.NEAR TERM... (Rest of today and tonight) Issued at 1258 PM CDT Fri Sep 12 2025
The weather pattern continued to be dominated by the upper ridge over the southern Plains and the associated warm weather. We will see some cumulus this afternoon, especially in the east and south, and some cirrus, but no significant weather is expected.

.SHORT TERM... (Saturday through Sunday night) Issued at 1258 PM CDT Fri Sep 12 2025
A longwave trough across the western United States shifts slowly east toward the Rocky Mountain region Saturday. Through the day Saturday it remains too far west for us to see any significant precipitation chances, but it does push the upper ridge east of us - and so high temperatures on Saturday may be a degree or two lower with slightly lower heights and thicknesses over the area. This approaching trough will aid in the development over the High Plains on Saturday afternoon, and some of these storms will approach western portions of the forecast area late Saturday night. The trough then ejects into the central and northern Plains taking much of the lift north with it, so thunderstorms will remain possible in the in the west as this trough ejects, but we do not expect the storm chances to spread too far east.

.LONG TERM... (Monday through Thursday) Issued at 1231 AM CDT Fri Sep 12 2025
At least some weaker ridging aloft will move back in next week, keeping afternoon temperatures from getting below the upper 80s. Medium range models would suggest a breakdown of the ridge by midweek, with additional rain chances possible across much of the area.
