.DISCUSSION...
Issued at 100 PM CDT Tue Aug 11 2026

Remnant weak vort lobe near the Brazos Valley, daytime heating,
seabreeze, and 2" PW`s are allowing for some scattered shower and
thunderstorm activity to get going this afternoon. This precip
will taper off toward early evening with the loss of heating.

Ridging, both in the lower and upper levels situated across the NE
parts of the Gulf will very slowly track and expand westward for
the remainder of the week and weekend. With building heights come
slightly warmer conditions...but just back into the "seasonably
August hot" territory. Good news is we should see some increased
wind speeds to partially mitigate those readings in the mid and
upper 90s Wed-Fri.

In terms of rain chances, slightly lower PW air is forecast to
move into the area Wednesday so we should see lower (but not nil)
shra/tstm chances and less areal coverage compared to what we saw
Monday and today. Atmosphere appears even drier Thursday. We`ll
remain within a corridor of southerly winds off the Gulf, and
minor fluctuations of moisture availability will drive any diurnally
driven seabreeze POPs into the weekend. That said, we`re still
only talking
