Issued at 1233 AM CDT Tue Jun 16 2026 - Temperatures will rebound to the upper 80s to near 90 by Wednesday, along with higher humidity levels. - We are monitoring tropical activity that may bring heavy rainfall to the Mid-South Thursday and Friday. && .DISCUSSION... (Today through Monday) Issued at 1233 AM CDT Tue Jun 16 2026 Mostly clear skies prevail across much of the Mid-South as weak high pressure covers the region. Clouds associated with the stalled front to the south have worked into north Mississippi, though any rain remains to the south this evening. Some drier air has managed to work into the northern half of the Mid-South, where dewpoints are in the lower to mid 60s, making for a comfortable evening. The stalled front to the south will wobble a bit and push a few showers into north Mississippi over the next couple of days, mainly south of a Clarksdale to Tupelo line, where there is a 40- 60% chance of one-quarter inch of rain by Wednesday afternoon. Elsewhere, expect mostly dry weather and warming temperatures. Highs will reach the mid 80s on Tuesday and close to 90 by Wednesday. An upper-level disturbance moving through the Mid- Mississippi and Ohio Valleys will bring a small chance (15-25%) of showers to areas along the KY/MO borders late Tuesday afternoon into the evening hours. The NHC is forecasting a 50% chance of tropical cyclone formation in the NW Gulf over the next couple of days. Operational models lift the remnants of this system northeast into the Lower Mississippi Valley by Thursday and Friday while a cold front approaches from the northwest. Deep moisture will accompany the tropical feature with precipitable water values around 2 inches. Latest runs seem to push the system more to the east rather than north as it encounters the westerlies, which may keep the heavier rain confined to northeast Mississippi, where 2 to 4 inches is likely. A Flood Watch may be needed for parts of the Mid-South later this week. The remnants of the tropical system will push east, and a cold front will move through the region on Friday. This will set the stage for a dry and mild Saturday with highs in the mid to upper 80s and reasonable humidity. The front will lift back north as a warm front by Saturday night as low pressure develops over the Plains. Chance pops and high humidity return for Sunday as we move back into the warm sector, though there is not much to trigger storms with the main energy still well NW of the region. Unsettled weather returns early next week as another cold front approaches. && .AVIATION... (06Z TAFS) Issued at 1233 AM CDT Tue Jun 16 2026 VFR conditions prevail at all terminals with CIGs creeping northward across northern Mississippi. METAR observations as of 06z show some MVFR CIGs over central Mississippi, but guidance is not keen on bringing these to either MEM/TUP in this period. Some light rain showers are possible through 12z at TUP. A cold front will approach from the north through Tuesday, bringing a low (30%) chance of showers or thunderstorms to JBR, which are expected to dissipate before reaching MEM/MKL during the evening. CIGs will then begin to drop into MVFR at TUP, but are not expected to reach any other terminals through the end of the period. && .FIRE WEATHER... Issued at 1233 AM CDT Tue Jun 16 2026 Recent wetting rains and elevated humidity levels will preclude fire weather concerns this forecast period. In addition, wetting rain chances will return by the end of the week. && .MEG WATCHES/WARNINGS/ADVISORIES... AR...None. MO...None. MS...None. TN...None. && $$ PUBLIC FORECAST...SJM AVIATION...JAB
