The Zambretti Weathercard Forecaster

Edit 2/15/2013 2:37 PM CST:

The attached zambretti.zip file has been updated.

-----

I came across one of these.  It uses 950-1050 hPa, wind direction, summer/winter, and rising/steady/falling just like the Zambretti Forecaster.  It, however, uses different forecast names and has 27 forecasts.

Here are the forecasts which use numbers (no letters):
1) Stormy, Much Rain
2) Very Unsettled, Much Rain
3) Very Unsettled, Rain
4) Rain At Frequent Intervals
5) Unsettled, Rain At Times
6) Changeable, Some Rain
7) Rain At Times, Fine Intervals
8) Local Showers, Fine In Between
9) Fine, But Tendency To Local Showers
10) Fine Generally
11) Fine Over A Large Area
12) Settled Fine Weather
13) Stormy, Temporarily Better
14) Very Unsettled, But Some Improvement
15) Very Unsettled, Becoming Finer
16) Unsettled, But Improving
17) Some Rain, But Improving
18) Ran At Times, Becoming Less
19) Occasional Rain, But Improving
20) Some Showers, But Improving
21) Rather Unsettled, But Improving
22) Fine As A Whole And Improving
23) Fine, Becoming More Settled
24) Some Rain, More To Follow
25) Changeable, Some Rain, Worse Later
26) Showery, Becoming More Settled
27) Rather Unsettled, Local Showers

If Rising, it goes:
13, 13, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 10, 11, 12, 12, 12, 12, 12

If Steady, it goes:
1, 1, 1, 1, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 12, 12, 12, 12

If Falling, it goes:
1, 1, 1, 1, 1, 1, 1, 3, 3, 24, 5, 25, 26, 27, 23, 10, 11, 11, 12, 12

Using Beteljuice's work for the Zambretti Forecaster, I updated it as best I could to use the Zambretti Weathercard Forecaster instead.  It seems like it works so far.  The zip is attached to this post.

Personally, these forecasts seem to be more accurate, but I am still experimenting.

Beteljuice, the creator of the original Zambretti Forecaster Algorithm, has been helping me with this over on the official Cumulus forum:
