Control order of stacked figure in ggplot2

My data is structured similar to the example below:

Quarter <- c("Q1", "Q2", "Q2", "Q3", "Q4")
Weather <- c("cloudy", "cloudy", "sunny", "sunny", "cloudy")
Duration <- c(16, 10, 12, 15, 14)
WeatherCondData <- data.frame(Quarter, Weather, Duration)

When I plot this data, the second entry for quarter two (Q2) is sunny however, isn't displayed in sequential order in the plot - cloudy is the second entry. 

ggplot(WeatherCondData, aes(x = Quarter, y = Duration, fill = Weather)) +
  geom_bar(stat = "identity", position = "stack") +
  theme_classic()

How do I change the plot so that sunny is the top part of the stacked bar for Q2?

Thanks.

Use stringsAsFactors = F to disable auto factor conversion in data.frame(). Then use factor() with levels args to set the order.

WeatherCondData <- data.frame(Quarter, Weather, Duration, stringsAsFactors = F)
WeatherCondData$Weather <- factor(WeatherCondData$Weather, levels=c('sunny','cloudy'))
