY...SANTA CLARITA VALLEY...AND LOWER MOUNTAIN ELEVATIONS TODAY...BUT WILL BECOME MORE WIDESPREAD ACROSS INTERIOR SECTIONS THROUGH THE WEEK. THE HIGH PRESSURE SYSTEM WILL CONTINUE TO SHRINK THE MARINE LAYER DEPTH AND BRING A DRYING TREND TO MUCH OF THE REGION. SINGLE DIGIT HUMIDITIES WILL OCCUR THE NEXT FEW DAYS ACROSS THE ANTELOPE VALLEY AND PORTIONS OF THE MOUNTAINS...WITH POOR OVERNIGHT RECOVERIES. LOCALLY GUSTY ONSHORE WINDS CAN BE EXPECTED EACH AFTERNOON AND EVENING ACROSS THE LOS ANGELES COUNTY MOUNTAINS...ANTELOPE VALLEY...AND SANTA CLARITA VALLEY. LOCALLY GUSTY SUNDOWNER WINDS WILL ALSO BE POSSIBLE WEDNESDAY NIGHT AND THURSDAY NIGHT...WITH POTENTIALLY VERY WARM AND DRY CONDITIONS ALONG THE SANTA BARBARA SOUTH COAST AND ADJACENT FOOTHILLS. MID-LEVEL MOISTURE MAY DEVELOP OVER THE REGION LATER THIS WEEK...BUT THUNDERSTORM CHANCES ARE MINIMAL DUE TO A FAIRLY STABLE AIR MASS. THE PROLONGED PERIOD OF VERY WARM AND DRY CONDITIONS WILL BRING HEIGHTENED FIRE WEATHER CONCERNS TO INTERIOR PORTIONS OF SOUTHWEST CALIFORNIA THROUGH THE WEEK.
