Forecasting Temperatures
scaffolding activity
Introduction:
Forecasting temperatures requires the consideration of many factors;
day or night, clear or cloudy skies, windy or calm, or will there be
any precipitation? An error in judgment on even one of these
factors may cause your forecasted temperature to be off by as
much as 20 degrees.
The purpose of this activity is to explore these factors in greater detail
and investigate their possible outcomes on forecasted temperatures.

useful information for answering the questions.
Forecasting Scenarios:
For each of the following weather scenarios, indicate what impact
each component (cloud cover |
winds |
advection |
snow cover) will have on forecasted temperatures.
Indicate whether each weather condition will lead to lower (L) or higher (H)
temperatures or indicate "None" if it is not a factor.
