Overnight temps in NW Wyoming fell to -37 degrees

Cold enough for ya?

If not, consider a weekend getaway to Yellowstone National Park.

The Grant Village reporting station (at the west end of Yellowstone Lake) measured -37 degrees just after sunrise on Thursday. A measured 3 MPH wind at 7:35 AM at that location equates to a wind chill of -50!

County 10 meteorologist Dave Lipson explains that ‘temperature lag’ is the reason the coldest time of any 24 hours is often just after sunrise.

“The amount of incoming solar radiation is very low when the sun is lower on the horizon. As the sun gets higher in the sky, the incoming solar radiation overcomes the outgoing terrestrial radiation, and that’s when the temperature begins to rise,” Lipson says.

Two reporting stations near the south entrance of Yellowstone National Park also registered -34 degree air temperatures this morning.

In Fremont County, temperatures at Little Wind River dropped to -10.

-7 was measured in Ft. Washakie and Shoshoni.
