We may need to monitor the WSW progression of a meso low/vortex currently over Mississippi and the mid/upper low/trough in the Gulf heading generally W. Although we have dried out a bit, daytime heating and some destabilization is possible later this evening as that system moves across Southern Louisiana and enters SE Texas. We will see.

Being on the west side of the meso low/vortex is why we are dry right now. The dry air has to go somewhere. It is like the west of a hurricane, dry, while east side is wet.srainhoutx wrote:We may need to monitor the WSW progression of a meso low/vortex currently over Mississippi and the mid/upper low/trough in the Gulf heading generally W.

Anyone else watching the big blob on radar coming in from the east?

Betting we'll see more storm coverage tomorrow and over the weekend as the leftover boundaries and moisture increase overnight. Need all the rain we can get before next week's heat returns in earnest. Storms right now to our east are weakening and doubt they will make it much farther tonight.

^^ look at the PW map a and radar loops this morning that wedge of dry air has moved west of us and the deeper moisture is headed right towards us.
Ok yall, I am no expert.. far from it. Is it me or do I see a tiny little circulation with that "blob" in the GOM?

Hey kayci. There is a trough axis from just SW of Panama City, FL to Tampico, MX across the Gulf. Most of the circulation is at the mid/upper levels. Surface Pressures across the Eastern half of the Gulf is rather high, but PW's or precipitable water values are running in the 2+ inch range meaning a tropical air mass is lurking. The SPC (Storm Prediction Center) has our part of the world in a 'text' area as the disturbance moves generally W. The main concern will be some heavy tropical rains with any storms that develop later today.

Thanx! More rain is good for me just no flooding please
Nice, so it goes something like 'Complex of storms, imbedded in a pocket of very moist air, headed towards Houston during peak heating, should mean watch out for flooding. Instead it defies all logic and weakens anyway.'
It looks like some cells are trying to develop ahead of the complex. We probably do have a decent shot of rain, maybe just not how we thought.
NHC has a 10% chance of developement on our "blob" in the Gulf:

Skies are clouding up here in Stafford, getting quite breezy too. I have heard some thunder,but it's been in the distance. Keeping my fingers crossed that my lawn gets some water. Interesting to see clouds on one side of the house and semi clear skies on the other.

Nice heavy rainstorm on the lawn after a day break!:)
Different day, same story up here. Everthing falls apart just as it gets close to me. The forcefield wins again.

Just a few drops here in Stafford thus far, lirerally a few drops. I am still hoping. Sigh....
Not a drop at my house since this all began over a week ago. Still just as dry a it was the first week of July. At least many are seeing some rain.

Right on cue, the morning clouds are giving way to developing TC field and showers are forming as we reach convective temps of the mid 80's.
