Corpus Christi, TX weather balloon

Launch of 2026-10-28 00Z (evening launch, US time) · ground level 43 ft above sea level, 81°F at launch

What it means

Freezing level about 14,700 ft up

Rain stays rain at the ground. Hail has a long way to fall through warm air and often melts smaller.

Wind at crane height: 14 mph from the ESE

At about 260 ft the wind was 14 mph, against 15 mph at the ground. Wind at height is often much stronger than at the ground, especially at night and in the morning. Many outdoor aerial lifts are rated for winds up to 28 mph; crane limits depend on the crane and the load, so check its manual.

Moderate storm fuel (1,018 J/kg CAPE)

If something lifts the air (heating, a front, hills), storms could grow strong. The wind doesn't change much with height, so storms that form would tend to be short-lived. Whether storms form at all depends on other things too.

1.60 inches of water in the air

Moist air. Showers and storms could bring heavy rain for a short time.

About soundings

Balloons go up at about 6 a.m. and 6 p.m. Central time (12Z and 00Z) and take about 2 hours to climb. The numbers show what the air was doing at launch, so they are a snapshot, not a forecast. Conditions change through the day, especially in the afternoon and when a front passes.

Wind at crane height is the measured wind about 260 ft (80 m) up. Storm fuel (CAPE) is how strongly a rising bubble of air would keep rising. Wind change with height (shear) helps storms last and turn severe. Water in the air (precipitable water) is how much rain the whole column would make if it all fell. Notes like these are a planning aid, not an official forecast or warning. For warnings, follow the National Weather Service.

Want this for a job? AtmosDays Plus and Pro show the HRRR model's hour-by-hour wind at crane height for each jobsite, for the next 2 days. See how it works.

Data: NOAA National Weather Service upper-air sounding, via Iowa State University's Iowa Environmental Mesonet. Explanations by AtmosDays; storm fuel is for the most unstable air in the lowest 10,000 ft or so.
