205 PM PDT FRI APR 20 2018  
   
BROADCAST DISCUSSION
 
A WEAK FRONT WILL BRING LIGHT RAIN TO  
THE AREA LATE TONIGHT AND EARLY SATURDAY MORNING, PARTICULARLY  
ACROSS OUR NORTHERN ZONES. HIGH PRESSURE AND OFFSHORE FLOW  
WILL BRING WARMER AND DRIER WEATHER TO THE AREA THROUGH AT  
LEAST EARLY NEXT WEEK.  
 
   
DISCUSSION
 
A FRONT SLIDING BY TO OUR NORTH WILL BRING LIGHT  
RAIN TO THE AREA LATE TONIGHT AND SATURDAY MORNING. WETTING  
RAINS WILL BE MOST LIKELY ACROSS THE WEST FACING SLOPES OF THE  
COAST RANGE AND CASCADES, PARTICULARLY ACROSS OUR NORTHERN  
ZONES. BUILDING HIGH PRESSURE WILL BRING INCREASING EAST WINDS,  
WARMER TEMPERATURES AND LOWER RELATIVE HUMIDITIES LATE SUNDAY  
AND MONDAY. WARM TEMPERATURES AND DRY WEATHER LOOK TO CONTINUE  
THROUGH AT LEAST THE MIDDLE OF NEXT WEEK. MODELS HAVE BEEN  
HINTING AT AN UPPER LEVEL LOW PRESSURE DRIFTING EAST-NORTHEASTWARD  
TOWARDS THE REGION LATE IN THE WEEK, WHICH WOULD BE A FAVORABLE  
PATTERN FOR THUNDERSTORMS TO DEVELOP OVER THE CASCADES AND SPREAD  
NORTHWESTWARD INTO THE WILLAMETTE VALLEY AND COASTAL ZONES.  
 

 
 
***WINDS ARE 20-FOOT 10 MINUTE AVERAGES***
