Central Texas could see record low temperatures over the next three days.
Meteorologists at the National Weather Service in Fort Worth have forecast Monday, Tuesday and Wednesday night temperatures to drop as low as 65 degrees, 59 degrees and 64 degrees, respectively.
Tuesday night would be the first time temperatures dip into the 50s (in July) in more than 100 years, said Dennis Cavanaugh, meteorologist at the NWS.
"If the forecast actually happens that would set a record low for any day in July," Cavanaugh said.
The coolest temperatures occur just before sunrise, he said.
Daytime temperatures also are expected to remain in the low 90s today, Tuesday and Wednesday.
The cool weather is a consequence of an unusual upper-level low pressure system and consistent north wind, bringing dry air from the Central U.S.
"The dry air cools off faster overnight than the humid air," Cavanaugh said.
