.AVIATION [12Z TAF Issuance]…
Generally VFR conditions will prevail today into tonight. There
will be localized MVFR conditions this morning due to pockets of
lower BKN ceilings. These locally lower ceilings will quickly
disperse this morning. Gusty 10-15 knot winds are likely at most
.PREV DISCUSSION /Issued 353 AM CDT Wed Jul 20 2022/…
.SHORT TERM [Through Thursday Night]…
Today will be another sweltering day across southeast Texas. The
mid/upper level ridge that has been plaguing the region with intense
heat will continue to build over the CWA today. Unfortunately, this
suggests that we will add another degree or two to those afternoon
temperatures. The hottest conditions within the CWA will occur in
the Brazos Valley and our northern most counties where temperatures
of 104-106 are expected. Dew points are expected to mix down into
the 60s which will mitigate the heat index values in those counties.
However, the temperatures alone will be near Excessive Heat Warning
criteria. Therefore, an Excessive Heat Warning remains in effect in
the Brazos Valley and our northern most counties.
Farther south along the I-10 corridor and in the city of Houston,
temperatures are expected top out in the 100-102 range. Though
mixing will decrease afternoon dew points, heat index values will
still reach advisory criteria today. Don`t expect there to be much
relief at the coast where a heat advisory is also in effect. Today
will be a scorcher no matter where you are in the CWA.
Ridging remains strong on Thursday. Current blend of models used in
our grids are showing slightly lower dew points than today. Despite
lower dew points, HI values could still reach advisory criteria. For
now, we have opted to not extend heat alerts into Thursday. However,
we may decide to extend heat advisories into Thursday by later
today. Regardless of whether or not we reach advisory criteria, it
will certainly be hot enough to warrant heat safety precautions.
.LONG TERM [Friday Through Wednesday]…
Heat will continue to be the primary wx story. That said, there
looks to be a glimpse of relief the further we get into midweek.
Weakness/inverted mid-level trof should be moving westward across
the Gulf and toward the mid/lower Tx coast on Friday. Slight
chances of precip are possible locally, mainly across the
southeast 1/4 of the CWA and offshore, as this occurs. However,
the vast majority of the region should remain rain-free with
subsidence & capping still too much to overcome.
This weekend, the upper ridge will be migrating to the east across
the Southern Plains and into the Tennessee/Mississippi Valley.
Again, can`t completely rule out some isolated seabreeze activity
closer to the coast – but nothing much of significance.
Toward midweek as the ridge moves further eastward, we may see
another inverted trof make its way around the periphery of the
ridge toward the area. By then, heights and the llvl temp profile
should be a bit lower (hopefully allowing for a less hostile
environment for some iso-sct precip development). 47
Moderate onshore flow will persist today into tonight. As the
pressure gradient slightly weakens Thursday and beyond. Will keep
the caution flags flying into mid morning then let the day crew
reevaluate things. Otherwise, a fairly typical summertime wind
regime will then prevail through the period. 47
