Rain or no rain, WIndy shows conflicting info?
-
It seems there is an issue with the 1h/3h view. See attached, wed 14:00 one time it rains, next time it doesnt?

Please read https://community.windy.com/topic/13690/ecmwf-1-hour-vs-3-hours-in-bassano-del-grappa-italy?=1616009247860
for explanation.
Practicaly those amounts are "traces of rain"

@Gkikas-LGPZ Thanks for clarification. That makes sense. Is there also a way to get rain probablity shown? weathermodels usually come with it and websites also show it, but windy seems not to have that function?

@KHNOH
Windy don't show (yet) probability charts.
And I'm very sceptical for the usefulness
as the interpretation would be sometimes tricky.How do you interpret probability 12% for rain?
12% of 0.2mm/3hr is the same with 12% of 50mm/3hr?
Of course not!What about 5% of 1mm/3hr, 50% of 0,2 mm/3hr and 90% of 0.1mm/3hr?
Will you take an umbrella with you? -
@Gkikas-LGPZ concerning the practicability it would seem to me more useful in a general sense. 15% chance oof some rain? I would go to the flying area. 75%? Imay rethink, 90%, I d make alternative plans. Especially when it comes to travelling it may help

A way to estimate the uncertainty of the forecast in Windy is to check the “Compare forecasts” table, below the point forecast panel. If all models show a similar prediction there is a good chance that the event occurs.
