After a calm and pleasant Saturday, residents in Riverton and nearby areas should prepare for changing weather as thunderstorms are expected to develop Sunday afternoon. The National Weather Service has warned that these storms could bring heavy rain, lightning, and strong winds, especially along U.S. Highways 20 and 26. The risk of thunderstorms will increase through the week, with Wednesday and Thursday looking most active.
Thunderstorms to Begin Sunday Afternoon
Starting Sunday afternoon, scattered thunderstorms are likely to build across central and western Wyoming. These will begin as isolated showers but could grow stronger by the evening, especially around Riverton and surrounding towns. Rain may be heavy at times, and lightning could be frequent.
Outdoor activities, especially in popular areas like Yellowstone and the Wind River Range, may be disrupted. If you’re planning to hike, camp, or travel on mountain trails, it’s best to check the weather before heading out and avoid exposed areas during storm hours.
Increasing Storm Chances Through Midweek
The start of the week brings continued storm chances, with each afternoon likely to bring some level of thunderstorm activity. Communities stretching from Casper to Rock Springs should stay alert as conditions may change quickly.
Some key points to keep in mind:
Monday and Thursday are expected to have the most active storm systems
Localized flooding is possible in areas with heavier downpours
Power outages could happen where storms are stronger
Lightning and wind gusts can impact travel plans
If you’re driving in rural areas and notice skies darkening, it’s safer to pull over until the storm passes. Reduced visibility from heavy rain can make highways dangerous.
Temperature and Conditions for the Week
Despite the daily storm chances, temperatures will remain fairly steady, ranging from the upper 70s to low 80s. While not extremely hot, the unsettled weather means outdoor conditions will be unpredictable and often wet.
Weather Alerts and Community Support
Weather spotters in Fremont County are encouraged to report any major rainfall, wind damage, or flooding to help the National Weather Service track storm severity. Residents are also advised to keep mobile devices charged and check weather updates regularly. Additional alerts may be issued as storm patterns become clearer through the week.
