Adding a Shure A15HP inline High Pass filter might also help a lot. Go here
for a description:

With a fairly steep 12db per octave slope shelving at 100 Hz, this is the
most affordable and useful high pass filter I've seen (although there used
to be an ElectroVoice version with an 18 db per octave slope, I believe, but
I can't find any information about it).

Such high pass filters radically reduce wind thumping of the mike and makes
it a lot easier to get by using a foam windscreen when the wind is light.
