Improving chances
Posted: 20 Sep 2012 05:43 AM
This chart has been featured a number of times this summer season as it
shows the chances that this year will become the warmest on record for
Des Moines. The bottom charts shows that while we faltered some with
some cool weather in August, the warm weather in September has boosted
us back up to the best chances yet that this year will beat 1931 (the
current warmest). The brown spaghetti lines represent all previous
years appended onto this year until the end of the year and so
represents scenarios if we have any reasonable repeat of previous
years. Using these scenarios, 86% of previous years appended onto this
one would result in 2012 being the warmest on record. These lines
would also suggest that 2012 will remain warmer than 1931 until at
least the first week of December.
