A quick post about 92L this evening. As you can see by the 850mb vorticity map that I have included here, the system has the spin or vorticity that it needs to thrive. What’s lacking is organized deep convection wrapping around this spin. Without the convection wrapping around the center of circulation, which is clearly seen in satellite imagery, the low pressure area will remain fairly weak.
The shear values are not too strong but apparently are just strong enough to displace the main area of showers and thunderstorms off to the east and north of the center. Until and unless this shear lets up more, 92L won’t develop much despite sitting over very warm Gulf of Mexico water.
Computer guidance points towards Texas or northern Mexico but this is for the center. The worst weather, for now at least, is located well away from the center. It’s possible that Texas could see some beneficial rain from this system but how much and where is tough to say right now. The low should move steadily off to the west or west-northwest over the weekend.
We’ll see what the NHC says about this feature tonight and then see how it looks tomorrow morning. The Hurricane Hunters can get out there fairly quickly if need be should things look more interesting in the morning. For now, it’s something to watch but poses no major threat of impact over the weekend.
I’ll post more here in the morning.
