Area forecast discussion, Jul 28, 12:34 PM CDT, 44 minutes before
Area Forecast Discussion National Weather Service Jackson MS 1234 PM CDT Sun Jul 28 2024 ...New AVIATION... .MESOSCALE UPDATE... Issued at 935 AM CDT Sun Jul 28 2024 Not much to talk about in regards to the forecast package for this morning. Global guidance continues to highlight an upper low to the northwest and building high pressure over the northern Gulf. This will help maintain SW flow regime over the area today with continued rain chances (between 40-45%) and afternoon thunderstorms. Local radar scans show a line of scattered showers along with a few storms tracking northeastward across the MS Delta, along with a few parishes in northeast Louisiana. 12Z morning sounding observations indicate a saturated atmosphere with the air parcel breaking through the capping inversion around 950 mb. This will allow for mid-low level clouds to occur across central MS. A quick look at GOES 16 visible satellite imagery shows ongoing cloud cover across our entire forecast area. With this in mind, the persistent cloud cover will keep temperatures below seasonal norms with afternoon highs in the upper 80s in most locations. Areas in the southeast will see temperatures in the low 90s. /CR/ && .DISCUSSION... Issued at 430 AM CDT Sun Jul 28 2024 Today and tonight: Upper low to the northwest and high pressure over the northern Gulf will maintain SW flow regime over our area through today with continued rain chances and afternoon thunderstorms. Persistent cloud cover will keep temperatures mostly below seasonal norms with highs generally in the 80s in most locations, though we begin to see warmer temperatures today in the southeast (low 90s). Thunderstorms should taper off with waning instability late evening. Our SW flow regime finally begins to transition tonight to a warmer and drier pattern in store for next week. Dry air pushes into the midlevels as upper ridging begins to build from the west and should reduce rain chances from west to east through early Monday morning./SAS/ Monday through Saturday: A significant change in the weather pattern will take place for the upcoming work week into next weekend with wet and relatively mild conditions coming to an abrupt end while heat makes an unwelcome return. Confidence is high that a large, strong subtropical high will build over the Southern Plains with a ridge axis extending eastward across the lower MS Valley as we go through this week. With H850 temperatures reaching the lower 20s deg C, surface temperatures should have no trouble reaching the upper 90s to perhaps near 100. And after the very wet pattern recently experienced, evapotranspiration should support a very humid boundary layer in the increasingly stagnant airmass and a stifling combination of heat and humidity. In terms of rainfall, the increased large scale subsidence and anticyclonic flow should help to limit diurnal convective rainfall coverage. For now have increased the heat risk level in the hazard graphics to "elevated" for Monday and maintained that through the remainder of the forecast. It is likely that some portions of the area will need to be increased to the "significant" level, especially by mid/late week. Stay tuned for hot weather headlines with heat advisories being necessary as early as Monday, and perhaps excessive heat warnings later in the week. /EC/ && .AVIATION... (18Z TAFS) Issued at 1234 PM CDT Sun Jul 28 2024 Current radar scans show some isolated showers and storms near the Pine Belt. With that in mind, all TAF sites will see VFR conditions prevailing to start off the TAF period. VFR conditions will prevail across central MS through 23Z Sunday. Several southern sites (HBG, HEZ, and PIB) will start to see ceilings drop to MVFR starting around 00Z Monday as clouds continue to track to the east. These MVFR cigs will last until 02Z Monday. Ceilings will start to improve to VFR status by 03Z Monday. VFR conditions will continue to prevail across central MS through Monday morning. Winds will prevail from the southwest around 3 to 5 mph. /CR/ && .PRELIMINARY POINT TEMPS/POPS...
