Some campers woke up to white morning in the Bighorn Mountains in Northern Wyoming early Friday. A powerful late summer cold front front moved down in from Canada dropping temperatures 30+ degrees in a 24 hour period across the Northern Plains and Rocky Mountain Regions. The lows temperatures Friday Morning in many places approached 40 degrees but in the mountains above 8000 feet, temperatures dropped down in the low 30’s; cold enough to produce snow.
After a cold start to Friday, things didn’t get much better into the afternoon for the people of the Cowboy State. The 2nd biggest city in Wyoming, Casper, struggled to reach a measly 50 degrees. That was the coldest maximum high on record for the 19th of August for Casper. The old record was a high of 58 degrees in 1956.
The cold air Friday night will track southward into Southern Wyoming and Colorado. Several cities, including some non-mountain towns will drop down near freezing as as Frost Advisory has been issued into Saturday Morning in Southern Wyoming. Many places in Colorado will be waking up with temps dropping into the 30’s and even 40’s in the Denver Metro area.
The cooler weather will be hanging around for the start of the weekend for folks in the Mile High City, but temperatures by the end of the weekend will be back up close to normal with a 90 degree day coming back for Monday. Skiers and snowboarders, don’t get too excited yet.. but definitely something to look forward to as we get closer to wrapping up the summer.
