DISCUSSION

Issued at 1233 AM CST Sun Nov 8 2026

Upper trof/low situated across ncntl Mexico. The first ejecting shortwave (one of many) is producing a large area of precipitation between Dallas and San Antonio. Some of this precip will probably clip some of our northern zones in the next several hours. Additional precipitation will probably develop further south across south Texas closer to a surface trof today...some of which may track into parts of the area later in the day. This too, will mainly be light...and overall accumulations will be negligible the further east (I-45ish) one goes. With abundant cloud cover, readings won't have much of an opportunity to warm...so we're probably looking at highs mostly in the 60s to low 70s depending on location.

Same general setup is in play again on Monday, with highest rain chances across our southwest CWA. By Tuesday we'll see the upper low slowly lift ene across the state. Cloudiness will linger as will lowish rain chances.

Heading into mid-late week, amplified ridging across the western CONUS and deepening trof across the eastern CONUS will bring an an drier northwesterly flow aloft. Looking for a cold frontal passage Wednesday night followed by dry, cool weather for the remainder of the week. 47

AVIATION

(12Z TAF Issuance) Issued at 511 AM CST Sun Nov 8 2026

Light scattered showers are currently pushing across the Brazos Valley this morning. Additional showers are expected approach from the west later today. Rainfall chances and coverage are still broadly greater west of I-45, thus have opted to maintain PROB30s at most TAF sites for this afternoon. Rain chances lull tonight. Isolated patchy fog/CIGS could develop overnight into early Monday with KCLL most at risk for MVFR/lower FLs. Another round of showers will be possible on Monday, with coverage and chances greatest W/SW of the Houston Metro area.
