DISCUSSION
KEY MESSAGES:
- Smoke continues to impact the region, though the areas most impacted shift south.
- Warming, drying trend continues through the week.
- Breezy conditions at the end of the week pose a fire weather risk starting Friday.
High resolution models continue to show smoke impacts for the region, though conditions will improve slightly. Wildland fires upstream in Washington and Oregon have been less active the last couple of days, and as a result there is less smoke being produced. Also, a northerly component to the wind means that the more concentrated smoke will be focused more to the south, mainly south of I-90. That being said, local fires are still producing smoke, so no area is really in the clear.
The warming and drying trend continues through the week with Friday expected to be the hottest day of the week. Models are agreeing on a flattening of the ridge over the region late Friday into next weekend. This will proved some relief from the hot temperatures, and increased breezes will help ventilate some smoke out of the region. However, the breezy conditions are also a concern for wildland fires, especially after a long, hot, dry week.
AVIATION
A ridge building over the area is causing hot, dry, and stable conditions. While this is exasperating the smoke problems, upstream fires have been producing less smoke recently, so that helps a little. Even with the smoke in the area, VFR conditions are expected at area terminals through the rest of the week.
