6-hr Eta forecast vertical circulation, divergence and wind speed (shaded) valid 18 UTC August 30st.
The data on this slide clearly shows the strong upper level divergence associated with the right entrance region of the upper-level wind maximum over Canada. An area of low-level convergence beneath the upper-level divergence is associated with the low-level front. A deep area of lift is shown from the low-level front up to the upper-level right entrance region. The upward branch of the circulation shown on this slide originates along the mid-Atlantic coast, in an area of rich moisture.
