Time Height Charts – temperature advection and temperature
The data on these charts compares the patterns of model forecast temperature advection at BGM on October 25th, to the patterns of model forecast temperature advection at ELM on January 2-3. Temperatures above 0 degrees C are shaded red, and temperatures between 0 and 2 degrees C are shaded yellow. In both cases, the RUC model was forecasting weak temperature advection patterns around the time when rain changed to snow at both stations. Weak low-level cold advection was indicated at BGM just prior to the change from rain to snow on the 25th, while weak low-level warm advection was indicated at ELM.
