DISCUSSION

Issued at 220 AM CDT Sun May 10 2026

Several observation sites have dropped to <1/4 mile visibilities as dense fog continues to develop around the region, thus a Dense Fog Advisory has been issued through 9am Sunday morning.

Conditions will start off quiet early Sunday morning as areas of dense fog persists across our area. The fog should begin to lift and dissipate by mid-morning. Attention then turns to a cold front that will move south across our CWA late Sunday afternoon, supporting the development of isolated showers and thunderstorms. While low-level shear doesn't look the best, there is enough deep layer shear ahead of the front that any storms that interact with this environment will have the chance to reach severe criteria. In order to accommodate this development, the "Slight" risk (Level 2 out of 5) for severe storms has been expanded further eastward towards the I-55 corridor for late Sunday afternoon/Monday morning timeframe . Likewise, a "Marginal" risk (Level 1 out of 5) for isolated strong to severe storms will continue to be advertised across the remainder of the area. Primary hazards will be damaging winds and hail up to quarter size.

In addition to the severe wx potential, some of these storms will have the potential to produce locally heavy downpours at times. With PWATS near 1.5 inches and some storms producing isolated high rain rates over waterlogged areas, the "Limited" threat for flash flooding will continue to be advertised for areas along and south of I-20 heading into Sunday night. /CR/KP/

Monday morning through Saturday...

Storm chances should start to diminish by late Monday morning/early Monday afternoon as the cold front continues to push southward towards the Pine Belt. Rain chances will come to an end Monday evening as the cold front finally exits our area and continues its southward track towards the Gulf. Monday night and Tuesday night's lows will be the coolest with nighttime lows int upper 40s/lower 50s. Quiet weather conditions will persist across the southeast CONUS though the weekend with daytime highs peaking in the mid 80s. /CR/

A mix of VFR/MVFR/IFR/LIFR conditions prevail at TAF sites and expect most sites to become IFR/LIFR over the next few hours, as fog/stratus continue to develop across the area. Expect the fog/stratus to dissipate by mid morning, with sites becoming VFR for much of the remainder of the period. Showers/storms may develop late in the period out ahead of a cold front./15/
