Cheyenne, WY – Gusty winds and very low humidity across the northern High Plains Saturday could elevate localized wildfire risk.
According to the Storm Prediction Center (SPC), a strong cold front moving east across the Midwest and Plains will bring cooler air and high pressure behind it, limiting fire concerns across much of the central and eastern United States. However, parts of central and eastern Wyoming and nearby areas of Nebraska and South Dakota may experience conditions more favorable for fire spread.
Meteorologists say a clipper low moving across the Canadian Prairies will strengthen west to northwest winds during the late afternoon hours. Sustained wind speeds of 15 to 25 mph are expected across portions of the region.
At the same time, relative humidity levels may drop to 15% to 25%, particularly in downslope wind areas of central and eastern Wyoming. When combined with dry fuels and recent limited rainfall, these conditions can increase the potential for grass or brush fires to spread quickly.
The SPC notes that east-central Wyoming and adjacent parts of Nebraska and South Dakota may see the greatest concern, as fuel dryness values in those areas are currently near seasonal highs and precipitation during the past several days has been limited.
Elsewhere in the country, widespread rain and cooler temperatures from the Ohio Valley into the lower Mississippi Valley are expected to keep fire risk low.
Meanwhile, Southern California’s coast may see east to northeast winds of 15 to 25 mph with gusts reaching 35 to 45 mph through early Sunday due to offshore flow. However, forecasters say vegetation in that region currently remains too moist to support significant fire spread.
Drivers and outdoor workers across the High Plains may notice stronger winds Saturday afternoon, which could also affect visibility and travel for high-profile vehicles.
