I thought I'd forward this forecast of a toned down storm from Al
Pietrycha, which came through the ENCWW listserv last night:

>I agree that this will be a strong storm but I disagree that it will
equal

dirty
>synopsis.
>
>Today's system that moved through the Gulf region has removed much of
>the tropical moisture. Thus, the amount of available latent heat will
be
>limited. This was not the case in '93 which aided in the explosive
deepening
>of that system
>
>The 500mb support is a little too far west initially. This will become
better
>coupled with the sfc Low but not until the system is further up the
coast-
>say NCish. The '93 storm was well stacked as it started up the ERN
Seaboard.
>This will happen but too late to be a major factor for the SE.
>
>The main sfc Low is not progged to rapidly deepen as far west. This
looks
>to really start to take shape north of FL instead of south of BHM.
This ties
>in nicely with the reasons mentioned above. Also the sfc temp gradient
is
>not as strong as in '93. This too will influence the sfc Low's
deepening.
>
>Yes it will be a SN maker for parts of the deep south but it will not
be
>the storm of the century.

>Thoughts anyone?
