It's all just a matter of steering currents. The TUTT low to the southwest of it for the last few days has dissipated. If you notice on water vapor imagery, the westerlies/trough just to the NW of it has nothing separating it from Emily. The TUTT is gone. So now, upper-level steering currents are shifting form southeast to northeast, in response to the upper ridge building in from the SE United States. Meanwhile, the low-level easterlies still haven't budged. They've been persistent the whole time. So it's all just a matter of balancing a chaotic fluid. Right now, Emily is simply in a weak steering flow...waiting for the surge of upper-level NE flow to commence. Or (god forbid), the trough diving in unexpectedly and shoving this thing more NNW. However, it should still go into Mexico WNW or W at its current rate. The westerlies/trough to its NW shouldn't be changing too much to cause any heart attacks for those who are forecasting this thing to NOT go into Texas.
