Aviation
12z tafs
another quiet aviation weather day expected across north and
central texas due to the dominant ridge in place. For this
morning, a modest low level jet is once again ushering in a thin
layer of stratus, which may briefly impact kact during the next
hour or two. Otherwise,VFR and southerly surface winds will
continue at all TAF sites through Tuesday.

Short term issued 234 am cdt Mon aug 19 2019
through tonight
rather quiet, but still hot, weather remains the theme of the
short term. With mid-level ridging building northward across the
plains, more energetic westerlies will also lift farther north,
becoming even more displaced from north texas. In turn, the
surface pressure gradient and southerly low-level flow should not
be quite as strong as those of prior days. Our moisture fetch
remains respectable, though. For example, sounding climatology
shows our 00z RAOB with a mean mixing ratio above the 75th
percentile for this time of year. Similar to yesterday, this
deeper moisture will keep surface dew points from falling too
dramatically this afternoon, and many locations should once again
expect heat indices around 105-110. As such, the heat advisory
remains in effect until 7pm this evening.

Long term issued 234 am cdt Mon aug 19 2019
Tuesday through the weekend
a mid and upper level ridge will remain dominant over the southern
plains through mid week, with the primary concern being above-
normal temperatures and uncomfortably hot afternoon conditions.

That being said, veering winds on Tuesday may draw some drier air
in from the southwest, which may alleviate the conditions across
the southwest third to half of the region. It will still remain
hot, but dewpoints in the lower to mid 60s should keep apparent
temperatures below heat advisory criteria for those southwest
zones.

For the east and northeast, Tuesday heat indices may still climb
above 105, so there is a good chance that the ongoing advisory
will need to be extended for some of the forecast area. The
current plan is to hold off extending the advisory this morning,
and let the day crew make a call on if and where the 105+ heat
indices will occur.

The ridge will weaken some on Wednesday as a weak shortwave
trough rounds its northern flank. Convection associated with the
disturbance will approach the red river Wednesday night and could
affect northeastern zones by Thursday, though activity will be
weakening and only low pops have been added for areas northeast of
the dfw metroplex. The same disturbance may kick off isolated
convection Friday afternoon for areas east of i-35. The weakening
of the ridge will be minor, but enough to keep high temperatures
mainly in the mid and upper 90s for both Thursday and Friday
afternoon.

Another disturbance will drop a little farther south into texas
late Friday and Saturday, producing an even broader weakness in
the ridge this weekend. At this time, it looks like any convection
associated with this feature will remain sparse and once again
will stick with pops generally at or below 20 percent. The good
news is that temperatures will likely be much closer to normal for
this time of year as we enter the 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.
