247 FXUS64 KJAN 190927 AFDJAN Area Forecast Discussion National Weather Service Jackson MS 427 AM CDT Wed Jun 19 2024 ...New DISCUSSION... .DISCUSSION... Issued at 425 AM CDT Wed Jun 19 2024 Today and Tonight...Strong high pressure at the surface and aloft, centered east of the region, will both continue to build west into the region. This will result in easterly flow across the CWA, which will continue to advect a slightly drier airmass into the forecast area. This will also cause any chance for showers this afternoon and evening to be confined to far southern portions of the CWA. High clouds will maintain their presence across much of the area today, but a few peaks of sun will again be seen across the area through the course of the day. Highs today will be a touch warmer as they range from the upper 80s to lower 90s. For tonight, some high clouds will linger across the area as lows range from the upper 60s to lower 70s. /19/ Through Late Week...Anomalously strong 595 dam mid-level ridge will have expanded from its origins over the mid-atlantic states into much of the mid MS valley. The stout ridge will provide a rather dry airmass aloft limiting the potential for storm coverage as chances for isolated showers and storms will remain confined to the afternoon as peak heating occurs and mainly focused along our far southern counties. This pattern will repeat daily through late week. This Weekend into next Week...Ridging at the surface and aloft will help mitigate rain chances as the more moist tropical airmass will be in place further west southwest as the potential tropical disturbance continues its track west through Mexico. An influx of deep layer will result in dewpoints recovering into the high 60s to low 70s by Saturday. We can expect to see seasonably warm temps with mid 90s high temperatures expected through late week. It is also worth noting that heat indices will near 105 degrees and there will be a chance for triple digit temps this weekend into next early week thus heat products will be likely heading into the weekend. Looking ahead to next week week we can expect to see and active tropics as another area of low pressure is forecasted to form in the Southwestern portions of the Gulf Of Mexico following tropical cyclone one. At this time it is unlikely that our area sees any impacts as the system is forecasted to track west- northwestward or northwestward./KP/ && .AVIATION... (06Z TAFS) Issued at 1220 AM CDT Wed Jun 19 2024 Despite high clouds over the region, VFR flight categories will prevail at most area TAF sites over the next 24 hours. Some patchy low stratus will be possible toward day break over namely KMEI, KHBG & KPIB. This could briefly bring ceilings to MVFR status between 10-13Z. This will quickly erode shortly after sunrise, with a return to VFR categories expected through the remainder of the forecast period. Winds overnight will be calm to light from the west northwest around 3-5 knots. Winds will increase from the east around 10 knots by late morning, with gusts around 20 knots possible. /19/ && .PRELIMINARY POINT TEMPS/POPS...
