How reliable is a long-range forecast?

The first three to five days for Collinsville are the most dependable. After about a week, a forecast gives a trend rather than an exact figure: the daily temperature can be off by several degrees and the timing of rain can shift by a day or more. Use the later days to plan broadly and check the page again as the date approaches, since it is updated several times a day.
