Major, prolonged arctic outbreak: Frigid temps, light snow by Tuesday
A major prolonged arctic outbreak is on the way for the area beginning by Tuesday, bringing dangerously cold weather and light snow through the rest of the week.
Tim Trudel, a meteorologist with the National Weather Service in Cheyenne, said that Monday will be last nice day as very warm and windy conditions will push highs to near 60. By Wednesday night, Trudel said, lows could plummet some 80 degrees colder.
The sharply colder air will arrive Tuesday, with morning temperatures in the 30s falling to the teens by the afternoon. Trudel said that the weather will get progressively colder throughout the week.
By Wednesday and Thursday, highs in the area may not reach 10 degrees, and lows could plummet as low as 10 to 20 degrees below zero. Winds, although light, may push wind chills colder than 30 below both Wednesday and Thursday nights.
Trudel said that although there will be a prolonged period of snow, when temperatures are that cold, it will be difficult for the snow to accumulate.
Trudel urged stock growers to take necessary actions to protect their newborn livestock from the frigid weather by Monday. He said that they are very confident the cold air would arrive, and the only questions remaining is if that cold air will hold any moisture to cause snow to fall.
Asked how confident the weather service was about the arctic outbreak, he said "About 100 percent. We can't avoid this cold weather."
