is there any difference between "next", "following" and ''subsequent'?

nothing to say - speak about weather here is the warm weather already!! we've been waiting for spring for so long... and for our happiness it has come. Everybody is sick of icy windy weather. The sun is sinking low yet but it warms and we shouldn't wear all this heavy warm clothes, burn noses with freezing winter air and sniff everytime coming into a warm place :D until next winter. They say spring has come finally - there won't be cold days any more, so we'll have warm April and May and then hot summer. here it is, correct me, please
