This isn’t looking very good…Again.

The latest 12Z (8 am EDT) computer models continue to show that Ike will track northwest into the central Gulf of Mexico on Tuesday and Wednesday. However, there has been a major shift in the model tracks for Thursday and Friday. All of the models are calling for a more westward motion, bringing Ike to a landfall in Texas sometime Friday afternoon through Saturday morning. The new set of model runs is portraying stronger high pressure over the central Gulf on Wednesday and Thursday will push Ike faster than expected to the west. The trough of low pressure expected to turn Ike to the north does not arrive until Friday night, after the storm has already made landfall in Texas. The timing and strength of this trough, plus the speed with which Ike moves across the Gulf this week are still uncertain. We cannot be confident yet of a Texas landfall until we see several model runs in row that lock in on this solution. All five major models–the GFS, UKMET, GFDL, HWRF, and ECMWF–foresee a landfall between Corpus Christi and Port Arthur. The GFDL model foresees landfall as a Category 2, and the HWRF as a Category 3. Landfall could be as early as Friday afternoon, or as late as Saturday morning.
