KEY MESSAGES

Updated at 130 PM CDT Tue Jun 30 2026

- Hot and breezy conditions to continue this week.

- Excessive heating will return Friday & especially on Independence day with heat indices exceeding 105 degrees

- Some relief from the excessive heat Saturday night into Monday when our next opportunities for rain/storms chances return.

NEAR TERM

(Rest of today and tonight) Issued at 130 PM CDT Tue Jun 30 2026

Southerly surface flow will increase this afternoon, aided by strengthening troughing along the lee of the Rockies. Sunny skies today will give way to afternoon highs in the mid to upper 90s, even reaching near 100 F across southwestern Oklahoma and adjacent western north Texas. Dewpoints in the low 60s will help modulate the heat indices this afternoon, but even so, they will still get up to near 100 F.

Showers and storms are expected to develop across the higher terrain in TX/OK Panhandles this afternoon, and shift towards the east through the evening hours. As these storms move into the northwestern portions of the area, they are expected to weaken; however, there is a low chance that they may be strong enough to produce large hail and damaging wind gusts. Any storm activity is expected to diminish by midnight.

SHORT TERM

(Wednesday through Thursday night) Issued at 130 PM CDT Tue Jun 30 2026

We will see a similar pattern on Wednesday as we did on Tuesday. Breezy southerly winds will continue through the day across the entire area. Increasing moisture and cloud cover may help afternoon temperatures be a few degrees cooler than on Tuesday, but heat indices will remain in the upper 90s. There is a signal for storms to develop across the higher terrain again Wednesday afternoon, and may impact portions of western and northwestern Oklahoma by Wednesday evening. Large hail and damaging wind gusts will be the primary hazards with this activity Wednesday evening.

Afternoon temperatures on Thursday will once again be similar as the days preceding. Generally, the overnight lows through the middle of the week will be in the mid to upper 70s across the area.

LONG TERM

(Friday through Monday) Issued at 116 AM CDT Tue Jun 30 2026

Our weather pattern does start to change on Friday as the upper troughing breaks down across the U.S. Southwest with ridging building and expanding eastward over much of the entire southern half of the country. The increasing pressure heights on Friday will start two days of excessive heating going into Independence Day (Saturday). As a result will see high temperatures rise to triple digits with heat indices exceeding 105 degrees especially on Saturday which could prompt our next Heat Advisory. By Saturday night could see a cold front push down at least through the Central Plains interacting with weak troughing in the ridging. This may initiate storm activity in Kansas going into northern Oklahoma Saturday evening and our entire Oklahoma/Texas area Saturday night into Sunday and Monday. The potential rain/storms Sunday & Monday should bring some temperature relief from the 2-day excessive heating trend with afternoon highs below triple digits.

AVIATION

(18Z TAFS) Issued at 1155 AM CDT Tue Jun 30 2026

VFR ceilings again this TAF period with some mid and high clouds especially across portions of western OK. S to SW gusty winds this afternoon will back to the S and SE this evening before shifting back to the S and SW Wednesday. LLWS once again is expected at some TAF sites tonight. There is a low chance for a few storms to move into parts of western OK this evening. If this occurs, KWWR would have the highest (20-30%) chance of storms affecting the site. However, strong variable winds out of the storms may affect KCSM as well.
