12Z model run on time, 33 balloon reports flagged
Model status
NWS is producing the 12Z model run on schedule. Forecast model output should reach forecasters, apps and websites at the usual times.
“12Z” 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.
106 weather balloon launches were available to feed this run (12 in Alaska, 25 in Canada, 39 in Lower 48, 13 in Mexico, 8 in Caribbean, 9 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 for the NAM.
Balloon reports 12Z NAM 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 12Z run of the NAM.
33 stations were flagged: 26 sent no usable sounding at all, 4 reported a numeric status code, 1 had a balloon burst early, 1 was missing part of the transmission, 1 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.

| GCM 78384 | Owen Roberts Airport Grand Cay · Cayman Islands | Ground equipment failure — the receiving, tracking, processing, or other ground system failed. | 10142 |
| BDA 78016 | L F Wade Intl · Bermuda | The station reported, but part of the sounding transmission was missing — specifically TTBB, the "significant levels" section that carries the extra detail between the standard pressure levels. | Missing TTBB |
| ILX 74560 | Lincoln, IL | The balloon burst early. It stopped reporting at 572 mb, so this sounding only covers the lower part of the atmosphere — forecasters and models got no data above roughly 4.6 km (15,000 ft). (572 mb ≈ 4.6 km (15,000 ft)) | Short to 572 mb |
| YPH 71907 | Inukjuak A, Que · Canada | Quality control removed part of this sounding before it reached the models: temps/moisture at 934-895 mb...wet bulb effect; 849 mb and 775 mb...super-adiabatic lapse rate. The rest of the sounding was still used. | Purged temps/moisture at 934-895 mb...wet bulb effect; 849 mb and 775 mb...super-adiabatic lapse rate |
