Local 3-Month Temperature Outlook - Temperature Range Graph
The Temperature Range Graph provides the Local 3-Month Temperature Outlook for
thirteen future three-month periods. It shows the expected range of the average three month temperature (in
degrees Fahrenheit on the y-axis) for thirteen outlook periods (x-axis). Expected temperature ranges are
given for five confidence interval options: 99%, 95%, 90%, 75%, and 50%. A pull-down menu, to the right of
the graph, allows selection of the confidence interval. By default, the graph shows the Temperature Range
for the 99% confidence interval. In other words, for the default case, there is a 99% chance that the
temperature will fall in the range shown for a given three-month period. The plot also indicates the
1981-2010 median, which is the middle value from 1981-2010 observations (i.e., 50% of the time the observations
were higher than the median and 50% of the time the observations were lower than the median).
A text interpretation of the Temperature Range Graph is available for each three month period by mouse click
on the graph's vertical line for this period. "Text Interpretation" button below the graph links to the text
interpretation for all thirteen three-month periods in one document.
The table below the Temperature Range Graph displays corresponding numeric data. The table consists of 14
columns and 3 rows, with the first column identifying the data type and columns 2 through 14 providing the
data values for the three-month periods specified in row 1. The second row provides the 1981-2010 median. The
expected Temperature Range data for the selected confidence interval (or expected chance) are provided in the
third row. Each row contains two temperature values (in degrees Fahrenheit): the top value indicates the
maximum expected three-month temperature value and the bottom value indicates the minimum expected three-month
temperature value for the confidence interval specified in column 1 for this row.
