An operational notice from the Senior Duty Meteorologist.
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.
2 stations were flagged: 1 sent no usable sounding at all, 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.
| Station | Where | What happened | As printed |
|---|---|---|---|
| TFX 72776 | Great Falls, MT | No weather balloon data from this station reached the NAM run. The GFS run did get a report from it. | No report for the NAM...in for the GFS |
| SJU 78526 | San Juan/Intl, Puerto Rico, PR · Puerto Rico | The station reported, but part of the sounding transmission was missing — specifically TTBB, the "significant levels" section that carries the extra detail between the standard pressure levels. The GFS run still got a usable report from this station. | Missing TTBB for the NAM...full report in for the GFS |
