Whether to worry about the weather

Have you ever felt afraid to enjoy something?  It's been in the high 60's and 70's - great for walks and being outside - but the joy is tainted.  Here in AZ we have had a strange winter.  It started last summer - summer started late but seemed to want to make up for it by sucking up the space that should have been fall.  We had those Monsoon Haboobs you saw on the news but not much rain.  We blew from summer into winter but then after having a couple of weeks of winter cold and some rain - boom - fall shows up and hasn't gone away.  Are we going to go from fall into spring with no real winter?  Will summer show up early and ferocious?  Will we have a baked earth summer?   I guess that all there is to do is enjoy it while it is good and pray it doesn't get bad.
