KEY MESSAGES

Updated at 609 AM CDT Mon Jun 1 2026

- Showers/storms possible Monday afternoon/night, especially across parts of northern OK. Some of the storms could be severe.

- Hot temperatures expected Monday.

- Rain/storm chances continue through the rest of the week into next weekend.

NEAR TERM

(Through Monday) Issued at 132 AM CDT Mon Jun 1 2026

Storms that developed in northern OK late this evening are expected to diminish over the next few hours. There is some uncertainty on how the rest of the night into early Monday will go but at least most of the area is expected to be dry overnight. However, there is a low chance for some isolated showers and/or storms to develop through the night into early Monday. Temperatures will remain warm overnight with morning lows in the upper 60s (NW OK) to the mid 70s in south central OK.

Models show the upper ridge continuing over the region Monday with a shortwave/mid-level disturbance moving into western KS late Monday afternoon. At the sfc, a sfc low is expected to develop in SE CO/NE NM Monday afternoon with a dryline expected to extend across western portions of the fa. Higher storm chances are expected to begin Monday afternoon and continue into Monday night. Some storms could develop in the area along the dryline Monday afternoon. However, models show more scattered activity developing in KS and northern OK Monday afternoon/evening as the previously mentioned shortwave/disturbance moves into KS. CAPE values of 2000-4000 J/kg could develop making severe storms possible with large hail and damaging winds possible.

Hot temperatures will be another concern today with the upper ridge over the region and plenty of sunshine. Highs Monday afternoon will once again climb into the 90s to triple digits. Humid conditions in eastern portions of the fa could lead to max heat index values 100- 105 generally along and east of I-35 Monday afternoon which would have an impact on outdoor activities.

SHORT TERM

(Monday night through Wednesday night) Issued at 132 AM CDT Mon Jun 1 2026

The thunderstorms that develop in KS/N OK Monday afternoon/evening could develop into a complex that moves SE/S across portions of the fa Monday night into Tuesday morning. These storms will push a boundary southward Monday night with the boundary expected to extend across portions of the area by Tuesday afternoon. Showers/storms will remain possible across portions of the area Tuesday into Wednesday with the highest chances shifting to western portions of the fa Tuesday night into Wednesday. Enough instability could develop for strong to severe storms to be possible again Tuesday. Locally heavy rain/flooding will also be a concern.

Temperatures Tuesday are expected to be warm/hot with highs in the upper 80s to mid 90s although there is some uncertainty with this temperature forecast due to where the rain and clouds will be. Models show the upper ridge shifting eastward Wednesday leading to "cooler" temperatures with highs Wednesday afternoon in the 80s across the area.

LONG TERM

(Thursday through Sunday) Issued at 132 AM CDT Mon Jun 1 2026

Active pattern will continue with showers/storms remaining possible across at least parts of the area for the rest of the week into next weekend. With the rain/clouds, temperatures are expected to remain around average for early June for the rest of the week into the weekend as well.

AVIATION

(12Z TAFS) Issued at 609 AM CDT Mon Jun 1 2026

South or southeast winds are expected to prevail across the area today and tonight. Scattered thunderstorms are expected to develop across northern into central OK this afternoon into this evening, with potential for gusty and erratic winds in vicinity of thunderstorm activity. Storms may continue into the overnight period, with the best chance for this across north-central OK.
