00Z model run on time, 11 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.
Balloon reports 00Z UPDATED 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.
11 stations were flagged: 2 sent no usable sounding at all, 7 reported a numeric status code, 1 had a balloon burst early, 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.
| Station | Where | What happened | As printed |
|---|---|---|---|
| CDB 70316 | Cold Bay, AK | No weather balloon data from this station reached the model for this cycle — either no launch happened or the data did not arrive in time. | No report |
| ADQ 70350 | Kodiak, AK | No weather balloon data from this station reached the model for this cycle — either no launch happened or the data did not arrive in time. | No report |
| OTZ 70133 | Kotzebue, Ralph Wien, 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 |
| BET 70219 | Bethel/Bethel Airport, 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 |
| 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 |
| AKN 70326 | King Salmon, 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 |
| 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 |
| NKX 72293 | San Diego/Miramar, NAS, CA | Ground equipment failure — the station’s tracking/receiving equipment was down, so no usable sounding was produced. | 10142 |
| 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 |
| SYA 70414 | Shemya AFB, AK | The balloon burst early. It stopped reporting at 700 mb, so this sounding only covers the lower part of the atmosphere — forecasters and models got no data above roughly 3 km (10,000 ft). (700 mb ≈ 3 km (10,000 ft)) | Short to 700.0mb |
| FFC 72215 | Peachtree City, GA | Quality control removed part of this sounding before it reached the models: temp, moist 560 to 544 mb.. super-adiabatic lapse rate. The rest of the sounding was still used. | Purged temp, moist 560 to 544 mb.. super-adiabatic lapse rate. |
