After several sweltering weeks, a refreshing three-day cool spell has moved into Central Texas.
Meteorologists at the National Weather Service in Fort Worth forecasted nighttime temperatures Monday, today and Wednesday to drop as low as 65 degrees, 59 degrees and 64 degrees, respectively across the area.
Tonight would be the first time temperatures dip into the 50s (in July) in more than 100 years, said Dennis Cavanaugh, NWS meteorologist.
“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 are expected to remain in the low 90s today and Wednesday, in contrast to last week’s triple-digit readings.
The cooler weather is a consequence of an unusual upper-level low pressure system and several days of northerly wind, which has brought in dry air from the central United States.
In normal summer conditions, southerly winds bring humidity from the Gulf of Mexico, Cavanaugh said.
“The dry air cools off faster overnight than the humid air,” Cavanaugh said.
