The cool front that come through last night has settled to our south.  Along that front a wave will bring more clouds and finally the chance for some needed rain showers by tomorrow morning.  Right now southern Maryland and the Eastern Shore, those areas that are the driest, are likely to see rain and 0.25" - 0.5" of needed rain.  Check out the Futurecast below.  Around DC 0.1" - 0.25" is what we should expect.  Not a drought buster but sure a help.  By late Sunday into Monday more and more it does look like finally a storm from the south will bring general rain, perhaps as much as a 1" to much of the area.
