We're starting to see the potential for a significant weather pattern change that will lend itself to the accumulation of heavy rain.
First, an upper level disturbance drifts out of the Gulf today. Then, an upper level trough sets up over southeast Texas, forcing a weak back door cool front into the region early next week.
All in all, it means the Houston-Galveston area could be in for some heavy showers in certain areas. The weather graphic indicates the bay area will see the heaviest rain by the end of the weekend. Some spotty heavier downpours will mean up to 2"-3" of rain near Galveston. The inland areas will see anywhere from .25" to .50" if you are lucky enough for a storm to park itself over your neighborhood.
The best times to dodge the rain this weekend will be early in the day, as summer heat will be a trigger as well. The best way to avoid the storms if you're spending some time outdoors, is to log in to KHOU.com and look for the radar tabs at the top of the screen.
