NWS Jackson, MS wrote its last area forecast discussion before the first event at Jul 22, 10:51 AM CST, 1 hour 6 minutes earlier.
Area Forecast Discussion National Weather Service Jackson MS 1151 AM CDT Sat Jul 22 2023 ...New MESOSCALE UPDATE... .MESOSCALE UPDATE... Issued at 1151 AM CDT Sat Jul 22 2023 Rest of today... Morning 12Z upper/water vapor analysis indicates longwave trough centered over the Great Lakes with the axis extending to the south, with the trough axis just to the west of the region. Favorable upper jet dynamics/diffluence in advance of another perturbation progged to move into the Mid-South this afternoon in northwest flow will help increased ascent persist across the southern half of the area. Earlier morning shortwave has departed to the east, with decreased ascent & rain chances across the northern half of the region. Morning sfc analysis indicates frontal zone draped south of Interstate 20, with continued convergence & pooling moisture along & south of the boundary. This is evident in increased agitated cumulus field south of Interstate 20. This is combined with nearly 2 inch PWs for rain & storm potential into early to mid afternoon. Severe storm potential will persist into the afternoon hours. Unidirectional shear profiles & mean bulk shear around 25-30kts in the low-mid levels combined with some steep lapse rates/vertical totals around mid-upper 20s degree C & moderate destabilization will favor efficient cold pool development & some hail up to quarter size. Main concerns will be for multicell clusters or bowing segments, especially any that propagate east- northeast more orthogonal to the low-level flow. SPC added a Slight area, which seems reasonable. Morning sfc modified soundings indicate deeply unstable air favorable of microburst wind potential & this looks to be realized in regional mesoanalysis of nearly 5000 J/kg SBCAPE. Timing will be early afternoon into the evening hours. In addition, HREF indicates potential for some heavy rain & increased neighborhood probs/max of > 3 inches in the Hwy 84 to I-59 corridor. Added a "Limited" in the HWO in southeast MS along & southeast of a line from southern Lawrence County to central Clarke County. Backbuilding doesn't look to be a concern but efficient heavy downpours/training look probable. Highs will remain less oppressive north of I-20 but compressional warming & continued warm thermo south of I-20 will help aid in temperatures peaking into the mid 90s especially in the Hwy 84 corridor. With high PWs & limited mixing, sfc dewpoints remain the mid-upper 70s. Dangerous heat stress remain a concern into the afternoon, with some areas in the Pine Belt currently reaching Heat Advisory criteria. Heat Advisory/HWO look on track & no changes were needed at this time. /DC/ && .DISCUSSION... Issued at 359 AM CDT Sat Jul 22 2023 Today through tonight: A cold front pushing south across the area will bring a marginal risk for severe weather, and it will help suppress the significant heat stress conditions to along/south of the Highway 84 corridor where a heat advisory will continue for today. A weak shortwave trough is helping to generate numerous showers and thunderstorms over mainly north central Mississippi early this morning. The convective rainfall will continue for the next several hours before diminishing later this morning as the minor trough exits. Then expect redevelopment of storms this afternoon for locations mainly south of the I-20 corridor, where most unstable CAPE > 3000 j/kg combined with ~30 kt mid level flow will support a few severe multicell storm segments. Storms should diminish early this evening with cooler and less humid air conditions expected overnight. /EC/ Sunday through Friday: On Sunday, the cold front associated with a upper level trough will stall out along the Gulf Coast. Rain chances will remain along the Gulf Coast through Sunday night as the trough gradually makes its way east. Temperatures will be relatively cooler during this period as highs will be in the low 90s and lows with be in the upper 60s across the area. By Tuesday, the trough will have made its way east of the area and the upper level high that was giving us problems earlier this week will make its back eastward. 500mb heights will increase, bring warmer conditions back to the region by midweek. High temperatures during this period will be in the mid 90s. Dew points in the high 60s will suppress some of those extreme heat indices we experienced earlier this week, but heat indices ranging from 100-105 can still be expected in some areas. By Thursday, ridging from the high pressure system will begin to weaken off to our west. The chance for scattered diurnally driven storms will increase areawide heading into the weekend. /LCP/ && .AVIATION... (12Z TAFS) Issued at 645 AM CDT Sat Jul 22 2023 Convective precip continues along/ahead of a cold front, and this will likely continue for the next few hours in northern portions of the area. IFR/LIFR category stratus has developed and could impact most sites early this morning before lifting/dissipating by late morning. Expect another round of SHRA/TS to develop this aftn across southern portions of the area. Otherwise, VFR conditions and light surface wind will prevail through this evening. Another round of low stratus may impact the area late tonight into early Sunday morning. /EC/ && .PRELIMINARY POINT TEMPS/POPS...
