Re: ATL: Invest 91L Model Runs
Not sure how well the BAMS will do for a currently non-tropical system in the mid-latitudes. I'd take them with a grain of salt when they come out. I actually expect globals to do best of all, and once recon goes in, assuming no poof-ation, models initialized post recon tomorrow should be pretty close.
BTW, NHC recon tasking and SHIPS/BAMs model data look best when pasted inside "code" tags.

Re: ATL: Invest 91L Model Runs
SHIPS is almost certainly giving this too much of a head start, as there isn't an established surface circulation yet.
Besides above doubts about tropical models for a non tropical (at the moment) system, I also hope BAMS are wrong because they'll cheat my lawn of rain if correct.

Re: ATL: Invest 91L Model Runs
If theres any good news with this, it's that the models seem to be taking this toward a drought stricken area. We can only hope that this stays weak.

Pull up the image and look to the Lower Right hand side of the screen. They are CMC, GFS, UKMET, NOGAPS and NAM.

18Z NAM- tropical depression or weak tropical storm (had a closed isobar six hours prior to this/landfall) near Matagorda.

18Z GFS cooking now...
New 18Z GFS has almost closed a surface low by very early tomorrow morning...

Matagorda - wondering why so many others are saying SE TX, when Matagorda is the central TX coast. I'm with you, Ed - I'm thinking Corpus to Matagorda.

Re: ATL: Invest 91L Model Runs
We need some rain up here around Dallas.Right now we're under an excessive heat warning thru Monday.Temps near 108 with heat indicies above 110.If it hits near the TX?LA border some of the rain should come our way

Re: ATL: Invest 91L Model Runs
Ok this has been bothering me. Why are CLLPS and XSTR always out in left field with there forecasts. Are they more historical models?

don't know about the Clps but the XTRP is a projection line of where it would be if it continued its current motion.

CLP5 is a climatology and persistance model and XSTR = XTRP? That is just an extrapolation of the current movement.
