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 had a balloon burst early. 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.

It stopped reporting at 749 mb, so this sounding only covers the lower part of the atmosphere — forecasters and models got no data above roughly 2.5 km (8,000 ft). The GFS run still got a usable report from this station. (749 mb ≈ 2.5 km (8,000 ft)) | Short to 749 mb for the NAM...full report in for the |
