Thread: Spikes and dips in hourly forecast

Started 1 year, 5 months ago by JimsEvilTwin
Since installing v2.0.8, I've started noticing severe dips or spikes in my hourly forecasts. I didn't think much of them at first since it was happening sporadically. I figured something was off in the reporting from the source of my home location (Dallas). This was until I caught a look at my Weather Console in the middle of an update for another location (my test city of San Francisco) ...

benkc, thanks for your response. QUOTE(benkc @ Jul 16 2008, 01:53 PM) I see dips in a rising hourly trended graph quite frequently and it appears to correspond to the forecast source. You can check this by comparison with your source on the Internet. What does confuse me is why your hourly report has an 11:45 & 12:15 row. I have never seen other than top of the hour reports. ...

QUOTE(JimsEvilTwin @ Jul 17 2008, 07:28 AM) I setup my PW locations using default settings. How do I lookup the corresponding internet source? Several ways to look up the source data on the Internet. For more advanced users, one can look at the update debug log (PW_upd.tx - if debugger is enabled in PW Options->General->Debug) and see the actual URLs used by PW for each type of...

QUOTE(Psi Phi @ Jul 17 2008, 10:38 AM) I've noticed this too... Seems like it is tied to a certain time of day for me... My hourly rain prediction often will spike or dip around 7pm if there is a lot of variation on the percentages during the day... I have seen it on the temperature prediction too, but not so often... I almost want to say an optional filter needs to be built that ...

QUOTE(benkc @ Jul 17 2008, 03:32 PM) Can you post a screen shot of the "hourly rain prediction" ? I was not aware that this was repaired yet. One can get daily rain predictions, hourly humidity forecasts, and previous rainfalls. And yes, a filter or operand to average several values would be most appreciated -- but in the meantime, there are ways around this by combining bar ...

QUOTE(Psi Phi @ Jul 18 2008, 02:56 PM) Ah, found a location with problems in both graphs... sshot004.PNG ( 64.11k ) Number of downloads: 0 My biggest issue was finding a source to scrape prediction data from and writing the script... I use the Weather Channel and have used the script since 2.0.6... Oddly, the numbers match up with the site ( http://www.weather.com/...

QUOTE(benkc @ Jul 18 2008, 08:48 PM) Thanks for the sreen shot. If you attach the image in any format BUT bmp, it will display. So you wrote a "custom weather source template" to scrape the data from a Weather Channel page. I thought Jenny wrote several weather.com scripts for multi-day forecasts, hourly fourcasts, and current conditions that seemed to work pretty well. I also ...

Haven't chimed in for a while..... Had to hard-reset my PPC over the weekend due to other issues. The bad news is despite the reset and complete re-installation, my spike/dip problem persists. I may be using a custom layout, but I don't think that's the source of the problem. Here is the "Detailed" Weather Console layout, alongside my layout's graph. DFW_Detailed.png ( 120.97k ) ...

Is there a way to change the order of updates programatically? If the Current data is updated 1st, then the Forecast data 2nd, the Temp forecast graph problem pretty much disappears... I've tested this by manually via updating All Current, after which I did All Forecasts... (Still have issues with Rain forecast graph though...) Thanks

Depends on which unit you choose : 37? F => 2.77? C (water comes into ice at 0?C) but 37? C => 98.6? F So, boiled or frozen ?

From a quick look, I can see that (at least in my configuration) those spikes always seems to be located around midnight, and that the local value at the midnight spike exactly mirrors the local value at *noon* the next day! So this would indicate the interpreter might somehow confuse the values retrieved for 12am with those for 12pm... (used to 24 hr time format, I find this am/pm thing pretty confusing too ;
