Why are VIX futures inverted (April at 16.41, May at 14.94) when the April futures are not at a very high absolute level? And when the front month VIX future (UX1) is higher than the second month (UX2), usually spot VIX is even higher than UX1, but now it is lower, at 16.01.
Some events that could be affecting the VIX term structure are the Good Friday holiday (after which VIX should rise, other things being equal) and the upcoming French elections.
