00Z model run on time, 10 balloon reports flagged, satellite sector moved
Model status
NWS is producing the 00Z model run on schedule. Forecast model output should reach forecasters, apps and websites at the usual times.
“00Z” is the run’s start time in UTC. NWS runs its main models four times a day — 00Z, 06Z, 12Z and 18Z — and each run begins by digesting a global snapshot of current conditions taken at that hour.
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.
10 stations were flagged: 2 sent no usable sounding at all, 7 reported a numeric status code, 1 had a balloon burst early, 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 |
|---|---|---|---|
| JAX 72206 | Jacksonville/Intl, FL | 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. | No report |
| OTX 72786 | Spokane, 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. | No report |
| OTZ 70133 | Kotzebue, Ralph Wien, AK | Ground equipment failure — the station’s tracking/receiving equipment was down, so no usable sounding was produced. | 10142 |
| BET 70219 | Bethel/Bethel Airport, AK | The station reported status code 10159. NWS does not publish a public legend for these codes, so we will not guess at what it means — it signals some problem with the launch or the data. unrecognised status code 10159 | 10159 |
| SNP 70308 | St. Paul Islands, AK | The station reported status code 10159. NWS does not publish a public legend for these codes, so we will not guess at what it means — it signals some problem with the launch or the data. unrecognised status code 10159 | 10159 |
| AKN 70326 | King Salmon, AK | The station reported status code 10159. NWS does not publish a public legend for these codes, so we will not guess at what it means — it signals some problem with the launch or the data. unrecognised status code 10159 | 10159 |
| TWC 72274 | Tucson, AZ | The station reported status code 10159. NWS does not publish a public legend for these codes, so we will not guess at what it means — it signals some problem with the launch or the data. unrecognised status code 10159 | 10159 |
| GCM 78384 | Owen Roberts Airport Grand Cay · Cayman Islands | Ground equipment failure — the station’s tracking/receiving equipment was down, so no usable sounding was produced. | 10142 |
| ANN 70398 | Annette Island, AK | The balloon burst early. It stopped reporting at 400 mb, so this sounding only covers the lower part of the atmosphere — forecasters and models got no data above roughly 7.2 km (23,500 ft). (400 mb ≈ 7.2 km (23,500 ft)) unrecognised status code 10141 | Short to 400mb..10141 |
| KWA 91366 | Kwajalein/Bucholz Aaf, Marshal · Marshall Islands | The station reported, but part of the sounding transmission was missing — specifically TTAA, the mandatory-levels section that carries the standard pressure levels up to 100 mb. | Missing TTAA/TTBB |
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 65 mi NE of Fresno, CA — to support fire weather operations. 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.
