The 12Z Global Forecast System model is currently running as scheduled.

Balloon reports UPDATED 12Z 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.
1 station was flagged: 1 sent no usable sounding at all, 1 reported a numeric status code. 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.
| Station | Where | What happened | As printed |
|---|---|---|---|
| MAF 72265 | Midland/Midland Reg. Airterm, TX | Any reason not listed above — other or unspecified reason. “Unavailable” may appear as free text, but is not the formal definition. | No report for the NAM...10159 for the GFS |
Notices & outages ...EMWIN PDA MAINTENANCE...
This is a heads-up about planned work on EMWIN and NCO. Brief interruptions are expected during the work window rather than something having gone wrong. The notice expects an interruption of up to 10 minutes.
EMWIN is the Emergency Managers Weather Information Network, a satellite and internet feed of NWS products and NCO is NWS Central Operations, which runs the computing behind the forecast models.
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.
