No. Weather station data will not match what is seen in Granular applications such as Field Planner. Granular applications show weather data from the TWC gridded products, not from individual weather stations.
A weather station is taking measurements at a single point on the globe and there can be a high degree of variability in physical measurements. For example we have seen instances where NOAA stations only a mile apart reported multiple-inch differences over a period of 2-3 months. This can happen with personal weather stations as well. The weather grid concept should help normalize this data across distance.
