DISCUSSION

(This afternoon through Saturday) Issued at 1208 PM CDT SUN MAY 24 2026

A mid-level trough axis centered just to the west of Alabama will continue to promote deep southerly flow across the Gulf Coast region. High vertical moisture content along with lift from passing impulses within the trough, and weak to occasionally moderate instability, will cause multiple waves of showers and thunderstorms through the week.

Forthcoming high rainfall rates, on top of already accumulated rainfall, will pose a risk for isolated flash flooding over the coming days. Today's threat seems most focused from near Birmingham to points northeast and east. This is due to a compact area of low pressure moving across central Alabama today, providing a focus and enhancement of heavy rainfall, which is modeled to fill in as it begins to impact urban and terrain areas across the aforementioned axis. While a relative lull is expected tonight (activity becoming more isolated), another batch of heavy showers and thunderstorms is expected on Monday; this may require either an extension of the current Flood Watch or the issuance of a new one, especially if a favored corridor of heavy rainfall can be pinpointed amongst the scattering of activity.

Deep-layer flow is on the weak side through the week, though any periodic enhancement timed with peak instability and/or outflow could pose a low risk for thunderstorms with gusty winds. For today, a level 1 out of 5 risk for severe thunderstorms with damaging wind gusts is highlighted for areas along and east of Interstate 65, though this threat is being hampered by widespread cloudiness and precipitation.
