SYNOPSIS
TRANQUIL WEATHER WILL CONTINUE INTO THE HOLIDAY WEEKEND WITH MINOR
DAY TO DAY CHANGES. A RIDGE OF HIGH PRESSURE IS EXPECTED TO MOVE
INTO THE AREA BY THE FIRST HALF OF NEXT WEEK, PROMPTING A WARMING
TREND OVER THE REGION WITH INCREASED HEAT RISK.
DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...
A WEAK TROUGH CURRENTLY OVER SOCAL CONTINUES TO PRODUCE MID LEVEL
CUMULUS ACROSS PLACES LIKE BIG BEAR INTO THE HIGH DESERT. LOW
CLOUDS CONTINUE TO CLING TO SOME AREAS TO THE COAST, WITH
SATELLITE SHOWING TRENDS OF CLOUDS RETREATING BACK INLAND AT THIS
HOUR. CLOUDS WILL PUSH INLAND TO ABOUT THE SAME EXTENT AS THIS
MORNING WITH PATCHY FOG ACROSS THE WESTERN VALLEYS.
A SERIES OF WEAK TROUGHS FROM THE NORTH AND WEST WILL MOVE ACROSS
OUR AREA, KEEPING THE WEATHER PATTERN BENIGN WITH HIGHS NEAR
NORMAL. FOR INDEPENDENCE DAY ITSELF, HIGHS WILL IN THE LOW 70S TO
LOWER 90S WEST OF THE MOUNTAINS, 70S/80S IN THE MOUNTAINS, 90S IN
THE HIGH DESERT AND NEAR 105-110 ACROSS THE LOWER DESERTS. SIMILAR
TEMPERATURES CAN BE EXPECTED EACH DAY THROUGH THE WEEKEND.
MODELS ARE VERY GOOD AGREEMENT ON A RIDGE HIGH PRESSURE MOVING
INTO OUR REGION BY EARLY NEXT WEEK. THIS WILL LEAD TO A SHALLOWER
MARINE LAYER WITH LOW CLOUDS STAYING NEAR THE COAST, ALONG WITH
WARMER TEMPERATURES. WARMEST TEMPERATURES WILL OCCUR AROUND THE
MIDDLE OF NEXT WEEK, WITH INCREASING CHANCES FOR HIGHS IN THE
TRIPLE DIGITS ACROSS THE INLAND EMPIRE AND TEMPERATURES NEARING
115 DEGREES ACROSS THE LOWER DESERTS. MODEL TRENDS SHOW A SUBTLE
INCREASE IN MOISTURE (PWAT) INTO THE MIDDLE OF THE WEEK. NBM
CHANCES FOR ANY STORM ACTIVITY ARE BELOW 10 PERCENT BY TUESDAY AND
WEDNESDAY, THOUGH CUMULUS CLOUDS MAY AT LEAST FORM OVER OUR HIGHER
TERRAIN. CONFIDENCE CONTINUES TO REMAIN LOW ON ANY STORM ACTIVITY
AT THIS TIME, BUT WE WILL CONTINUE TO REFINE THIS FORECAST IN THE
COMING DAYS.
