KEY MESSAGES

- Above average temperatures today through Saturday, then below average Easter Sunday through Tuesday.

- Medium rain chances today mainly Hill Country and I-35 Corridor.

- Widespread rain chances late Friday through the weekend.

SHORT TERM

(Today through Friday) Issued at 1250 AM CDT Thu Apr 2 2026

A mid to upper level trough is moving across NM this morning. Thunderstorms have developed along a dryline north and west of our CWA. Storms will be ongoing at the start of this period. Some CAMs show convection moving through part of our area during the morning hours today. Most of this activity will be over the Hill Country and I-35 Corridor. The low level flow across the Coastal Plains will be from the southeast and this moist flow will prevent the dryline from advancing eastward. This will limit the eastward progression of convection today. There may be enough lift in the southeasterly flow to generate isolated showers or thunderstorms this afternoon and evening. Friday another dryline will be followed by a Pacific cold front into the northwestern part of our CWA. Low chances for convection will spread into the Southern Edwards Plateau and Rio Grande Plains Friday morning and then to the Hill Country during the afternoon.

LONG TERM

(Friday night through Wednesday) Issued at 1250 AM CDT Thu Apr 2 2026

Friday night into Saturday, a stronger mid/upper level trough will move east into the Plains, sending the cold front through our CWA Saturday. This will bring widespread chances for convection spreading from the northwest Friday night across the entire area Saturday afternoon. A series of upper level impulses will move through the pattern over TX and bring chances for additional showers and thunderstorms Saturday night through early Monday. Although models are showing an extended period of convection, Saturday afternoon and evening is the time period that will most likely have activity. There is a chance for some locally heavy rain with storms Saturday with PW values forecast above 1.5". Tuesday and Wednesday will be dry as upper ridging builds over the area from the west.

Behind the front Saturday, cooler air will spread across our CWA resulting in below normal temperatures Sunday through Tuesday. Highs Sunday and Monday will be in 60s and lower 70s. Lows will be in the upper 40s and 50s. Wednesday will warm back to near normal across most of the area.

AVIATION

(06Z TAFS) Issued at 1250 AM CDT Thu Apr 2 2026

Storm chances for DRT have been removed from the latest forecast as it appears most of the activity should remain north of the terminal through the early morning hours. Farther east into the I-35 corridor, chances for convection remain, but the latest HRRR has backed off on activity being able to reach SAT and SSF. For now, will hang on to a PROB30 -SHRA for SAT and leave SSF with VCSH only. It still appears the better chance for thunder will occur at AUS during the 13-17Z time frame as a broken line of convection moves in from the west. Will continue to monitor radar trends and incoming model data and refine the timing of convection as needed. Otherwise, no significant changes were made to the overnight cigs with MVFR and IFR still expected along the I-35 corridor, with MVFR reaching DRT around sunrise.
