Area Forecast Discussion
National Weather Service San Francisco Bay Area
1049 PM PDT Wed Jun 26 2019

.SYNOPSIS...Unseasonably cool conditions will persist over the
region through late week with periods of night/morning low clouds
and breezy onshore winds. A slight warming trend is then forecast
for the upcoming weekend along with continued dry weather
conditions.

&&

.DISCUSSION...as of 9:53 PM PDT Wednesday...Low clouds are seen
redeveloping along the Sonoma county coast to northernmost Santa
Cruz county with fragments of low clouds elsewhere.

A sprawling upper low remains located off the Pacific Northwest
and cooler air continues to flow into northern California on
northwest winds. Low clouds should mix out again Thursday with a
fair amount of sun for the day, afternoon onshore winds picking up
again; the short term forecast is near persistence. Over the
weekend temperatures will warm up particularly over inland
valleys.

&&

.AVIATION...as of 10:45 PM PDT Wednesday...Clouds scattered for a
short time after 00Z but more clouds just kept developing to the
northwest and it looks like SFO and the approach will be under
cigs through Thursday morning. Clearing should be early Thursday
as drier air is forecast to work its way down into the lower
levels.

Vicinity of KSFO...MVFR cigs through 17Z. Bases 1500-2000 feet
lowering to 120.

SFO Bridge Approach...Same as KSFO.

Monterey Bay Terminals...Clouds cleared out and are slow to
redevelop. There have been occasional cigs but more widespread
MVFR cigs are expected after 09Z.

&&

.MARINE...as of 10:10 PM PDT Wednesday...Low pressure off the
Pacific Northwest will move inland on  Thursday. High pressure
will then build off the California coast resulting in increasing
northwest winds Thursday and Friday. Winds should decrease
Saturday as the high weakens.

NWS MTR Office Area Forecast Discussion

To use, include the output of the script on your webpage by using

<?php
$doIncludeFD = true;
include("forecast-discussion.php"); ?>

to perform the include. Settings inside the script are:

// settings:
//  change myNWS to abbreviation for your local NWS office
//    other settings are optional
//
    $myNWS = 'MTR';   // San Francisco, NWS office
//  $myNWS = 'PQR';   // Portland, OR
//  $myNWS = 'OAX';   // Omaha, NE (Carter Lake, IA)
//
$cacheName = "forecast-discussion.txt"; // used to store the file so we don't have to // fetch it each time $refetchSeconds = 1800; // refetch every nnnn seconds
$cacheFileDir = './'; // default cache file directory // end of settings

The only required setting is for $myNWS which designates the local NWS office.
To find the 3-character abbreviation for your local NWS office for the $myNWS variable, follow these steps:

  1. Browse to www.weather.gov
  2. Use the search box on the left to search for your city, state
  3. Look at the URL in the 'Forecast Discussion' link near the bottom of the page
  4. Use the 3-character abbreviation is in the &issuedby=XXX parameter on the Forecast Discussion link (XXX will be your local office)
  5. put the XXX in the $myNWS = 'XXX'; statement

The script has two optional parameters when you call it by URL from your website::

inc=Y
Will return the contents without the surrounding <html><head></head><body> and </body></html> tags
cache=no
Will override the default $refetchSeconds=1800 so that the cache is refreshed immediately

PHP for NWS CPC USA Extremes

This script was originated by Michael of Relayweather.com and has been rewritten to use the NWS Climate Prediction Center's One Day Old Daily Data Summary text file for the USA. The script does not produce output (other than HTML comments for status), so you are free to include it in a page, and format the text output as you desire. The script returns data in four variables:

$usahigh - contains the text of the high temperature station(s) (value and station name from the NWS)
$usalow - contains the text of the low temperature station(s) (value and station name from the NWS)
$usaprecip - contains the text of the high precipitation station(s) (value and station name from the NWS)
$reportDate - contains the text of the date for the report (default format is 'Dayname, Month day, Year')

You can run the script by using:

<?php
include_once("usaextremes.php");

print "<p>USA Extremes for $reportDate</p>\n";
print "<p>High Temperature<br/><br/>$usahigh</p>\n";
print "<p>Low Temperature<br/><br/>$usalow</p>\n";
print "<p>High Precipatation<br/><br/>$usaprecip</p>\n";
print "<p><small>Data courtsey of <a href=\"";
print "http://www.cpc.noaa.gov/products/analysis_monitoring/cdus/prcp_temp_tables/";
print "\">NWS-CPC</a></small></p>\n";

?>

which produces this result (with live data):

USA Extremes for Tuesday, June 25, 2019

High Temperature

105°F at Phoenix/Sky Harbor Int, AZ
105°F at Needles Airport, CA

Low Temperature

Data courtsey of NWS-CPC

The script has internal settings which you can adjust. If run in a Saratoga template, the cache file will be stored in the ./cache/ directory based on $SITE['cacheFileDir'] in Settings.php.

// Site to Parse
$url2 = "https://www.cpc.ncep.noaa.gov/products/analysis_monitoring/cdus/prcp_temp_tables/dly_glob1.txt";
// Name of cache file  --  This file must be set to CHMOD-666
$cacheFileDir = './'; // directory to store cache file in.
$cacheFile2 = "usaextremesCache4.txt";  
// Age of cache file before re-fetch caching time, in seconds (3600 = 1 hour)
$cache_life = '3600';
$reportDateFormat = "l, F j, Y"; // Day, Month d, yyyy 
$tUOM = '&deg;F'; // or ='' for no temperature unit display
$rUOM = 'in';     // or ='' for no rain unit display
$ignoreStations = array('99NRB'); // Station numbers to ignore, Array of station numbers
