southeast Texas is currently under partly cloudy skies with
temperatures around 90 degrees. The mesoscale convective system currently near ih-35
appears to be stalling out. Another mesoscale convective system further south near Corpus
Christi appears that it might make it into Jackson County. This
will depend upon how much coverage out in front of the system
there is as multiple cold pool interactions could stall out the
mesoscale convective system.
The upper level weakness out in West Texas will continue to push
eastwards tomorrow and will provide a slight chance of rain
through the weekend. Forecast soundings are not impressive
Saturday and Sunday as cape and precipitable water values are limited.
Monday and Tuesday of next week appears to be mostly dry with
near normal temperatures as soundings dry out. On Wednesday an
upper level trough will begin to approach the area from the west.
The GFS is more progressive with the feature than the European model (ecmwf). The
GFS also pulls the system farther north and keeps precipitation chances
limited across southeast Texas. The European model (ecmwf) on the other hand has
the system stalling out in the Midwest and brings more positive vorticity advection through
our area. The European model (ecmwf) also had a TUTT low moving into the eastern
Gulf on Thursday. The Canadian tends to lean towards the GFS. Will
wait for model consistency on this before making any significant
changes. 23

broad surface high pressure across the southeastern United States
and eastern Gulf of Mexico will keep winds onshore through the
upcoming week. Pressure gradient looks to strengthen early next week
which may lead to caution statements for the offshore waters. 38
