The humidity will stay high through the weekend as temperatures stay slightly above average for this time of year. As the ridge of high pressure aloft weakens, we will have a spot shower or t-storm chance through Saturday but most areas will stay dry. Waves of low pressure will move through south Texas Sunday through Tuesday, causing the air to be more unstable and giving us a better chance of showers and t-storms. At this time, it looks like they will be more widespread Monday, giving us our best chance of rain. Forecast models estimate that we'll see one to three inches of rain total from Sunday through next Wednesday. This could change depending on where the upper low ends up but right now, rain looks likely to start the week.
