Area Forecast Discussion...UPDATED National Weather Service Jackson MS 1254 PM CDT Mon May 15 2023 ...New AVIATION... .MESOSCALE UPDATE... Issued at 1117 AM CDT Mon May 15 2023 No major adjustments were needed to the going forecast, as forecast reasoning remains unchanged. A ridge of high pressure centered directly overhead means weak flow and minimal wind shear, but anticipated 90 degree temps over upper 60s/near 70 dew points should yield SBCAPE over 3000 J/kg over most of the area. Mesoanalysis and GOES Total Precipitable Water products show pockets of 1.5 inch PWATs around the forecast area, with some areas a little drier than that. Mid-level lapse rates are poor (<6 C/km). The combination of the marginally-supportive moisture levels and poor lapse rates will limit the chances for severe winds from microbursts today, and locally-derived microburst composite parameter off this morning's JAN sounding was '0'. A storm or two could become strong with gusty winds if the local environment overachieves the average. /NF/ && .DISCUSSION... Issued at 313 AM CDT Mon May 15 2023 Today and Tonight... What better way to start the week off with temperatures climbing into the 90s and dewpoints in the upper 60s. While temperatures in the 90s are hot, will take the upper 60s dewpoints vs the 70s. A surface high pressure centered directly over the ArkLaMiss region continues to amplify which is the reason for these hot conditions. Lows for tonight will also be generally warm with temperatures falling into the upper 60s and low 70s. Due to the influence of this surface high, rain and storm chances are less today than what we've seen over these last few days however, as we continue to transition into summer time pulse convection type patterns the chance for diurnally driven activity still remains. CAM guidance confine best rain chances today to mainly across the E/SE. As we begin to lose heating, rain and storms will start to dissipate. /JNE/ Tuesday through early next week... Tuesday, we will begin to see a pattern change as the upper ridge breaks down, allowing for a less subsident regime and increased flow aloft. Residual moisture will be sufficient to support thunderstorms Tuesday afternoon with PWAT values around 1.7 inches and dewpoints in the lower 70s. Convective parameters suggest some of these storms could be severe, particularly south of I-20, with vertical totals around 27 and SBCAPE around 3000 j/kg. Given slow corfidi vectors and high PWAT values, locally heavy downpours are possible. Late Tuesday into Wednesday a cold front sags southward. The front doesn't appear to clear the area until Wednesday night, allowing for residual moisture to remain in place across southern portions of the area Wednesday afternoon, which will be supportive of thunderstorms. Convective parameters are less than ideal and storms are likely to remain subsevere. Drier air in the wake of the front (PWAT around 1 inch) will likely keep things dry Thursday. The moisture rebounds Friday into Saturday as a surface high pressure over the Gulf will provide for return flow. A more prominent cold front swings through Saturday afternoon and rain and storms will be possible ahead of the front given sufficient moisture and heating. At this time, it does not appear that severe weather will be associated with this front amid weak convective parameters. In the wake, conditions should be cooler and drier heading into early next week./SAS/ && .AVIATION... (18Z TAFS) Issued at 1251 PM CDT Mon May 15 2023 Isolated to scattered SHRA and TSRA are expected across areas mainly along and east of the Interstate 55 corridor before 00Z Tuesday, with chances quickly decreasing after that time. Gusty winds will be possible near TSRA, but otherwise expect light winds to prevail. Increased humidity overnight could lead to some patches of BR or FG, with best confidence for MVFR or lower impacts to be at KHBG and KPIB after 06Z and clearing by 13Z-14Z Tuesday. /NF/ && .PRELIMINARY POINT TEMPS/POPS...
