A great start to April with our high 62° right on the button for "average" high for April 2.  Early this morning did you see the wave clouds to the east of the Mall.  Here's a link to something we rarely see.  The dry air means temperatures will rapidly fall and that's the reason for the frost advisory and freeze warnings out but I don't expect any big problems right around DC.  Winds turn into the south and mild air back tomorrow and a general dry pattern into the Easter weekend which looks sunny and delightful right now
