THE CYCLONIC UPPER FLOW AND LOW LEVEL COLD ADVECTION IS RESULTING  
IN AN EXPANSIVE BROKEN TO OVERCAST DECK OF LOW CLOUDS SPREADING  
SOUTHEAST WITH TIME. THIS WILL HAVE AN IMPACT ON HIGH TEMPERATURES  
TODAY AND LOWERED TEMPS A FEW DEGREES WITHIN THE CLOUDY AREAS.  
HAVE ALSO INCREASED CLOUD COVER TO REFLECT CURRENT OBSERVATIONS.  
 
REMOVED THUNDER CHANCES FOR THIS MORNING AND TRIMMED THEM FOR THE  
AFTERNOON HOURS. THE BEST CHANCE FOR AN AFTERNOON THUNDERSTORM  
WOULD BE ACROSS NORTHWEST ARKANSAS.  
 
UPDATED FORECAST PRODUCTS HAVE BEEN SENT.
