I found several threads with lists of abbreviations, but not these. So apologies for being so blatantly n00b, but could anyone provide the meaning of these abbreviations?

CINH
CWA
POPS

Also, what is the significance of convection?

CINH = convective inhibition
CWA = county warning area
POPS = probibility of precipitation

(Hope ya don't mind, Scooby, but I'm sliding this up to the weather forums so the mets can give you more. )
