Current Year to Date numerical data with projections based on historical data since 1895.
On the left are Annual and Oct-Sept Rainy Season totals to date, an estimate for the whole period and the year's rank since 1895. Lower rankings are wetter. Below is average annual and remaining Average - YtD. Below are Historical and Rainy Season Min/Max and year.
On the right is the data date and current month total.
Below are two comparisons of current month to estimates based on the historical data. The Trapezoid Estimate uses a linear estimate based on the slope of the previous, current and next month averages. The Polynomial Function uses a 4th order polynomial to fit a curve through the prior two, current and next two months' averages.

AnnualTotals

Annual Rain Totals and trend since 1895. Total rain over the years has a decreasing* trend, about 0.056in/yr. A few wet years, as occurred around 1900, could negate or reverse the trend.
OTOH, a polynomial function shows that rain is increasing for the last couple of decades. Data over a longer time frame would give higher reliability, unless the data is chaotic, in which case making predictions is a fools errand. And therein lies the danger of predicting the future based on infinitesimally short data sets.

By choosing the period over which the data is analyzed, rain is either decreasing at 0.056" per year or increasing at 0.010" or 0.203" per year. That, dear reader, is exactly how climate alarmists achieve the desired result: manipulate the data! See Climategate: Ten Years Later
A little chicanery helps. Stephen Schneider — creator of the journal Climatic Change and one of the founding members of the UN’s Intergovernmental Panel on Climate Change (IPCC) — wrote in 1971 "It is found that even an increase by a factor of 8 in the amount of CO2, which is highly unlikely in the next several thousand years, will produce an increase in the surface temperature of less than 2°K." then said in 1989 "We have to get some broad-based support, to capture the public’s imagination. That, of course, entails getting loads of media coverage. So we have to offer up scary scenarios, make simplified, dramatic statements, and make little mention of any doubts we might have. This “double ethical bind” which we frequently find ourselves in cannot be solved by any formula. Each of us has to decide what the right balance is between being effective and being honest. I hope that means being both." [Emphasis added]

Annual Volatility

RainByYear

The graph shows rainfall by month from 1895 to present. There is no pattern or trend in year to year rainfall. The dotted lines are the average of the data and it can be seen that rainfall may be below average for several years and then ping-pong above and below. Or an exceedingly wet month can occur after a year of below average rain as occurred in December 2016, presaging the 2nd wettest year in Florence's history.


Historical Trends

“plus ça change, plus c'est la même chose”

RainTrends

A great many bits are committed to climate change.
The climate has always changed.
The climate will always change.
The graph averages monthly year to year change from 1895 to present in four periods. The legend caption is the last year of the period. While the period volatility is quite pronounced, the overall volatility is remarkably constant, up a very little, down a very little over a century and a quarter.


Prognostication

“...avoid prophesying beforehand because it is much better to prophesy after the event has already taken place”

- Winston Churchill

AnnualCorrelation
DepVsControl

A frequent topic of conversation is whether it's a wet or dry year and the likelihood of the current trend continuing.
The top graph shows the grouping of a control period and how it correlates with another period and a trend. A Positive slope means that the control period presages a similar dependent period, a Negative slope the inverse. The more tightly grouped the higher the correlation. Widely scattered points indicate a chaotic relationship.
The 2nd graph shows the same data in a linear format. In some periods there is a correlation and some none.

In Other Words, your guess is as good as mine.
