...New AVIATION, MARINE...

.SYNOPSIS...
Issued at 100 PM PST Mon Mar 4 2024

Unsettled conditions expected to persist through midweek, yet no
widespread flooding concerns. Warmer and drier weather finally
returns late week followed by a return to unsettled weather.

&&

.SHORT TERM...
(This evening through Tuesday)
Issued at 100 PM PST Mon Mar 4 2024

Rain showers have about all ended as of early this afternoon except
for the North Bay. Rain chances return to the North Bay later this
afternoon and into tomorrow as another short-wave trough approaches
the region. Rainfall amounts will be light and mostly beneficial.

Tomorrow will be slightly warmer across the Bay Area and more so
over the Central Coast and Santa Clara Valley. Temperatures will
range from the upper 50s in the North Bay to mid 60s across the
interior. Light rain will continue over the North Bay and may drop
as far south as the Santa Cruz Mountains.

&&

.LONG TERM...
(Tuesday night through Sunday)
Issued at 232 AM PST Mon Mar 4 2024

The low pressure system looks to come ashore somewhere along the
Central Coast on Wednesday, which may trigger a few stronger
showers. As the low continues to push inland, the southerly winds
will flip back to northerly as subtropical high pressure slides
into the driver`s seat. Thursday and Friday look to be the nicest
days of the week with clear skies, mild temperatures and a
moderate northerly breeze. The clouds and rain return with a cold
front expected over the weekend. The current guidance suggest rain
will be light to moderate, and mostly confined to the North Bay.
All rain this week looks to be mostly beneficial, with no
widespread flooding concerns.

Looking way ahead, ensemble guidance and the Climate Prediction
Center are both suggesting we will move out of this cold wet
pattern in mid-March.

.AVIATION...
(00Z TAFS)
Issued at 347 PM PST Mon Mar 4 2024

A disturbance over the Eastern Pacific is resulting in cloudy
skies across the region as well as light to breezy southwesterly
winds. As this low approaches the NorCal coastline tonight into early
Tuesday morning, VCSH will be possible across North Bay terminals
and OAK/SFO, but precip will be very light and unimpactful. VFR
is expected to persist with the exception of KSTS where reduced
cigs are more likely overnight tonight. Winds shift S/SE overnight
tonight, becoming light. SW winds increase again Tuesday
afternoon with sustained speeds of 8 to 12 knots expected across
the region.

Vicinity of SFO...Southwest winds of 10 knots expected to linger
at SFO through at least 04z before turning more southerly and
reducing into the overnight hours. Light SE winds expected early
Tues morning before SW winds increase again by the afternoon
hours. VFR is expected to persist through the TAF period with
cloud decks potentially reaching 3500 feet overnight into early
Tues morning during periods of light, sporadic rain.

SFO Bridge Approach...Satellite imagery shows cumulus deck around
3500 feet is starting to scatter out over the bridge approach.

Monterey Bay Terminals...Breezy NW winds with VFR conditions.
Winds shift SE overnight tonight, becoming breezy across the
Salinas Valley by early morning. Winds shift SW/W tomorrow
afternoon.

&&

.MARINE...
(Tonight through next Saturday)
Issued at 347 PM PST Mon Mar 4 2024

Generally benign marine weather conditions as the moderate period
northwesterly swell continues to diminish. Shower activity will
increase in coverage Tuesday through Wednesday as a low pressure
system approaches from the Pacific. As this low pressure system
approaches, winds will shift to become a moderate southwesterly
breeze. Northwesterly winds will increase Thursday through the
coastal waters, which will result in elevated seas.

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 World Extremes

This script was originated by Michael of Relayweather.com and has been rewritten to use the NWS Climate Prediction Center's CSV file for world observations. 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 variables:

$omittedCountry (text list of countries excluded from $world high/low/precip scans)
Note: the setting $ignoreCountrys is the array of country names to to exclude
$worldhigh
$worldlow
$worldprecip

$selectedCountry (setting: country name for selected country high/low/precip)
Note: run http://your.site.com/worldextremes.php?list to see the list of country names to use
$countryhigh
$countrylow
$countryprecip

$usahigh (Note: for lower-48 USA states)
$usalow (Note: for lower-48 USA states)
$usaprecip (Note: for lower-48 USA states)

$selectedState (setting: USA state 2-character name abbreviation in settings area)
$selectState (a copy of $selectedState for compatibility with old stateextremes.php)
$statehigh
$statelow
$stateprecip

$reportDate (nicely formatted date of the report)
$stateReportDate (a copy of $reportDate for compatibility with old stateextremes.php)

You can run the script by using:

<?php
include_once("worldextremes.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 courtesy of <a href=\"";
print "https://www.cpc.ncep.noaa.gov/products/cadb/";
print "\">NWS-CPC</a></small></p>\n";

?>

which produces this result (with live data):

USA Extremes for Sunday, March 3, 2024

High Temperature

94°F at Jesse Viertel Memorial Airport, MO

Low Temperature

-13°F at Mike (moore), MT
-13°F at Stanley Ranger Station, ID

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.

$cacheFileDir = './'; // directory to store cache file in.
$cacheFile2 = "worldextremesCache.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 (display in C is default)
$rUOM = 'in';     // or ='' for no rain unit display (display in mm is default)
#
$ignoreCountrys = array('Antarctica','Greenland');     // for world extremes - exclude these country(s)
$ignoreStations = array('99KLRJ');     // list of stn_id (field 0) to ignore for bogus data
$tempDiffAllowed = 40; // max difference Tmax-Tmin (C) for valid data
$selectedCountry = 'Canada'; // for country max/min/precip in $country* variables
// note: the $usa* variables will have the min/max/precip for the lower-48 states
$selectedState   = 'CA';  // for USA state max/min/precip in $state* variables

Note that $cacheFileDir, $tUOM, $rUOM will use the Saratoga template Settings.php values if used in a Saratoga template.
