We leave for Europe on August 23 and will be traveling through Munich/Salzburg/Prague for a little over a week. The weather forecast seems to be a bit all over the place - high 80s in the day and low 50s at night. To those who live in these cities or have travelled there recently, is that accurate? Trying to figure out what to pack and streamline what I am bringing if at all possible. Seems like it might be shorts and t-shirts for the days and jeans and light jackets at night? Does this sound right? Anyone have a good site for accurate temperatures? I worry weather.com doesn't have the best info. Any help you can provide would be helpful. Thanks!
