The weather in Missouri is very mysterious with a twist of unpredictability. It may be very humid with sunshine one day, and then the next week a winter storm may be in the forecast. Dressing for all four seasons, regardless of the actual season is your best bet to become acclimated to the climate. At the beginning of the school year, when summer is winding down, bring some shorts, khakis, T-shirts, and an umbrella. It seems to rain often in the fall. When winter begins, get out your scarves, hats, and a nice coat. The weather here can be wonderful or dreadful, but it's up to you to make the best out of each day.
The spontaneity of the weather is very exciting and a good experience to share with other students. Just prepare yourself for anything! Bring little bit of everything, expect the unexpected, and remember that every season brings a whole range of temperatures.
