KEY MESSAGES

- Dangerous levels (limited to elevated) Saturday.

- "Marginal Risk" (Level 1 of 5) of isolated severe storms for portions of the area both Saturday & Sunday.

DISCUSSION

Issued at 205 PM CDT Fri Jul 10 2026

Rest of today: The remainder of the day will remain relatively dry with isolated chances for showers mainly across southern portions of the area as the sub-tropical ridging continues to expand into the area. Abnormal heat and humidity will persist through this evening areawide with the far northern counties of the forecast area remaining under a heat advisory through 8pm tonight, additionally we will continue to indicate the risk for elevated (level 2/4) and limited (level 1/4) risk areas for dangerous heat stress in the hazardous weather outlook graphics into this weekend./KP/

Over the upcoming weekend, the aforementioned sub-tropical ridge will weaken and slide further west of the forecast area. This will yet again allow troughing/low pressure aloft to become the primary weather feature across/near the CWA through much of the remainder of the forecast period. Beginning Saturday, rain chances will begin increasing across the forecast area, with very good chances continuing each day through at least the middle of next week.

In addition, with a bit more northwest flow aloft setting up across the region during the weekend, attention will need to be paid upstream for any complex of storms that could potentially affect the CWA. The first of such could come late Saturday as a complex is currently progged to drop southeast and potentially into far northern portions of the area. As a result, a "Marginal Risk" for isolated severe storms now resides in the vicinity of the Highway 82 corridor for late Saturday afternoon into Saturday evening. Damaging wind gusts will be the primary concern with such storms.

As a frontal boundary tries to settle into the region late Sunday into early week, we'll again maintain good chances for showers and storms across the area. South of this boundary, a very moist and unstable airmass will continue to reside across the CWA. Another "Marginal Risk" for isolated severe storms capable of producing damaging wind gusts will again exist across much of the CWA on Sunday as a result.

Although this boundary will eventually washout, due to the overall troughing/low pressure pattern over/near the region, combined with the continued humid and unstable airmass, these rain chances will persist into at least Wednesday. Of course with these better rain chances, some relief from the ongoing heat stress will exist Sunday through at least next Wednesday. Finally come Thursday, ridging aloft reasserting itself over the region from the east is progged to lessen said rain chances late next week. /19/
