This table displays precipitable water** (PWAT), and the temperatures at 925mb, 850mb, 700mb, and +500mb from upper air soundings made around 00 UTC and 12UTC (6pm CST and 6am CST).  The table shows 36 stations that make these observations.  In the table above, PWAT is in inches and all temperatures are in degrees Celsius. **Precipitable Water measure of the depth of liquid water at the surface that would result after precipitating all of the water vapor in a vertical column over a given location, usually extending from the surface to 300 mb.

(About the SPC Analyses Used here at times: The 00z maps are produced at 01z using the available upper air data with a first guess from the 18z NAM 6-hour forecast for the objective analysis. The 12z maps are produced at 13z using the 06z NAM 6-hour forecast as a first guess for the objective analysis. If the 18z or 06z NAM runs are unavailable, a first guess from the 12-hour forecast of the 00z or 12z NAM is used. Errors may result if NAM model data is not available, or if sounding data is late or erroneous. )

Note: In both sets of graphics (US & vicinity and Europe, etc.), the lower right date/time stamp is occasionally WRONG! The upper left date/time stamp is always correct.

MANDATORY LEVELS: By international convention, these specific pressure levels must be reported in the RAOB message: the surface, 1000, 925, 850, 700, 500, 400, 300, 250, 200, 150, 100, 70, 50, and 10 mb.. The information for some of these levels is plotted routinely on constant pressure charts to show the spatial variability of these levels and it is used as input in the numerical weather prediction models.
