- A weakness redeveloping over the weekend, along with deeper
  tropical like moisture and a weak surface boundary, will help to
  increase convection Saturday into next week.

.DISCUSSION...
(Today through Thursday)
Issued at 1257 AM CDT Fri Jul 10 2026

Benign conditions with air temps in the mid to upper 70s with
dewpoints only a few degrees below them. Today will be the last day
of drier conditions before a more active and wet pattern change.

Not too much change as far as current conditions and the forecast
goes: a high pressure at the surface is keeping southerly flow..
flowing into the region with weak ridging aloft. This is keeping it
plenty humid and warm, however the upper ridge will again help in
dampening convection. Moisture will pool along the Gulf Coast States
beginning over the weekend, with PWATs nearing or exceeding the 90th
percentile. The upper ridge will break down and lose its influence
over the area, allowing for a weak trough and frontal boundary to
move southward. The trough will be situated over the SE CONUS, and
we could see an upper cutoff low form from this. Those things in
conjunction with diurnal / seabreeze processes will allow for
scattered to numerous showers and storms from this weekend into
the the middle of the work week. By Tuesday into Wednesday, the
front will slow and become quasistationary over the coastline
before washing out. Aloft, the upper low is expected to move
westward over the Gulf Coast and open back up. From there into the
end of the week, chances for showers and storms will trend
downward.

Albeit warm, temperatures over the next few days will only be a few
degrees above their climatological averages. With the expected rain
and cloud cover this weekend, MaxTs will likely be kept in check.
The aforementioned boundary is a front only by name, as it will make
no noticeable difference to temps or dewpoints.

.AVIATION...
(12Z TAFS)
Issued at 611 AM CDT Fri Jul 10 2026

VFR conditions will prevail through the morning, however scattered
storms will be possible again this afternoon, mainly along the
I-10 corridor. This may produce period of lower vis and ceilings.
Convection will decrease around sunset. Winds will be light and
generally south.

&&

.MARINE...
Issued at 1257 AM CDT Fri Jul 10 2026

Surface high pressure will remain stretched from the Atlantic into
the northern Gulf through the week. This will keep a light south to
southwest flow and low seas in place. Isolated to widely scattered
shower and storms will be possible each day, with coverage
increasing a bit by the late weekend into early next week as another
weakness develops aloft.

&&

.FIRE WEATHER...
Issued at 1257 AM CDT Fri Jul 10 2026

No fire weather concerns at this time. Showers and storms will be
widely isolated at best today, with higher rain chances returning
this weekend into early mid week.
