The map ended up plotting as expected, but still returned the Value Error, so I ignored the error with try and except and continued. 
Is there really not a fix for any of this yet?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,258735262

It was fixed by setting extend='both' in the contourf function, and I got rid of the triangles in my colorbar by setting extendfrac=0 in the colorbar function.

The funny thing is, the code worked just fine yesterday, but when I ran it again today, I encountered this problem. 

Non-working code:
`pcp = ax.contourf(x, y, data, cmap=cmap, levels=bounds, transform=proj, norm=norm)`
`cb = plt.colorbar(pcp, cmap=cmap, pad=0.01, shrink=1, norm=norm, ticks=labels, orientation='horizontal')`

Working code:
`pcp = ax.contourf(x, y, data, cmap=cmap, levels=bounds, transform=proj, norm=norm, extend='both')`
`cb = plt.colorbar(pcp, cmap=cmap, pad=0.01, shrink=1, norm=norm, ticks=labels, orientation='horizontal', extendfrac=0)`

I'm pulling data from the NCEP NOMADS server, not sure if that matters, but I've found the data download to be slow and pretty questionable at times. ","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,258735262
