Course Policy: Since all of our schedules are very busy, there will be no make-up quizzes or exams. Missed quizzes and exams will receive a zero.

The Forecast Contest will be held on each Thursday (7 total). You will be asked to predict the maximum and minimum temperature between Saturday (7am) morning and Monday (7am) morning at the University Weather Observatory. You will also be asked to predict the total amount of liquid equivalent and solid precipitation.
Precipitation Categories: Liquid 0-Trace (1), .01-.10 (2), .11-.25 (3), .26-.50 (4), >.50 (5)
Solid 0-Trace (1), .1-1.0 (2), 1.1-3.0 (3), 3.1-6.0 (4), >6.0 (5) (all precip units are in hundredths and tenths of an inch)

Scoring the contest will be 1 point per temperature degree and 4 points per precipitation category.
For example: Forecast: Max=38, Min=22, Precip=0, Solid=0
Actual Max=41 (3pts), Min=21(1pt), Precip=1 (4pts), Solid=0 (0pts) TOTAL=8pts

The syllabus, class notes and schedule are all contained on the web page. Results of the forecast contest will be posted on Wednesday by class time.
