Tropical Depression Bill moved northward across north Texas on Wednesday and brought heavy rain to parts of Texas and Oklahoma. At 11:00 p.m. EDT on Wednesday the center of Tropical Depression Bill was located at latitude 33.7°N and longitude 97.3°W which put it about 65 miles (105 km) north-northwest of Dallas, Texas. Bill was moving toward the north at 10 m.p.h. (16 km/h). The maximum sustained wind speed was 30 m.p.h. (50 km/h). There were wind gusts to 50 m.p.h. (80 km/h) in some thunderstorms. The minimum surface pressure was 999 mb.
Bill still has a well organized circulation at the surface and throughout the troposphere. There is still a warm core in the middle troposphere and divergence in the upper levels. The upper level divergence pumped out the same amount of mass as converged in the lower levels and the surface pressure remained constant on Wednesday. Some drier air is wrapping around the southern part of the circulation and most of the rain is falling north and east of the center. The slow movement of Bill has generated significant amounts of rain and flooding is occurring in some parts of Texas and Oklahoma. A few thunderstorms have also produced damaging wind gusts.
Bill is expected to turn toward the northeast as is moves around the western end of a high pressure system centered off the southeast coast of the U.S. It will move slowly across Oklahoma on Thursday and across Arkansas on Friday before moving up the Ohio River Valley during the weekend.
