Most of North Texas is under a severe thunderstorm watch until 11 p.m. Sunday

10:33p Oncor now says the total number of customers who have lost power has climbed to more than 36,000. - WFAA

10:21p The severe weather threat in Dallas and Tarrant counties is just about over, but if you live to the east and south the problems are just beginning. A severe thunderstorm warning is in effect for Henderson and Navarro counties until 10:45; in Ellis, Kaufman and Van Zandt counties until 10 p.m.; and in Bosque, Hill and Johnson counties until 11:15.  The primary threat continues to be very heavy rain, pea to quarter-size hail and 60-70 mph winds still possible. Power is out in parts of Waxahachie and we're starting to see heavy wind and hail pushing toward the Maypearl area. Be on alert if you are in the southern part of Ellis County.  - Meteorologist Steve McCauley

9:59p At least two cars are stuck in high water on Bannock Avenue in South Dallas. - Monika Diaz, WFAA

9:56p More than 33,000 customers are now without power, according to Oncor Electric Delivery. - WFAA

9:51p As the cold front continues moving to the southeast, we could continue to see some severe thunderstorms breaking out. We have seen a very slight weakening of this storm; it was packing winds of 60-70 mph as it passed through Dallas County. Now it's down to 50 mph in Ellis County, but if additional storms form along the leading edge of the outflow boundary, we could see a severe cell blow up in the southern part of Ellis County into northern Navarro County. The cold front is moving at about 20 mph and anyone in its patch should be on the lookout for quarter-size hail and dangerous lightning. - Meteorologist Steve McCauley

9:49p Greenville received more than an inch of rain in a one-hour period tonight. Since mid-afternoon, McKinney measured 1.3 inches of precipitation. - National Weather Service

9:43p Oncor Electric Delivery estimates that more than 27,000 customers have lost power in the current storms. - WFAA

9:38p The storm system is moving southeast, out of the Dallas-Fort Worth area. - Meteorologist Steve McCauley

9:21p Basically, anywhere a storm is forming along the cold front moving across North Texas, it rapidly becomes severe. Radar indicates the storm moving across Dallas County is dumping rainfall at a rate of up to six inches an hour. Visibility has dropped to near zero across southern Dallas County. We've also had reports of power lines and trees down with another storm in the Sulphur Springs area now moving into Van Zandt County toward Canton. The heaviest portion of the storm will be south of Dallas and Tarrant counties by 10:30 p.m. - Meteorologist Steve McCauley
