Isolated shower produces heavy rain

Here's why we put a 20% chance of rain in the forecast.

Sure, chances are you'll stay dry. But there's enough moisture in the atmosphere that if a shower does show up on Live MegaDoppler13, the rain could be heavy.

That happened on Tuesday. An isolated thundershower developed in northern Harris County and just sat there for over an hour. Winds in the mid-levels of the atmosphere were weak so the storm didn't move much. The image to the left shows the radar rainfall estimate. The dark green shading represents more than 3 1/2" of rain!

The chance of rain will be going up this weekend. A stronger storm will be pushing across the state on Saturday and Sunday. Again, some of the rainfall will be heavy. I'm also concerned some of the storms could produce isolated wind damage.

My wife and I closed the sale on our home in the Height's the day before Alisa came in. She was 7 months pregnant with our first daughter, and our power was off for 16 days; it was pure misery. My brother and I watched either a tornado or a down burst twist the entire top of one of my 100 feet tall oaks trees and drop it on my next door neighbor's garage apartment.
