KEY MESSAGES

- Showers and thunderstorms could bring locally heavy rainfall to portions of the area this afternoon and evening.

- Monitoring the potential for increasing heat stress later this week.

DISCUSSION

Issued at 124 PM CDT Sun Jun 7 2026

Tonight through Saturday...Scattered to widespread showers, along with some thunderstorms, will remain likely across the forecast area into this evening. While there will be some lessening in coverage overnight, some isolated to scattered convection will remain possible across mainly northern portions of the area into early Monday morning, as a shortwave lifts northeast through the Mid-South region. Some heavy downpours will remain possible for the remainder of this afternoon into this evening. This will result in the ponding of water in low-lying and poor drainage areas, especially where convection trains across the same locations.

This deeply moist airmass will persist across the region during the week. The bulk of the rain chances will exit the CWA with the aforementioned shortwave, with ridging increasing across the region. However, given the airmass now residing over the forecast area, an isolated diurnally driven shower or storm will remain possible each afternoon. It'll also be during this time where the concern for dangerous heat stress will be on the rise. By the time Tuesday rolls around, and continuing through Saturday, with highs warming into the 90s and dew points well into the 70s, afternoon heat index values currently look to reach and eventually surpass the century mark. If the trend continues, at a minimum, a "Limited Threat" for said dangerous heat stress could become necessary as early as Wednesday for portions of, if not all of, the forecast area, and potentially be needed for consecutive days heading into the weekend. /19/
