Well it is like anything, if you don't use it you lose it.
As said above, you need to do some with experienced folk for a bit. I do not think you have to do renewals like we do here, but maybe you should self impose a CIR renewal every year with a testing guy. Keeps you on your toes.
As for reading weather....FIX THIS>ASAP. This needs to be learned. I struggled for a while until the IR instructor I had started to break the wx up into each segment and sketched it on a rough hand drawn map. All of a sudden I knew what was applicable to me and what was not.
Last weekend I did a trip that was cloud and moderate to heavy rain, Takeoff and into the soup at 300' with a Vis of just over a mile and a quarter. Flew the RNAV approach (no LOC or ILS at most fields in Oz) and ran along at the minima to the MAP, saw the runway with seconds to spare.
Was this hard work? You betcha....but can you do it? Sure, but be current. we have pretty heavy recency requirements too, so maybe impose these on yourself for a while until you are back in the groove.
My favourite saying is .....Be a LIVE Chicken, not a DEAD Hero.
