Each semester, 5 cities are picked for forecasting; the current city changes every 2 weeks.  Contestants <a href="/facts/Weather_forecasting/nzqyMFCa">forecast</a> 4 days per week for the following day's high <a href="/facts/Temperature/QyGe4gmj">temperature</a> (in <a href="/facts/Fahrenheit/2TVmyJod">Fahrenheit</a>), low temperature, maximum sustained wind speed (in <a href="/facts/Knot_(unit)/Sho0TF2y">knots</a>) and <a href="/facts/Precipitation_(meteorology)/uq3nGQc8">precipitation</a> (in 1/100ths of an inch).
</p><p>One "error" point is given for each degree of error on temperature, 1/2 an error point is given for each knot of wind speed error.
</p><p>Precipitation is scored as follows:
</p>
<ul><li>0.4 points for each .01 inch of error in the verification range from 0.00 to 0.10 inches inclusive</li>
<li>0.3 points for each .01 inch of error in the verification range from 0.11 to 0.25 inches inclusive</li>
<li>0.2 points for each .01 inch of error in the verification range from 0.26 to 0.50 inches inclusive</li>
<li>0.1 points for each .01 inch of error in the verification range over 0.50 inches</li></ul>
<p>At the end of the competition, the top 64 forecasters continue into a "March Madness" like tournament where a champion is crowned.  A trophy is given to the champion, as well as the runner-up and the other two forecasters who make it to the "Final Four".
