12z GFS shows Big Rain for DC area

the new GFS is very bullish on a slow moving rain event that would give us quite a bit of rain over the course of 4 days.

Here would be the total rain amount if it verified through August 2nd. It would make a huge dent into our drought

If this were to happen and its looking like a decent chance, the majority would fall early next week with it starting late in the weekend. I will keep you updated
