Area Forecast Discussion National Weather Service Jackson MS 317 PM CDT Mon Jun 1 2026 ...New DISCUSSION... .KEY MESSAGES... - Isolated to scattered severe thunderstorms will be possible this afternoon into tonight; with a Slight Risk across the north and a Marginal Risk for severe storms over central and southern portions of the area. - There is a Limited threat for dangerous heat stress today with heat index values peaking near 105 degrees. - Seasonal temps (highs: low/mid 80s & lows: ranging in the 60s) and dry air will follow post frontal boundary Tuesday night. - Rain potential will return over the weekend && .DISCUSSION... Issued at 303 PM CDT Mon Jun 1 2026 Through Tuesday: Latest satellite imagery/RAP analysis showed a mid level ridge axis to our west that was resulting in a northwest flow across the CWA. This northwest flow was supporting an MCS moving south across northern Alabama. The western portions of this MCS was spreading into our northeast most zones. Severe storms capable of damaging wind gusts and some hail will be possible with this activity this afternoon. Elsewhere across the CWA microburst pulse severe storms are possible as local microburst checklist showed microbursts will be likely this afternoon considering the anticipated atmospheric parameters. In addition latest guidance still showed additional development across the northern portions of our CWA this evening along the boundary leftover by the current MCS. The main threat for severe through this evening will remain damaging wind gusts although hail and locally heavy downpours. A Severe Thunderstorm Watch has been issued for our northeast this afternoon but an additional Watch or an expansion of the current Watch is possible this evening due to the potential of more organized convection dropping through our CWA. In addition, with the heat and humidity across the CWA away from convection, peak heat index values will be around 105F in may areas this afternoon. This area is outside of our northeast due to the ongoing convection. It's possible the convection tonight will last past midnight across the southern portions of our CWA. Tuesday a >1028mb high will drop out of Canada and become centered over the Great Lakes region. This will bring cooler and drier air into the northern portions of our CWA. This will result in the highest heat indices and greatest rain chances across our southern zones Tuesday afternoon. /22/ Tuesday Night through Sunday: Once the trough shifts south, the frontal boundary will push through the region Tuesday afternoon. Drier air will provide relief from the heat over the last few days as high/low temps feel closer to early June (near seasonal average). High pressure will settle over the Great Lakes, traversing southward over the week and provide a ridging pattern for our region. Heading into the weekend, the high will shift towards the east, winds will shift to the south/southeast, increasing humidity across the area. With increasing humidity, 40-75% rain chances return over the weekend with the greatest chances in the south/southwestern portion of the ArkLaMiss region. /SW/ && .AVIATION... (18Z TAFS) Issued at 1253 PM CDT Mon Jun 1 2026 VFR conditions wl prevail through the aftn into the evening but local radars were showing isolated to scattered SHRA/TSRA developing across the north that wl increase in coverage and affect TAF sites. Once the TSRA dissipate toward 06Z VFR conditions wl prevail until 11Z when MVFR cigs wl develop. MVFR cigs wl prevail until improving after 16Z. /22/ && .PRELIMINARY POINT TEMPS/POPS...
