Cool dry air continues to come in on northerly winds.  Great blue skies and excellent visibility but after sunset the temperatures will really tumble.  A Freeze Warning is out for areas west and north of DC.  Northern Maryland will see temperatures into the high 20s by dawn.  It's still a general dry pattern into next week.  Easter Sunday will be sunny but chilly for the Sunrise Services at 6:41AM.  No sign of storms or any soaking rains which we could use as dryness grows and the fire danger increases.  Rain deficit since January 1 now close to 4".  Enjoy the weekend and let's hope this pattern changes and we get some needed rain soon.
