There’s a good chance for scattered rain and storms in our area through the morning and into the early afternoon. The rain chances continue, but decrease, later this evening and going into Thursday and Friday.

This weekend we’ll still have a slight chance for scattered showers as the dust moves in. Temps will start to rise as more sunshine comes out, in the low-90s this weekend.

Since Friday of last week, we have had an influx of tropical moisture into the area, and it doesn’t take much to squeeze it out of the atmosphere in the form of showers. Think of a sponge that is soaked. One little squeeze, and water comes out. 

The chance for scattered storms and downpours continues the entire workweek ahead of Saharan dust.  The storm potential will diminish as we head into the end of the work week, and into the weekend, when the dust should be entering the Houston area. 

The good news with the dust, which is over the Atlantic Ocean and moving into the Caribbean Sea soon, has helped keep the tropics calm, so no hurricanes and tropical storms anywhere in sight, likely for the rest of this month. Tropical Storm Dolly, is the exception, since it formed in the Northern Atlantic Ocean but will pose no threat to land.
