In Maryland, we battle Leaf Spot and Early Blight. This is what 9 days of good weather for tomato disease looks like (below). First you need rain to help the spores splash onto the leaves CHECK. You need continuous moisture in the form of rain or humidity to help the spores establish and spread upwards on the tomatoes  DOUBLE CHECK. You need warm temperatures with a day an night temperature averaging in the mid 80's CHECK.

I have been spraying my tomatoes with wettable sulfur (switched from baking soda). I have sprayed them with a standard does (weekly for July) and will spray the bottom leaves every other day with a milder dose. I have had very little disease thus far. However, July is when EB arrives to our Zone 7 gardens. Good Luck! If you don't spray preventatively... now is the time.
