     this afternoon and evening, with low precip chances

     persisting overnight. A storm or two may produce strong to

     marginally severe wind gusts today.

     heat indices of 95-105 F across the area.

.SHORT TERM...

(Tonight)

Issued at 140 PM CDT Thu Jun 26 2025



Plume of deeper moisture has expanded across E OK and is

downstream of the subtle weak wave extended through NW OK. These

elements combined with ample heating will support isolated to

scattered storms later this afternoon through early evening with

the higher chances northwest of Interstate 44. Locally strong

downburst winds will be possible with any stronger storms. The

convection may wane this evening but bulk of guidance maintains

a signal for continued precip chances through the overnight hours

into early Friday.

.LONG TERM...

(Tonight through Thursday)

Issued at 140 PM CDT Thu Jun 26 2025



Weak sfc boundary slides into the forecast area tomorrow while

remnant troughing remains aloft as the upper ridge has weakened.

A broader expanse of deep moisture will also be present and

expectation is shower and storms will be ongoing early Friday

steadily expand in coverage through the afternoon with a drift to

the east and south. Any stronger storm will be capable of locally

gusty winds. Heavy downpours should be expected with the slow

storm motions.



Storm chances continue on Saturday but overall lesser coverage is

expected. Another glancing influence from a passing wave aloft is

likely to increase shower and storm coverage Sunday into Monday.

Overall temps and afternoon heat index values expected to remain 

near seasonal normals. Outdoor activities should be mindful of 

lightning safety through the weekend.

.AVIATION...

(00Z TAFS)

Issued at 607 PM CDT Thu Jun 26 2025



Potential on station thunderstorm impacts will be the main concern

through the period. Ongoing thunderstorms west of BVO/TUL/RVS are

slowly moving eastward toward these 3 terminals, with a low but

mentionable chance of impacts during the first 4 to 6 hours. While

this activity may fester some, it should come down in intensity.

The next best potential for thunderstorm impacts will be the last

4 hours of the valid TAF period, with MLC and the W AR sites

having mentionable potential at this point as well. Will include

PROB30 groups for this activity. In between these two main time

frames, a lower chance for thunderstorms will exist but will not

include a mention at this time. Wind gusts should be less

prevalent tomorrow afternoon than today.
