Huge change
The weather is quite interesting right now, and it should bring fulfillment to weather enthusiasts all around our region during the next two weeks. I am expecting many chances of rain and the potential for much cooler weather to linger or get reinforced from time to time.
Since it is August we can expect this front to weaken and this could be an aid in the development of rain after the front goes by. We may have a tropical connection to the monsoon moisture in Mexico, but this is very uncertain at this time. If it becomes connected there could be flooding rainfall amounts. Below is the forecast rainfall by the 18z NAM model. This is the 1 PM run of the NAM model, the latest data and it has 2 to 3 inches of rain here by Sunday. More later on.

What is the difference between scattered thunderstorms and isolated thunderstorms?
Jean,
Isolated thunderstorms, like we had about 10 days ago, move very slowly and stay over a small area. Scattered thunderstorms, on the other hand, are more widespread. And, they move faster and can cover a much larger area. They are called scattered because they are separated by a few miles.

Dear Gary.. rain is sure nice. I was wondering. What causes a "shelf cloud" and how does it relate to a t-storm? Also, I notice that wind is usually associate with that type of cloud. Thanks for the answer.
Randy
Randy,
When rain starts falling out of a thunderstorm the air is cooled near the ground and starts spreading out ahead of the thunderstorm. This bumps into the warm moist air and a shelf cloud is often the result.
