CSI and heavy snow
Numerous researchers have noted heavy snow associated with CSI
- have noted bands of heavy snow with CSI
- unfortunately, there is no good way to predict exactly where the bands will set up.
McCann (1996) studied 14 cases of 10 inches or more of snow east of the Rocky Mountains.
- He noted that the tighter the horizontal temperature gradient the better the chances for slantwise convection.
- CSI may be common in cases with a strong horizontal temperature gradient and CSI.
REMEMBER WHEN 1e DECREASES WITH HEIGHT, THE AIRMASS IS CONDITIONALLY UNSTABLE AND WILL PRODUCE UPRIGHT CONVECTION IF THE AIRMASS IS SATURATED AND THE PARCEL IS LIFTED
