UPDATE
 
 
15Z OBSERVATIONS RUNNING A FEW DEGREES BELOW THOSE WE SAW THIS  
SAME TIME ON FRIDAY. DEWPOINTS ARE NEAR TO A DEGREE OR SO HIGHER  
COMPARED TO 24HRS AGO AS WELL. CU FIELD IS DEVELOPING A LITTLE  
EARLIER THAN FRIDAY AS WELL ACROSS OUR SOUTHERN MOST ZONES AND  
LATEST MESO ANALYSIS SUGGESTS THIS IS WHERE THE HIGHER PWATS ARE  
LOCATED, IN PROXIMITY TO THE UPPER LEVEL LOW ACROSS THE S LA  
COAST. THIS IS ALSO WHERE OUR HIGHEST POPS ARE FOR TODAY SO FOR  
THAT REASON, NOT EXPECTING TO HAVE TO MAKE ANY CHANGES TO THE  
ONGOING FORECAST OR THE CURRENT HEAT ADVISORY WHICH WAS EXPANDED  
TO INCLUDE OUR ENTIRE REGION EARLY THIS MORNING.
