KEY MESSAGES

Updated at 618 AM CDT Sat May 30 2026

- Hot into early next week with triple digit temperatures possible in some locations.

- Rain/storm chances return Monday and continue through the rest of next week.

NEAR TERM

(Through Saturday) Issued at 150 AM CDT Sat May 30 2026

An area of showers/storms continues to weaken as it moves east across central portions of the area. Gusty winds will be possible with this activity. Meanwhile, WAA showers/storms will also be possible across portions of northern OK overnight into early Saturday.

Models show a shortwave moving into the central Plains Saturday afternoon with a 500 mb speed max potentially moving from the Big Bend are NW across west TX towards SW portions of the fa. At the sfc, a dryline is expected to develop/move into western portions of the fa by late Saturday afternoon. Lift associated with the shortwave is expected to be in KS into parts of northern OK with scattered showers/storms possible as the ascent moves across the region. There is more uncertainty with development further south along and east of the dryline. However, lift associated with the dryline and heating could be sufficient for some storms to develop along the dryline. Storm development could also be aided by the 500 mb speed max that some models show moving towards the area.

The environment east of the dryline will make severe storms possible late this afternoon and evening with the moist, unstable airmass expected to have CAPE values in the 2000-4000 J/kg range. Damaging winds and large hail will be the primary concerns. The showers/storms are expected to diminish Saturday evening.

Another warm/hot day is expected again today with much of the fa expected to climb into the 90s this afternoon.

SHORT TERM

(Saturday night through Monday night) Issued at 150 AM CDT Sat May 30 2026

Models show an upper ridge beginning to build over the region Sunday and continuing into next week although models show this as being a bit of a "dirty" ridge with several disturbance meandering across the southern Plains under the ridge. Currently the forecast is dry for Sunday as the ridge begins to build but a few models are beginning to hint that a few showers/storms might be possible Sunday evening/night. Will have to see if this trend continues. If it does then some rain chances may need to be introduced to the forecast.

There is a better signal for a chance for showers/storms Monday afternoon/night. Models show a warm front extending west to east across parts of the area (right now it looks like northern OK) by Monday afternoon. Shower/storm development will be possible near this front. Strong to severe storms will be possible with CAPE values of 2000-4000 J/kg possible Monday afternoon.

Hot days and warm nights are expected Sunday and Monday with highs in the 90s to triple digits and lows in the upper 60s to mid 70s.

LONG TERM

(Tuesday through Friday) Issued at 150 AM CDT Sat May 30 2026

Models show the upper ridge shifting eastward towards the middle to end of next week with various shortwaves/disturbances moving through the southwest flow. This will maintain rain chances across at least parts of the fa through the end of the week. Temperatures will cool slightly with highs more in the 80s to low 90s.

AVIATION

(12Z TAFS) Issued at 618 AM CDT Sat May 30 2026

Scattered showers and storms continue to develop across portions of northern OK this morning, mostly expected to impact KPNC, with a lower probability at KWWR/KSWO. Additional chances for scattered storms are expected across more of the area this afternoon into this evening. Winds will increase from the south and become gustier this morning into this afternoon, then decrease this evening through tonight.
