KEY MESSAGES

Issued at 618 AM CDT SUN AUG 23 2026

- Heat: Minor to moderate heat risk will continue through the upcoming week. Heat indices are forecast to remain below 105 degrees.

DISCUSSION

(Today through Saturday) Issued at 1206 AM CDT SUN AUG 23 2026

There are a few lingering showers on the radar from earlier storms albeit decreasing in coverage after an evening of storms and gusty winds across the northwest third of the area ahead of a surface boundary. This boundary is expected to progress southward tonight into early Sunday before stalling across the southern third of Alabama. It is expected to meander in that area through the short term through early Tuesday. In the upper levels, a low is present over Ontario and Quebec and southward into the Great Lakes and much of Eastern Conus. At the same time, there is also a large ridge over New Mexico. This leaves Central Alabama in an at times active northwest flow regime. Look for isolated to scattered waves of convection at times through Monday. On Tuesday, the surface boundary is expected to meander back northward before fizzling out on Wednesday. However, the northwest flow will assist in another front making it into the area in the Thursday/Friday time frame. This will keep unsettled conditions along with scattered slightly higher storm chances in through the latter part of the forecast as moisture increases.

Through the 7 day forecast, a few upper lows rotate through the current trough area over Eastern Canada and the Great Lakes with varying degrees of southward progression into Eastern Conus, but overall some degree of troughing remains. Our Southwest US ridge remains as well. The only difference will be a progression of surface boundaries. While the lower dew points have been nice. Look for those to rise through the week. However, overall temperatures should be a tad lower with the increased rain chances and progression of the boundaries and enough to keep chances low for needing a heat advisory over the next week if guidance continues this trend. With that said, it is August in Alabama and still hot, just not as hot as the past couple of weeks.

FIRE WEATHER

Drier air filtering into the area will result in a decrease in relative humidity (35 to 45%) for most locations on Sunday. However, wind speeds are expected to remain light, which should negate any significant fire weather concerns. Moisture gradually begins to return on Monday and into the week.
