Good news: a problem affecting weather.gov and NCO has been resolved. Service should be back to normal.
Weather.gov is the public NWS website and NCO is NWS Central Operations, which runs the computing behind the forecast models.
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.
34 stations were flagged: 25 sent no usable sounding at all, 7 reported a numeric status code, 1 had a balloon burst early, 1 was 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.

| MCG 70231 | Mcgrath, AK | Ground equipment failure — the station’s tracking/receiving equipment was down, so no usable sounding was produced. | 10142 |
| 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 |
| MAF 72265 | Midland/Midland Reg. Airterm, TX | 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 |

| DTX 72632 | White Lake, MI | Ground equipment failure — the station’s tracking/receiving equipment was down, so no usable sounding was produced. | 10142 |
| MTY 76394 | Aeropuerto Intl Monterrey · Mexico | 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 |
| VHA 76743 | Villahermosa, Tab · 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 |
