The Presidents' Day weekend is all too often the occasion for big snowstorms in the Washington area. The 1979 storm dropped 18.7 inches at Reagan National over a 2 day period and, more recently, the 2003 storm brought up to 28 inches in some of the western suburbs.  But while there is the potential for snow tomorrow, it is highly unlikely that history will repeat itself.  With the latest models showing the trajectory of a gathering storm  moving south of the DC area and then off the North Carolina coast - and with very little cold air in place - the greatest likelihood of heavy, wet snow will be to the south and west; those are the areas under a Winter Storm Watch from tomorrow morning through Sunday night. 

After a mostly sunny and mild day today in the immediate metro area with highs in the 50s, look for cloudy skies and breezy conditions overnight.  Sunday will feature a mix of rain and snow showers with a likely accumulation of less than one inch.  High pressure and sunshine return on Presidents' Day, a holiday that this year should require minimal digging out !
