Forecast Question - Expected Rain

[cweakland]

I have my Belchertown skin up and functioning and I am using DarkSky for my forecast information. Is there a way to show the foretasted rain amount? I have seen screenshots of it being done for snow fall, but my rain just displays a percentage of probability.

Thanks,
Chris

Hi Chris you have to modify the jQuery to display rain amount.
On my skin I show the amount only if the probability is more than 20%
For the 1 hour forecast, Replace

weewx-belchertown/skins/Belchertown/js/belchertown.js.tmpl

Lines 1341 to 1345 in 026619d

	} else if (forecast_row[i]["precip"] > 0) {
	output_html += '<i class="wi wi-raindrop wi-rotate-45 rain-precip"></i> <span>' + parseFloat(forecast_row[i]["precip"]).toFixed(0) + '%</span>';
	} else {
	output_html += '<i class="wi wi-raindrop wi-rotate-45 rain-no-precip"></i> <span>0%</span>';
	}

                        output_html += '<i class="wi wi-raindrop wi-rotate-45 rain-precip"></i>';
                        if (forecast_row[i]["precip"] > 20) {
                            output_html += '<span> ' + parseFloat(forecast_row[i]["precipMM"]).toFixed(0) + ' mm</span>';
                        } else {
                            output_html += '<span> ' + parseFloat(forecast_row[i]["precip"]).toFixed(0) + '%</span>';
                        }
                    } else {
                        output_html += '<i class="wi wi-raindrop wi-rotate-45 rain-no-precip"></i> <span>0%</span>';
                    } 

and For the 3/24 hour forecast, Replace

weewx-belchertown/skins/Belchertown/js/belchertown.js.tmpl

Lines 1387 to 1391 in 026619d

	} else if (forecast_row[i]["precip"] > 0) {
	output_html += '<i class="wi wi-raindrop wi-rotate-45 rain-precip"></i> <span>' + parseFloat(forecast_row[i]["precip"]).toFixed(0) + '%</span>';
	} else {
	output_html += '<i class="wi wi-raindrop wi-rotate-45 rain-no-precip"></i> <span>0%</span>';
	}

                    } else if (forecast_row[i]["precip"] >= 20) {
                        output_html += '<i class="wi wi-raindrop wi-rotate-45 rain-precip"></i> <span>' + parseFloat(forecast_row[i]["precip"]).toFixed(0) + '%</span>';
                        output_html += '<span> | ' + parseFloat(forecast_row[i]["precipMM"]).toFixed(0) + ' mm</span>';
                    } else {
                        output_html += '<i class="wi wi-raindrop wi-rotate-45 rain-no-precip"></i> <span>0%</span>';
                    }

Note that is for Aeris forecast but should be the same from Darksky, check your forecast.json for precipMM.

Hello,
I get NaN mm displayed in the prediction. Is there anything else that needs to be changed? I have precipMM in Forecast.json .

Thanks
