Red in the morning....
Last day of the heat wave? That's the prediction from the National Weather Service. Which means the crimson sunrises and sunsets, the daytime sky the color of old mayonnaise, may be on the way out, too.
The highs for Wednesday are expected to linger in the mid-90s before dropping into the low-70 for the remainder of the week and weekend.
Air quality was moderate on Monday and Tuesday after it reached unhealthy levels on Sunday.
The National Weather Service said that hazy conditions will increase as "flow aloft turns more north-northeasterly," carrying wildfire smoke from both British Columbia and Washington into the metro area.
Air in Northeast Portland is "unhealthy for sensitive groups." The rest of the area is seeing "moderate" air quality, but that's expected to deteriorate in the coming days.
An Air Quality Advisory has been issued for parts of southwest Washington, Portland, Oregon North Coast and much of the Willamette Valley, including Washington County.
