Divergence:
Convergence is strong in the area of developing low, but the divergence above is very weak. Also the convergence within
the decaying frontal zone is dissipating.
PVA:
The PVA area reaches to the lower troposphere where the secondary low is deepening, although there is no separate maximum
yet.
Vertical Motion (Omega):
There is ascending motion over the deepening low, but only very little in the weakening front.
