How to read the CMA forecast on MeteoStack
On every city page, CMA is one row of the stack: each cell is one hour, coloured by rain, temperature, wind or cloud. Compare its row against the consensus line at the top. If CMA is far from the others, treat its outlier signal with caution, or as an early warning if it is a model that is strong in that situation (see above).
