Satellite loops show an inner core developing and deepening continues at the rate of about 1 mb an hour. Gradual strengthening is forecast over the next few days. Matthew could become a major hurricane in the Central Caribbean. We will be examining the latest weather models and will post about them once the European model cycle is done.
GFS MODEL & EUROPEAN MODEL ANALYSIS
The video from this morning illustrated how the GFS model last night changed its view of how the trough in the west was going to behave. The more progressive look on that particular run was another model flip into a different direction. As expected, models have now gone back to the idea of a deep trough coming into the Plains and Middle Mississippi Valley. Both the GFS model and the European model show this.
