SIGNIFICANT WEATHER PROGNOSTIC CHARTS
11-1 SIGNIFICANT WEATHER PROGNOSTIC CHARTSS ignificant WEATHER PROGNOSTIC CHARTS (progs) (Figure 11-1) portray forecasts of selected weatherconditions at specified valid times. Each valid time is the time at which the forecast conditions areexpected to occur. Forecasts are made from a comprehensive set of observed WEATHER conditions. Theobserved conditions are extended forward in time and become forecasts by considering atmospheric andenvironmental processes. Forecasts are made for various periods of time. A 12-hour prog is a forecast ofconditions which has a valid time 12 hours after the observed data base time, thus a 12-hour forecast.
11-6 Surface Pressure Systems Surface pressure systems are depicted by pressure centers, troughs, and isobars. Formats used for each feature are the same as used for the surface prog panels of the U.S. low-level significant weather prog
