Grayson County received heavy rains on Sunday night but was largely spared from the flooding and high winds that affected other areas of the state.
“It looks like there were just some thunder storms with probably a good bit of wind and some pretty impressive rainfall,” National Weather Service Meteorologist Steve Fano said of Grayson County’s overnight weather Monday morning.
The National Weather Service reports that Denison received 1.56 inches of precipitation and Sherman recorded 1.05 inches of rainfall, all as an approaching cold front whipped winds up to roughly 35 miles per hour. While Fano said the National Weather Service received no reports of damage or particularly severe weather in Grayson County, the storm system unleashed more force as it moved further south.
“The main severe weather hazards were thunderstorm winds closer to the Dallas-Fort Worth Metroplex,” Fano said. “We had some 60-65 mph winds reported out in Parker County and elsewhere closer to the Metroplex. And as the system moved further south overnight and into this morning, I know it did produce some flash flooding down in the Texas Hill Country.”
The National Weather Service initially placed Grayson County under a flash flood watch from 10:45 a.m. until 7 p.m. on Monday, but then cancelled the event before noon.
Storms are expected to remain in Grayson County’s forecast throughout the week with 20-30 percent chances through Wednesday and a 40 percent chance of thunderstorms that will carry into Thursday and Friday. Fano said Texas is usually are subjected to consecutive days of triple-digit heat and dry conditions during the month of August, but an atmospheric anomaly has destabilized the normal weather pattern and has brought with it rain and the risk for rough weather.
“Typically, we have a ridge of high pressure that sets up over the state this time of year and that ridge of high pressure has been displaced to the west,” Fano said. “Because of that, the jet stream has been able to move through the state and bring us these frequent weather systems.”
Fano said that severe weather events can develop in Texas during any month, but with a prediction for more storms already in place, he suggested that those in North Texas and Texoma keep a close eye on the week’s weather reports.
“Since there are thunderstorms in the forecast, check the forecast frequently and just stay weather aware,” Fano said.
