00Z model run on time, 6 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.
129 weather balloon launches were available to feed this run (10 in Alaska, 26 in Canada, 62 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 for the GFS.
Balloon reports UPDATED 00Z 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.
6 stations were flagged: 3 sent no usable sounding at all, 1 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.

| KWA 91366 | Kwajalein/Bucholz Aaf, Marshal · Marshall Islands | 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 | Unknown for NAM..10159 for GFS |
| NKX 72293 | San Diego/Miramar, NAS, CA | 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. The GFS run still got a usable report from this station. | Missing TTAA for NAM..full report in for GFS |
| SLE 72694 | Salem/Mcnary, OR | 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. The GFS run still got a usable report from this station. | Missing TTAA for NAM..full report in for GFS |
