Re: slip sliding west

Earlier during the last Vis. loop, it looked like the LLC was heading just north of due west towards FL, and it still may be. But on the WV loop, you see there was a bit of a dry slot near a mid to upper level low, which seems to be filling in a little and even a hint of convection building near it. If you look at this part of the system, it is not moving much - maybe a little NW, but if you look at the Dvorak loop, it looks like the main part is moving due west towards Cape Canaveral. Of course this is typical of weak systems where it is not vertically stacked at the low and mid-upper levels. We really won't know until the next Vis. images are available in the morning.

Also of interest, check out the latest latest GFDL run on 99L, look east of the islands at the end of the loop...it is the wave off of Africa. Nearly all of the models are now developing the wave. The high in the middle of the atlantic should allow for the system to move close to the US.
