Not sure what website you are using, but if you watch the long range forecast on Weather Channel on TV it is very apparent they are going to get a ton of rain on Friday. And then go to the internet and do a Baltimore forecast, on the 5 day forecast they even put bright orange letters on Friday that says \"potential for heavy rainfall\".
The prospect of having 2 inches of rain fall during the day makes it very tough to get enthused about handicapping it, especially the turf races.
But the real worry is, depending on what time it stops and how much there is, how dry will things be on Sat, especially the turf.
