.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.
