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.
3 stations were flagged: 2 sent no usable sounding at all, 1 reported a numeric status code, 1 had bad data removed by quality control. 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 |
|---|---|---|---|
| FFC 72215 | Peachtree City, GA | 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 |
| UIL 72797 | Quillayute, WA | No weather balloon data from this station reached the model for this cycle — either no launch happened or the data did not arrive in time. unrecognised status code 10159 | No report for the NAM...10159 for the GFS |
| YVQ 71043 | Norman Wells A, Nwt · Canada | Quality control removed part of this sounding before it reached the models: temps/moisture at 496 mb, 360 mb, 298 mb and 249 mb...non-meteorological and super-adiabatic lapse rate. The rest of the sounding was still used. | Purged temps/moisture at 496 mb, 360 mb, 298 mb and 249 mb...non-meteorological and super-adiabatic lapse rate |
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 1 at a point about 40 mi W of Rock Springs, WY — to support flash flood and heavy rainfall 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.
