Riverton, WY – Residents across Fremont County and central Wyoming face a week of mild afternoons followed by sharply colder nights, creating temperature swings approaching 30 degrees.
According to the National Weather Service in Riverton, daytime highs should remain near 60 degrees through Tuesday, Nov. 10, before easing slightly around Veterans Day.
The most noticeable change comes Wednesday night, when temperatures are expected to fall to approximately 30 degrees.
That is a 31 degree difference from Tuesday's projected afternoon high.
Monday and Tuesday Bring Warm November Afternoons Monday, Nov. 9, should bring partly sunny skies and temperatures near 60 degrees.
Light and variable winds will help keep conditions comfortable for outdoor activities.
However, Monday night brings mostly cloudy skies and a low around 32 degrees.
Tuesday, Nov. 10, offers another mild afternoon, with mostly sunny skies and a high near 61 degrees.
Southwest winds around 5 mph should become light and variable during the morning.
By Tuesday night, temperatures fall to approximately 31 degrees.
Residents enjoying the afternoon warmth should remember that temperatures can drop quickly after sunset.
Veterans Day Brings Sunshine and Another Freeze Wednesday, Nov. 11, Veterans Day, should remain sunny across Riverton, with afternoon temperatures reaching approximately 57 degrees.
Calm winds are expected, creating generally favorable conditions for outdoor ceremonies and community gatherings.
However, temperatures are expected to fall to around 30 degrees Wednesday night.
That marks the coldest projected reading in the immediate five day outlook.
Anyone attending early Thursday activities should prepare for freezing temperatures, particularly in exposed and low lying locations.
Could Freezing Temperatures Affect Riverton Roads? Drivers traveling U.S. Highway 26, U.S. Highway Riverton area routes and roads connecting nearby Fremont County communities should remain aware of colder morning conditions.
Temperatures near 30 degrees can allow existing moisture to freeze on exposed pavement.
Bridges, shaded roads and untreated surfaces deserve additional attention whenever moisture is present.
However, the supplied National Weather Service forecast does not indicate accumulating snow, freezing rain or a widespread icy road event through Saturday.
For now, dry weather remains the dominant pattern.
Thursday and Friday Keep the Mild Pattern Going Thursday, Nov. 12, brings another sunny afternoon, with highs reaching approximately 58 degrees.
Thursday night temperatures fall to around 32 degrees, maintaining the pattern of freezing or near freezing mornings.
Friday, Nov. 13, should warm to approximately 60 degrees under mostly sunny skies.
Friday night remains mostly clear, with temperatures around 33 degrees.
Saturday, Nov. 14, offers another mostly sunny afternoon near 60 degrees.
This extended stretch of dry weather may provide opportunities to finish fall yardwork, clear fallen leaves and prepare outdoor equipment before colder winter weather eventually arrives.
Although snow becomes an increasing seasonal consideration as Thanksgiving approaches, no specific snowstorm is identified in Riverton's supplied forecast.
