Aviation
Winds have been slowly veering through the night, and are expected
to be out of the south across the CWA after midnight. The storm
complex which was over the trans-pecos valley produced substantial
high clouds, and with the upper level flow from west to east, a
few high clouds will continue to stream in through the night.

A surface high centered over louisiana will strengthen through the
day tomorrow, leading to southwesterly winds at both dfw TAF sites
and kact. Wind speeds should remain between 5-10 kts through this
taf cycle. Afternoon cumulus clouds should develop as daytime
heating and abundant moisture allow for parcels of air to rise.

There will be a chance for isolated showers and thunderstorms,
mainly across the dallas fort worth TAF sites. There is no
mention of thunder at any of the TAF sites due to the low
confidence in occurrence and location of any storm that does
develop. This trend will be monitored through the night and
amendments will be made if necessary.

Update issued 957 pm cdt Fri aug 18 2017
the main change to the forecast through early Saturday morning
was to decrease the probability of precipitation to near zero
across north and central texas. Model guidance through the
afternoon had suggested at a chance of showers and storms clipping
the northeastern zones as a cluster of storms moved southeast
through eastern oklahoma and southwestern arkansas. Initiation
across oklahoma did not occur, therefore, rain chances have
greatly decreased. Low temperatures across the dallas fort worth
metroplex will be in the upper 70s, with mid 70s elsewhere.

Short term issued 357 pm cdt Fri aug 18 2017
tonight
scattered showers and thunderstorms developed across north texas
this morning along and north of i-20 this morning. Development of
these storms occurred in a band of mid-level moisture and were
then aided by an outflow boundary that pushed into the region from
oklahoma. Temperatures this afternoon were quite dependent on
cloud cover, convection and outflow boundaries. At 3 pm,
temperatures ranged from mid 70s to mid 80s in area in and near
where it was raining to the upper 90s across central texas where
there was abundant sunshine.

Expect scattered showers and thunderstorms to continue into the
evening mainly along and north of i-20. This activity will wane
through sunset. Depending on development of thunderstorms over
oklahoma tonight, there may be a slight chance of thunderstorms
late tonight across our northeastern zones... Northeast of a
sherman to sulphur springs line. Winds will be southerly at 5 to
10 mph with lows in the 70s.

Long term issued 357 pm cdt Fri aug 18 2017
Saturday through Friday
there will be a 10 to 20 percent chance of thunderstorms across
all but central texas Saturday with the best chances across the
northeastern zones. An upper level ridge will try to build in late
Saturday through Monday. This should confine low rain chances to
areas east of the i-35 corridor Sunday through Tuesday.

Temperatures should be slightly above seasonal normals with highs
in the mid 90s to near 100 degrees and lows mostly in the 70s.

Upper level heights should start to fall late Tuesday as the
ridge shifts westward and a shortwave moves across the northern
and central plains. This will allow a cold front to move down the
plains and into north texas on Wednesday. The models differ on how
they handle the front with the GFS stalling the front north of
the i-20 corridor while the ECMWF moves it into central texas.

Either way, we should have a 30 to 50 percent chance of showers
and thunderstorms Wednesday and Thursday with lower chances on
Friday. With the increased cloud cover and chances of showers and
thunderstorms, highs will be a few degrees cooler with upper 80s
to mid 90s expected.

It is not checked for accuracy either by anyone at L-36.com 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.
