Re: Major Hurricane DEAN: (11 PM page 245) Discussions, Analysis
Question for the experts here.
Looking at this water vapor loop http://weather.unisys.com/satellite/sat ... op-12.html there appears to be a high building over the southwestern US. looks as if it's nugding into west texas. I can see the upper low moving south of MS in the loop.
Question 1: What effect, if any, will the high have on the upper low's movement toward the west...could it cause the low to stall or get cut off?
Question 2: Is Dean's current slow climb in lat. due to it feeling the pull of the upper low? On the NHC's floater it looks like a NW jog has occured in the last couple of frames. Also looks to my untrained eyes that Dean is going to miss the next plot by the NHC. It appears he will go just to the north of Jamaca if this trend continues.
Question 3: Could that thing I'm calling a high building in west TX possibly be why some of the models were turning Dean due west, then southwest near the end of the runs?

Well its a tiny bit early to say he won't go north of Jamaica since he hasn't past the island yet. Will be interesting to see what the morning brings.
It's needs to start gaining some lat in hurry before I see that possibility. Will be fun to watch, especially for those that remember Ivan.
I agree with all of this. I do think it will be south at this point. We have some impressive wobbling that has taken place and that will continue but it seems the forecast it very good thus far. If it outright misses Jamaica to the north then maybe we can think the ridge is weaker but I tend to think it will be south it's just how far. The next question would be how much did the island disrupt the sytem if at all as it continues to the Cayman Islands.

Good info to know. I suspect there will be no change to the models though, as the atmosphere is already pretty well sampled.

Re: Hurricane DEAN: Global Models
yes, and the GFS agrees with that movement. It starts slowing it up once it is closer to the TX coast.Aquawind wrote:teal61 wrote:Upper LOw doesnt seem to move to much between 18 and 30 hours

Hmm. This is interesting. Compare the ULL between the 6z, 12z, 18z and 0z runs...
6z - http://www.nco.ncep.noaa.gov/pmb/nwprod ... 0_072l.gif
12z - http://www.nco.ncep.noaa.gov/pmb/nwprod ... 0_066l.gif
18z - http://www.nco.ncep.noaa.gov/pmb/nwprod ... 0_060l.gif
0z - http://www.nco.ncep.noaa.gov/pmb/nwprod ... 0_054l.gif
It looks a lot stronger at hour 54 on the 0z run than it did during the same time on the other three.

and good luck getting in... I lost my connection and it took me 30 minutes to get back in.
It has buffered for me a couple times but sounded great otherwise..yes I like the music too..
