Severe storms left thousands of people in north Texas without power on Sunday night as a week of dangerous downpours begins.

A cold front is likely to remain stalled over Central Texas to start the workweek, bringing a chance of thunderstorms that could be severe Monday night into Tuesday, according to the National Weather Service in Dallas/Fort Worth. Impact areas are likely to be between the Dallas-Fort Worth metroplex and Austin.

A severe thunderstorm warning has been issued for Collin, Denton, Fannin, Delta, Hopkins, Lamar and Hunt counties until 11:45 p.m. Winds of 70 mph and penny-size hail are possible. These severe thunderstorms will affect areas from Plano to Blue Ridge to Wolfe City to Paris.
