- Hotter and drier into the weekend and the week beyond.

MESOSCALE UPDATE FOR THUNDERSTORMS

... Issued at 1116 AM CDT Thu Jun 25 2026

Today's situation is somewhat complex. The TAFs are going to be a little messy as well. However, here's the current setup: Surface Low pressure center is in SW Kansas, with a trough / psuedo-dry line extending to the south and west into West Texas. Also from the low center, there is a warm front which stretches from the low from Beaver...to Guthrie...to Fort Smith. Well north of here, there's a cold front, stretching from NE Colorado through central Kansas, then eastward into Missouri.

There is a narrow corridor of surface based CAPE in excess of 2500 J/KG which ranges from Woodward to Ada. 850mb Theta-e ridge extends SW to NE from Childress to Stillwater, while severe weather parameters are beginning to highlight northwestern and northern Oklahoma for this afternoon.

All of these features will have an influence on today's weather and forecasts, so am giving an overview here...and this probably won't the last mesoscale update for the day.

NEAR TERM

(Rest of today and tonight) Issued at 1235 PM CDT Thu Jun 25 2026

Thunderstorms and potential severe convection are the main topics for today and again tonight. Mesoscale section has the pertinent details of the features to be watched.

For the next few hours, there's a little bit of a lull in the action. Even so, there will be echoes on radar most of the afternoon. Areas in northwest and north central Oklahoma will be primary area to watch, as the combination of instability, shear and boundaries are maximized there. However, as there are surface boundaries in several locations from earlier storms...severe thunderstorms are possible anywhere within the slight risk area.

Rain / thunderstorm chances begin in the next hour in the north, before drifting west and south by the end of the afternoon.

SHORT TERM

(Friday through Saturday night) Issued at 1235 PM CDT Thu Jun 25 2026

After temperatures in the upper 80s today, Friday and Saturday will be days where the warmup will begin. Highs will be rise into the lower 90s on Friday (for most areas) and into the mid to upper 90s by Saturday. Over the past week, we have had dew points in the 70s, and there won't be much relief in the low level moisture, despite the clearing skies. In other words, the humidity will be borderline oppressive for both days, but especially on Saturday.

LONG TERM

(Sunday through Wednesday) Issued at 157 AM CDT Thu Jun 25 2026

The main long-term story continues to be the potential for a consistent and possibly long-duration heatwave across our area. Global, ensemble, and AI-based guidance all indicate an amplification of the ridge to our east beginning on Sunday and lasting through (beyond) the end of the long-term period. Because of that, precipitation chances are going to be slim to nil during that timeframe. Not only will air temperatures and heat indices approach Heat Advisory criteria most days, but overnight lows will be little relief, sitting near 80 in most spots.

AVIATION

(18Z TAFS) Issued at 1116 AM CDT Thu Jun 25 2026

See the Mesoscale update portion for th e overview of all the things going into the forecast, but for the early part of the TAFs, there will be a slight lull. MVFR or IFR ceilings will be the rule for most terminals until late this afternoon or around 00Z. Thunderstorms will be more likely in the north, with Prob30 groups included for KOKC and KOUN. After the storms, the upper winds become strong out of the southwest, leading to some potential for low level wind shear.

By 11Z Friday, most of the activity will be waning, giving way to VFR ceilings and improved conditions.
