Topic: more 10-day weirdness

[danxx]

A few weeks ago I saw that the hi/low temps listed in the 10-day forecasts only roughly corresponded to the plotted values. Now I notice that the hi/lo for a given day doesn't even correspond to that day. The hi/lo for one day seems to correspond to the hi for that day and the lo for the next. See image below, where hi/lo for Tuesday is 93/61F, but the 61 actually comes (only roughly, one remembers) from Wednesday. So the low temp for Tuesday actually happens on Wednesday morning. Data management is not a strong point for the WU folks, I gather.

I remember a lot of extended forecasts  on tv, would do it that way ( the low for a given day was actually for the next  morning ) I've seen it done that way for a long time...Don't know if it's still done that way  but I remember how it drove  me nuts.

I think you're right. I've seen this before. But it's kind of bizarre, where the low temperature of today happens tomorrow.

[catdon]

Yeah could never understand the logic.

It is a forecast.  High is for the day and low is the overnight low.  Why would you put the low that had already occurred in a forecast?  Just my $.02.  Makes sense to me.

It's supposed to be the hi/lo for ONE DAY. You don't make the hi for one day and the lo for the next if you list it that way. If you listed it differently, it might make sense. But it doesn't the way it is. I'll call it $0.05.

Pretty much same way NWS forecast looks.  I couldn't care less what the low temperature for today was in a FORECAST, I want to know what the overnight low is GOING to be.

Whatever.

The ten-day forecast looks ahead ten days. That's what we're talking about here. We're not talking about what the lo was today. This is telling me that the lo next Tuesday really happens on Wednesday. $0.10.
