KEY MESSAGES

Updated at 115 PM CDT Mon Jun 8 2026

- Severe thunderstorms will be possible late Monday across northwest Oklahoma.

- Hot & muggy conditions this upcoming week with heat indices near to above triple digits each day.

- More active period of showers and thunderstorms expected late this week through the weekend.

NEAR TERM

(Rest of today and tonight) Issued at 115 PM CDT Mon Jun 8 2026

Heat continues to be the main issue this afternoon as most locations have risen above the century mark wrt heat indices, with some in excess of 105 across northern Oklahoma.

In addition will continue to watch for a few high-based thunderstorms across northwest Oklahoma this afternoon as we reach max heating and a weak surface trough approaches the area. If storms do form they will have the potential to produce some damaging wind gusts and possibly some small hail. Any activity that does develop should dissipate with the loss of daytime heating.

For tonight it will remain breezy, warm and muggy as surface dewpoints remain in the lower 70s across much of the area. The higher dewpoints and breezy south winds will keep overnight temperatures in the mid to upper 70s.

Another hot, breezy and muggy day expected Tuesday. As the surface trough lifts back north, the windier conditions will include northwest Oklahoma, which had seen lighter winds Monday. Perhaps a degree or two lower dewpoints look to keep us just below Heat Advisory criteria Tuesday afternoon.

A larger-scale upper trough will move through the northern Rockies on Tuesday. As this occurs, storms are expected to develop across the High Plains of New Mexico and Colorado. These storms will make a run at northwest Oklahoma by late in the day, but are expected to dissipate as they approach the area.

SHORT TERM

(Tuesday through Wednesday night) Issued at 115 PM CDT Mon Jun 8 2026

The aforementioned upper trough will continue to make its way across the central and northern Plains on Wednesday, meanwhile the associated surface front will approach northern Oklahoma by late in the day. Tighter surface pressure gradient ahead of an approaching front will make for even stronger winds on Wednesday. In addition, a low level thermal ridge ahead of the front will result in a warmer day as well. This combination will likely necessitate the need for heat headlines across northern Oklahoma.

Although the stronger forcing will remain well to the north of the area, sufficient heating and convergence along the front may provide a chance for an isolated storm or two near the Kansas border late Wednesday afternoon and evening. This front is expected to lift back north Wednesday night.

LONG TERM

(Thursday through Sunday) Issued at 222 AM CDT Mon Jun 8 2026

The trend in the medium-range models has been to keep stronger zonal flow over the area as a broad trough slowly moves east across Canada and the United States late this week. While temperatures will remain very warm, they may not be quite as hot late in the week as early this week. Precipitation chances increase Thursday night as the main trough axis moves over the Plains and a surface front approaches or moves into northern Oklahoma. Storm chances persist through the weekend.

AVIATION

(18Z TAFS) Issued at 1220 PM CDT Mon Jun 8 2026

Scattered to broken cloud cover continues along an axis near and east of I-35. Cloud bases have been slowly rising through the morning and fully VFR conditions are not far away, but don't be surprised to see a few 3,000 foot BKN ceilings early this afternoon. Otherwise, gusty southerly winds will abate slightly this evening with the signal for tomorrow morning suggesting that low-level stratus will likely remain to our east.
