042 FXUS64 KJAN 031853 AFDJAN Area Forecast Discussion National Weather Service Jackson MS 153 PM CDT Fri May 3 2024 ...New AVIATION... .MESOSCALE UPDATE... Issued at 952 AM CDT Fri May 3 2024 A short wave is moving into the area this morning along with showers/storms. These storms will continue to move across the area this morning through the afternoon hours along with the showers/storms. With marginal lapse rates/instability expect these storms to remain below severe limits, but a strong storm or two will be possible. Highs will range from the upper 70s to low 80s across most of the area./15/ && .DISCUSSION... Issued at 409 AM CDT Fri May 3 2024 Today and Tonight: Continued warmer than normal temperatures along with decent rain chances are expected through tonight. A rather weak surface ridge will continue to nose across our CWA from the east while the southern branch of the jet stream continues overhead resulting in southwest flow aloft. This will maintain our warm moist airmass with PWATs greater than an inch and a half along with mid to upper 60F dewpoints. Subtle disturbances within the southwest flow aloft will combine with our moist airmass and daytime heating to result in scattered to numerous coverage of showers and thunderstorms. The greatest coverage will be in our west and across our north. Although there will be a distinct diurnal trend to the convection, rain chances will linger tonight especially in the north. /22/ This Weekend: Isolated to scattered rain and storm chances will continue throughout this weekend, expect them to be in the mid-range (30-50%). An upper-level low moving east/southeast will send a cold front towards our area, nearing early Saturday morning with it being just west in the high plains. Storms and showers in the high plains will be strong and linear along the front, losing strength as they move east downstream, mostly dissipating by the time they reach our area. Remnant storm activity has the possibility of redevelopment in our area as heating occurs and instability increases by mid-day. Next week: By next week our weather pattern evolves into the typical western trough to eastern ridge pattern as temperatures will be abnormally hot. Southwesterly flow and surface ridging will help a strong surface high build into the ArkLaMiss region. Temperatures will be at risk of nearing record high temps for the month of May as they could be as high as the low to mid 90s range, this will be our first taste of summer-like temperatures. The next chance of rain will be the end of the workweek. Upper level troughing in the western plains will become negatively tilted and provide a source of multiple disturbances through late week. As a front pushes down into the region it is possible for some strong to severe storms to form along the front. This event is possible however confidence isn`t very high at this time as there is a good degree of uncertainty this far out in the forecast. /KP/ && .AVIATION... (18Z TAFS) Issued at 146 PM CDT Fri May 3 2024 A mix of VFR/MVFR/IFR conditions prevail across TAF sites this afternoon and this will continue through much of the day as showers/thunderstorms move across the area. The bulk of the storms will move east of the area this evening, but expect stratus/fog to develop overnight after 09-10Z with sites becoming IFR/LIFR. /15/ && .PRELIMINARY POINT TEMPS/POPS...
