The center of Tropical Depression Hermine is located west-southwest of Dallas, TX and will continue moving northward through the southern Plains during the day. A threat of excessive precipitation is forecast from central and northern TX through central and eastern OK into southeastern KS, far southwestern MO and far northwestern AR. Widespread total precipitation amounts of 3-5 inches are possible with the potential for isolated maximum amounts of 8-12 inches. In addition to heavy rainfall, a few brief tornadoes may be possible across central OK and north-central TX during the afternoon and early evening. 

Severe Weather

There is a slight risk of severe thunderstorm from central OK into north-central TX due to the possibility of tornado formation within Hermine. Isolated thunderstorms are anticipated to develop from far northeastern WY eastward into western SD, western NE, and northeastern CO during the late afternoon and early evening. A few stronger storms may be capable of producing small hail and gusty winds. Additional isolated thunderstorms are expected across ME this afternoon and evening with the possibility of some hail and/or locally damaging wind gusts.

A low pressure system located just south of the southernmost Cape Verde Islands has a high (70%) chance of becoming a tropical cyclone during the next 48 hours.
