DISCUSSION

Issued at 1151 PM CDT Sat Aug 22 2026

A northwesterly upper-level flow pattern is in place across the local area as an upper ridge builds over the Rockies and upper troughing digs over the Great Lakes region. This general pattern is expected to continue through the week, allowing for several embedded shortwaves to push into the area from the northwest. The first of these shortwaves is currently passing across the Lower Mississippi River Valley. Forcing from this shortwave helped to spark off a complex of storms which moved through north/central MS and AL this past evening. As we go through the rest of the overnight hours, outflow from these storms will push southeastward, likely reaching our coastal counties by the mid to late morning hours. Additionally, as the aforementioned shortwave passes overhead, guidance now suggests that it will help to push deep moisture (PWATs around 1.8-2.1 inches) into the area. It should be noted that this is a rather stark difference to what guidance was showing 24 hours ago. What this means is that we appear to be trending wetter for Sunday afternoon, particularly over the southern half of the local area where the remnant outflow boundary and sea breeze boundary serve as a focus for showers and storms to develop along. PoPs across the southern half of the area now range from 30-50%, with PoPs around 20% further inland. Although shear is weak, the highly unstable environment in place (SBCAPEs exceeding 3000 J/kg and DCAPEs up to around 1000 J/kg) could support a few strong to severe pulse-type storms, capable of producing gusty to damaging winds. A Marginal Risk of Severe Weather is in place for locations south of Highway 84. Activity will diminish by the evening hours.

Rain chances increase even further on Monday and throughout the week as several more shortwaves push into the area within the northwesterly flow pattern aloft. Scattered to numerous showers and storms are expected to develop each afternoon, with the highest coverage expected over coastal counties as storms initially develop along the sea breeze and spread via outflow boundary collisions. Strong daytime heating will also lead to high instability which could support the development of a few strong to severe storms capable of producing gusty downburst winds and small hail, along with frequent cloud-to-ground lightning and very heavy rainfall. Additionally, as we often see whenever we have a northwesterly flow pattern this time of year, we will have to keep a close eye on if upstream storms are able to organize into an MCS and push into our local area. If an MCS is able to develop and impact our area, then we could see an increased risk for damaging winds. We will monitor trends closely over the coming days.

Very hot conditions are expected on Sunday, with highs topping out in the mid to upper 90s. A Heat Advisory has been issued for our southeast Mississippi counties for Heat indices of around 108 degrees. The good news, though, is that with the increase in rain chances throughout the week, temperatures will fall back to their seasonal norms, with highs by midweek in the upper 80s to low 90s. Heat indices throughout the rest of the period should generally remain just below Heat Advisory criteria (around 102-107), although a few localized spots of 108-110 degrees cannot be ruled out. Lows will range from the low 70s inland to the upper 70s along the coast. A Low Risk of rip currents remains in place through the week. /96

AVIATION
