Hi everyone, apologies if I am doing this wrong, you all seem like you know a lot about weather and I really would like some information/knowledge from folks that understand this stuff really well! My partner and I are planning a camping trip to Mammoth Cave Nat'l Park next week (it's spring break in Chicago), and I've been paying close attention to the NWS out of Louisville. Unfortunately it looks like rain is in the forecast for next week, which is not a great addition to a camping trip. I know that more than five days out forecasts can be inaccurate, but I have been paying attention to the forecast discussion on their site as well. I don't understand all of the technical things they are talking about, but I've figured out that there is some sort of weather system that is forecast to push through the upper South/lower Midwest next week that will bring rain with it. With that in mind I have a few questions that I hope you guys can help explain for me: 1.) Is this forecast just saying that there is a higher probability of rain, or is it saying that it will rain and it's really just a question of how much? 2.) If it is going to rain next week, will it be a lot, or will it just be raining off an on, or for parts of the day(s)? 3.) Is this a weather system that will impact a large area? I am thinking if we're certain it won't be good weather in Mammoth Cave, KY we might pick a different national recreation area or state park (such as Mark Twain National Forest, or Hoosier National Forest) instead. Thank you all so much for your time, talent and knowledge, and if this post doesn't belong here, please let me know and I'll gladly delete it.
