DALLAS — Although (click here) Tropical Storm Bill weakened to a tropical depression Wednesday, the weather system still packed heavy Gulf Coast rain that caused a new round of flooding from already swollen lakes and rivers in North Texas.
"Rainfall will result in significant flooding across central and eastern Texas and into southern Oklahoma through Wednesday night," AccuWeather meteorologist Chyna Glenn said.
The rain may cause life-threatening flash floods, the National Weather Service warned....
There is still flooding in some rivers. The extent of the rain now reaches north and there is flooding along the system. This is a map from NOAA. (click here) Red markers are the highest flooding.
The picture below shows the system as it traveled over San Antonio. This is from the VIP Collection of The Weather Underground. (click here)

I thought this illustrated exactly what is happening with these weather systems.
The picture below is from the same collection at The Weather Underground. This was taken at Aurora, Ohio. This clearly shows the turbulence realized when a hot weather system collides with a cold air mass. It's a shelf cloud. The character of the storm changes when there is interaction between air mass systems.

People need to take the instructions from their weather service seriously. Very seriously. We are entering a very dangerous time and there is no room for error or self-direction. Don't second guess instructions provided by weather prediction services.

There is a conduit over Louisiana and Mississippi between the two systems.
This is the prediction of precipitation for the country in the time frame of June 24 through June 28. The "key" at the bottom states "probability of below" and "probability of above." That refers to the percentage of CHANCES to precipitation. The brown color is for possibility below chance of precipitation. The green color is for possibility percentage above the chance of precipitation.This is by NOAA (click here). There are other detailed maps about future weather expectations at this website as well.
