BREEZY NORTHWESTERLY WINDS ARE EXPECTED TODAY, BUT OTHERWISE QUIET  
WEATHER CONDITIONS WILL PREVAIL. CLOUDS WILL BE ON THE INCREASE  
LATE THIS EVENING AND OVERNIGHT AHEAD OF THE NEXT STORM SYSTEM.  
RAIN SHOWERS ARE EXPECTED TO BEGIN ON SATURDAY MORNING, WITH  
CHANCES INCREASING RAPIDLY LATE IN THE MORNING AND INTO THE  
AFTERNOON HOURS. SOME SNOW MAY MIX IN WITH THE RAIN, BUT AT THIS  
TIME, IT APPEARS THE THREAT FOR ACCUMULATING SNOWFALL THROUGH THE  
AFTERNOON HOURS WILL REMAIN TO THE NORTH OF THE AREA DUE TO  
LINGERING WARMER SURFACE TEMPERATURES. HOWEVER, ANY SUBTLE  
SOUTHWARD SHIFT TO THE INCOMING AREA OF LOW PRESSURE WOULD BRING  
MORE A OF SNOWFALL THREAT TO THE LOCATION.  
 
PRECIPITATION CHANCES WILL GRADUALLY COME TO AN END THROUGH  
SATURDAY EVENING. AS COLDER AIR FILTERS IN FROM THE NORTHWEST,  
LINGERING LIGHT RAIN MAY CHANGE OVER TO LIGHT SNOW AFTER 8-9 PM OR  
SO, BUT LIGHTER PRECIPITATION RATES SHOULD PRECLUDE MORE THAN SOME  
A SLUSHY INCH OR SO OF ACCUMULATIONS ON GRASSY AND ELEVATED  
SURFACES.
