KEY MESSAGES

Updated at 552 AM CDT Sun Oct 18 2026

- Cooler air remains through Monday morning with temperatures on a slow warming trend back into the 80s and 90s later in the week.

- No rain is expected through the extended forecast period.

SHORT TERM

(Today through Monday) Issued at 125 AM CDT Sun Oct 18 2026

Another crisp and cool fall morning can be expected to start the day today. We could see lows dip as low as the low 40s in the Hill Country and Southern Edwards Plateau regions. Areas along and south of the I-35 Corridor should see a bit warmer lows with upper 40s to near 50 degrees expected. We warm up nicely during the day with highs a few degrees warmer then yesterday with 70s area wide (warmest along and south of the I-35 Corridor). Unlike the past few days winds should be very light to almost calm through the day under plentiful sunny skies. Tonight expect lows to be much warmer as return flow at the lower levels and increasing clouds overnight sets up shop over our area. Thus we should see lows closer to average in the low to mid 50s for this time of year. By Monday we should see even warmer highs as we begin to warm back up with highs in the upper 70s to low 80s as ridging continues to remain over the central and southern U.S.

LONG TERM

(Monday night through Saturday) Issued at 125 AM CDT Sun Oct 18 2026

Monday night we continue our warming trend as broad ridging over South Central Texas becomes more amplified heading into the late week period. Each day we will continue to warm until we eventually jump back above normal for highs beginning Tuesday and especially Wednesday and into the weekend. This means we should see highs in the low 80s before highs ramp up into the upper 80s to low 90 by the end of the week. Additionally we will see the return of more humid conditions then what we currently have this weekend with dewpoints back into the 50s and 60s compared to the very dry 30s and 40s currently. Eventually, a trough is progged to move over the western U.S late in the period but the elongated upper ridge may limit impacts for our area associated with this feature. At the moment the forecast looks to remain dry and continues to be that way throughout the entire extended portion of the forecast.

AVIATION

(12Z TAFS) Issued at 552 AM CDT Sun Oct 18 2026
