- A marginal risk (level 1 out of 5) for severe thunderstorms across the western and southern portions of Central Alabama for late Sunday into Monday. Threats include damaging wind gusts and large hail.

DISCUSSION

(This afternoon through Friday) Issued at 1224 PM CDT SAT MAY 9 2026

Water vapor imagery reveals a shortwave rotating along the northern Gulf coast. Lift associated with this feature and a stalled boundary along the coast are currently driving a cluster of showers and storms across the southern half of the state. This activity will continue to move south and east through the early afternoon hours. Additional bouts of upper level energy will stream across the region through the weekend leading to low chances of additional showers and storms this afternoon and again on Sunday. Otherwise for tonight, there is a moderate (40-60%) chance for patchy fog to develop across the region. Best chances are for those that saw plentiful rainfall earlier this morning. RAP guidance is indicating a swath of condensation pressure deficits from 0-3mb along with narrowing dew point depressions. This could lead to a few isolated pockets of dense fog before sunrise Sunday.

As we head through the day Sunday, an upper trough will swing across the northern Plains towards the Great Lakes region. An associated cold front will head our way late Sunday into Monday morning. Moisture pooling ahead of this boundary will contribute to another round of showers and thunderstorms. The latest CAMs are hinting at a bit more instability, generally across the southern half of the CWA, which would help support a few strong to marginally severe storms Sunday night into Monday morning. As a result, our southern half of the CWA remains under a Marginal Risk (Level 1 out of 5) for severe storms as we head into the work week. The main threats will be damaging winds and large hail.

Drier conditions are expected in the wake of the front as surface high pressure and northwesterly flow aloft take control. A few H5 ripples look to traverse the region through the work week. However, moisture recovery will not be sufficient enough to warrant any mention of showers and storms at this time.

AVIATION

(00Z TAFS) Issued at 744 PM CDT SAT MAY 9 2026

Ceilings will deteriorate this evening as low level moisture increases with MVFR CIGS developing for most sites by 3z. CIGS will deteriorate further to LIFR from around 6-8z. There is a high confidence of patchy fog developing due wet grounds from recent rains. There is a medium confidence of this fog becoming dense going to below 1SM after 8z and lasting through sunrise. Low cigs will linger during the morning and are not likely to go back to VFR until after 18z for most sites. There are low rain chances during the period, but are too low to mention in TAFs at this time. Better chances are Sunday night ahead of a front.

FIRE WEATHER

Continued rain chances through the weekend will help keep min RH values generally above 50%. Drier air returns late Monday in the wake of a cold front with min RH values falling to 30-40% by Tuesday afternoon. Fire weather concerns are not expected over the next several days.
