David Reimer Posted July 29, 2011 Share Posted July 29, 2011 For being tropical in nature, the convection just off the Texas coast is amazingly electrical. Link to comment Share on other sites More sharing options...

Just a guess, enough dry air entrained for some evaporational cooling well below the freezing point, and updrafts and downdrafts in close enough proximity for charge separation.

eyewall Posted July 29, 2011 Share Posted July 29, 2011 The worst thing about this storm is all the beneficial rain is going to miss most of the areas that need it. Link to comment Share on other sites More sharing options...

I went the "geography w/ a concentration in tropical meteorology / climatology / vulnerability" route for my Bachelor's and Master's. Worked as an intern at the HPC a while back, but am currently working as a catastrophe risk analyst. You wouldn't happen to have a tag for that, would you?

That's somewhat common in sheared systems like this... the thunderstorms can ventilate better. What's bad for tropical systems, is good for convection.

David Reimer Posted July 29, 2011 Share Posted July 29, 2011 Well this is an interesting. The radar seems to be picking up something eerily similar to the general geography of the coastline. Since Don is a POS, does anyone care to speculate what this may be? I wouldn't think a sea breeze would be present considering the current conditions and the lack of any movement suggests this isn't an outflow boundary associated with the thunderstorms off the coast.

Wonder if this is what is showing up on radar. Link to comment Share on other sites More sharing options...
k*** Posted July 29, 2011 Share Posted July 29, 2011 The cu field throughout E TX north of the circulation center is looking increasingly agitated on SRSO visible...I think we should really start to see some filling in now. Link to comment Share on other sites More sharing options...

Ed Lizard Posted July 29, 2011 Share Posted July 29, 2011 Watch possible, but limited convection in area of mos favorable shear may preclude issuance of watch per SPC. Link to comment Share on other sites More sharing options...
wxmx Posted July 29, 2011 Share Posted July 29, 2011 Shear might be relaxing just a bit, and becoming more easterly.... there's little time left before landfall, so maybe just a bump to 50kts is possible. Link to comment Share on other sites More sharing options...

Thunderstorms in the panhandle are unrelated to Don. That's a weak surace low and trailing frontal boundary. That area of the country is beyond drought stage at this point.

I noticed that...do you think it will pull that stunt? Recon had trouble finding west winds in the last fix, and pressure was up, so the LLC was weakening, so it's possible...anything is possible with Don...that would be a bummer for Josh and Cory. BTW all the lightning activity halted very suddenly. Link to comment Share on other sites More sharing options...

No, anything out there... mesocyclone certainly won't aid the official center, if there's still one.... and it's about to landfall in probably 2 hours.
