SHORT TERM /THROUGH THURSDAY NIGHT/

Issued at 300 AM MDT Wed Jun 10 2026

Current surface observations show breezy conditions across most of southeast Wyoming with yesterday's cold front well to the south and east...moving into central Nebraska and northwest Kansas at this hour. Pretty nice day today, but winds are expected to increase across the whole area through the late morning and afternoon hours with gusts of 45 to 55 MPH expected for southeast Wyoming, and 35 to 45 MPH for western Nebraska into this evening. High temperatures will be cooler compared to yesterday, but still slightly above average with highs in the 70s along and west of Interstate 25, and in the 80s east of I-25 into western Nebraska. A High Wind Watch remains in effect for the wind prone areas of southeast Wyoming. Winds have been tame so far this morning with only one or two gusts up to 53 MPH briefly behind the cold front. Will leave the Watch as is and continue to monitor trends and observations. In-house wind guidance continues to show probabilities between 35% to 50%. Again, winds are expected to increase late this morning with daytime mixing, but not totally confident the wind prone areas will see persistent gusts over 58 MPH this time of the year.

Similar conditions for Thursday as another cold front will move southeast across the area. Remaining breezy with winds shifting into the northwest Thursday morning. It will be a few degrees cooler with temperatures closer to average/slightly below average for this time of the year (low 70s to low 80s). Other than a few showers across central Wyoming with FROPA, dry conditions will continue through Thursday night.

LONG TERM /FRIDAY THROUGH TUESDAY/

Issued at 157 PM MDT Tue Jun 9 2026

A continuation of elevated fire weather conditions will likely spill over into Friday. Overnight recoveries are poor at 35- 50 percent along the foothills and basins. Afternoon humidities may plummet into the single digits area wide. Winds look concerning over the basins where gusts of 25-40 mph will exaggerate fire conditions when combined with the very low humidities. Temperatures also are a little toasty with a good portion of the Nebraska Panhandle reaching the 90s.

Saturday features a return flow with southeastern winds. There may be enough moisture with this return flow to alleviate critical fire conditions, though they remain elevated. A few storms could develop in the southern parts of the CWA and spreading into the mountain basins Sunday and Sunday. There is not much of a signal for severe weather in the long term. Between Sunday and Monday a cold front may push its way through, though at this range there is considerable spread in timing.

AVIATION /12Z TAFS THROUGH 12Z THURSDAY/

Issued at 545 AM MDT Wed Jun 10 2026

Another dry cold front is expected to push across the area tonight. Breezy to windy conditions expected over the next 24 hours with some diurnal variations in wind speed between 02z and 12z.

HAZARDS/WEATHER TRENDS: VFR conditions will prevail with mainly a wind forecast for all terminals. Winds will quickly increase early this morning with gusts between 35 to 45 knots for southeast Wyoming terminals after 14z, and 30 to 40 knots for the western Nebraska terminals after 14z-16z. Winds will be slow to subside late this evening.
