The microwave spectrum of 2-methylfuran has been measured at temperatures between 0~\circC and 50~\circC from 8.7--18.3~GHz with waveguide chirped-pulse Fourier transform microwave spectroscopy (CP-FTMW). Using the enhanced sensitivity of this technique relative to that of prior measurements from Stark-modulated instruments, we have been able to extend the assignments of the lowest energy A- and E-states from Norris and Krisher to include transitions up to J = 60 and K_\textrma = 35. We will also report on our progress towards assigning higher-lying states and compare the fit results to those from ab initio calculations.
