NOTES:

Negative "Net" errors indicate forecasted temps cooler than actual.
Root Mean Squared (RMS) method is more sensitive to large absolute errors.
MAE is the Mean Absolute Error or average error without respect to being negative or positive
Forecast goal is +/- 3 degrees Fahrenheit; goal percentage is how frequently in period goal was accomplished
In everything but goal percentage, lower is better.
Highs are measured from 6AM - 8PM (recorded at 8:02 PM); lows from 6PM - 9AM (recorded at 9:03 AM)
Empty cells represent future (main table) or non-applicable (error summary) data.
