Meteorologists are tracking a cluster of thunderstorms with heavy rainfall five miles east of Granbury, moving east at 10 miles an hour. The storm is said to include frequent lightning, very heavy rainfall, penny- to nickel-sized hail, and wind gusts up to 45 miles per hour.

Most of the region will also remain under a flash flood watch until 5 a.m. Tuesday. - NWS

2:48p Here is the latest overall forecast for the region from the National Weather Service: "An unseasonably strong cold front and potent upper level system will lead to a period of shower and thunderstorm activity across most of north and central Texas this afternoon into Tuesday. Although beneficial rains will fall in some areas plagued by drought, isolated severe thunderstorms and areas of excessive rain may cause problems through tonight.

Emergency Managers, public safety and elected officials, storm spotters, and event organizers should be prepared for the threat of severe thunderstorms and excessive rainfall through tonight. Precipitation chances will gradually diminish from west to east on Tuesday and Tuesday night, with much cooler weather forecast in all areas by Wednesday.

The primary threats through tonight will be excessive rainfall, large hail, and damaging winds up to 65 mph. A Flash Flood Watch has been issued for this afternoon and tonight in areas that received heavy rainfall last week and for areas that we think have the greatest potential for flash flooding. We expect rainfall amounts of 2 to 4 inches across the Flash Flood Watch area, which could cause major flooding problems especially in low lying areas and urban areas.

Scattered thunderstorms, a few strong to severe, have already developed across the area early this afternoon. The overall coverage of the thunderstorm activity will increase through the afternoon and evening hours. The time frame for the most intense thunderstorms will be from 3 p.m. to 10 p.m. today; the time frame for the heaviest rainfall will be from 4 p.m. this afternoon until 5 a.m. Tuesday morning." - NWS
