Another powerful, historic winter storm is moving into Oklahoma and Kansas and heading toward the Great Lakes.  So far Amarillo, TX has gotten 17" and a blizzard with howling winds.  The storm is dramatic when seen from space. 

Another, secondary storm is forming in the south and will be the big rain producer for us tomorrow.  Here is our hyperlocal futurecast for tomorrow evening. 

Most areas will see 1" of rain,or more, and is the reason for the flood watch around the metro area. The rain may begin as a period of sleet and slight iciness well to the west of D.C. but this will be a rain storm, not a winter storm  Dry mild air comes in back of the storm Tuesday night and Wednesday will be sunny and even a touch of spring.
