Spring In Jackson, WY

The calendar has flipped to May, but the expected seasonal warmth is nowhere to be found across the likes of Wyoming.

The first day of May was unseasonably chilly in these parts. The month commenced with 10 inches of new snow in the Tetons above 9,000 feet (as of Wednesday afternoon). Even the town of Jackson saw heavy snow showers dust grassy surfaces.

A heavy snow shower dusts the town of Jackson on Wednesday, May 1.

The cold has been quite something, too, even for Jackson. Accompanying the snow, thermometers on Wednesday struggled to a high of just 38F (3.3C) setting a new record low-max for the date. Jackson's average high in early-May stands at 60F (15.6C).

Looking ahead, temperatures will remain well below average for the foreseeable, barring a one-day reprieve on Saturday when the low-60s are forecast.

On Sunday and Monday, a more potent low pressure system is expected to barrel into the region, resulting in more widespread precipitation, including significant mountain snow, along with another drop in temperatures.

Spring is refusing to sprung in these parts. Summer isn't looking much better either...
