Update...
per obs, it looks like the cold front has just moved into College
Station, and on its current rate of speed, this line should be at
iah around midnight and off the coast around sunrise. In the mean-
while, the radar is really starting to fill both ahead of the pre
frontal trof and the cold front itself. Some lightning also being
detected with the activity along the front. We should continue to
see this development continue overnight and current grids seem to
have things covered. Short-range progs not really offering up too
much change from the previous runs...and will be leaving the fore-
cast as is. 41
