That's not criminal, that's totally normal. All those satellite's have made for better radar, that's it. I never believe the long range forecast, ever. The weather will never cooperate, and now you realize that.
Keep the soil moist, not wet, but don't let it dry out. Hold off on the fertilizer till the second week of Sept. Put a 2 inch layer of straw over the seedling's, that will keep thing's from drying out. You will be fine, don't let it get to you. Good luck.
