About this forecast

Can I plan a trip on a 2-week forecast?

Week one is solid for planning — accuracy is high. Week two shows the trend: go by the averages and the comparison with normal, and check the details closer to the date.

What does the "Vs normal" column mean?

It is the gap between the forecast and the climate normal for those same dates in Siam, IA, computed over 60 years. A positive value means the week runs warmer than usual.

Why are weekends shown separately?

Saturday and Sunday plans are what people check most, so we give them their own cards with temperature and precipitation.
