Notices & outages SPOT FAILOVER...

This is a heads-up about planned maintenance. Brief interruptions are expected during the work window rather than something having gone wrong.

For most people this is invisible — forecasts keep coming. It matters most to anyone pulling NWS data directly, and to forecasters who lean on the affected feed.

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-East is pointing mesoscale sector 2 at a point about 70 mi WNW of North Platte, NE — to support severe thunderstorm and tornado forecasting. 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.

Balloon reports 12Z GFS 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 GFS.

31 stations were flagged: 25 sent no usable sounding at all, 5 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.
