KEY MESSAGES

Updated at 1249 PM CDT Mon Apr 6 2026

- Seasonable temperatures are expected through the middle part of this week.

- Breezy southerly winds will result in elevated fire weather conditions across northwest Oklahoma today through Wednesday.

- A more active pattern is expected to bring a return of showers and thunderstorms by the end of the week into early next week.

NEAR TERM

(Rest of today and tonight) Issued at 1249 PM CDT Mon Apr 6 2026

It is the official position of this meteorologist that today's weather qualifies as "beautiful". High temperatures in the low 70s, low humidity, abundant sunshine, and a southerly breeze: if you have outdoor plans this afternoon or evening, consider yourself lucky. The only anticipated weather impact this afternoon will be elevated fire weather in the northwestern corner of Oklahoma. Winds will be a little stronger there (15-20 mph sustained) and recent rainfall has missed the area.

Pure springtime conditions will continue tonight as temperatures drop into the low-to-mid 40s, with some upper 30s possible in the Washita, Canadian, and Cimarron Valleys.

SHORT TERM

(Tuesday through Wednesday night) Issued at 1249 PM CDT Mon Apr 6 2026

More of the same in the short term as surface troughing leads to relatively modest return flow tomorrow. Temperatures will be pretty similar, moisture content will be pretty similar, and winds will maybe be just a touch stronger, so elevated fire weather will persist in northwest Oklahoma.

A weak surface high will move into the northern Plains on Wednesday, and the easterly push of the pressure trough will move winds a little closer to due southerly. While temperatures will warm up a couple of degrees into the mid-70s, this will also bring in at least partial Gulf air. So while elevated fire weather could continue in a wind-driven environment in northwest Oklahoma, RHs will remain near or above 30 percent, tempering that concern.

LONG TERM

(Thursday through Sunday) Issued at 230 AM CDT Mon Apr 6 2026

By Thursday and Friday, instability will increase across the Oklahoma and north Texas as southerly winds advect moisture northward. The increasing low-level moisture should mitigate any fire weather concerns by the end of the week. At the same time, a couple surface boundaries may serve as the focus for the development of convection. A cold front will advance southward across the Plains as a shortwave trough moves across the Great Lakes region. The cold front (or the effective cold front) may approach northern Oklahoma with an increasing chance for showers and thunderstorms. In addition, showers and thunderstorms may develop along the dry line across the High Plains with the remnants of this convection moving into western Oklahoma and western north Texas.

This will be the start of an active synoptic-scale pattern that is forecast this weekend into early next week as southwest flow aloft likely develops across the Southern Plains. Southwest flow is favorable for synoptic-scale ascent and increased vertical wind shear in tandem with moisture advection and increased instability as shortwave troughs embedded within the flow lift into the Plains. As a result, there will be an increasing chance for showers and thunderstorms with some potential for severe weather and heavy rainfall/flooding. The active pattern will persist until the large-scale closed-low/trough across the southwest U.S. finally lifts into the Plains.

AVIATION

(18Z TAFS) Issued at 1108 AM CDT Mon Apr 6 2026

VFR conditions will continue areawide through the valid period. Occasionally gusty south winds are expected across western Oklahoma, with a generally light southeast wind persisting elsewhere. Increasing cirrus cloud coverage will be noted from west-to-east into Tuesday.

Safe travels!
