00Z model run on time, 17 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 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 00Z run of the NAM.
17 stations were flagged: 6 sent no usable sounding at all, 9 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.
