VICTORVILLE — Cooler temperatures hit the High Desert this week, with the threat of rain looming Wednesday and Thursday.
After the National Weather Service issued a flash flood warning for the High Desert Wednesday night, rain is less likely on Thursday.
Thursday is expected to be mostly sunny with a high of 89 degrees. Thursday evening is forecasted to be cloudy with a low around 63 degrees.
A slight warming trend is expected for the rest of the week, with temperatures reaching into the low 90s Friday and throughout the weekend.
Phelan-based weather spotter Tom Fracasso said the low pressure system responsible for the wet, cool weather is coming from Northern California and the Pacific Northwest and is also bringing below-average temperatures to the area.
“This system has been really complex; the computer models have been all over the place,” Fracasso said. “There was a high pressure system from Arizona and this low-pressure from the Pacific Northwest and it was kind of a contest to see which would win.”
He said the fact that the system is coming from Northern California instead of from the normal location near the Gulf of California is bringing the cool weather and threat of storms.
“This is like fall weather,” Fracasso said on Wednesday. “It’s definitely an anomaly to have thunderstorms in August with these low temperatures.”
He said that high temperatures in Phelan dropped from 97 degrees on Monday to 84 on Tuesday. The National Weather Service reported the high for Victorville dropped from 98 degrees on Monday to 90 on Tuesday.
