Yes, I can.  It seems it works as soon as you put the start of the array
onto a line of its own.

$$\label{eq:fix:1} \left\{ \begin{array}{lll} \partial_t \widetilde{w} + \widetilde{v}^a\partial_a \widetilde{w} + \widetilde{w} \partial_a \widetilde{v}^a &= 0 \\ \partial_t \widetilde{v}^a + v^b\partial_b \widetilde{v}^a + \frac{\gamma-1}{2} \widetilde{w}\partial^a \widetilde{w} &= -\partial^a\phi \end{array} \right.$$
