I also wonder where these forecasts come from? Clicking at the link where it shows "Powered by Forecast," it takes me to the Dark Sky site, but even there, the forecasts are a bit different from what shows on my MyAcurite dashboard page.
It seems odd that in the 4 months since these questions were first posed, nothing has changed.
FYI, the forecasts on the MyAcurite page have been a little closer to accurate than those found on the Wunderground page.
Looked at the 36 hour forecasts today. Noticed that they are completely off base re: temp, as others have said. Winds may agree with the NWS.
Laurie B....Regarding location.... I just compared the 5 day forecasts from my MyAcuRite dashboard, darksky.net at location that pops up when clicking on forecast.io, darksky.net when resetting location at top of its page to my address (which gets me about 6 miles from the my actual location), and the NWS as a 'point forecast' centered on my location. Winner seems to be NWS, then my dashboard but only temperature wise. darksky.net is way 'out to lunch'! NWS says no rain all this week,; dashboard and darksky.net say rain W, Th, Fri.
I also agree that Wunderground is bogus. Folks that have stations in my area that share appear to have their barometers set to 'auto' vs. 'manual'. Pressure readings are about 3.00 in. Hg high. (Been there, done that). Wunderground stations seen on home page for the 'greater XXX area' are a repeat of the NWS main stations.
With all this, I do not have a clue where the forecasts come from. Maybe a mixture of everybody plus the Weather Channel? Russian hack job?
Acurite: Showing the forecast on the 6's isn't helpful. It would be helpful to know, sometime in the morning, what the high is expected for that day. So, if I'm checking the forecast at 6am, I'd like to know what that day's high might be (what clothing do I want to wear, should I go for a hike, or plan to stay indoors). Knowing the possible temp at 6 am, 6 pm, and 6 am the next day just isn't helpful in that regard. Can you get this changed?
I know that every locality will be different, and pinpointing a forecast to a specific spot may be too much to expect. For me, it's just for fun. I in no way pretend to be a forecaster and my stats don't really matter to anyone but me.
