12Z model run on time, 12 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.
131 weather balloon launches were available to feed this run (11 in Alaska, 25 in Canada, 64 in Lower 48, 13 in Mexico, 9 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.
Balloon reports 12Z 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.
12 stations were flagged: 8 reported a numeric status code, 2 had a balloon burst early, 2 were missing part of the transmission. 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 |
|---|---|---|---|
| SNP 70308 | St. Paul Islands, AK | The station reported status code 10159. NWS does not publish a public legend for these codes, so we will not guess at what it means — it signals some problem with the launch or the data. unrecognised status code 10159 | 10159 |
| ANN 70398 | Annette Island, AK | Ground equipment failure — the station’s tracking/receiving equipment was down, so no usable sounding was produced. | 10142 |
| SYA 70414 | Shemya AFB, AK | The station reported status code 10158. NWS does not publish a public legend for these codes, so we will not guess at what it means — it signals some problem with the launch or the data. unrecognised status code 10158 | 10158 |
| TWC 72274 | Tucson, AZ | The station reported status code 10159. NWS does not publish a public legend for these codes, so we will not guess at what it means — it signals some problem with the launch or the data. unrecognised status code 10159 | 10159 |
| UIL 72797 | Quillayute, WA | The station reported status code 10144. NWS does not publish a public legend for these codes, so we will not guess at what it means — it signals some problem with the launch or the data. unrecognised status code 10144 | 10144 |
| GYM 76256 | Empalme, Mexico · Mexico | The station reported status code 10159. NWS does not publish a public legend for these codes, so we will not guess at what it means — it signals some problem with the launch or the data. unrecognised status code 10159 | 10159 |
| GCM 78384 | Owen Roberts Airport Grand Cay · Cayman Islands | Ground equipment failure — the station’s tracking/receiving equipment was down, so no usable sounding was produced. | 10142 |
| CUR 78988 | Not in our station table | Ground equipment failure — the station’s tracking/receiving equipment was down, so no usable sounding was produced. | 10142 |
| DRT 72261 | Del Rio/Intl, TX | The balloon burst early. It stopped reporting at 676 mb, so this sounding only covers the lower part of the atmosphere — forecasters and models got no data above roughly 3.3 km (11,000 ft). (676 mb ≈ 3.3 km (11,000 ft)) | Short to 676.0mb |
| MEX 76679 | Aeropuerto Internacional Mexico, D · Mexico | The balloon burst early. It stopped reporting at 621 mb, so this sounding only covers the lower part of the atmosphere — forecasters and models got no data above roughly 3.9 km (13,000 ft). (621 mb ≈ 3.9 km (13,000 ft)) | Short to 621.0mb |
| 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 |
| TKK 91334 | Truk/Caroline Is · Micronesia | 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 |
