The 3/00Z deterministic GFS/ECMWF had come into better agreement
with the mid-level trough migration---in and around the 6/12Z time
frame. Both of these solutions have sped up the process---with the
GFS making up for its 2/00Z solution and slower progression of the
mid-level front across Hawai'i. The GFS is still a little slower
than the ECMWF. Both now---have pushed the trough through the
western half of the state---and this trough appears to be a key
component of TD Seven-C projected storm track in the day 3-4 time
frame.

The deterministic 'differences' between the 3/00Z GFS/ECMWF would
suggest using a blend of the these 2 solutions to continue
'anchoring' the mid-latitude influences and sub-synoptic scale
moisture/energy exchanges downstream between the Tropics and mid
latitudes---in the day 4-6 time frame.

Please consult the Central Pacific Hurricane Center (CPHC) for the
latest information and track forecasts concerning Tropical
Depression Seven-C.
