Springtime in the Rockies

Springtime in the Rockies

After a  few false start, Spring Weather should make a real appearance  across Wyoming/Star Valley and surrounding areas the next couple weeks.  The longer range forecast is calling for above normal temperatures and drier than normal through the middle of May.

Forecast precipitation Friday May 11-Wednesday May 15 2018

 

Although forecast confidence is less, the indications are that the last half of May will also remain relatively drier and warmer than normal.
