FORT WORTH -- Perhaps you're going to Saturday night's match-up between the Cowboys and the Baltimore Ravens, and you are considering a memento from the final regular season game ever at Texas Stadium.
May we suggest a commemorative hooded sweatshirt? Go with the really heavy one, because you're going to need it.
Saturday will be mostly sunny with a high around 70 degrees, according to the National Weather Service.
But watch out because by the end of the game -- kick off is 7:15 p.m. -- an arctic air mass will have pounced on the Metroplex, the weather service said.

"Saturday evening, around 7 o'clock, it will still be warm," said Jason Dunn, a weather service meteorologist. "But, by the end of the game, it's going to be cold.
"It will probably be in the 30s, but the winds will be pretty strong again -- about 15-25 mph -- which will bring the wind chill down to the 20s."
It will be a near repeat of last Sunday, when balmy weather was supplanted by an arctic front that left vast areas of dense fog in its wake, Dunn said.
But the difference here will be a lack of moisture, even though the latest arctic front is the same weather system that dumped a 3 inches of snow earlier this week on Las Vegas.
"It's going to be quite a bit drier behind this system," Dunn said. "We won't see any moisture until Tuesday, after we have some southerly winds starting on Monday.
Meanwhile, he added, it will be frigid.
"Sunday will be sunny and cold -- around 30 degrees -- and winds will be back up around 15-25 mph," Dunn said. "It will be the same on Monday, but clouds will come around late in the day with southerly winds.
"We'll have a 40 percent chance for rain on Tuesday."
The sun returns Wednesday and Thursday -- Christmas Day! -- with temperatures ranging from the high 50s to the low 60s, the weather service said.
