| Triggering potential:
(0) weak to (3) strong
(0) No triggering mechanism: cap is too strong, no
boundaries such as dry-line,
no fronts, ...
(1) Weak triggering: Sufficient convective heating;
weak boundaries, anticipated
triggering over high terrain to wesst, weak large scale forcing
(2) Moderate triggering: Sufficient convective heating;
weak-moderate dry line, front,
or other boundary; moderate large scale forcing, model
forecast of precipitation.
(3) Strong triggering: Sufficient convective heating;
well-formed dry line, front,
or other boundary; strong large scale forcing, deep moisture,
model forecast of significant precipitation.
