Degrib: NDFD: Simple Weather 2 & 3

For convention sake, the fields of the weather string here are W=Weather type, C=Coverage type, I=Intensity, V=Visibility (not used), H=Hazard (not used). I use "C programming" convention to refer to which word. [0] refers to the 1st, [1] the 2nd, ... [4] the 5th.

To use this table, find the entry that it matches the most specifications of. In otherwords if it is W[0]=L, C[0]=SCT, use 1, but if C[0] is not in {SCT, SCHC, PATCHY, ISO, CHC}, use 9. If it matters, the precident is from left to right.

The "Simple Weather Code" is in the "Code" column.

In the following, the entries in blue were added to the Simple Weather 2 table in Feb. 2004 to create the Simple Weather 3 table.
