.DISCUSSION...
Issued at 109 PM CST Wed Nov 4 2026

Pleasant weather conditions prevail across Southeast TX today
with temperatures mainly in the mid 70s, sunny skies, light
northerly winds and low humidity. Winds will transition to the
southeast and become variable tonight. Light winds and mostly
clear skies will result in a chilly night with lows in the mid 40s
to low 59s for our northern counties and in the 50s to low 60s
over the coastal zones.

Rain and storm chances return on Thursday as a warm front and
increasing WAA lift into our area, and a cool front moves through
later at night. Because low to mid-level moisture is limited
further inland, expect most of the activity to occur over the
coastal counties and Gulf waters. The best chances will be in the
late afternoon/evening hours, continuing through early Friday as
the front pushes well offshore.

Behind the FROPA, breezy northerly winds are expected, with the
strongest gusts along the coast and coastal waters. Ridging will
build aloft, resulting in drier conditions with highs in the 70s
and low 80s.

The pattern over the weekend differs a bit between models, but
the overall pattern brings an upper level trough over the Four
Corners, sliding into the region through early next week. While
upper forcing increases with passing vort maxes aloft and
increased PVA, moisture remains limited, mainly for areas east of
I-45. Nevertheless, expect rain and storm chances to focus mostly
on our western areas from Saturday evening through late Sunday
night. With increasing cloud cover and surface north to northeast
winds, below normal temperatures can be expected this weekend into
early next week. Expect morning temperatures in the upper 40s and
50s on Saturday and Sunday. Slightly cooler Monday morning and
Tuesday morning with lows dipping into the low 40s for portions of
the Piney Woods and Brazos Valley area. Highs will generally be
in the 60s to low 70s on Sunday and Monday.

winds. This pattern persists into the overnight hours. Light winds
settle out of the E/ESE by tomorrow mid-morning. There is a low-end
chance for patchy fog to develop across the region around
sunrise. As a result, there may be temporary VSBY reductions at
some sites. Otherwise, VFR expected through the TAF period.
