Yep models are developing a surface low that moves slowly north through the area with some very heavy rain associated with it.Some models even show a feeder band like setup once the surface low is north of us mid week.

Yeah that will be intriguing to watch, the CMC even has a secondary surface low forming which explains its really high rain fall totals, lots to watch

Could end up being more of a south and central Texas event but still too far out to determine that.

Cpv17 its looking better for our neck of the woods, everyone should get at least 1-3 inches over the next 7-10 days, I do agree with you though where that heavy feeder band will set up is anyones guess right now, but potential is their for some hefty totals across the area

Me too. It’s been amazing all day except when the power went out for an hour or so during a windy storm around 11 this morning. Luckily it was only 73 outside so it wasn’t a big deal. I’ll take this all summer long

A lot of that is in the 8-14 day range. We'll see.

NWS is in general agreement that it will be wetter than normal, but not striking. I like to cool part. More clouds! 8-)

The 6-10 day outlooks also call for cooler than normal as well, more rainy, especially in South Texas. With a surface low, it depends on the setup. Watch for streaming Gulf moisture and rain bands on the east side.

Clouds - gotta love 'em. If only the entire summer were like this with our grass and foliage actually green going into football season!
