Change of plans: Light snow just might fall on the Metroplex Saturday night, but freezing temperatures will definitely prevail tomorrow -- the first day of spring.
A robust Canadian cold front, which was dumping snow over the Rockies Friday, is expected to plow into North Texas around sunup Saturday.
Its highlights will be an 80 percent chance of cold rain showers, near-freezing temperatures and powerful winds.
But don't fret. Normal spring-time temperatures are on tap for next week, said Ted Ryan, meteorologist with the National Weather Service in Fort Worth.
"This cold system will be in and out pretty quickly," Ryan said, "but it's going to pack quite a punch."
Forecasters were not sure on Thursday if the storm system would track south enough to produce snow in North Texas.
That changed on Friday.
"We're looking at some new data coming in," said Ryan said around noon Friday. "It looks like its going to come a little farther south than we expected."
Light snow, therefore, is possible Saturday afternoon and evening in the Metroplex, Ryan said.
"Right now it doesn't look like it will be heavy enough for any significant accumulation problems," he said. "But, farther north along the Red River, it looks like there might be some accumulations there."
The vernal equinox, according to the weather service, will be at 12:32 p.m. Saturday.
But while the updated forecast calls for a high temperature of about 53 degrees -- most of Saturday will be about 20 degrees colder.
The high temperature, Ryan explained, will be recorded before sunup -- before the arrival of the winter storm system.
"The cold front comes marching through right around sunrise and temperatures will start falling into 30s," Ryan said. "They're going to be staying there pretty much all day tomorrow."
A "big area of rain" will coincide with the cold front's arrival, along with sustained winds of 20-30 mph and possible gusts at 40, Ryan said.
The rain and thunderstorms aren't expected to be severe, but the winds will stay around all day, Ryan said.
There will be a break in storms around 1 p.m., Ryan said, followed by possible light showers.
But, he noted, if there is enough moisture in the area late Saturday afternoon and evening, there could be some light snow.
Gardeners who planted early should cover their plants, Ryan said.
