KEY MESSAGES

Updated at 155 PM CDT Tue Oct 20 2026

- Warming trend this week.

- Isolated light showers through early Wednesday.

- Higher rain chances return this weekend and continue into early next week.

NEAR TERM

(Rest of today and tonight) Issued at 155 PM CDT Tue Oct 20 2026

Isolated high-based showers continue across the area, but the precipitation observed on radar is still having to fight low-level dry air acting to evaporate the rain, so much of this is virga. So far, no mesonet stations have recorded measurable precipitation. There is a shortwave moving into the area, so there will be continued support into the evening and overnight hours. With the low-level dry air, the expectation is that there will still be a lot of evaporation so probability of measurable precipitation is still rather low at any specific location. Will keep POPs below 20 percent, but include the mention of isolated showers.

SHORT TERM

(Wednesday through Thursday night) Issued at 155 PM CDT Tue Oct 20 2026

Some of the isolated showers may linger a little past sunrise across northern Oklahoma before diminishing. After this shortwave shifts east of the area Wednesday morning, the upper ridge across western Texas will build north into the southern and central High Plains which will dominate the weather pattern for the area mid- week. Temperatures will warm Wednesday and Thursday with no precipitation expected at all through Thursday thanks to this ridge.

LONG TERM

(Friday through Monday) Issued at 151 AM CDT Tue Oct 20 2026

The upper ridge will gradually shift east late this week into the weekend as the upper trough continues to slowly approach and eventually move across the Plains. Models diverge on the timing/evolution of this trough over the weekend into next week. However, right now it looks like the trough will bring a chance for some more rain and maybe some storms over the weekend into early next week. Currently, rainfall totals do not look as high (3+ inches) as what occurred in some areas with the last couple of rain events but some locations, primarily in western parts of the fa, might see as much as an 1 to 1.5 inches. The uncertainties of the timing/evolution of this system will have an impact on when/where rain chances will occur which could also have an impact on amounts so will have to wait and see how things come together.

Temperatures are expected to remain near or above average for late October over the weekend into early next week although with maybe a slight cool down early next week.

(18Z TAFS) Issued at 1210 PM CDT Tue Oct 20 2026
