DISCUSSION
 
HIGH PRESSURE WITH HOT, DRY CONDITIONS WILL CONTINUE  
THROUGH THE WEEKEND AND PEAK ON SUNDAY. INCLUDED GUSTS FOR  
SATURDAY AND SUNDAY AFTERNOON, BUT HAVE LOW CONFIDENCE THAT THEY  
WILL OCCUR GIVEN THE OBS DON'T SHOW ANY. A FRONT WILL WEAKEN AS  
IT MOVES THROUGH THE REGION ON MONDAY. IT IS UNLIKELY THIS WILL  
BRING ANY MEASURABLE PRECIPITATION NEAR THIS LOCATION. IF ANY  
CAUSE SHOWERS IN THE REGION AND WOULD EXPECT VIRGA IF ANYTHING,  
WHICH WOULD CAUSE MORE VARIABILITY IN WINDS. THE FRONT WILL BRING  
INCREASED CLOUD COVER AND COOLER AFTERNOONS WITH IMPROVING  
RECOVERIES OVERNIGHT.
