12Z model run on time, 37 balloon reports flagged, satellite sector moved
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 UPDATED 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.
37 stations were flagged: 29 sent no usable sounding at all, 7 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.

Satellite moves MDS STATUS...
Each GOES weather satellite has two “mesoscale sectors” — small, movable windows that the satellite photographs roughly every 60 seconds, far more often than its routine full-disk and continental scans. Forecasters aim them at whatever is most important that day. This section announces where they are being pointed and for how long.
GOES-West is pointing mesoscale sector 2 at a point about 120 mi WNW of Elko, NV. That means this patch of sky gets a fresh satellite image about once a minute instead of every 5 to 10 minutes, so forecasters can watch storms develop almost in real time.
