Great Weekend Weather for Wyoming

Warmer and drier weather will move into Wyoming on Friday and Saturday.

Rain chances increasing

Wyoming’s weather will be very close to normal in regards to temperatures and conditions as high pressure is now well established across the region. Expect warm to hot days and mild nights. There will be a handful of isolated to widely scattered afternoon and evening thunderstorms some of which will cause strong and gusty winds. Warm temperatures, partly cloudy skies and late day thunderstorms can be expected all week and into the weekend.

Temperatures set to sizzle

Don Day — Fri, 16 Jul 2010 16:30:45 +0000

Some of the hottest temperatures of the year will develop across Wyoming over the weekend as high pressure builds over the region helping to draw hot, dry desert air into the Rockies. Temperatures will range from the upper 80s to the upper 90s on the plains with 70s and 80s in the mountains. A few 100s will be possible in far eastern plains (Torrington, Wheatland, Pine Bluffs). Only a few isolated thunderstorms are expected over the weekend. The thunderstorms will produce more wind than rain.

Warming up

Don Day — Thu, 15 Jul 2010 14:37:56 +0000

A classic mid summer weather pattern will develop across Wyoming over the next several days and well into next week. Temperatures will rebound into the 80s and 90s on the plains with 70s and 80s in the mountains and high valleys. Thunderstorm chances will be low through Friday but a few isolated thunderstorms will develop this weekend.
