12Z model run on time, 32 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.
32 stations were flagged: 24 sent no usable sounding at all, 7 reported a numeric status code, 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.

Model status
A status note about the current model run.
108 weather balloon launches were available to feed this run (13 in Alaska, 26 in Canada, 39 in Lower 48, 14 in Mexico, 7 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.
