00Z model run on time, 7 balloon reports flagged
Model status
NWS is producing the 00Z model run on schedule. Forecast model output should reach forecasters, apps and websites at the usual times.
“00Z” is the run’s start time in UTC. NWS runs its main models four times a day — 00Z, 06Z, 12Z and 18Z — and each run begins by digesting a global snapshot of current conditions taken at that hour.
134 weather balloon launches were available to feed this run (10 in Alaska, 26 in Canada, 66 in Lower 48, 15 in Mexico, 7 in Caribbean, 10 in Pacific). “Stations available for ingest” means balloon soundings that arrived in time to be folded into the model’s starting picture of the atmosphere. Twice a day, sites across North America release balloons that measure temperature, humidity, pressure and wind all the way up. More stations reporting means a better-anchored starting point.
Balloon reports 00Z RAOB RECAP...
Twice a day, NWS and partner agencies release weather balloons that carry a radiosonde — a small instrument package that radios back temperature, humidity, pressure and wind as it climbs. Those soundings are one of the main ingredients in a forecast model’s starting conditions. This section is the roll call of stations that had a problem for the 00Z run.
7 stations were flagged: 5 reported a numeric status code, 2 had bad data removed by quality control. A handful of gaps is normal and is not by itself a sign of a forecast problem — the models are built to work with an incomplete picture.
| Station | Where | What happened | As printed |
|---|---|---|---|
| SGF 72440 | Springfield/Municipal, MO | Quality control removed part of this sounding before it reached the models: temps/moisture 872-863mb...wet bulb effect. The rest of the sounding was still used. | Purged temps/moisture 872-863mb...wet bulb effect. |
| YZT 71109 | Port Hardy A, Mexico · Canada | Quality control removed part of this sounding before it reached the models: winds 155-134mb...too slow. The rest of the sounding was still used. | Purged winds 155-134mb...too slow. |
