964 FXUS64 KJAN 110706 AFDJAN Area Forecast Discussion National Weather Service Jackson MS 206 AM CDT Wed Jun 11 2025 ...New DISCUSSION... .DISCUSSION... Issued at 206 AM CDT Wed Jun 11 2025 The main message for the back half of this week into early next week is hot and humid with summery chances for mainly afternoon/evening showers and thunderstorms. In one word - "June." Temperatures should actually fairly seasonable - highs around 90 and lows in the lower 70s. The upper-level weather pattern will feature troughing generally over our region, as a weakness persists beneath ridge centers over the Desert Southwest and off the Southeast U.S. coastline through the 7-day time frame. Southerly low-level flow around the Bermuda High will keep humidity levels around 70% through afternoon hours, and drippy overnight. A closed low lifting from the Southern High Plains toward Missouri by Saturday will be the instigating feature for anything more organized as far as thunderstorm potential over the next few days. But the combination of heat and humidity and flow in the region will generally support 60-80% rain chances across the forecast area Thursday onward. With the humidity arriving from the south, falling from above, and simmering out of the ground, 100+ heat index values should become increasingly common this weekend into early next week. Limited to Elevated heat stress graphics may be needed over the next few days, but it`s always worth keeping in mind that summer in the South is a time to stay hydrated, wear comfortable and cool clothing, and check on family and neighbors who may need cool places to stay during hot afternoons and muggy nights. /NF/ && .AVIATION... (06Z TAFS) Issued at 1253 AM CDT Wed Jun 11 2025 Patchy BR or low stratus can`t be ruled out where more humid air resides overnight, mainly at TAF sites along the I-59 to Hwy 84 corridors (MEI, HBG, PIB and psbl at HEZ). Confidence is most likely for IFR to LIFR flight category stratus and MVFR vsby/BR at PIB and HBG, while less pessimistic at MEI and temporary restrictions from MVFR stratus at HEZ. Mixing should lift out any restrictions by 11/13-15Z Wednesday. SHRA and TSRA will redevelop in the aftn to evening hours, with potential earliest onset between 11/15-17Z, while most likely between 11/18-23Z. Sfc winds should remain light and variable, some southeasterly, generally sustained and gusts under 10mph. /DC/ && .PRELIMINARY POINT TEMPS/POPS...
