12Z model run on time, 11 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.
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.
11 stations were flagged: 3 sent no usable sounding at all, 6 reported a numeric status code, 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 |
|---|---|---|---|
| SYA 70414 | Shemya AFB, 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 |
| FFC 72215 | Peachtree City, GA | 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 |
| FGZ 72376 | Flagstaff, AZ | 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 |
| 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 |
| KEY 72201 | Key West/Intl, FL | The station reported status code 10145. 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 10145 | 10145 |
| 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 |
| MZL 76654 | Manzanillo, Col · Mexico | Ground equipment failure — the station’s tracking/receiving equipment was down, so no usable sounding was produced. | 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 |
| PNI 91348 | Ponape/Caroline Is · Micronesia | The station reported, but part of the sounding transmission was missing — specifically TTAA, the mandatory-levels section that carries the standard pressure levels up to 100 mb. | Missing TTAA/TTBB |
