Aviation
12z tafs
no major aviation concerns are anticipated during this TAF period.

Southerly flow andVFR conditions will persist today. By mid late
afternoon and especially this evening, strengthening low-level
flow and residual boundary-layer mixing should yield an uptick in
wind speeds (around 15 kt sustained with a few gusts up to 20-22
kt). Occasional gustiness may continue through the overnight as
well.

As for cloud cover, MVFR CIGS should remain southeast of kact this
morning. Across the region, fair-weather cumulus are expected to
develop through the day, with bases around 070. Any regional
convection this evening should remain displaced well to the west
and north of metroplex airports. Otherwise, the only potential
concern is a re-invigoration of low-level stratus across central
texas late tonight. Strengthening flow should transport these
clouds northward towards kact, but confidence in MVFR cigs
developing before 12z Sunday is low; therefore, the TAF only
advertises sct015 through 12z. Additionally, this cloud deck may
try to approach the metroplex Sunday morning (during kdfw's
30-hour extended taf). At this time, low-level flow should keep
any MVFR CIGS southeast of the metroplex, but this will have to be
monitored closely.

through tonight
rather impressive zonal mid-level flow (at least by august
standards) is maintaining a tight low-level pressure gradient
across the southern plains currently, with recent VWP data
suggesting 925mb flow from the south around 30-35 kt. In turn,
gulf moisture continues to stream north across our area. Thus,
while afternoon mixing should be relatively deep, our low-level
moisture should be of sufficient depth to maintain surface dew
points in the 60s to lower 70s in most spots around peak heating.

With temperatures rising into the upper 90s to lower 100s, this
moisture profile should yield heat indices around 105-108 in many
locations. Therefore, have opted to issue a heat advisory for
today (as well as tomorrow -- see the long-term discussion for
more details).

Besides the heat, there's a slim chance for a shower or two across
east texas this afternoon, where the deepest moisture will
reside. However, given a lack of any clear forcing for ascent and
persistent dry air in the mid levels, refrained from introducing
any convection to the forecast at this time.

Long term issued 308 am cdt Sat aug 17 2019
Sunday through next weekend
a mid upper ridge will strengthen while expanding north into the
plains on Sunday, then remain dominant across the central part of
the CONUS through the first part of next week. Triple digit high
temperatures will be common at least through Monday. In addition,
persistent southerly winds will continue to bring gulf moisture
northward across the region, preventing any significant diurnal
drop in the dewpoint temperature. The resulting heat indices will
be widespread in the 105 to 110 range each afternoon, and barring
any unforeseen circumstances the heat advisory will likely need
to be extended into Monday at some point this weekend.

A brief opportunity for relief will occur Tuesday as a subtle
weakness develops over the southern edge of the ridge. A strong
seabreeze is progged to push inland Tuesday afternoon, and slight
chance pops have hence been added across the southeastern-most
row of counties. The rest of the region will remain hot and
rain-free, though perhaps a couple of degrees cooler than
Sunday Monday.

The latest guidance continues to indicate a break-down of the
ridging over the plains during the second half of next week as
the ridge center shifts westward into the rockies. A shortwave
embedded in the subsequent northwest flow aloft should kick off a
round of convection north of the region Wednesday afternoon.

Showers and storms will likely move southeast, some of which may
cross the red river Wednesday evening. Low-end pops have hence
been included for areas north of the i-20 corridor Wednesday
night, then to areas along and east of i-35 on Thursday as the
disturbance continues to move southeast.

A second shortwave will generate another round of showers and
storms by Friday, but at this time it looks like the disturbance
and associated convection will remain north of the region.

Near-normal temperatures and little to no rain chances will
therefore be the official forecast as we enter next weekend.

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.
