Marine Weather and Tides
Brawley, CA

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Temperatures closer to seasonal normals will prevail through Monday
as high pressure has temporarily weakened. However, another warmup
will quickly materialize through the middle of next week with high
temperatures forecast to be near 110 degrees across the lower
deserts. A dry weather pattern will continue through late next week
as richer moisture remains fixed into mexico.

As shortwave energy over the northern rockies continues to dig
towards the central plains, a subtropical anti-cyclone center has
become further displaced equatorward over the central baja
peninsula. The forecast area has now become positioned along the
southern fringes of stronger northwest flow aloft; and 12z ktwc
sounding data sampled h5 heights some 4dm lower than Friday. As a
result, early afternoon temperatures were trending some 4f to 6f
cooler as the overall deeper thermal ridge relaxes.

Concurrently, the tightening synoptic pressure gradient has been
magnified by inland thermal low pressure facilitating a well defined
gulf surge early this morning. Over SE california and far sw
arizona, shallow mid 60 dewpoints persist and likely are making
upper 90 ambient temperatures feel even more miserable. Gusty
southerly winds have stirred up a few dust plumes (most evident
over mexico per goes-16 dust rgb composite difference channels)
adding to the magnitude of haze and air quality issues. Some mixing
of drier air aloft will cut into dewpoints later today while the
loosening of the synoptic and thermal gradients will allow winds to
slacken somewhat overnight. However, a more complete reversal to
these winds and moisture will probably not be accomplished until
Monday keeping air quality issues prevalent through much of imperial
county this weekend.

Through the middle of next week, a midtropospheric anti-cyclone will
quickly rebuild over the SW CONUS with models in excellent agreement
depicting central h5 heights near 595dm becoming reestablished over
eastern arizona western new mexico. The synoptic pattern and
forecast thermal profiles appear nearly identical to the spell of
hot weather earlier this week, and very similar temperatures are
forecast with many lower elevation areas almost certainly touching
the 110 degree mark once again. While current heatrisk output
suggests this will remain just shy of excessive heat thresholds,
these temperatures will still result in some heat-related impacts if
proper precautions are not heeded.

In what has remained a common theme thus far in june, the
climatologically favored anti-cyclone near the four corners that
typically supports prolonged periods of excessive heat will instead
be short lived as another upper trough develops over the western
conus. This will act to weaken the anti-cyclone and bring
temperatures back closer to seasonal normals by late next week,
while amplified ridging (and associated heat) becomes focused east
of the rockies. The operational ECMWF remains more progressive with
this western CONUS wave feature placing the region under predominant
wnw flow through the end of next week. However, naefs members give
far more support to a slower, deeper GFS solution which may be
sufficient to bring better quality moisture northward into eastern
arizona and new mexico. While the majority of the forecast area will
likely have to wait for the first taste of the active part of the
monsoon, there are inklings that this evolution could be the first
impetus to get more daily high terrain thunderstorms and outflows
rolling - perfect timing for the beginning of a new month.

South-central arizona including kphx, kiwa, and ksdl:
there are no major aviation weather concerns through tonight. The
winds this afternoon will maintain a westerly direction at 10 to 15
knots with a some stronger gusts before subsiding this evening.

Otherwise, clear skies and typical diurnal winds will prevail.

Southeast california southwest arizona including kipl and kblh:
the strong winds across the area will be of some concern through the
early evening. At kipl, wind gusts up to 15 to 25 kts will be
possible and at kblh wind gusts up to 20 to 30 kts will be possible
before subsiding early evening. Otherwise, clear skies will prevail.

Aviation discussion not updated for amended tafs.

Fire weather
Tuesday through Saturday:
temperatures will easily climb above seasonal normals by Tuesday
with midweek conditions very similar to the previous hot spell. Only
modest colling will take place by next weekend. Minimum afternoon
humidity values will fall back mostly into the single digits with a
return of poor to fair overnight recovery. No very strong winds are
expected next week, although typical afternoon upslope gustiness
will be common around terrain features. There will be a general
increase in daily wind speeds beyond the midweek time frame, but
nothing appraoching critical thresholds. There are still no signs of
rain through late next week.

Spotter information statement
Spotter activation will not be needed through at least the middle of
next week.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
