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.

14 stations were flagged: 4 sent no usable sounding at all, 9 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.

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 270 mi SW of Hilo, HI — to keep a close eye on a tropical system. 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.
