The model now indicates that the eddy will form directly over the state Thursday. This change has significant implications for the sensible weather expect. Gusty, shifting winds will mark the closing of the system Thursday, before it pulls to the northeast by the weekend. Many inches of rainfall would soak the state during the next five days--some areas receiving over a foot of rain if the ECMWF is correct. Cisco
