A potent storm system is on the way for North Texas. Sunday will start off dry with mostly cloudy skies. Scattered showers will develop by this afternoon with a few rumbles of thunder possible. The main event arrives Sunday night into Monday morning with numerous showers and thunderstorms expected. Storms could turn severe during this time. While the greatest concern will be damaging winds, storms could produce a few quick spin-up tornadoes along the leading edge of the squall line. Heavy rain will accompany these storms and could lead to some flooding issues. This activity will exit the area by midday Monday, with decreasing clouds through the afternoon. Cooler air filters into the region by midweek due to a reinforcing cold front. Expect highs into the upper-50s to low-60s. Low temperatures will fall into the 30s and 40s.
