This NOAA satellite image taken Friday, July 29, 2011 at 1:45 a.m. EDT shows Tropical Storm Don continues moving through the western Gulf of Mexico, edging towards southeastern Texas. Maximum winds are at 45 mph, and intensification to Hurricane is not likely before making landfall.  In the north, a trough of low pressure moves off the Rockies and into the Plains, kicking up scattered showers and thunderstorms over the Central Plains.  A frontal boundary lingers over the Ohio River Valley, bringing scattered showers to the Northeast and Great Lakes.  High pressure over the Southeast allows for another sunny, hot, and muggy day.
