Temperature Discontinuities
-
I guess technically it's less error'd and more the vagaries of how High/Low temperatures are forecast. But seriously, guys, days are nice, continuous things, you
can'tshouldn't have these sorts of temperature discontinuities...
-
The low temperature usually only includes the part of the day after the high is reached. The forecast above says that tomorrow night will have a low of 11 even though the morning will be colder than that.
-
What, the swing from 5 F to -10 F? That's totally feasible. Hell, I'm fairly certain I saw both -10 F and +10 F in the same day a week or so ago, and I'm only in Pennsylvania. Same with going from 5 F as a high to 32 F as a high two days later...

What's the WTF here? What discontinuity?
-
If the highest temperature today (00.00-23.59 2/19/2015) is 5 degrees, and the lowest temperature tomorrow (00.00-23.59 2/20/2015) is 11 degrees, and the highest tomorrow is 13 and the lowest Saturday is 24, well, that's some really fast (not-so-Global) Warming right before midnight.
(And yes, I realize that's not actually what the forecast is "saying". But dammit, we're all nerds here, surely we can be overly pedantic about things like this!)

I've been burned on this before when trying to use the weather forecast to see if I need to plug in my truck's block heater or not. Now I look at the hourly and decide for myself what the low will be.
-
Forecasts are shit and leave 50 percent of the day out of the low calculation. They still do it that way because they've always done it that way and it would invalidate all their "records".

... and?

I guess I don't have that gene because I still don't see the issue.

Draw high / low lines by day. Notice that the ranges for each day don't overlap with the previous day. It's not that hard.

Right but as like 20 people here have explained, that's not how the "low" temperature is recorded. So the only way to consider this a WTF is to be utterly ignorant of what you're looking at, I guess?

You're not allowed to complain the next time someone ruins your joke like that.

So, I guess they recently changed how Hi-Lo temps are calculated...

That's a nice pink avatar, @blakeyrat.

Minima and midnight rarely coincide.

Agreed. I was harking back to this:

Oh, that takes me back… how things have changed…

Where is the automatic unit conversion bot? Some people actually obey the SI standards.

hmmm.... that's not one that's implemented.
i'll add it to the list.
-
Just make a Wolfram|Alpha bot.
-
Or use @MathBot

Oh, how the turn has tabled! Or something like that.
