830 FXUS64 KJAN 120550 AFDJAN Area Forecast Discussion National Weather Service Jackson MS 1250 AM CDT Wed Jun 12 2024 ...New AVIATION... .MESOSCALE UPDATE... Issued at 1019 PM CDT Tue Jun 11 2024 Another quiet weather night is on tap for the ArkLaMiss as only a few thin high clouds will stream across the region. No changes to the forecast were needed. /22/ && .DISCUSSION... Issued at 307 PM CDT Tue Jun 11 2024 Tonight through next Monday...A mid/upper shortwave will continue to shift east through the Lower Mississippi River Valley through tonight. As this departs, high pressure and ridging aloft will build into the region from the west and will remain in control of our weather through the remainder of the forecast period. As a result, quiet conditions will prevail across the forecast area through the remainder of the work week and into the upcoming weekend. By late Sunday into Monday, high pressure will reside east of the forecast area. Chances for isolated to scattered showers and storms will be on the increase across the forecast area during this time. This`ll be as a result of a slug of moisture, associated with a northward drifting wave, lifts into the gulf coast states from the Gulf of Mexico. The better coverage of convection will during the afternoon hours as a result of daytime heating, but some isolated activity will remain possible Sunday night and Monday night as our airmass will remain warm and unstable at that time. As far as temperature are concerned, a drier airmass will reside across the CWA Wednesday through Saturday. However, temperatures will steadily become warmer each day through the weekend. While lows tonight and Wednesday night will be in the 60s, as we get into the weekend they`ll be in the low and middle 70s. Then for highs, we`ll top out in the mid 80s to around 90 on Wednesday. However as Friday and the upcoming weekend rolls around, highs will top out in the mid 90s to around 100. These high temperatures Saturday into Sunday, factored with increasing moisture across the CWA during that time, could result in the threat for increased heat stress across portions, if not all, of the forecast area. This potential will continue to be monitored in upcoming forecasts, as a "Heat Advisory" may need to be hoisted for portions of the area. With good rain chances currently advertised over the CWA on Monday, highs will be held in check as they range from the upper 80s to lower 90s. /19/ && .AVIATION...
