The announced changover date for forecast.weather.gov is still 7-Mar-2017 and it has a lot of changes.  The forecast-v3.weather.gov site (preview NWS site) shows what the new site will look like.

For we who operate personal weather websites that use my advforecast2.php script, be aware that the coming changes will make V4.x of the script NO LONGER WORK as they have removed the /MapClick.php?... functionality of the forecast.weather.gov website in favor of a new request mechanism.

I've put together advforecast2.php V5.00 as a fairly complete rewrite of the prior script.  It now uses the api.weather.gov website to retrieve JSON data for point-forecasts, zone forecasts and the needed metadata about both.
I'm not going to release the update via my usual channels (script page and Saratoga template Updates tool) until AFTER their cutover is done, but... you can make your USA website ready by installing the contents of the attached zip file.

Here's the README file included with the .zip file that helps explain what's changed:

Code: [Select]
This is the updated support package for version of advforecast2.php V5.00 - 06-Mar-2017

The advforecast2.php V5.00 uses the new NWS api.forecast.gov to retrieve JSON data and construct the forecast
display, so it differs from all prior versions (which used page scraping of the point-printable
forecast).

Since the new forecast.weather.gov website uses a different method to specify the point forecast,
the script includes auto-conversion of old-format point-printable forecast URLs to the new
format required.

As of 6-Mar-2017, the api.weather.gov alerts query returns only alerts of types:
Advisory, Watch, Warning and Statement.
The Outlook type alert is NOT currently included in the feed.
That may change in the future, but be aware that "Hazardous Weather Outlook" will not be displayed.

New with this release:

Improved diagnostics (available with ?debug=y on the URL) as HTML comments on the page
Improved cURL-based fetch for all data from api.weather.gov

cache files for the script have new (but related) names:
./cache/forecast-{Zone}-{n}-json.txt  contains the forecast data for the point or Zone
./cache/forecast-{Zone}-{n}-json-alerts.txt  contains the alert data for the Zone
./cache/forecast-{Zone}-{n}-json-meta.txt  contains the metadata about the point, Zone and WFO

New icon template file:
./forecast/icon-templates/nsmoke.png   (nighttime smoke image)

New icons with PoP stamps:
./forecast/images/cold[0..100].[jpg|png]  daytime cold w/PoP stamps
./forecast/images/ncold[0..100].[jpg|png] nighttime cold w/PoP stamps

DualImage.php V1.01 - 06-Mar-2017 supports the modified/new icon names from the NWS

advforecast2.php V5.00 - 06-Mar-2017 has additional new features:

setting addition:
$showTwoIconRows = true;   // =true; show all icons, =false; show 9 icons in one row (new V5.00)

If =true;, then two rows of up-to 9 columns of icons for day and night icons are shown
If =false;, then the original style of one row of 9 icons are shown.

running advforecast2.php?convert will display the the converted new-format point forecast URLs and
other settings needed.  If run on a site with a Saratoga template, the $SITE[] settings for Settings.php
will display, otherwise, the internal settings needed for advforecast2.php itself will be displayed.

I'm sure there will be additional updates as the new forecast.weather.gov settles in.

My thanks to the brave beta testers of the advforecast-json.php script!  That script is now named advforecast2.php for backward compatibility reasons.

Well, their prior implementation date was today (7-Mar-2017).  Now the forecast-v3.weather.gov site shows

Notice of NWS' New Version of Forecast
A new version of Forecast will launch April 4, 2017.

So 4-Apr-2017 is the new must switch to the JSON advforecast2.php to retain your USA NWS forecasts.

I'll do the "official" release of the code for standalone and Saratoga templates on the date the NWS actually updates forecast.weather.gov with the new site design.  Meanwhile, you're still most welcome to play with the script.  Keep in mind that the NWS developers are fairly constantly modifying the api.weather.gov and forecast-v3.weather.gov sites, and no 'Outlook' type alerts are yet available via the API.  The forecast text is somewhat funky too (Heat index... and Wind-chill... messages on some forecasts ?!?)

If you're interested in following the main discussion about the script, please drop by WXforum.net thread to report bugs, etc.
