More rainfall expected throughout the week
Denton residents woke up to rain and thunderstorms Monday morning, part of a squall line that moved quickly enough to avoid flash flooding but slowly enough to mitigate any severe weather risk, too.
The line developed in the Panhandle overnight Sunday, according to Joe Harris, a meteorologist with the National Weather Service in Fort Worth.
The system continued to form storms as it moved through North Texas, but by afternoon the clouds yielded to blue and sunny skies.
A total of 1.05 inches of rain was recorded at Denton Enterprise Airport overnight Sunday into Monday.
More rain is expected through the week, Harris said, including a 40 percent chance of rain today.
The unstable weather pattern is possible because of a weakness aloft in the atmosphere, Harris said. North Texas is sandwiched between two high-pressure systems and two low-pressure systems, which allow daytime heating to create thunderstorms.
It is unlikely that any systems will get organized enough to dump the kind of rain that fell on Granbury on Sunday, Harris said. More than 7 inches of rain fell there, causing flooding in low-lying areas and raising levels at Granbury Lake about 5 feet in a day.
A high-pressure ridge is building over North Texas and that will begin to lessen the chances of rain each day this week, so that by Friday and Saturday meteorologists expect only a small chance of rain in the afternoon.
Until then, residents can expect between 1/4 inch to 1/2 inch of rain with each storm. The pattern will affect temperatures, too, which are expected to reach only the upper 80s through Friday.
It all adds up to a little bit of drought relief, Harris said.
“You don’t have to water your lawn for at least a week,” he said.
