2009: A STRONG UPPER LEVEL HIGH PRESSURE SYSTEM IS EXPECTED TO BUILD
INTO NORTHERN CALIFORNIA BY MONDAY...SHIFTING EASTWARD BY THE MIDDLE
OF NEXT WEEK. IN ADDITION...LONG RANGE COMPUTER MODELS ARE SHOWING
WEAK TO MODERATE OFFSHORE FLOW NEAR THE SURFACE FOR MUCH OF NEXT WEEK
DURING THE LATE NIGHT AND MORNING HOURS. WHILE THERE IS STILL CONSIDERABLE
UNCERTAINTY IN THE STRENGTH OF OFFSHORE WINDS ACROSS SOUTHERN
CALIFORNIA...THERE IS GOOD CONFIDENCE THAT HOT AND DRY CONDITIONS
WILL PREVAIL ACROSS INLAND AREAS MUCH OF NEXT WEEK...WITH TRIPLE DIGIT
HEAT BECOMING MORE COMMON AND HUMIDITIES LIKELY FALLING INTO SINGLE DIGITS
AT TIMES. WITH THE POTENTIAL FOR OFFSHORE FLOW...THE HOT AND DRY
CONDITIONS MAY SPREAD TO COASTAL AREAS AT SOME POINT NEXT WEEK.
1984: A tropical air mass lasting two weeks and high sea surface temperatures led to record.
1929: A tropical air mass enveloped Southern California.
The Meteorologist in Charge at San Diego reported temperatures of 111° in the coastal valleys on 9.16.
A reading of 94° was at San Diego at 4 am on this day.
1913: Santa Ana conditions produced a high of 110° at San Diego, which was the all time record high temperature until 9.26.1963 (when it hit 111°).
An unofficial report of 127° came from San Bernardino.
One died, a carpenter working outside. A few small fires occurred, including one downtown that destroyed one house.
History can be used as a prediction method of things to come, everything is lining up for very serious fire conditions, please use caution while working in the field.
