I did see this, but I am curious what barometer pressure triggers what forecast...
http://wiki.sandaysoft.com/index.php?title=Strings.ini
The reason I ask is because I have an older Taylor Stormoguide barometer I have grown quite fond of and it has forecasting on it. Here is what it uses...
IF RISING...
28.50 - 28.19 = High Winds & Cooler
28.20 - 28.69 = Continued Winds & Cloudy
28.70 - 29.19 = Winds & Cool
29.20 - 29.79 = Fair Next 24 Hours
29.80 - 30.29 = Winds & Fair
30.30 - 30.79 = Fair Probably Cool
30.80 - 31.50 = Clear, Continued Cool
IF FALLING
31.50 - 30.80 = Fair & Warmer
30.79 - 30.30 = Cloudy & Warmer
30.29 - 29.80 = Unsettled
29.79 - 29.20 = Winds & Rain
29.19 - 28.70 = Stormy
28.69 - 28.20 = Very Stormy
28.19 - 27.50 = Tornadoes & Hurricanes

Re: Change Forecast Names / Words / Phrases
Cumulus uses a software implementation of the Zambretti Forecaster. I stole the algorithm from beteljuice (a forum user). You can find his javascript in use in many places on the web, e.g. here: http://www.whitbyweather.com/Zambretti/forecaster.html

Re: Change Forecast Names / Words / Phrases
Yes .. rather worryingly (after they proudly sold their software) they revised their description after this forum pointed out W / S meant Winter or Summer, but their reasoning said Weak / Strong 
The pressure tables are near enough, but remember the forecaster does modify these according to wind direction and season.

Re: Change Forecast Names / Words / Phrases
Yeah I doubt I would ever be able to get it just right using the Taylor Stormoguide barometer phrases. That's OK though as I was unaware of the Zambretti Forecaster and how detailed it is.
I went ahead and updated the wording using the link I posted to the 2000 model and added commas where needed. I also updated the line for hurricane to Hurricane=Tornado/Hurricane as I am way inland so I never have hurricanes but certainly do have a tornado from time-to-time.
If anyone wants to try it, save the attached file to the Cumulus folder then restart Cumulus. To revert back to the 1915 wording, either rename or delete the attached file then restart Cumulus.
