Even with no rain the cloud cover is helping with the heat

Looks like the storms near College Station are moving southeast towards Houston.

[jasons2k]

I had nickel-sized hail when the storm peaked about 45 minutes ago, and I wasn't under the center of the core. I would not be surprised if there was larger hail in the core. Also saw winds gusting in the 50-60 mph range at Hardy Toll Road & Riley Fuzzel about an hour ago.

Rotating wall cloud reported just W of Caldwell

[Kludge]

As you would expect whent the two storm cells merged they created a lot of vertical motion and some intense rainfall. It appears the southeast-moving cell won the battle, and the overall mass will move towards Houston.

Let's hope it does, so we can get rain.
