Observations vs Forecast is broken -- at least for me?!

mrpetewx

I've used this feature in the past (a few years ago.) It appears that at the very least, the UI has changed significantly since the instructions were written ( https://community.windy.com/topic/9425/how-to-use-the-observation-vs-forecast-feature. )

Anomalies I am observing, and a few questions/suggestions:

A) Select Reported Wind and a model.

Most stations disappear (ie almost ALL) Even though they have plenty of wind reporting.
Stations not reporting a current non-zero windspeed disappear. BUG?
CANNOT select a time frame
No comparison(s) show up

Much preferred the UI where all models are graphed. Oh well.

Suggestion/Question
B) I would LOVE it if we could compare much more than reported wind speed!

Temperature of course
But even more, for where we live (7000 ft in Colorado USA)... precipitation! Both rainfall and SNOW. Who is accurate about snow?

Suggestion/Question
C) Without information re the prediction timeframe, this feature is almost useless. Example: the HRRR model is updated SO frequently for the near future, that of course at TOBS (Time Of Observation) it is "correct". A real example:

Last night we had ~~ 8.5-9 inches of snow.
Yesterday noon, HRRR was predicting a total of ~~2.5 inches in the following 24 hours. All other models ranged 4.5 to 9-10 inches.
Over the 24 hr timeframe, HRRR "predictions" kept changing. What a surprise (not): the "predictions" at TOBS were about right.

Same is true for other models. So...

Suggestion: add a dial to the feature, allowing the user to select how far in advance the models should be evaluated. Perhaps a 24 or 36 hour default?

Selecting Reported wind I get these weather stations in Colorado.

You said “most disappear”… compared to what number ?
Selecting Reported temperature display the same weather stations.

Then you just need to select a weather station and Observation vs forecast.

By the way, since the 2019 article you are referring to, the way this feature is used has changed.
