GILLETTE, Wyo. — Smoke and haze from wildfires burning to the west are drifting eastward, impacting air quality in northeastern Wyoming and far-western South Dakota. These hazy conditions are expected to persist through Tuesday in Gillette, the National Weather Service in Rapid City, South Dakota, said.
A high-pressure system currently centered over the Midwest is bringing southerly and southeasterly winds, which are carrying smoke from the wildfires. This system will also contribute to warmer temperatures and dry conditions, increasing fire danger this week, meteorologists said in the forecast discussion.
A cold front is expected to move through the area Thursday, bringing a shift in wind direction. Despite this front, very warm and dry conditions are predicted to persist into next week, with little chance of significant rainfall.
Areas of smoke are expected today in Gillette as the high reaches 76. Skies should be mostly sunny. There will be a northwest breeze at 5–7 mph. The smoke will continue to remain heavy through tonight and into Tuesday. The low tonight will be near 44.
