Marine Weather and Tides
Cedar Hill, TX

Version 3.4
What's New / NOTES
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

vfr conditions are expected to prevail through the period with
southerly winds around 10 kt. Can't rule out an isolated shower or
storm mainly east of the major airports today, but coverage will
only be about 10%. Other than some passing high clouds, no major
aviation concerns are expected through the period.

today and tonight
upper ridging will strengthen across the region today ahead of a
westward moving upper trough over the gulf of mexico. This should
result in a hot but mostly dry day across north texas with high
temperatures near 100 degrees and rain chances generally less than
10%. A little better mixing of the low levels is expected this
afternoon which should result in dewpoints falling into the mid to
upper 60s. The only exception will be across our far eastern
counties where the best moisture will be located today. This is
where we'll have some low pops this afternoon for isolated
thunderstorms. Similar to yesterday, any convection could produce
some gusty outflow winds and locally heavy rainfall. Otherwise,
most areas will stay mostly sunny today. With slightly drier air
near the surface, heat indices will generally range between
102-105 degrees, so no heat advisory is needed for today. Any
isolated convection will diminish by this evening with mostly
clear skies expected overnight.


Long term issued 345 am cdt Sun aug 20 2017
Monday through Saturday
Monday should feature generally tranquil weather as north and
central texas remains sandwiched between two primary high
centers. Residual low-level moisture present across our far
eastern and southeastern counties may be sufficient to allow a
couple showers storms to bubble with the peak heating of the day.

Heat indices once again appear too marginal and limited in areal
extent to justify a heat advisory at this time, but pockets of
104-106 degree readings are possible. For those hoping to get a
glimpse of the partial eclipse during the early afternoon (with
the aid of proper eye protection, of course), mother nature looks
to cooperate as just spotty daytime cumulus dots the sky.

Attention on Tuesday will begin to shift to the north, as a cold
front slides into oklahoma. While pressure rises and cold
advection behind this front don't look to be overly impressive,
guidance continues to suggest that plentiful thunderstorm coverage
and associated cold pool amalgamation may help drive this boundary
across the red river as early as Tuesday evening. On the flip
slide, the GFS and its associated ensemble guidance continues to
be the laggard of the global guidance, introducing the front to
our northern counties on Wednesday night. Considering the
consistency shown by the ecmwf, cmc, and now backed up by the nam,
we've introduced chance pops north of i-20 Tuesday evening, and
likely pops near the red river overnight as activity leaks south
of the state line. The overall threat for severe weather during
this time frame appears low right now given pretty lazy mid-
tropospheric flow (20 kts or less) and a lack of better mid-level
lapse rates.

We'll continue chance pops across much of north and central texas
into Thursday, but it appears that dry air will persistently work
its way in from the north and east through this period, which may
temporarily bring precip chances to an end across our northern
counties Thursday night.

Overall, rainfall totals during the Tuesday night through
Thursday night portion of the forecast aren't exceptionally high,
and this seems to be tied to a lack of more widespread and focused
forcing aloft. It's possible that ripples embedded within the
northwesterly flow act to locally enhance storm coverage--and
therefore precipitation amounts--but any hope of capturing these
finer-scale details at this range is wishful thinking. Given weak
steering flow and high moisture quality content, individual
storms will certainly be capable of laying down impressive
rainfall rates, but their coverage looks to remain isolated enough
to temper the overall flood risk. Record summertime rainfall
amounts across our northeastern counties means locations north and
east of the metroplex will remain the most vulnerable to
additional deluges, however, and this is something we'll keep in
mind over the coming days.

The highest precipitation chances (30-40%) will migrate generally
west of the i-35 corridor towards week's end as drier air
continues to spill in from the northeast. Thanks to the increased
cloud cover and precipitation, temperatures by Thursday will
be pretty refreshing. Have indicated highs in the mid to upper
80s across most of the region, but if widespread storms and cloud
cover persist through the day, these may even be a touch too warm.

These have not been checked for accuracy and in many cases have not even been read by anyone associated with I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. 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.
