Following the European model the system looks to make landfall near the TX-LA border as a strong tropical storm or category 1 hurricane sometime Saturday afternoon/evening. But it usually still has an influence, as it changes the position of the entering jet stream from the west. The model is run twice a day at 0z and 12z. Lower pressures are indicated in dark blue. There are different pathways that it can take. Europe is again neutral, with hints of higher precipitation over Scandinavia, due to the higher frequency of storms moving over this area.

The ECWMF model runs both in a "deterministic forecast" mode and as an ensemble. It has a lower resolution, and it typically doesn't perform quite as well (proposed NOAA budget cuts will make matters worse, too). The precipitation forecast also nicely shows the “dipole” pattern over the United States, with drier in the south and wetter in the northern parts and with a higher chance of more snowfall, under the jet stream. The European Centre for Medium-Range Weather Forecasts (ECMWF, the Centre) is an intergovernmental organization supported by 34 countries and based near London.
