KEY MESSAGES

- Cloud cover clears east of the Continental Divide during the midday hours today, allowing for daytime high temperatures to rebound 5 to 10 degrees. Areas west of the Divide see little cloud cover and seasonal temperatures.

- Temperatures rebound to seasonal normals across the entire region Monday before warming several more degrees Tuesday.

- Limited to no rain chances along with the warm temperatures and increasing west wind leads to elevated to critical fire conditions much of the week. Tuesday looks to be the most critical as westerly wind blows 20 to 35 mph.

DISCUSSION

Issued at 223 AM MDT Sun Jun 14 2026

Areas east of the Divide were abnormally chilly yesterday for mid- June. The overall forecast verified quite well, although portions of Johnson and Natrona counties stayed in the 40s through much of the day, finally reaching the upper 50s by 6PM. The 0.49" of rain that was forecasted in northern Johnson County between 12Z and 18Z also verified, with KBYG receiving 0.47". The cold front continues its eastward progression, finally reaching the UT border around 06Z Sunday. Gusts of 25 to 40 mph will continue across portions of Sweetwater and southern Sublette counties for the next few hours, subsiding through 15Z.

Seasonal to slightly below normal temperatures will be in place across the CWA today with highs in the upper 60s into the 70s. Conditions will be dry, except for very isolated showers possible from the southern end of the Absarokas to the southern end of the Bighorns throughout the day. Winds will be light as well, with gusts up to 20 mph occurring over southern portions of the forecast area.

A warming trend will begin Monday, with a northwest flow pattern aloft in place. Conditions will be dry, with highs near 80 degrees returning across the CWA. Any chance for a shower could occur over the northern half of the Bighorns and northern Johnson County late in the afternoon. Heights will rise Tuesday within this northwest flow pattern, leading to high temperatures in the upper 80s to lower 90s in the Wind River and Bighorn Basins and portions of Natrona County. Temperatures will be slightly cooler east of the Divide Wednesday, as a cold front clips northern portions of the state. This looks to be the best chances for any precipitation next week as well, as much of the week looks to stay dry. Fire weather conditions will be elevated to critical through the week as well, with Tuesday looking to be the most critical. Fuels are currently critical for portions of Natrona County and a Fire Weather Watch looks likely here.

West to northwest wind 7-11kt returns to all terminals between 19Z-22Z/Sunday. Another surge of northeast wind 10-15kt pushes through KRKS around 00Z/Monday.

East of the Divide...KCOD/KCPR/KLND/KRIW/KWRL Terminals

BKN-OVC ceilings at 040-070AGL prevail overnight as favorable northerly flow and mid-level moisture remain across the region. VFR conditions should prevail, although there is a 15 percent chance of MVFR in the upslope-favored basins, mainly at KLND. A secondary shortwave sweeps northwest-to-southeast through the region during the midday hours Sunday allowing for the cloud cover to scatter out. North to northeast surface wind 7-11kts will be common. Mountain tops frequently obscured through 18Z/Sunday.
