.DISCUSSION...
Issued at 1235 PM CDT Sun Aug 3 2025

Beautiful summer day to wrap up the weekend and most of us will
see another one on Monday. The northeast winds kicked in gear for
much of last night and the result is some amazing dew points in
the upper 50s and lower 60s in the backdoor and just upper 60s and
a few lingering in the low to mid 70s on our western fringe of
Counties in E TX. The frontal boundary will begin to mix a little
more each day and as we shift back to E/SE overnight Tuesday,
expect the muggy air to resume close to where we left it last
week.

However, the extreme heat will take more ridging aloft and
drying out, with our deeper soil temps slowly edging back to
pre-rain levels of late July. However, it is not often to have
such greenery in late summer, but that may start to change in
these coming dog days of summer. However, the chance for rain is
not that far away with silent 10s in the prelims for Tyler,
Lufkin and De Queen overnight as our boundary interacts with more
NW flow convective activity over OK and N TX. This is extended
from a weak low over MO tonight and should be one and done, but
could need updates for a better push.


Some of the left over nocturnal convection may hold together into
our west for the next day before the boundary goes to the wind.
Then the sea breeze for our deep southern tier will be all we see
mid work week. Then late week as schools begin, a little farther
northward QPF signal is over much of our cwa by Friday. The next
cold front late next weekend and early next week will do even
better pooling available moisture the late day diurnal convection.
This next cool front is looking a little more shallow for the
plains and will not be like this 1030 mb air started out before
bringing us the break in the heat. This next Canadian air mass
will only be around 1020mb. So this will keep the storm track and
lower heights aloft out of our reach. We will have to wait for
better mid to late month as the continental source region builds
more surface high pressure for a longer lasting fall touch. /24/

.AVIATION...
(18Z TAFS)
Issued at 1235 PM CDT Sun Aug 3 2025

For the 03/18Z TAF update...Surface observations are still showing a
few lingering MVFR CIGs this afternoon but this should continue to
improve as we head later into the afternoon hours. I have things
returning to all VFR shortly and that will continue throughout the
remainder of this TAF period. Winds will generally be light
throughout the region throughout this TAF period. I have also
mentioned some BR for KLFK overnight, however, I am not sure that it
will impact the location below VFR limits. /33/
