KEY MESSAGES

- Active pattern continues with a widespread freeze likely by Sunday morning for northern half of the CWA

- Seasonable temperatures for next week with low (10-30%) chance of rain across the western half of the area

SHORT TERM

(Tonight through Sunday night) Issued at 1252 PM CST Sat Jan 10 2026

As it currently sits looking at temps we haven't warmed up all that much due in part to the strong CAA taking place as we remain in a tight pressure gradient situation. You may have noticed the northerly winds kicking up today which is also another reason why we have remained cooler. We continue to remain just below wind advisory criteria and we expect that trend to continue as the tight pressure gradient moves away from us resulting in light to mostly calm winds for tonight.

Speaking of tonight, its a tricky forecast as we could see some high to mid level clouds overspread the region helping temps to stay somewhat elevated overnight. However, if these clouds are more sparse and we see more clearing we could really see temps plummet due to excellent radiational cooling. Right now its looking more likely that Val Verde and Kinney counties will experience a freeze as they remain just to the north of the expected mid to high level cloud deck. Both of these counties have yet to experience a widespread freeze so we went ahead an issued a freeze warning that's in effect from 3AM tonight until 9AM tomorrow morning. Other areas in the Hill Country are also expected to see a widespread freeze with many areas possibly dropping into the upper 20s. However, since all of these counties have already experienced a freeze this season a freeze warning was not needed. If we get enough mid to high level clouds overnight we could see these clouds tamp down temps for Sunday as well with many areas while being seasonable, likely remaining in the upper 50s to low 60s with a continued northerly surface wind. Sunday night should not be as cold as tonight as clouds from an eventual upper level disturbance over northern mexico continue to push there way northeastward. Many areas Sunday night should remain in the 40s with a continued light northerly flow.

LONG TERM

(Monday through next Saturday) Issued at 1252 PM CST Sat Jan 10 2026

The broader synoptic pattern over the central US supports continued seasonable and cool weather through early next week. A somewhat weak upper level low moves out of northern Mexico and into South Texas by Monday that likely brings in an increase in clouds that could hold down daytime temperature. Additionally, there could also be some light precip Monday night mainly for our counties along the Rio Grande Plains and perhaps as far north as the I-10 to San Antonio to Pleasanton line though chances remain low (10-30%) Expect most of the precip from this disturbance to push out of the area by early Tuesday night as the low pushes off to the north and east. High and low temperatures should remain seasonable through this period as we continue to lack southerly low level flow as we remain in a split flow pattern with the polar jet to our north and the subtropical jet to our south. By Wednesday into Thursday the polar jet takes a dive southward creating a sharp meridional pattern aloft and remains while the subtropical jet retreats further southwards. This helps to keep the door open for the possibilities of seeing some much colder temperatures sliding southward over our area roughly a week or so away. Stay tuned for future updates.

AVIATION

(00Z TAFS) Issued at 543 PM CST Sat Jan 10 2026

VFR conditions are in store at area TAF sites through the current forecast period. Gusty north winds will ease over the next hour and remain north to northwest overnight as high clouds increase. North winds continue tomorrow, with much lower wind speeds than we observed today.
