Remnants of Ingrid

12z Euro has a bit tighter turn, hence it's a bit faster and a little to the north of Tampico... 12h difference with the GFS...day and night...literally...I wouldn't mind a consensus here.

 

North of Tampico? I only have the ECMWF out to 18 hours, but it looks like its going south to me.

12z Euro has Ingrid moving towards the NW from the start, whereas 12z GFS has slow movement towards the NNE until overnight tonight.  The next recon fix should be a pretty good clue as to which has the better handle on the track and timing.

The thing I don't understand is how the ECMWF keeps saying Manuel is the stronger system with copious precipitation. That doesn't make any sense given the satellite imagery which still shows a llc that is struggling to produce deep convection over the center.

I am noticing some of the cirrus canopy associated with Ingrid starting to get restricted. I do see the hints of an eye on visible, but the big consistent burst of convection on the E side of the dimple is a sign that westerly flow is making the inner core convection asymmetrical.

 Does seem to be moving NW already

Yes, and there are mid level elements shearing into the center from the NW already.

THE NEXT RECONNAISSANCE AIRCRAFT IS NOT EXPECTED TO BE IN THE AREA
OF INGRID UNTIL LATER THIS AFTERNOON. HOWEVER...AN EYE FEATURE HAS
BEEN PRESENT INTERMITTENTLY ON VISIBLE SATELLITE IMAGES...AND
DVORAK ESTIMATES FROM ALL AGENCIES...INCLUDING THE UNIVERSITY OF
WISCONSIN...INDICATE THAT INGRID HAS BECOME A HURRICANE WITH AN
INITIAL INTENSITY OF 65 KNOTS. INGRID IS THE SECOND HURRICANE OF

Nice temperature difference as well.

New VDM posted with some more comments, pressure was changed from drop (based on comment, guessing 981mb was just extrap)

Me too, the shear is really starting to ramp up. I think we've seen the peak for a while.

Not sure I agree. While it's easy to see on water vapor that cirrus from Manuel is restricting outflow in the southwestern quadrant, it doesn't appear to be affecting the core. Otherwise the pressure wouldn't have fallen 7 millibars since earlier.

 

In addition, winds are stronger in all quadrants that recon has sampled than earlier. Both the temperature and pressure gradient are higher as well. 

 

On a side note, upwelling shouldn't be an issue judging by the comment on the last VDM.
